Hey folks
I need some help from the community. My 12V Li Milwaukee driver is in trouble because the batteries won’t charge. Here’s my problem, either both batteries died at the same time (and by died, I mean the charger says they are defective) or the charger died. I’m not a heavy user so I have my suspicisions about both batteries dying together (very romantic though). Also, if I get close to the charger when it’s plugged in but NOT charging anything, i.e. no battery in the charger, it makes a quiet hissing noise. None of my other brands of chargers do that. So to avoid replacing either battery or charger without knowing which one is defective, I wonder if anyone out there has the same type of 12V Li charger (pic attached) and can listen to it for me and let me if yours talks to you too.
In return I’ll happily listen to my other tools for you!
Thanks in advance for any help.

Hi, Bruce, I was curious to check out that link, but it generates a "Page not found." Can you help?
Problem over...sort of
In case anyone runs into this problem:
Per DanH's suggestion over at Breaktime, I took one of the batteries to the local BigBox (where I had purchased it) and the guy at the rental counter let me try my battery in his charger. Worked fine! Ah-ha I said, Great. I took the battery home and just for fun, plugged it into my charger and it charged just fine. Arrrgh. So I put the other battery in and showed a fault. Placed the good battery in the charger and now, it too shows a fault.
I give up. I'm sending the charger and batteries back to Milwaukee (I just dug up the receipt and it's still under warranty).

Have the same problem with my Milwaukee 18v drill/driver. Batteries will not hold a charge. No problems with the other cordless items using conventional batteries. About ready to send it to the landfill and recycle the batteries. Beginning to think this Li-ion thing is not what it is cracked up to be.
I have the same concern with my 18V Milwaukee drill. I recently responded to a poster on the NorthCarolinawoodworker site who had the same problem as we have. I have finally decided to trash the drill, recycle the batteries, and stick with Ni-Cad drills from now on. Have had a DeWalt 14.4 volt impact driver for longer than I had the Milwaukee and it has not even showed a hiccup during this time frame. Kind of ticks me off since this is not an inexpensive tool, I am not a full time contractor using the drill 5 days a week, 8 hours a day. Lesson learned.
Millwaukee 12V Li-ION Battery Fault
Was very pleased at first with the power of this for the size, but I doubt I have 5 hours use & get a trouble code red - green blinking for a faulty battery, BOTH BATTERIES. Just my 2 cents! keithO
milwaukee 12v batteries charging problem
Both of my 12v Milwaukee Lithium batteries "died" at the same time. I bought a new charger (thinking that the strange hissing noise in the charger was the problem). Turns out the new charger makes the same noise and still indicates that both batteries are faulty.
Clearly this is a manufacturing defect with the batteries. At $40 each this is outrageous that after only a few dozen times using the drill with these batteries that they should both screw up. I have written to Milwaukee but have not heard a reply.
If Milwaukee does make good on this I will let this forum know, but frankly I doubt they care about the consumer!
Any one find a solution or help on this Milwaukee Li-ion problem?
My batteries didn't last at all
litium packs
I recently aquired one of these so called dead packs from a fellow contractor and upon dissassembly discovered a small zener diode buried under a silicon compound to be at fault. unfortunately there are no markings on this diode to know exactly what to replace it with. all cells have checked out ok and will all take on and hold charge with no problems. I suspect this diode is in place to stop terminal arcing when connecting to charger. Any ideas as to the value of this zener to save me dragging out and dusting off the old books it's been a while since i had to work out this stuff.
