Anyone hear of these batteries?

I really like the Eneloop batteries. They seem to be a great battery, although not real high mah, and they look classy too.

Sanyo also makes Eneloop chargers. They include a USB charger and a new solar charger.

I have a few of the Eneloop batteries. It’s a good concept but I have found that they don’t have the same capacity of regular NiMH batteries. I’ve also found that some of my gear did not work with the Eneloop batteries although it did with others. I don’t know if it was lower voltage or what.

For most backpacking applications I wouldn’t recommend these. Either use regular NiMH and charge them up right before the trip or use lithium. I think lithium has the highest power to weight ratio.

I’ve found the best reviews of NiMH batteries and chargers here at Steve’s Digicams. If you use a lot of batteries I’d highly recommend getting an advanced charger like the La Crosse BC900. It can actually rejuvenate older batteries and since each battery is on it’s own circuit you can charge 3 batteries (which is how many my headlamp uses).

Eneloop batteries are rechargeable and available in AA and AAA, with adapters for C and D applications (though for C and D use with adapters they will have a lot less power than regular C and D cells).

They are well suited for applications where you don't want to have to constantly charge your rechargeable batteries – say for an add-on camera flash that you'll be using from time to time, which might site in a gear back for a week to several weeks between uses. Or for backup or emergency batteries that you may charge only once every few months – eneloops will hold most of their charge for a year. We use them for emergency radios, emergency low power LED lanterns and power back up for devices like alarm clocks.

If you need a good, high quality high mAh NiMH battery, go with the Tenergy AAA and AA. These have a lot of power, but can drain a lot of their charge over several weeks or months. They'll do fine for a few days to a week trip if charged right beforehand. They can be used many hundreds of times.

A good charger that won't cook the batteries will greatly extend their use.

Wonder if they come in 9V and whether that can be used for smoke alarms? That's the one area where I am still using disposables…

their site says they can be used with other battery chargers. anyone have experience with this? I just got the energizer rechargeables (with 4 AA and 4 AAA) for Christmas, and the charge loss could certainly become an unpleasant surprise. It would be nice to not have to buy another charger.

I use Energizer rechargeables for both hiking and home use (to power my electric razor and toothbrush). For the latter, the batteries are good for just over one month per charge.

For multi-day or even a week-long hike, continuous discharge is simply a non-issue. You only need to make sure you have enough to power actual usage.

I have charged them in my La Crosse charger so they at least work with some chargers.

Again, I wouldn't recommend these if storage isn't your main concern, they have significantly lower battery life than regular NiMH batteries. Eneloop AA are 2100mAh and there are regular NiMH batteries available now up to 2900mAh.

When I'm traveling I love the compact, lightweight Energizer chargers like this one. Make sure you don't get one with any kind of power brick, those are heavy and the cords are annoying.

I have a bunch of AA and AAA ENELOOP batteries, and have been pleased with them. Granted, they don’t last quite as long as alkaline batteries, but they last long enough to be worthwhile (I can run my Garmin eTrex Vista for about 10 hours on a set of ENELOOPs).

I charge them with a MAHA MH-C9000 charger, which I *really* like. They are not cheap ($60 plus shipping), but …

1) It has four slots that can accept either AA or AAA
2) You can select a different function for each slot (CHARGE, DISCHARGE, CYCLE, REFRESH, BREAK-IN)
3) Both the charge rate and discharge rates are user configurable (and, again, can be different for each slot)
4) It has a big LCD display which shows the progress/status of each slot.

I got mine (and most of my batteries) at Thomas Distributing. Here is a link to the charger … Click here

hey all yeah i've been using eneloop batteries for about a year now and they do very well you can get a combo pack at costco 8 aa 4 aaa 2 adapter c 2 adapter d and the charger for 25.95 pretty good deal
