rebuilding a milwaukee m18 battery pack

[Mighty Mouse]

I have one that doesn't hold a charge anymore- has anyone rebuilt them? Where can/should I buy the replacement batteries for it?

[Mighty Mouse]

why? The case is screwed together, I haven't taken it apart yet, but I don't see why one couldn't just replace the batteries? I did it with a few Nicd milwaukee batteries, but never a li-ion battery

Batteries plus.

No need for any further explaination.

This article on instructables covers swapping the cells in a craftsman unit, including a source for the new cells. You could probably adapt the information to your situation.

unless I'm missing something, I don't see any 18v Li-ion batteries offered in their Milwaukee lineup

M18 and V18 have lithium ion batteries.

You should still have warranty left on them? I didnt think the m18 series has been out long enough to be out of warranty yet? Thought it was 5yr warranty?

while i haven't opened up a LiIon pack yet, i know there is at least some circuitry inside controlling charge behavior as well as overheat shutoff. point being, swapping out a bad cell may not make that pack whole again...

ahm

I talked to some techs at Batteries Plus & they said they don't rebuild Lith Ion batteries because the circuitry inside makes it too problematical. However, if a person has enough time to do it, it may be possible.

Sounds like more trouble than it's worth, thanks for the info guys, looks like I'll just buy another one.

You still didn't answer the question.

The Milwaukee Warranty Every MILWAUKEE power tool is tested before leaving the factory and is warranted to be free from defects in material and workmanship. MILWAUKEE will repair or replace (at MILWAUKEE's discretion), without charge, any tool (including battery chargers) which examination proves to be defective in material or workmanship from five (5) years after the date of purchase. Return the tool and a copy of the purchase receipt or other proof of purchase to a MILWAUKEE factory Service/Sales Support Branch location or MILWAUKEE Authorized Service Station, freight prepaid and insured. This warranty does not cover damage from repairs made or attempted by other than MILWAUKEE authorized personnel, abuse, normal wear and tear, lack of maintenance, or accidents.

The warranty period for V28, M12 and M18 Li-Ion Battery Packs is two (2) years from the date of purchase. XC M18 Battery packs carry a (5) year warranty.

Are you outside of warranty? Have compact or fat battery?

Right, but I bought them from a neighbor who moved down to FL. Warranty only applies to the one who purchased the tools/batteries.
