Seems to be a general issue right. I've had 4 motor heads and 8 batteries with the same issue. I've replaced all batteries, Milwaukee EU hasn't given any proper feedback there. Last year I sent back one of the trimmer heads and there I got back from the repair shop that Milwaukee "has some issues with this tool and the chain saw too". I'm about to send back the two motor heads now for repair to Milwaukee. Have had contact with 3 suppliers, only one had other customers sending in the grass trimmer for repair for the same issue. The other suppliers didn't have any customers coming back. From two of them I'm awaiting them hearing back from Milwaukee EU to see if this issue has been solved to begin with. To be continued. Thank God for 3 years warrenty here But if the motor heads come back and still cause the issue, I'll return all motor heads and attachments instead. A pricy tool to just have laying around and not being useful.

Thanks for the reply. I have received back 3 of the batteries repaired from my dealer, they also said I should stop using the tool that causes this issue. I'm about to send back one of the string trimmer motor units to my dealer for repair, but I assume they'll do a lousy switch of the unit and no real fix. It's not promising that you got the exact same issues with a repaired/replaced unit. I've also had contact with Milwaukee EU directly and they only hid behind "this tool is developed for the High Output batteries, try those", even though that info I cannot find anywhere on their website/manual etc. On the Milwaukee EU website they even sell a package of the string trimmer + 5Ah (non high output) battery, so that don't make any sense. In the manual they have a "recomended battery" section which states the normal + high output batteries. I've send that info back to Milwaukee, but they haven't replied for a week yet. Let's see what happens. At least everything is going to the service center asap.

I have two quick-loc trimmers and both of them cause this issue with my M18 5Ah batteries. Out of the 10 batteries I have managed to melt 4 of them... :/ Returned 3 to my local dealer yesterday for investigation and repair/exchange. Today I used the tool with a brand new 5Ah battery. I used it for 5 minutes on slow speed, checked the contacts and they were OK. I left it rest for 30+ minutes and then continued for another 10/15 minutes until the battery was empty. When I checked the battery after it was emptied I noticed once again that the most right (negative) terminal was melted... that's number 4 dead. The battery nor the tool was even hot, at best warm to the touch. I have send a message to both the companies where I had bought the trimmers and also to the email address of Milwaukee EU. This is getting out of control. I will not use the trimmers until this issue is solved. Perhaps it can mean no Milwaukee trimmers, that would be a shame since they work amazingly quiet and have good performance. Did any of you find a solution or heared back from your dealers?
