Makita BL4080H & BL4040F High Power Batteries: Extended Runtime Technology For Demanding XGT Applications

There is nothing quite as soul-crushing as being completely dead in the water on a massive job site because your battery could not handle the heat. You're completely dialed in, making aggressive cuts through engineered lumber or driving massive structural screws, and suddenly your tool just gives up and starts blinking at you. You're actively losing money every single second you stand around waiting for a hot battery to cool down on a charger. Makita just solved that problem with their newest power blocks. If you're tired of babying your cordless gear, it is time to seriously upgrade your loadout.

We are not just talking about minor improvements here. The entire XGT platform is built to discover the impossible on the job site. Hit play on the video below to see exactly how these high-capacity powerhouses are engineered to outpower, outsmart, and outlast the rest.

The engineers over at Makita just dropped the BL4080H 8.0Ah and the BL4040F 4.0Ah, and these things are absolute units. Both Makita XGT power tool batteries deliver an insane 35% more power than the previous generation. But raw power means absolutely nothing if the battery melts down under pressure. That is exactly why they engineered these packs to run up to 32% cooler while maintaining peak performance under continuous, heavy loads. The massive 8.0Ah version utilizes revolutionary tabless cell technology to maximize power output, while the 4.0Ah version delivers that massive output in a footprint that is 34% more compact than a standard 5.0Ah pack.

You drop your tools. We all drop our tools. Makita knows this, so they armored these batteries with an impact-resistant outer case and a shock-absorbing inner liner designed to withstand harsh, unpredictable environments. Add rigid rails for a rock-solid connection in high-vibration applications, and advanced digital communication to protect against overloading, and you have a battery that refuses to quit. Best of all, the massive 8.0Ah beast hits a full charge in just 76 minutes, and the compact 4.0Ah is ready to rip in a mind-blowing 45 minutes.

Stop wasting daylight waiting on inferior batteries. Upgrade your fleet today and experience the relentless power of the XGT platform before your next major project kicks off.

Is my Makita battery compatible with all Makita battery-powered products?

Makita batteries are compatible within each respective battery platform. 40V max XGT batteries are fully compatible with XGT products (including 80V (40V max X2) XGT products powered by two 40V max XGT batteries). The XGT System includes 40V max 2.5Ah, 4.0Ah, 5.0Ah, and 8.0Ah batteries.

What is the warranty on batteries and chargers?

Every Makita Lithium-Ion Tool, Battery, and Charger is warranted to be free of defects from workmanship and materials for the period of THREE YEARS from the date of original purchase.

Can I overcharge a battery?

No, Makita chargers are designed not to overcharge a Lithium-Ion battery. For example, the Makita Rapid Optimum Charger (DC18RC) communicates with Makita 18V Lithium-Ion batteries to detect their charge level. Once the battery is fully charged, the charger enters maintenance mode and actively monitors the battery's charge level to keep it fully charged.

Do you have to condition a brand-new Makita Lithium-Ion battery before using it?

No. Makita recommends simply charging a brand-new battery to a full charge before using it.
