I have anywhere from 6-10 projects going at once and often have messy working areas. Sometimes there are victims. The latest victim was a Dewalt 5AH XR Battery that took a dip into 2 quarts of used diesel oil. Time slowed as it careened end over end and was completely immersed. I did manage to fish it out quickly, set it outside for 2 days to drip, brake cleaned it. The battery meter still lit and shows 1 bar. Opened to see the carnage and the batteries, circuit board and bits were lightly covered. It lived a hard life chopping cedar, and will live again after recycling. RIP.
