honkmeister

A little update from me also: I sent my melted battery to a Milwaukee authorized service shop and I got a new battery in return, no questions or comments. So I called them to see if this was known as a common problem, but to their knowledge it wasn't. Anyway, I've continued to use the trimmer, but only on low speed from now, and veeeery, very carefully. I've noticed that my other 5 Ah battery (from the same batch as the melted one) also runs hot att the terminals, the plastic has become a little bit deformed on this one also. However, the new battery I got does not seem to run hot?! Coincidence? Or has there been any changes in the design? I guess time will tell...

Hi, same thing happened to me yesterday. Brand new grass trimmer / powerhead (M18 FOPHLTKIT) and two brand new 5 Ah batteries. The first battery ran out of power after only a few minutes, and so did the second one. And that second one melted. The load was really not very heavy, and since they ran out of power quickly it wasn't running for a very long time either. I also had some kind of grey powder on the battery. Could it be some residue from arcing? I will contact the supplier here in Sweden, but the feeling in my gut is that they will say "This has never happened before". So I'm very interested in knowing how it was handled by Milwaukee for the rest of you, was it covered by the warranty? Thanks in advance!
