IT's a battery
As power tool batteries go, the Bosch 18v offering is a good, solid performer. I can't say it's not worth the money - this battery gives good long service for its size. Bosch, as they say in the South, is "very proud of this battery." It's a shade pricey. But it's a nice light unit, good when you don't need hours and hours of power, or when you're working overhead. It's a very desirable battery - it would just be more desirable if it was a tad more affordable.

Light,slim,and a built in battery power sensor!
My son is a professional contractor.He said he buys Bosch and he wouldn't recommend any other brand because all the other brands don't have the battery life the Bosch has.

I got two of these with a combo kit last year. I really appreciate the fuel gauge - better than guessing where I'm at. One battery stopped charging after about 8 months. I contacted Bosch online and they quickly sent out a new battery.

I have at least 5 tools that use this battery. I purchased extra batteries to have an extra for each tool. They recharge fast and hold their power. I have switched all my battery operated tools to bosch...

nice battery
Nice smaller battery, good to grab for smaller jobs or intermittent use where the 4 Amp hr battery is unnecessary . Built in battery gauge works well. Good addition to my Bosch cordless tools.

excellent power & run time
This battery came with the drill/driver I purchased a month ago.  Far superior to any
other brands I have used.
