A subject I have very little experience in - Replacement batteries (PA14; 14.4volt). One of my battery packs for Makita Drill has failed not bad after 15/16 years. I would like a new battery but since they are both pretty old will replace both - The double drill pack cost £79 15 years ago - new Makita batteries cost £50/55 x two !! seems expensive; has anybody experienced good/bad of the alternatives packs £15/25. Or do I wait for a deal and buy new drills !!
