DeWalt has released some sweet new batteries over the past few years. They currently run two primary voltage platforms for their large cordless tools: 20-volts and 60-volts.
DeWalt 20v MAX And FlexVolt – What’s The Difference?
For those who haven’t been paying attention, DeWalt revolutionized cordless power tools in 2016 when they released the FlexVolt platform: the first-ever multi-volt battery system. FlexVolt batteries pack 60 volts to power highly demanding tools including DeWalt’s Atomic compact cordless tools, outdoor power equipment, work lights for the job site, saws, and nearly any tool in your trailer. As a bonus, FlexVolt batteries actually step down and run at 20 volts when attached to lower-power tools.
Besides the heavy-hitting FlexVolt, DeWalt is still running strong with their tried and true 20-volt MAX platform. This lithium-ion system of slider batteries is compact, rugged, and made for jobs needing moderate power.
How Do I Know Which Battery I Need?
With all these batteries for you to choose from, it might be a little confusing to know which you need for your tool. Worse yet, you especially don’t want to buy a battery only to find it doesn’t even fit in your tool. Since the two power platforms bear a striking resemblance, be certain you are adding the correct size to your cart before clicking on “Place Order”.
How Do I Know Which Batteries I Need?
DeWalt has three primary voltages for their cordless tools: 20 volts, 60 volts, and 120 volts. They are all marked with the battery size they require on the tool. 20-volt tools can use 20v MAX batteries OR 60v MAX batteries. 60 and 120-volt tools can only use 60v MAX batteries.
What Do FlexVolt Batteries Fit?
FlexVolt batteries are compatible with all DeWalt 60 and 20-volt DeWalt tools. A few exceptions exist that we’ll touch on below.
What Do DeWalt 20 Volt Batteries Fit?
Standard DeWalt 20 volt batteries are compatible with all 20-volt tools, as well as all 20-volt chargers. This means that once you join the DeWalt platform, you have access to over 100 products that all use the same battery technology.
DeWalt 20v MAX batteries can’t be used in FlexVolt 60v and 120v MAX tools, however. The lower voltage doesn’t provide enough juice for the high-demand motors.
What If I Put A 20-Volt Battery In A 60-Volt Tool?
FlexVolt receptacles have tabs that only allow 60v batteries
It will not fit. There are plastic tabs on all 60 and 120-volt tools that physically prevent using 20-volt batteries. FlexVolt batteries have special ports that allow their use.
What Are DeWalt XR Batteries?
DeWalt 20v MAX XR batteries are just like standard 20-volt batteries, but they last longer relative to their size. The XR stands for Extended Runtime, so you get extra life out of them before running out of juice.
Do These Batteries Work In Brushless Tools?
Yes, DeWalt batteries will work in all DeWalt tools of the correct voltage whether the tool is brushed or brushless. Brushless refers to the construction of the motor. Brushless tools will use the batteries more efficiently and therefore last longer per charger, however, than brushed tools.
What About DeWalt 12-Volt Tools?
DeWalt also produces a line of ultra-compact 12v MAX batteries and tools. These smaller batteries only fit on tools labeled as 12v MAX, and vice versa. 20v MAX and Flexvolt batteries are not only too powerful, but they are physically too large for the receptacles on these pint-sized devices.
Do 120v MAX Tools Have Their Own Batteries Too?
No. At the time of this writing, there is only one DeWalt cordless tool that uses 120 volts: the 12-Inch Cordless Miter Saw. While it harnesses 120v DC power, it achieves this by having two slots for 60v batteries running in series. As a substitute, DeWalt created an adaptor for the miter saw to swap out batteries for wall power since they have the same voltage.
Are There Exceptions To These Rules?
Yes. While most DeWalt batteries fit on all tools they are marked as compatible with, there are a few that don’t. Due to their size, FlexVolt packs don’t fit all smaller tools and adaptors. A few newer compact 20v MAX packs are slightly longer than others, and so also don’t fit all tools or chargers.

December 23, 2018 at 4:29 pmIf I use a 60 volt battery on usb charger does it last longer than the 20 volt
Acme Tools
December 26, 2018 at 8:06 amHi Joe, Thank you for your question. When you use a DeWalt FLEXVOLT battery the tool, or in this case the USB Power Pack, will determine if the battery will be ran in the 60V or 20V connection orientation. At this time DeWalt only offers a 20V USB Power Pack so the determining factor as to what battery will run longer on the power pack will be the Amp Hour rating of your battery. The battery with the higher 20V Amp Hour (Ah) rating will last longer in that specific unit.
Thank you,
Acme Tools
Phillip
January 28, 2019 at 7:33 amIt depends on the amp hr rating on the 20 volt battery your using. I have read that the 6 amp hr 20 volt battery has a longer run time than the 60volt flexvolt 6 amp hr battery when used in a 20 volt platform. But if you have a 60 volt 9amp hr or 12 amp hr . They will run longer than and battery you can get in the 20 volt Max line .

January 9, 2019 at 7:06 pmWill the 60 volt flex dewalt battery compatible with the 36 volt tools
Acme Tools
January 10, 2019 at 7:50 amHello, Thank you for your question. The DeWalt 60V FLEXVOLT battery is not compatible with the DeWalt 36V Tools, however, they will work with the DeWalt 20V MAX Tools.
Thank you,
Acme Tools
Mani
May 9, 2019 at 12:53 pmThere’s a way you can use the 20v battery on a flexvolt tool, by breaking off the tabs. My question is, if I use a 20v battery on a flexvolt tool, will either the battery or tool be damaged. Thx.
Acme Tools
May 9, 2019 at 3:54 pmHello, We do not recommend breaking the tabs off of the DeWalt 20V battery to try to operate a 60V tool. Just because you can break something to make it fit does not mean you should.
Thank you,
Acme Tools
Jeff
April 25, 2019 at 5:42 pmLooking to buy the Dewalt 20v chainsaw. I’m wondering what the biggest battery that will fit it? I have a 6ah flex volt in mind but i’d Like to have some reassurance there is no issues with a larger battery. Thanks
Acme Tools
April 26, 2019 at 8:18 amHi Jay, thank you for your question. At this time the largest battery we have tested in the DCCS620 Chainsaw is the 9.0Ah Flexvolt battery and it does fit. We have not tried the 12.0 battery yet and are planning on doing so soon. Once we do we will hopefully remember to update your question.
Thank you,

January 10, 2019 at 5:29 pmCan I use the 20V (non-XR) battery from my drill on the 20V XR hammer drill without it damaging it?
Acme Tools
January 11, 2019 at 8:07 amHi Phil, Thank you for your question. You can use the DeWalt 20V MAX non-XR battery on your 20V XR Hammer Drill, in fact, you can use any DeWalt 20V battery in any DeWalt 20V tool.
Thank you,
Acme Tools

June 24, 2019 at 1:36 amYou mentioned that we can use any 20 V DeWalt battery in any 20 V DeWalt tool. I have a DCGG571B grease and a quarter inch brushless impact driver. The four amp battery adds lot of weight. Will I simply have less run time but the same power in these tools if I use a 1.5 or two amp hour Battery?
Acme Tools
June 24, 2019 at 8:06 amHello, Thank you for your question. The run time will be less on a 1.5 or 2Ah battery in comparison to a 4.0Ah battery but you may also lose a little power. It is hard to say how much but the higher Ah batteries typically boost the performance of the tools.
Thank you,
Acme Tools

January 22, 2019 at 4:32 pmCan I charge 20v xr batteries on a regular 20v charger?
Acme Tools
January 23, 2019 at 7:55 amHi Brian, Thank you for your question. You can charge a DeWalt 20V MAX XR Battery on any DeWalt 20V MAX Charger. Depending on the charger you use it might take longer on one than another.
Thank you,
Acme Tools
Chris paul
March 31, 2019 at 3:46 pmMy question similar to Brian. I have dewalt standard 20v and 20v max xr. Both of these batteries came with there on chargers. I recently purchased online the flex volt lithium ion 20v/60v max. I notice one of those flex volt battery is not charging as well on my standard dewalt chargers. Do I need special charger for these batteries? Or I maybe have a defective battery? Thankyou
Acme Tools
March 31, 2019 at 5:04 pmHi Chris, Thank you for your question. The DeWalt 20V/60V FLEXVOLT batteries will charge on all DeWalt 20V chargers, there is not a specific charger for the FLEXVOLT batteries. It will seem that they are not charging as well because they have higher amp hour ratings than most standard 20V batteries and they just take longer to charge. If we think of amp hours like a fuel tank on a vehicle, the higher the amp hour the larger the tank. We get more run time but it takes longer to fill/charge.
Thank you,

January 24, 2019 at 5:23 pmHello and thanks for the very helpful article. Are the 60V/20V FlexVolt Batteries compatible with the Dewalt DCS331B 20V MAX Lithium-Ion Jigsaw? I understand that the voltage is compatible, but you say in the article that SOME cordless 20V MAX tools will not allow the FlexVolt Batteries to fit in them. You do not mention the DCS331B jigsaw, so it seems the FlexVolt 60V/20V batteries WILL WORK in that tool. Is that right? Thanks very much.
Acme Tools
January 25, 2019 at 8:11 amHello, Thank you for your question. The DeWalt FLEXVOLT 60V/20V batteries will work with the DCS331B Jigsaw. The compatibility issue comes into play when the battery is physically too large to fit into the tool. Some older lights and lasers have a compartment for the battery and because of the larger size of the FLEXVOLT batteries they do not fit.
Thank you,
Acme Tools
Kyle
February 3, 2019 at 7:12 amI was told not to use the 20v/60v flex volt battery on any tool that is not brushless or else it will burn the tool up. Is it true that those batteries only should be used on brushless tools?
Acme Tools
February 4, 2019 at 7:38 amHi Kyle, Thank you for your question. The DeWalt 20V/60V FLEXVOLT batteries can be used in any DeWalt 20V or 60V Tool no matter if it is brushless or not.
Thank you,
Acme Tools

February 19, 2019 at 1:48 pmI have a Dewalt DCD777C2 Drill an a DCF880 Impact Wrench the y came with the 20 volt battery 1h. was wondering what size 4h or 5h I can use with these tools. thank u
Acme Tools
February 20, 2019 at 8:00 amHello, Thank you for your question. You can use any DeWalt 20V MAX battery with your DCD777C2 and DCF880. The Ah rating on the battery could affect performance and runtime but it will not determine which tool it will work on (unless the battery is physically too large to fit into a designated area, as in some lights and lasers).
Thank you,
Acme Tools
Gary Adams
February 20, 2019 at 4:21 pmI just bought a dcs575 saw and it comes with a dcb200 3amp battery and standard charger from Ebay. Can you tell me if it will work with all my other 20v batteries? It says that it does work though
Acme Tools
February 25, 2019 at 7:37 amHi Gary, The DCB200 20V MAX battery you purchased on Ebay will work with your other 20V tools and chargers but the DeWalt DCS575 is a FLEXVOLT 60V Saw and requires the FLEXVOLT 60V/20V battery. It should never be sold by itself with a standard battery. To operate that tool you will need to have a FLEXVOLT 60V/20V MAX battery.
Thank you,
Acme Tools

March 15, 2019 at 3:39 amI wish to purchase a dewalt 20v 12 chainsaw, dwalt 60v trimmer, dewalt 60v recipirocating saw and extra batteries.
will the 60v trimmer, recip saw work on the 20v chainsaw
Will the 12in blade from the chainsaw work on the dewalt 60v chainsaw
Acme Tools
March 15, 2019 at 9:12 amHello, Thank you for your comment and question. The DeWalt FLEXVOLT batteries from the 60V Trimmer and 60V Recip Saw will work on the 20V Chainsaw, however, the non FLEXVOLT 20V batteries from the Chainsaw will not work on the 60V tools. The 12″ bar/chain from the 20V Chainsaw will not fit on the 60V 16″ Chainsaw. The chain that is used is a different pitch and gauge and will not fit on the sprocket of the 60V Saw.
Thank you,
Acme Tools

March 28, 2019 at 2:59 pmHello,
Will the 60 volt flexvolt batteries work with the Graco 17M363 Ultra paint sprayer which uses the Dewalt 20v Max Xr bettery?
Thank you!
Acme Tools
March 28, 2019 at 3:02 pmHi Bill, Thank you for your question. The DeWalt 20V/60V FLEXVOLT Batteries will work in the Graco sprayers that use the DeWalt 20V battery. These batteries are a little heavier than the standard 20V batteries but they have extended run times which is a real nice feature on the Graco sprayer.
Thanks,
Acme Tools

April 17, 2019 at 11:05 pmHi There,
I have a one year old flex volt 6.0 battery that shows a full charge on its pack, but when added to a tool…just allows the lights to flash. When I attempt to charge the battery, the light flashes twice and then stop flashing.
Any ideas???
Thanks,
Sonny
Acme Tools
April 18, 2019 at 7:36 amHi Sonny, Thanks for your question. It sounds like there is a bad cell in the battery. The DeWalt warranty will cover this defect because the battery is only a year old. We suggest contacting the retailer that you purchased it from or contact a local DeWalt Factory or Authorized Service Center and they will be able to assist you in exchanging the battery.
Thank you,
Acme Tools

April 24, 2019 at 11:50 pmHi, I was wondering if the 20v chainsaw will have enough room for the size of the 9.0 flexvolt battery.
Acme Tools
April 25, 2019 at 8:43 amHi Kevin, Thank you for your question. The DeWalt 9.0 Flexvolt battery will fit on the 20V DCCS620 Chainsaw. We physically tried it and it has a little room to spare.
Thank you,

Miriam
April 27, 2019 at 10:51 amHi. I won the jobsite radio at my companies Christmas party. But the battery was not included. I’m having trouble finding info on what actually fits. Of course I want the battery to be as big as possible. I’m also thinking of purchasing a weed whacker which comes with a 5ah battery. Will that one fit in the radio? I’m pretty sure the 6ah or 60v battaries won’t fit my radio?
I’m glad I found this site. It helped a lot!
Acme Tools
April 29, 2019 at 7:43 amHi Miriam. Thank you for your question and congratulations on winning the radio. If you could let us know the model number of the radio you won we will be able to see what battery you can run in it.
Thank you,
Acme Tools
Miriam
May 1, 2019 at 10:35 pmThanks for your quick reply😁 my radios model number is DCR025.
Acme Tools
May 2, 2019 at 3:08 pmHi Miriam. The DeWalt DCR025 will accept all 20V DeWalt batteries (as of today) so you are safe using the 5.0Ah battery that comes with the string trimmer. If you are looking for more run time it will also accept up to the 6.0Ah 20V/60V FLEXVOLT battery.
Thank you,

May 25, 2019 at 6:05 pmCan I charge craftsman 20v on Dewalt 20v charger?
Acme Tools
May 28, 2019 at 8:15 amHello, Thank you for your question. We are not currently handling the Craftsman 20V tools so we cannot test this but knowing the parent company Stanley Black & Decker we would guess no. At this time the other brands: DeWalt, Porter Cable, and Bostitch all have 20V tools and none of those are straight forward compatible. We would think they would do the same with Craftsman.
Thank you,

June 23, 2019 at 10:27 amRemain confused. I know the 40v batts are not compatible with 20 or 60, but still in the dark over 20 and 60 compatibility ESPECIALLY around charging. I’ve tried charging 60s on a couple of different 20v chargers I have, and the charge never goes beyond one bar. Can you list all the chargers compatible with 60 volt batteries just to be explicit?
Acme Tools
June 24, 2019 at 8:14 amHi Dan, Thanks for your question. All DeWalt 20V MAX chargers will charge the 60V FLEXVOLT batteries but depending on their amp output rating and the Ah rating of your battery the charge process could take several hours. We recommend the DCB118 because it is fan cooled and offers the highest amp output rating of the DeWalt chargers.
Thank you,
Acme Tools

Acme Tools
July 1, 2019 at 8:51 amHello, Thank you for your question. We do apologize for the service the DeWalt radio is giving you and we suggest that you contact a DeWalt Service Center or Authorized DeWalt Service Dealer for assistance. They will have a better idea of the issue and if the item is under the Factory warranty or not.

July 20, 2019 at 9:53 amI have a DC 970 Drill Driver that came with 18volt batteries. Can I use 20v or 20v max with this tool?
Acme Tools
July 22, 2019 at 8:06 amHi Mike, Thank you for your question. You can use your 20V DeWALT batteries in your 18V tools as long as you have the DCA1820adapter. The DC970 Drill driver uses the pod style batteries and the 20V batteries are a slide style. This adapter allows the batteries to fit on the tools.
Thank you,
Acme Tools

July 29, 2019 at 4:06 pmI have a standard 20v Dewalt Drill and a 20V XR 1/4″ Impact. My XR battery doesn’t power the impact any longer, and the standard 20v charger doesn’t even recognize when I plug the XR battery into it. It charges the standard batteries just fine. When I use the standard 20v batteries in my XR impact, it powers the impact, but it has less than half the torque, doesn’t even engage the impact stage, but in my cordless drill, it’ll burn a hole in my hand if I try to hold it back. Is it the Impact, or the incompatibility of the two products?
Acme Tools
August 2, 2019 at 7:45 amHello, Thank you for your question. To me it sounds like you have a defective battery but we suggest taking all 4 pieces (Impact, Drill, Battery, and Charger) into a DeWalt Factory Service Center or DeWalt Factory Authorized Service Center to have the cause identified and depending on the warranty status either corrected under warranty or estimated for repair.
Thank you,

Acme Tools
August 21, 2019 at 9:19 amHi Paul, Thank you for your question. the DCB106 charger is compatible with all DEWALT 20V batteries so yes it will work with the DCB205 battery.

September 18, 2019 at 6:40 pmI have a DCE100 blower it will not work with20V MAX DCB204 BATTERY, but does with DCB203 201 battery. How do you tell which 20V Max batteries work with what 20V MAX tools?
Acme Tools
September 19, 2019 at 8:30 amHi Thomas, Thank you for your question. First of all the DCB204 battery will work with the DCE100 blower. In actuality, all DEWALT 20V MAX batteries work with the DCE100 blower. The issue of a batter not fitting comes into play with a couple select tools, such as the DCS371P1, DCS371B, DCR015, DCA1820, and DWST08810. These tools have a closed battery compartment and some of the new larger batteries like the DCB606, DCB609, and DCB612 will not physically fit. The smaller batteries will fit just fine. If the compartment was larger the bigger batteries would slide on and work just fine.
Thank you,
Acme Tools

September 28, 2019 at 8:47 amI have an old 36volt multi tool kit with dead/dying batteries. Are they just paperweights now and do I need to look at newer systems? I can’t find that they are compatible with newer batteries.
Acme Tools
September 30, 2019 at 8:14 amHi Brandan, The DEWALT 36V lineup is not compatible with any other voltage line of their tools and the tools and batteries have been discontinued. There may be some older batteries on the internet but we would caution you when buying them. The 36V line up has been discontinued for some time now and any batteries that could be available for sale would be at least 5-7 years old.
Thank you,

Acme Tools
October 25, 2019 at 5:06 pmHi Audrey, Thank you for your question. The DCB115 is a charger but depending on the tools you have any DEWALT 20V MAX battery should work. Some of the popular batteries are the DCB203, DCB204, and DCB205.

Acme Tools
December 5, 2019 at 2:42 pmHello, Thank you for your question. You may run any DEWALT 20V MAX battery in the DCD996 and DCF887. They can be larger or smaller than the 4.0Ah battery included in the kit.
Thank you,
Acme Tools.

November 28, 2019 at 11:17 pmWill the 60v Flex Volt battery charge on a 20V Max charger? Will a 20V max Battery charge on the Flex Volt charger?
Acme Tools
November 29, 2019 at 7:14 amHello, Thank you for your question. When charging the FLEXVOLT batteries are in their 20V mode so they will be able to interact with all DEWALT 20V chargers. Some chargers will take longer than others to charge the battery but it will still charge them. There is not a specific charger for FLEXVOLT batteries so any charger you receive in a FLEXVOLT kit will work on all 20V batteries.
Thank you,
Acme Tools
