M18 Red Lith XC5.0 I jad the same problem. Tried this and it worked. I only left the batteries connected for about 30 seconds. Thanks for the fix! Saved me from dealing with Milwaukee.
Milwaukee customer service is absolutely 💯 HORRIBLE. Either you pay to ship it in or you go back to the store you bought it from. A BRAND new battery! I will try this, thanks.
@@rvz77 I hate to hear that, especially with how much they are in love with their products! Their prices on that stuff are getting insane! I guess I'll be looking more into Harbor Freight stuff in the future, I hear it is getting pretty good, and hell, it's all made overseas anyway!
Just started working at a heavy diesel repair shop. I noticed many chargers and batteries out of commission. Deap pockets just buy new batteries and chargers apparently. Thank you for the information.
Worked on mine - I have a variable power supply - put in 18V 1A max, and in 20 seconds the voltage went up to 11V, with one blinking light on the battery pushbutton LED display. Plugged into the charger, and it worked great
I didn’t have the wire so I use a coat hanger and it actually work! Thanks for the video. I had 2 brand new batteries out a set do the same thing. I’m glad could get them working again! 👍👍👍
Wow this shit worked!!!! I had nothing fancy like you. So I used a coax cable stripped it to the wire made two small cables for positive and negative waiting 8 minutes and boom!!! Thank you
I have a 1.5 AH M18. Used it once in an LED lamp. Perhaps I left the lamp on, perhaps not, but the battery was dead. Tried to charge it in the Milwaukee charger. Two chargers the same symptom, flashing red and green. I have an electronics lab bench supply. Connected the supply to the battery as in the video. Turned the current limit all the way down, and cranked the voltage up to maybe 12V, then cranked the current up to 1A. As the battery charged, the current went down, so I gradually turned up the voltage in steps until I got to 18V. At 18 volts, I let it charge until the current started dropping below 1A at 18V. Took only about 5 minutes. Disconnected the supply and plugged the battery into the charger. Now is charging OK. Up to 2 bars. Just completed charge.
I tried this probably six months ago. Not sure what I did wrong because it killed my 8ah battery. I now have a dead 12ah, 8ah, and two 6ah batteries that are all paperweights. Seeing all the positive responses makes me think I did something wrong but I did a similar process to your video. Used 12 gauge wire and the wire got extremely hot, extremely quick.
I heard this trick of an adding a small charge manually also works for enabling charging of a really dead automobile battery with one of those portable lithium battery jump starters they won’t operate with a battery that is too far gone. However, doing this trick to fool a smart charger into charging a dead or defective battery can lead to overheating, swelling, and possibly fire/explosion. One of the cells in series in the pack may have gone bad so forcibly charging it could have undesirable consequences. The safety features are put there for a reason.
I bought a 2 pc combo drill and driver pack from home depot that came with a 3rd battery....after trying the insert and remove 20 times (only guidance I got from milwaukee) it still didn't work....I'm going to try this with 1 of my other batteries and see if my 3rd battery just is too dead to charge, I sure hope it works.
Thank you, this sort of worked. My dead battery (which the indicator showed zero bar) when place in the charger, flashed red/green. Then I tied your trick with a good battery (neg to Neg / Pos to Pos) and when I put the bad battery in the charger it went direct to Green. So it did make a difference. I left it on the charger for about an hour or more, it still stayed on green. On the battery itself, the indicator only showed one bar and was flashing red. Another hour, charger is still green and the battery indicator is still showing a single bar, flashing red. Any suggestions or thoughts?
@@AccuracySpeaks um...I have no experience with stuff like this. I'm a 61 year old cat-lady. What should I be careful of? BTW...THANKS SO MUCH FOR RESPONDING!!!😘
@@calonstanni putting too much voltage or amperage into batteries and such can cause some nasty things to occur. If you do things incorrectly, you can have a battery explode or possibly a fire, and you don't want that to occur! I'd ask a friend that is handy for some advice. As far as responding, you're certainly welcome! I'm sorry I can't tell you anything with certainty. Check out a comment below from a viewer that stated that they used a battery tender.
I'm sure there is if you know what you're doing. I do not know a great deal about electronics, so I don't want to tell you something that can ruin your gear or hurt yourself. I'd imagine if you have a battery with the same or similar voltage you could probably excite the cells enough to trick the charger. As far as I know, all you're doing here is tickling the cells with enough charge to show at least a little charge on the battery so the charger will recognize it is a battery. If you go to throwing too much amperage or voltage to an electronic device, I do know you have the potential for bad things to occur like explosions, fires, and possibly injury, so be careful! If you've never had a battery blow up on you, I'll tell you this, you don't want to! I witnessed a truck battery explode one day many years ago on my Dad's old 70's C-10 Chevrolet. If you would have been working under the hood when that damn thing blew, it would have killed you without a doubt, it was about like a grenade going off, it was a hell of an explosion, one I hope to never witness again!
I'm not an electrical engineer, so I cannot positively answer this, however, I'd say it's possible. If it were me, I'd be careful and use similar voltages... I have an automotive charger with this so-called "smart" technology that I have likely replaced several perfectly good batteries because the charger wouldn't charge the battery! I feel this is no accident, they want to sell batteries!
I have a brand new M12/M18 charger, model 48-59-1812, that seems to charger the batteries OK, but the area above the port for the M18 gets so hot that you can smell melting plastic. Has anyone else experienced this? If so, was there a way to correct it other than sending it to Milwaukee for evaluation?
If it's brand new it would for sure be under warranty. If it's getting that hot, I'd recommend not using it and contacting them, I'm sure they'd gladly get you another charger out to you, you certainly don't want to burn your house down! To answer your question, I have never experienced the situation you are.
Battery Issue. The Fix is Place a Jumper from bad battery to a good charged battery. Pos + to Pos + and Neg - to Neg- terminals wait for about 15 minuets for battery to equalize. problem solved. both batteries are ready for work or charge to full
Hello, i have a Milwaukee charger that flashes red, i tried jumping but it didn’t work. Red flashing means outside charging temperature, i left it over night and that didn’t work. It's an expensive 12amp and to say im pissed is an understatement. Whats the issue can anyone reading this shed some light if battery can be fixed or is it toast?????
I made mine with about a foot of speaker wire and crimped on 4 spade connectors. If you don't have any wire laying around, Radio Shack, if they even still exist, would have some wire, or a car stereo shop would probably have some. They may even throw you a jumper together if they were cool if you asked them...
