They get lots of use.

I have 2x4amp 2x1.3amp and a 3amp. They all get used on different tools, and I'm surprised how long even the smallest last. I would recommend them to anyone.

Loads of power. Test lights handy to check remaining charge. Seems pretty robust. Register each battery with Bosch for up to 2 year warranty. All in all I am happy with the change over to Bosch 18v tools

Bosch battery review

I have used Bosch professional tools for a few years now and have to say one of the main reasons I have picked them are the 18v li-on battery's, they last a long time under great stress and daily use, these particular batteries show how much power is left by simply holding the on button at the back of the battery. I would always recomend these batteries. Never had any problems with then.

10/10 buy.
