How do you get new batteries to take a charge when they dont want to?

Usually one of the cells in the battery pack is out of sync with the rest of the cells. If one cell goes dead, the little computer built into the battery pack cannot figure out what to do, so it does nothing. Same thing can be in the reverse, one stays charged while the others are dead. Somewhere in this thread (I think) is a youtube vid showing how to disassemble, test and charge individual cells. Might be your problem.

Make sure it is a real milwaukee battery and not a chinkaneese knockoff. The chinese ones cannot handle being frozen and are useless afterward. The milwaukee ones are more tolerant of low temperatures. I tried a couple import batteries. Worked pretty good that summer, but one freeze event and they bridked. My real milwaukees have survived multiple winters.

I've jumpered the terminals of a charged battery to the matching terminals of one that wont charge and got the dead one kickstarted twice now. DON'T short any of the jumpers together.

One of the dead ones was in a recycle bin who knows how old it was, and has charged a couple times since.

These were delivered today. That air compressor/ 2 battery deal.

Got one to charge by trying a different charger. The other is being stubborn
 
If you can’t get it to charge just contact them and they will send you a new one, should take less than 5 minutes from my experience.

just in case you need one more person to say it. if a new battery doesn't work, send it in. even if you get to work... there is a reason its not now and batteries don't magically heal, you might get it to charge but its damaged. if one I have stops reading full bars, it gets sent in.

I honestly don't know the process, but the wife says its easy. shes returned allot of them.

It is easy, just fill out the stuff on the e-service side, have your model number and serial numbers handy, they give you a prepaid shipping label to print and use, special instructions for batteries, box and ship. They use to send out special boxes and bags for batteries that you had to wait for but I haven't seen that in awhile.
 
I put the 12ah Forge in my 2767 impact. It did some weird starts. Maybe something was sensing? I thought something was messed up, then it spun the lug nut as easily as expected. I don't remember it doing that with 5ah.

i've had issues like that, but they where always the trigger problems, not battery.
