Rechargeable AA 4 Pack 2700mAh Batteries by Lenmar

My son's school science project this year was to test a set of rechargeable batteries. He conducted two tests on Duracell, Sony, Energizer and Lenmar: 1. Long term storage test where the batteries were fully charged and stored for two weeks before measuring the voltage. 2. Capacity test where randomly selected two batteries were fully charged and put on a regular flashlight until a complete discharge happened. The first test was inconclusive. He repeated the capacity test mutiple times and the clear winner was the Energizer NH15BP-4 and the Duracell came in second. BTW, the manufacture's claim on the overall capacity was not even close to the measured capacity. This battery should have outlasted other batteries by at least 15 - 30%. Instead, it came in third on the average.I would have give it a four star rating if it was not for its 2700 mAH claim. For the money, it was pretty good.

I am using these batteries in a digital camera, and have been very pleased with the performance. I have been using these batteries for several months, they seem to maintain their charge very well. Recently shot 100+ pictures at a wedding and vacation and the batteries still have a useful charge level.

These batteries DON'T provide power for long.

Good batteries, hold a great charge for a flash unit. Only reason for a 4/5 is one battery out of 12 took about 4 charge cycles to function correctly.

I do almost ALL of my shopping here on Amazon. The UPS guy is actually at my house at least once a week. That said, I don't think I've ever written a review here. This will be the first and it's not a good one. That should tell you how strongly I feel about this. These batteries are awful. They do not hold their charge at all. I use them in the remotes for my TV's, and I've had to charge them several times in 2 weeks. A regular battery off the racks lasts well over a year (probably longer), and yet I have had to charge these several times already. Complete waste of money for the time and electricity these use. I'd rather stock up on regular batteries.

I just recently switched to these batteries because they have 2700 mAh! As I started to write this review, I noticed that they are having a BIG SALE on these -- about 1/2 price! So, I ordered several more packages.I see that I'm not the only one who prefers these -- the reviews are good and my experience with them are good.I highly recommend this product.

It cheaper , and it comes almost 12 Hr for our leappad ..which i feel it same when compared to other popular brands . Value for money .

These batteries are just a hair thicker than standard AA batteries. I inserted them into my camera's flash unit and had to pry them out. My Duracell and Sony batteries fit just fine.
