Energizer NH15BP-2 AA Nickel Rechargeable Batteries (2-Pack)

For me they work great, I use them for my xbox controller with headphones connected to it, philips sonicare toothbrush (which to my surprise needs two AA batteries) and so far so good. They seem to last a lot longer than the regular batteries. Also reusing them saves our dying planet lets not forget :)

After going through my first 4-pack of alkaline batteries in my digital camera in only 1 day, I immediately looked into rechargables.I hadn't purchased any rechargables in a while, back when only NI-CADs were the only option. I was often a victim of the memory effect, which NI-MH completely eliminates.My camera has both an LCD display and a viewfinder, and the batteries will usually last about 2 or 3 days of picture taking unless I use the LCD monitor, which will reduce the longevity to about a day and a half.If you transfer your pictures directly from your camera instead of a card reader, your battery power will suffer a great deal.Overall, I'm satisfied with these batteries, but with today's higher-drain cameras, I'm sure there are other batteries that will hold a stronger and longer charge.

Bought these batteries to use with the Kodak battery charger (which ships with 4 AA batteries.) Plan was to use them for my digital camera.They work, but unlike the batteries that ship with the Kodak (which are 1600 mAH-rated), these batteries are rated at only 1200 mAH. mAH means milli-amp hours and is a measure of the amount of power the battery can store and deliver before needing to be recharged.So, they deliver only 75% of the life of the higher-rated batteries. My digital cam responds to this with a half-battery indicator, even when all 4 batteries are at full charge.

Just began using. Happy with purchase.

Batteries may be fine, but when we opened the envelope we found tiny worms inside! Disgusting. In addition I called the company 2 times to report it and they never responded. Never using them again.

Well I was looking for some rechargeable batteries from Amazon, and I ran across their own make. It was kinda expensive for shipping because I only had a $10 gift card, so I found these by Mel Pierce Camera. (Sorry Mel Pierce Camera, but I don't use a camera.) I had needed them for my Controller so I could stop buying all these store brand batteries that didn't last. These work great. =)

NiMH rechargeable batteries are a step above the standard NiCads that gave rechargeables their bad rep. NiMHs usually provide more stable and slightly higher voltage (though still below alkaline levels) for extended periods of time. They have no "memory" problem, so you don't have to worry about completely discharging them, and depending on the situation, they may perform either better or slightly worse than alkalines.For instance, I always use NiMH batteries in my CD player. They last about 90% as long as alkalines and, of course, are reusable. A quick one-hour charge will get the same pair going again.Where NiMHs really shine, though, is in momentary high-drain devices such as digital cameras and camera flashes. In a recent report, Consumer Reports had to rescale its battery ratings because NiMHs perform so well. In one digital camera that I use, alkalines will last for one flash-card of pictures; NiMHs last for over 3.While the Energizer (and recently Rayovac) brands are quite inexpensive, they only last about 85% as long as the Radio Shack brand. Cost versus run life is the only consideration here, and these batteries are just great for CD or tape players.Note: You will need a NiMH-specific charger to charge these batteries.Overall recommendation: If you use even a moderate number of batteries frequently or listen to music on a portable player, NiMHs are a worthy investment.

I buy rechargeable batteries since we have a million things in our home that need batteries. They do stop holding their charge after awhile but it's worth the extra money because for the price, they're still cheaper than non-rechargables.
