Pexy13 Posted December 9, 2017 Report Share Posted December 9, 2017 Greetings I have a problem with my drills batteries because they are old and don't hold charge any more like they used to (no torque and speed). The drill itself is in good shape so i was thinking about buying a new LiPo battery and replacing the connectors and stuff to make it work with my drill. The drill is Bosch GSR 12-2 PRO. Is this a good idea and would it work normally or is it more beneficial to buy a new drill? Thanks Quote Link to comment Share on other sites More sharing options...
rrich1 Posted December 10, 2017 Report Share Posted December 10, 2017 I would personally buy into a new lithium ion system. It will give more options for tools and be much safer than retrofitting tools. 2 Quote Link to comment Share on other sites More sharing options...
DR99 Posted December 10, 2017 Report Share Posted December 10, 2017 It can be done but its not recommended a lot of things could go wrong with that. I don't know if your in another country because in the USA you can get a cheap lion Ryobi pretty cheap or Harbor Freight. 1 Quote Link to comment Share on other sites More sharing options...
BMack37 Posted December 11, 2017 Report Share Posted December 11, 2017 You can do it but it's not terribly economic to do so unless you can get the battery for cheap. The cells should be welded to the tabs and that's not easy, you can't stick, MIG or TIG weld it (reliably without danger), it's an ultrasonic weld. With drill kits being around $100-$120 on sale, there's no real reason, in my opinion, to make your current tool backwards compatible. The new stuff probably won't last as long but replacement costs aren't a lot. Quote Link to comment Share on other sites More sharing options...
