The Lenmar R2GAA4 AA Ready-2-Go 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 batteries 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.
Absolutely the best batteries for the money. I now use nothing but Lenmars in my photog kit. I have nearly 60 rechargeable Lenmars (mostly AA, some AAA and 12 C) and NOT ONE DUD among them - some are more than 2 years old with no sign of crapping out. They're longer lasting per charge and recharge relatively quickly. The only caveat, use an updated charger designed for batteries up to 2700 mAh. I charge mine on a charger that predates 2700 mAh and the 2700s will get so hot, if left unattended, the skins will melt/split. No harm, I peel them off and use them anyway. I do not care for the case that comes with some 4-packs. But to others users, it's probably handy. Personally, I prefer the Storacell Slim Line Battery Caddies for better protection and one handed swaps. Nor do I bother keeping bought sets together to keep track of aging as recommended by another user. To each their own, but that's a hassle for which I don't have time. Instead, when a flash or other gear indicate low battery, I'll test the batteries after the shoot and see if one has less power than the other, then mark it with a Sharpie as a possible dud. To be clear, however, no Lenmars of mine are possible duds. My rechargeable Energizer NiMh batteries, however ... geez ... 1 in 7 are total duds. But I digress :-) In short, I scrapped all my Energizer rechargeables to reinvest in Lenmars and don't regret it one bit. In fact, the only reason I'm on this site today is to buy more Lenmar 2700 AA packs.
These batteries are solid and work great in my Canon 580EXII. I carry a few set of them with me when I shoot weddings and they work awesome. They charge in about 90 minutes (with 90 min charger) and allow the flash to cycle quickly for continuous shooting.
Worked as advertised. I'd buy them again without hesitation.
I like Lenmar chargers and batteries. They work best in general use including electronic flashes.
The packaging and color has changed but the batteries are the same as in GREAT
don't hesitate to buy these
Out performed my expectaions. Longest lasting rechargeable batteries I have ever purchased. Worded so well that I will be purchaseing more for uses other than photography.
I love these batteries because they are long lasting and I can get almost 2000 shots per charge on my Canon S5 IS for a time lapse when hooked up to my computer via USB and having the LCD turned off :)
5 batteries took a charge, 5 are no good. The 5 that took a charge lasted for 3 flashes on a canon speed light. I bought 10 Energizer batteries and have had no problems. Will never buy Lenmar batteries again!
These batteries have the highest capacity that I have ever had. Digital Cameras consume a lot of batteries and with 2700mAH capacity, they are just right for them.
