Ryobi 40 Volt Battery - Reflash Fix

I'm hearing that the 2.4 Ah and 5 Ah batteries have an internal memory chip counter with a software bug. There is an int variable that should be a bigint. The battery stops working because of an overflow bug. Ryobi has found the bug and can reflash the battery. If the battery has sat too long the cells might be physically damaged and they can't reflash it so don't wait.
