Serious homeowners and trade professionals often step up to 18-volt batteries. You'll get the high torque or speed that your tools need to complete construction level projects with 18V models. Some tool models run on slightly more powerful 19.2-volt batteries. Since many of our single battery model usually power many different tools, you should coordinate the best battery choices with the highest-quality compatible tools.

As a homeowner, you might not have much call for 24V batteries, but if you plan to build your own home or you work in construction, these are ideal for long-running equipment. Once you get into the range of 36V batteries and higher, you're likely looking at outdoor equipment like cordless chainsaws.

Lithium-ion batteries provide superior performance to the old Ni-Cad or Ni-Mh batteries. They resist developing a "memory," so you don't have to run down the charge completely before you charge them again. Lithium-ion batteries are lightweight for comfortable working. Look for fade-free batteries that run at or near peak power for the duration of their charge, so you don't experience a loss in performance. Make sure to grab at least two batteries so you can charge one while you work with the other.

Power tool batteries offer exceptional versatility and are easy to use. You can reuse them many times for extra value and eco-friendly operation. Research which tool lines you want to buy, then purchase the appropriate cordless power tool batteries and a charger to power them.
