Rated 5 out of 5 by from Great for working on small overhead projects. Great for working on small overhead projects, much lighter than my heavy duty XC 5.0 battery. The price is a little steep but I have some physical issues with my elbows and I was able to get more done with the decreased weight.

Rated 5 out of 5 by from Perfect compact size for the Milwaukee Heated Jacket I would recommend buying two of these batteries with the M18 Adapter for use with the M12 Milwaukee Heated Jacket in extreme cold conditions. They will last just over 4 hours each with the jacket on high at around 0 degrees Fahrenheit. If it is warmer, you can expect them to last even longer. They have the perfect power-to-size/weight ratio for anyone who needs to get the most out of this amazing product.

I use this battery when I'm on ladders and it makes a lighter tool. When I have to constantly run a tool I use the 5.0 so I'm not constantly changing the batteries.

Rated 1 out of 5 by from Garbage Bought a cordless drill with 2 of these batteries. After returning the first because one of the battieries was bad from the start I went back and got another one. Now after 3 months and 1 use another one of the batteries has failed. Just spend the extra money and buy Makita. Don't waste your time and money with these pieces of junk.
