XTAR AA Battery 1.5V AA Lithium ion Batteries 3300mWh High Capacity, Quick Charge Double A Rechargeable Batteries 4 Packs with Battery Case(4 * 1.5V 3300mWh Batteries)

Using with my Razer Naga, works well. I switch it out weekly so I don't risk running out of battery, but these charge fast so either I'm not using much and these last a long time or they just charge faster than others I've used. Either way, great batteries.

Have been great for flashlight, camera, GPS, and electric razor applications.

I've been using these in a trail camera for several weeks now. They appear to be about 2300mah when drawing about 200 miliamps. Decent capacity. So far, I think they're excellent.

I bought the batteries hoping I could charge them in my NITECORE, but it did not work, so I got the official 8-cell charger later. The batteries work, but the continuous voltage output to exhaustion could leave you with a suddenly dead flashlight, a stalled radio control boat out in a lake, or an inop portable radio. Regular Li-ion batteries will tail off quickly, but not instantly, so these XTAR are not that much worse. But you won't have a few seconds to find and grab your backup in the dark.
