    • Great for high powered tools.
Style: 12.0Ah Lithium-Ion
This battery is amazing. It feels like it lasts forever and is my go to battery for my higher powered tools like the grinder and circular saw. It is heavy and bulky but it's worth it for the high power tools compared to swapping the smaller ones nonstop.

    • Battery leakage
Style: 8.0Ah Lithium-Ion
There was black gunk running out of the battery and was inside the package as well. The battery had the same issue the batteries that came with the Flex tools. I have flex tools and no battery that will function. I have since changed tool brands that seem to know how to make a battery. The tools were great, the battery had a lot to be desired. ... show more
