Status: offline 		I believe it is a good idea to discharge your batt packs completely before recharging. I was wondering if anybody has made a homemade discharger and how.

Or,

Hook the battery up to a small light bulb.

Without some method of terminating the discharge you run the risk of reversing 1 or more cells which can permanently damage the pack. There is no reason to discharge a pack other than to check capacity occasionally.

Status: offline 		I would like to refer this to a higher power, but until OZ has spoken, I wouldn't discharge/cycle them after each use. Just isn't necessary in my opinion. Although batteries are by far one of the most important links to our success, we tend to make them more complicated than necessary at times_Bob

Absolutely agreed, I make it a habit to go 9-12 slow charges before discharging, or 6-8 fast charges. I've read over on ezonemag that too much discharging is as bad as no discharging for NiCDs, and NiMH don't ever need to be discharged (at least that's what the manufacturers say).
