Having had some appliances ruined by leaking alkali batteries, I've now become a complete convert to rechargeables. My previous experiences with other rechargeable batteries was that they could be more trouble than they're worth, but these Eneloops have changed my mind. They recharge quickly, run for as long as many disposables, hold a charge for years at a time, and there have been no reports of them leaking corrosive material if left in an appliance unused.
If you're confused about the different types of Eneloop available, I'd recommend a visit to the Wikipedia Eneloop entry (en.wikipedia.org/wiki/Eneloop). These HR-3UTGBs are the 3rd generation Eneloops launched in October 2011. They can be recharged up to 1800 times (compared to 1500 for the previous generation) and hold 90% of their charge if unused for a year (compared to 85% for the last generation).
I'd also recommend getting a good third-party charger (I use the AccuPower IQ328) as the Sanyo model that's sometimes sold with these Eneloops has a number of disadvantages: you have to charge the batteries in pairs, it has no progress display, no choice of charging rates, and no discharge function - which has been useful to refresh some of my older batteries which were losing their ability to hold a charge.
The blue cases that these batteries come with hold four AAs or five AAAs each and clip shut securely. Very handy for carrying a spare set in your camera bag.

Eneloop are my top choice when it comes to batteries. They offer great performance, reliability and charge retention through the years.
There are various generations of eneloop batteries with Sanyo producing the first 3 generations. In 2013 Sanyo was acquired by Panasonic and the 4th generation was introduced. Other variants were also introduced by Panasonic.
These HR-3UTGB Eneloop batteries are the 3rd and last (standard eneloop) generation produced by Sanyo. They are top quality NiMH offering:
- 1900 to 2000mAh (Minimum - Typical)
- Astounding 1800 charge cycles
- Awesome charge retention through the years: 90% after 1 year / 80% after 3 years / 70% after 5 years
- Batteries are pre charged by the factory, (albeit to approx 75%) so they can be used straight away
- Virtually leak proof, even if left in a device
The handy sturdy battery case can store 4 AA or 5 AAA batteries
Tip: In order to achieve maximum longevity, use a quality smart charger designed for NiMH batteries. In contrast to dumb chargers, these will monitor the voltage of each individual battery and avoid under / overcharging.
These batteries will last for years, and given the price they should definitely be on your short list!

This is my 5th order for Eneloops from Amazon as literally everything needing an AA or AAA battery in my house is now powered by them. I have well over 70 with my current order, and have never had a single problem with them.
Compared to ANY other rechargeable cell type there is simply NO comparison if you want extended charge retention as they far exceed any other technology on the market (even Li-Ion without the problems of that technology). The only way in which other cells can match or exceed is in short duration very high current applications where the higher capacities and ultimate higher discharge current of other manufacturers NiMH cells comes into play.
Treat them well, with a decent charger, and never try a 1 hour charge if you want them to last! I bought the first set with a specific Sanyo charger included, but have since bought two Maha MH-C9000's from Amazon (also sold as Everex - same product) which I cannot recommend highly enough. They're twice the price of the cheapest LCD charger, but well worth it in my opinion as they offer discharge/cycle/condition modes as well, and also allow each individual cell position to be programmed independently and display terminal voltage, charge rate, time, and total charge to each cell.
I always charge the AA Eneloops at 500mA and the AAA's at 200mA giving about a 5 hour charge if the cells are empty and have never had a single problem.
The cells keep getting better and better with the HR-3UTGBs, and I just wish they offered a PP3 version!

Have the first version of these batteries I bought about 4 years ago and they are still going strong. These are the latest version, HR-3UTGB, and are supposed to last longer than the previous ones. I use them for everything.... bluetooth keyboards, Magic mouse, magic trackpad, Camera flash, iPhone recharging module etc. Once recharged, I leave them in a plastic tray in a drawer till needed and they hold charge so well that they work perfectly even after a few months in the drawer or left in the camera flash.

These are a high quality battery and I have been using them for years. Unlike cheap rechargeable batteries they don't stop working after a couple of dozen recharges, they keep on going.
But they have a little trick up their sleeves also! Unlike other rechargeable batteries they don't lose their charge as much when you don't use them. Now this may not seem like much but the next time you use a device that you haven't used for 6 months and you find that the batteries need recharging, then you will start to understand why Eneloops are so good. They will hold plenty of charge for a year or more!
They seem to be like good alkaline batteries that can be recharged. Compared to Alkalines the only downside is that the voltage is a little lower but I think that manufacturers are designing their kit to work with the lower voltage of NiMh rechargeables.
This product has the benefit of a plastic storage box to boot!

A while back I decided to upgrade my battery drawer with a load of NiMH batteries - so happily picked up the highest mAh ones I could find at a decent price.
Problem was that after a dutifully charged them, when I actually pull them out, most of the charge has gone.
This isn't a problem for those that either follow a regular battery charging regime, or simply use them regularly - but I was merely looking to replace packs of alkalines.
For me, these batteries ideal - their selling point is that they hold their charge for a very long time. Buy them, chuck them in the drawer (they come charged) and simply pretend they're that value pack of alkaline - except when they run out, you can re-charge them.

Simply the best rechargeable battery's I've used......Great Quality! and will hold there charge if stored or not used for long periods.

These are the best rechargeable batteries I have ever used and I've tried loads of different brands. I was very sceptical about paying as much for them but, it really is worth it, if you want your rechargeables to hold their charge for long periods of not being used and also make sure you use a decent charger to get the best out of them.

Love this batteries, self discharge so low you can use them in almost anything... Only thing I don't bother with is clocks and TV remotes. Wireless keyboards etc. are fine. Have over 50 of these in various capacities, only cell I know that stands the high drain applications well .. I.E. flash cameras etc.

Superb batteries, they feel significantly heavier than normal batteries (especially cheap alkalines which are a fraction of the weight). They hold charge well and coupled with an intelligent charger (google Voltcraft) they give consistent charge levels. I'd never buy cheap rechargeables again.
