Lenmar Ready-2-Go R2GAA4 1.2V 2150mAh Rechargeable NiMH

Product Review

The ready-to-go convenience of alkaline batteries plus the economy and high-performance of Nickel-Metal Hydride rechargeable, the R2G batteries are ready when you are - even straight out of the package. R2G batteries hold their charge up to 4X longer than standard NiMH rechargeable batteries. Perfect for both low and high-drain devices. And they work with any NiMH charger. Lenmar R2G vs. Standard NiMH Rechargeable Nickel-Metal Hydride batteries hit the market with a warm reception. Finally there were batteries they would last longer in high drain devices and you could recharge it over and over – no more going through 100s of batteries. There was, however one flaw in the design: NiMH batteries could not hold their charge for a long period of time. Out the package, the batteries needed to be charged and if you left them in your drawer for over a month, you would need to recharge them again before use. For this reason, many people still kept alkaline batteries around for emergencies and just plain convenience. Lenmar R2G batteries combine the best of both worlds! They are “Ready to Go” out of the package and have a shelf life of over 1 year. This means once you charge them up, they can sit in your drawer or device for a year and not lose their charge. Now anytime you need batteries, you will be Ready-2-Go. Included in the Box: Convenient carry Case

Slightly exaggerated capacity rating - Not as good as Sanyo eneloop, August 13, 2010

NLee the Engineer (Nashua, NH) - See all my reviews

According to the product description of Lenmar Ready-2-Go R2GAA4 Rechargeable NiMH AA Battery, the Lenmar R2G cell is even better than the well-known SANYO eneloop, because:

1. It is "pre-charged and ready to use" just like eneloop,
2. It has a higher capacity of "2150mAh" (instead of just 2000mAh for eneloop), and
3. It "holds charge at 85% for a year" just like eneloop.

I purchased a set of those Lenmar R2G cells a few months ago, and analyzed them using my old La Crosse BC-900. Here are my findings:...Read more

Descent rechargeable batteries, I like the Sanyo Eneloop batteries. But these are up there as well and for the price, definitely worth.

Plastic casing melted off all 4 R2G Lenmar rechargeable batteries, September 10, 2011

Ed Hendrickson Jr. "ace" (Ames) - See all my reviews

This review is from: Lenmar Ready-2-Go R2GAA4 1.2V 2150mAh Rechargeable NiMH AA Battery (4 -Pack) (Electronics)

I bought these from Fry's the beginning of July 2011. They worked fine until I took a trip and borrowed my Fathers rechargeable charger. The charger says on the back it can recharge Nickel-Metal Hydride batteries. All 4 batteries got very hot and the plastic casings melted off all 4 of them and ruined the charger which I had to throw away. The batteries only charge about 10% now. I only charged the batteries maybe 3 times before that. So it cost me a set of new batteries + ruined charger.

I'm not 100% sure if it was the charger or the batteries, but I have been using that charger for years on all other name brands of rechargeable batteries and it has been charging the other brands just fine. So I think it was the batteries.
