I have a very good charger and run my batteries on a very strict schedule of top up charges even if I don't use them. The charger is very intelligent and won't overcharge them. By my math I'd have to charge them if I let them sit and they self-discharged anyhow. Most NiMH are good for about 500 FULL charges so this doesn't really reduce their overall life...especially since I switched to all LED lights.

The next time one or two won't recharge, I'm definitely going to get the low self-discharge type...but I'll hold out a while and get them wholesale and not retail...way way cheaper from places like Thomas Distributing.

Oh. And speaking of chargers I put together a 'power kit' a while back to cater to my gadget fetish. An Energizer Duo USB charger, a Ziplinq X2 USB power adapter, Some custom USB charge cables, an Energizer AA cell phone charger (modified to output to a USB port), and a 12V all weather folding solar panel. I can charge my phone, AAs or AAAs off of a lighter socket (12v or 24v), from a wall outlet, or from the rays of the sun. Sounds like time to post about another one of my kits
