By the way, the cells at Walmart, AA 1800 mAmp must be the Energizer rechargeables. I don't think that they can stand up to a fast charge like we prefer to use on everything.
You are corret which cells they are. No, I don't fast charge them. (who needs to?... you can get 4 hours flight time without recharge.) And I do have a charger that peak detects for NiMh....
There are some 2100 mah fast chargeable NiMh's available at Wal-Mart... I may be looking at my next repacement batteries.

I will have to get some and test a bit for reliability before trusting a model to them.... (I never blindly trust new tech.)
