Jump Start That Battery: A Way to Recover Ni-MH Batteries that are Fully Discharged

Ever leave rechargeable batteries in something a little too longer after they've stopped working only to find that your battery charger refuses to charge it? Well, I certainly have! Here is a little trick to get them working again. You mileage may vary, but here a few things to be aware of: Only attempt with Ni-MH and LSD Ni-MH (i.e. Eneloop, etc..) batteries; do not attempt with any other battery chemistry (Ni-CD, Li-Ion, Li-Polymer, LiFePO4, etc..). It is really important to have an amp clamp or a DMM that can measure at least 10A, in order to measure the current to help you better determine if it is working or not, and not to damaging both batteries. Current should spike and then settle down quickly as the "jumped" battery's voltage increases. If the battery immediately gets warm to the touch during attempt to jump it, stop and wait for the battery to cool. If it consistently gets warm, see the next item. If no current flows or current remains high (more than 2-3 Amps) after 15 seconds, then the battery is damaged, and will not accept a charge.
