Only Recharge Battery that Competes with Panasonic Eneloop
"Due to EPA regulations pertaining to the hazardous materials involved, almost all of these batteries are made in China, Korea, or Japan. Their Quality increases in that order. A Tenergy made in China is a very good battery, A Korean battery is better. A genuine Panasonic Eneloop Japanese battery is nearly a rechargeable ordinary battery. Here in America, the only available battery that competes with Panasonic is the Tenergy. I've had Tenergy rechargeables in a TV / Blu-ray player remote that lasted an entire year without needing a recharge. How reliable are Tenergy Premiums? My IV Medication Infusion Pump comes with them. That's right, every day I bet my life on a pair of Tenergy Premium 'C' batteries to keep my IV medicine pump working. They never fail to charge. Get recharged every three days until they fail (about 6 months) before they won't hold a charge. Google MOOG/Curlin Infusion Pump. That machine EATS batteries for breakfast. A pair of C batteries lasts about 35 hours before they are sucked dry. My Pharmacy sends Tenergy Premium C batteries to me. I bet my life on them."

Made in China garbage
"Bought a bunch of these a few years ago for emergency lanterns. They've only been recharged a few times and almost half of them refuse to charge now."

Tenergy Centura LSD batts are great for emergency flashlights.
"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."

Nice 8000mAh capacity!
"I wasn't sure of the capacity at first but after a few uses it runs forever!"

Excellent Rechargeable D Battery
"Very happy with their performance. Their performance has been as advertised."

As advertised, very pleased
"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."

Great for ongoing emergencies
"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."
