Are all AA rechargeable batteries Mah rates reliable?

Asked by manuel_alarcon (238 points ) May 16th, 2009

I found the other day a couple of rechargeable batteries i used years ago, they were like 700Mah. Recently i bought sony 2500Mah !! batteries for my camera. In january, i added to my stock some Camelion 2700Mah AA batts. but now, i began to see some chinese or japanese batteries, ranging from 3600Mah(Silverpoint) to even 4600Mah (Kayson). I wonder if these specifications are reliable… maybe they do and really last more than a 2500Mah batt, or simply not or be really a pain in the ass… did anyone try these brands? any recomendations?

They will be close as far as Mah goes. Where they will not be reliable is in shelf life.

Some will just last longer then others. Their charge dropping off faster also.

That might not be a big deal for a phone or a camera.

I fly RC aircraft. That battery loosing its charge quickly could cause some real problems real fast.
