NIMH Questions
1. What happens if I'm soldering a lead onto a NiMH battery and it gets pretty hot. Will it damage it permanantly? How will I know if it is damaged?
2. What is it safe voltage to discharge a NIMH down to?
3. What is C rating is it safe to charge a NIMH at?
4. I had to change the config of my battery setup and one of the batteries got pretty hot from soldering. I let the pack cool down and tried to hook it up to my charger. My charger didn't recognize that there was a pack the first few times and then it accepted it. For some reason when it started charging the voltage went up and peaked very fast, after adding like 70mah, when I tried to discharge it, it would bottom out after about 50-80mah. I did this several times and it kept doing the same thing. The last time I did it it has actually added close to 4000 mah to the pack, it's a 6 cell 4200. Do you think the pack is damaged? Whats the deal?
