Re: Milwaukee M18 HD12.0 (12 amp hour battery pack) unbalanced failure charger refusi
Well I have one more M18 HD12.0 battery pack that I tested and of course it was way out of balance and the amp hour between were very uneven as well discharged battery group cells to roughly 3.1something
This battery pack is taking the longest to charge as well but I have all 4 fuel gauge lights on which is good sign this battery probably not the oldest one either so at least I think so because I bought two at same time and the other one much later on
But it weird that all three of them had the same exact issue so what this tell me is that the BMS protection board is not best one in the world but it does let you know that they are unbalanced when you can not get all four fuel gauge lights to light
I have several Ryobi battery packs that are doing the same exact thing only three out of the four LEDs light up which is probably the same exact issue but I need to make a jig for doing this type of testing
What is telling me is that as these batteries age they might also become unbalanced as well but I have bought new batteries to replace them and use the old ones in another application and I will regroup them when I do this for better preforms out of them
I have to wait a month or more for the BMS protection boards the tabbing and the plastic battery cell holders to arrive so I can put them together in the original battery enclosure for Milwaukee
And use the Chinese made enclosure for the batteries that have been regrouped for better preforms hopefully this will be the case
