Ok - my Xtar WP2 came today. It has 2 charging rates 500 mA and 1000 mA. My Pila is fixed at 600 mA.
My batts are AW IMR 18350, 18450, and 18650's. Is it safe to charge them at the 1000 mA rate?
I have read that it is safe and much faster. I also remember reading long ago that a slower charge was better for your batteries in the long run. Unless you're in a big hurry, I'd charge at a slower mA. Just my .02.
Jewels, I did some research on the AW IMR batts. Looks like charging at 1Amp w/ the Xtar is well within specs for the following batts. I haven't run across a slower charger is better, but I'll be watching out for that too. Even the lower rated batts are good up to 1.5A and 1A w/ the Xtar is just 2/3's of it's max. To this 'dummy' that seems well within the batts acceptable charging rate.

Now me still wonders if the
not-AW IMR flat top batts I got from the battery co-op have similar specs w/ respect to max. charging rate?
