Causes of failure for M18s
Their are quite a few causes of the dreaded flashing red and green lights. Most commonly it is a low series bank of cells. A m18 has 5 series banks that are independent, the chargers charge off of pack voltage and can not fit a low bank of cells. After some time of the banks of cells continuing to get lower it damages the cells and the cells around them, eventually leading it the cells getting to low before the next charge. and the charger will not function. Depending on the levels of usage, if you get 3+ years out of a pack your doing pretty good. Its best not to charge right after taking it right off a tool, Give it time to rest and cool. Also the standard charger is always the best, it creates less heat increasing the lifespan.
