I have a Princeton Tec headlamp, the Quad model, which has the low battery sensor on it. I started getting a conflicting problem where the lamp wouldn't change brightness levels, but the low battery indicator never came on either. The failure to change problem was mentioned in the owners manual as low battery condition. Princeton Tec never explained the confusing one-but-not-the-other condition, but switching to the NiNM batteries seemed to make it function OK. PT actually recommended going to the NiNM batteries over the Heavy Duty generic WalMart brand AA batteries I was using.

The other Princeton Tec Corona I have has no battery level indicator, and I never have had the brightness changing problem. It just gets dimmer and dimmer until I change the batteries. I have a feeling the difference is due to the electronics that each uses. I do know that those single chip LED controllers with current/voltage regulation sometimes display the problems of the Quad.

And Tom, my wife uses 2300 mah NiNM batteries in her A95 and it seems like forever before I get to quit smiling for a battery change break. We use the EveryReady brand. A great camera. I'd like to find a cheap A620 model for hiking.

I have a feeling a lot of the charged life of rechargeable batteries is dependent on the charger. Some probably quit charging sooner than others, resulting in less mAh.

Hope that helps
