Out of my fleet of 5 M18 9.0s, 4 might need to visit the Milwaukee warranty center soon beforethey start hitting the 5 year window with the first being bought somewhere in 2016. Milwaukee has been great to deal with overall on prior warranties. 9.0's seem to be the only batteries I have had issues with.
One over drained (completely my fault), one with a dead LED indicator (still seems to be functional, but painful not being able to tell its state of charge) and two that are now out of balance (three bars when fully charged). On the out of the balance ones should I crack open the cases and individually charge the out of balance cells or just cop out and send them in for warranty? Not sure how much I can extend their lives, but hate the fact that the warranty center might scrap perfectly decent battery packs if they hand me new ones. For these out of balance ones does anyone know if Milwaukee is replacing them with an equivalent 9.0, repairing them by individually charging the cells (which i can do) or replacing them with 8.0 HO's (ideally)?
