I got these Tenergy Centura batts for the D-cell Maglite in our truck. These LSD batts are great over the long-run, for a flashlight that gets used only occasionally, hopefully.

I wasn't sure of the capacity at first but after a few uses it runs forever!

Very happy with their performance. Their performance has been as advertised.

I've purchased quite a few of these over the past two years from Battery Junction, and also the Tenergy charger ( a couple dozen), plus the same brand/type for AA, AAA, C, and 9V. They are truly low self discharge.

I did have two of the D cells leak on me in the charger when brand new, Battery Junction replaced them right away. None of the other batteries have ever shown any issues. I highly recommend them.

I used to use alkaline batteries in devices that were on standby. The NiMH were mostly for devices seeing regular use, whether I used them daily or for potential use during rolling blackouts. Then I saw NiMH batteries--these--that could be charged ahead of time.

Needless to say, I bought a bunch of them. I charged them up soon after, and I now know that, in the event of a blackout, I will be able to use them in emergency devices (flashlights and lanterns). I also know that these are good for more than one blackout. If we get a blackout, and I use these batteries, when the lights come back I simply stuff them in chargers (which I bought at Battery Junction--far superior to anything I can get at big box stores) and wait a few hours for them to recharge. Then they are good for the next blackout.

This assessment applies for all sizes of Tenergy low self-discharge batteries. I use them in AA devices (including the very fine Fenix and Nitecore lights sold here), and I got a bunch of AAA in LSD NiMH (of the same brand). That way, one charge and I am ready to pop them in my headlight and go, even if the blackout doesn\'t come until a thunderstorm in the summer of 2013. Annual top-charging is better than charging them in a panic a day or 2 before a windstorm.

One word: These are slightly lower in capacity than the regular Tenergy NiMH, which I still use in devices that receive daily use. You sacrifice about 20% of the capacity to get low self discharge. Also, I do have Christmas lights that absolutely require alkaline (or NiZn) batteries to work properly. These facts aside, I have the peace of mind that, should we get storm blackouts or a major energy crisis and rolling blackouts, I can simply use these fine batteries and still power my portable CD player and my fine lanterns.
