Bosch 1600Z00038 18V 4.0Ah Li-Ion Coolpack Battery is rated 4.7 out of 5 by 11.
Rated 2 out of 5 by from Lasts about 1/2 a day After 2 years these batteries last about 1/2 a day on drilling joists etc. Start the day with a full charge, by about lunch time the indicator lights on the battery are flashing indicating low charge. For the price I would expect a little bit more performance. Always like a Bosch tool due to swapping batteries to another ie jig or a circular. Not sure now whether to go to Matka !!

Rated 5 out of 5 by from Well Priced Battery Bosch battery - Excellent price and is interchangeable with all my other Bosch cordless tools

Rated 5 out of 5 by from Unbelivable run time! Bosch claim 65% longer run time than their 3ah battery and i can belive it! this battery is putting in the same amout of screws as 3 of my Hitachi 3ah batteries. they charge in 45 mins, the battery life indicator is reaaly handy. Once it goes down to 1 they still just keep going then it will flash one led and still put in quite a few roofing bolts before finally giving up. If the price can be held at what they are they are the cheapest 4ah battery on the market which makes the tools a very attractive buy.
