davidalan39 Posted November 9, 2017 Report Share Posted November 9, 2017 I have 2 18v Hitachi EBM1830 batteries that came with a 8 tool combo kit. Tried using my hammer drill, 1 battery works fine, the other says fully charged on the charger and when I use it with the drill, it runs about a minute before the drill quits. I can immediately place it back on the charger and it shows fully charged. Both batteries read 20.4v with a voltmeter. Bad battery? Quote Link to comment Share on other sites More sharing options...
DR99 Posted November 9, 2017 Report Share Posted November 9, 2017 It's weird they show the same voltage charged like that, but yea sounds like something wrong with the one pack if the other one works just fine. Quote Link to comment Share on other sites More sharing options...
