Lana 0 Posted January 13, 2020 Report Share Posted January 13, 2020 I bought a MILWAUKEE cordless hand drill, rechargeable battery, and I've had the battery pack on the charger but the lights are flashing green and red. The instruction book states faulty battery... So i took it back to home depot and got it replaced with same. Came home plugged it in, and the same thing; its flashing green and red! What the (#$&(&T%#!!!! Should I return this one also? Should I plug in over night? What drill should I purchase? Any recommendations? Quote Link to post Share on other sites
Biggie 371 Posted January 17, 2020 Report Share Posted January 17, 2020 It seems strange that both would have a bad battery, as it's not a common thing for a new battery to be bad. Even though its annoying I would return it and although it's a bad first experience I still wouldn't shy away from milwaukee as they do make good tools and batteries.

Don Monfils 41 Posted January 17, 2020 Report Share Posted January 17, 2020 Could the charger be defective? Do you know anyone close by that has Milwaukee cordless tools that would let you put the battery in their charger? I have 13 batteries and 6 chargers, I have never had this problem.

HiltiWpg 740 Posted January 17, 2020 Report Share Posted January 17, 2020 It's a crapshoot, I have had 2 bad batteries and one bad charger (brand new). Best thing to do is take it right to a Milwaukee service Depot. They can test them onsite. Sent from my Pixel 4 XL using Tapatalk Quote Link to post Share on other sites
Dan Doody 4 Posted January 29, 2020 Report Share Posted January 29, 2020 I had the same problem and called Milwaukee tech support. He said there is a protective coating on the terminals and you have to "slam" them in several times to get a good connection the first time. then you should be fine. 4 Quote Link to post Share on other sites
jgayman 0 Posted February 5, 2020 Report Share Posted February 5, 2020 I had a similar problem when I bought my M18 grease gun. It came with a battery and charger but since I already had a charger from a previous Milwaukee purchase I didn't bother to unpack the new charger. Anyway, when I placed the 1.5AH battery into my existing charger it just flashed Red/Green. I unpacked the new charger and inserted the battery and it started charging just fine. Now that it is charged it works fine on both my Milwaukee chargers. Weird, eh? Quote Link to post Share on other sites
CrustyOldSailor 1 Posted March 31, 2020 Report Share Posted March 31, 2020 Hats off to DAN DOODY for his post. New M18 battery inserted into new charger, RED/GREEN FLASHING LIGHTS. I did the INSTALL/REMOVE, INSTALL/REMOVE procedure several times to clean the contacts on battery and charger and I am GOOD TO GO!! DAN DOODY, you saved me a trip back to Home Depot, where some of the employees are currently not social distancing properly. I went in today to get the drill had the model on my phone, the guy reached out to hold my phone and reflexes kicked in. No harm, no foul, but come on, situational awareness much?? Thanks again for this forum and for Dan Doody's epic solution to my problem. 1 Quote Link to post Share on other sites

Thanks again for this forum and for Dan Doody's epic solution to my problem. I followed the same advice and still getting the green red alternating. Frustrating. It can flash like that all it wants but I refuse to get into the Xmas spirit! It's the end of May after all. So I unplugged the charger and let it sit for 20 minutes. Plugged it back in, put a battery in and solid red light! Back in business. 1 Quote Link to post Share on other sites

Kishore 1 Posted July 27, 2020 Report Share Posted July 27, 2020 I had same problem of flashing lights on my new battery . I tried the jump start by joining with another charged 4 Ah battery for few minutes and it got warm . Then cleaned the terminals meant to connect with charger and then charged it . Problem solved . 1 Quote Link to post Share on other sites
Geo501 1 Posted September 10, 2020 Report Share Posted September 10, 2020 I had the dreaded flashing red/green light dilemma on a new battery and charger. I had initially plugged into an anti power surge type strip. After numerous unplugging and battery inserts, I plugged directly into an out let and it worked just fine. Must have something to do with the circuitry in the power source. 1 Quote Link to post Share on other sites
Wkndwrnchr 1 Posted October 24, 2020 Report Share Posted October 24, 2020 Dan you're a life saver! I needed my my new impact wrench for a job tomorrow but I was super pissed when I got the red/green flashing. The charger and wrench are both brand new. Gave the battery one hard smack down and it clicked into place properly and started charging. 1 Quote Link to post Share on other sites

Cermantrout 1 Posted November 19, 2020 Report Share Posted November 19, 2020 I tried to fix mine by using a battery charger and putting the mode to charge... I then put the negative contact on the positive then tapping the negative on the battery 16 times arcing it out every time and it worked great. The battery is like brand new 1 Quote Link to post Share on other sites

DIYDude 1 Posted December 9, 2020 Report Share Posted December 9, 2020 Cleaned terminals with rubbing alcohol or was it vodka? Either way works great now. 1 Quote Link to post Share on other sites
BMiller 1 Posted January 3 Report Share Posted January 3 With all due respect to the other authors and their experiences, this charging unit is a piece of garbage. No one should have to fix a new $200 product by repeatedly "slamming" new batteries into a charging base (which, by the way, did not work for me). I will be returning my second Milwaukee M12 Fuel 2 Tool Combo Kit (2598-22) this week. I opened the first kit a week ago and the charging unit kept flashing red/green with both batteries. The two batteries worked with the drill and the impact driver out of the box, so I know they were not completely defective. After returning to a different Home Depot store after Christmas 2020 for an exchange, the same problem occurred with the second product and charger. The drill and driver appear to be nicely made, but I will never know now. Having worked in engineering companies my entire career, this is the product of poor electrical/electronic engineering design coupled with lousy supply chain practices. I've owned many tools from many manufactures over the years, but I will not likely purchase Milwaukee tools again. This has left me with a VERY poor consumer experience. A third mask-wearing trip to Home Deport during a COVID cycle is just what I need; I thought I had left the travails of 2020 behind in the rear view mirror, but that is not apparently the case. 1 Quote Link to post Share on other sites
Brianssss 0 Posted January 8 Report Share Posted January 8 I had same issue new battery would only flash green and red. So I took the 4 screws out bottom disassembled battery completely and used a car battery charger with small clamps and connected battery charger to small prongs on the milwaukee neg. And pos. Terminal after disassembling Milwaukee battery charged with car battery for 1 minute put it back together... charges fine now on Milwaukee charger and works great....

BrazeGod 0 Posted January 15 Report Share Posted January 15 Brianssss, what kind of car battery charger did you use? Or could you break down all things you used like what small clamps did you use? Thank you very much Quote Link to post Share on other sites
