If you can, buy the Ikea brand... they are excellent and for all purposes, as good as the Eneloop batteries.

I searched the Hog for recent posts about Eneloop batteries and didn’t find any. Since this technology seems to change often I wanted to ask about your recent experience with these batteries.

I tried NiMH batteries back in the late 90’s/early 2000s and they were awful. They would self discharge so fast that you could not charge up your stock and expect them to have a useful charge a few weeks later. I had the PowerX batteries and a Maya MHC9000 charger.

My questions are as follows:

1. Are all NiMH batteries today created equal so long as the mah ratings are the same?
2. If no to question 1, which brands work the best.
2. Will my old maha MHC9000 work on the newer batteries or do I need to replace it? I see they still make the model, but I don’t know if it was upgraded since the newer technology came out.

I’m currently using Eveready
LIon batteries and would like to find something more wallet friendly. Your input will be greatly appreciated.

No, all rechargeable batteries are not created equal. Many of the brands available are significantly over rated and inconsistent. Eneloops are typically under rated. I am sort of a fanatic with rechargeable batteries. I have over 150 AA and AAA batteries and a spreadsheet where I keep track of location/use, number of recharge/refresh cycles and recharge mAh and voltage. The most consistent brand is Eneloop. Most of my Eneloop batteries are Gen. 4 which are Low Self Discharge (LSD). I've had reasonably good success with Tenergy and EBL (both LSD) but they aren't as consistent as Eneloop. I've had Eneloops hold near full charge for 18 months.

Your current charger should work. I'm using OPUS chargers, BT-C2400 and BT-C3400. I also have a backup La Crosse BC-700 but it sometimes doesn't fully charge the batteries requiring a second discharge/charge cycle. I also track which charger I use for which battery.

I have dozens of AA and AAA Eneloops that I have had for many years. They are used and recharged very frequently for use in flash and LED light units that our volunteer team uses for archaeological site documentation. They are also used continuously in GPS units and small but powerful flashlights for local Search and Rescue teams. Most have been recharged well over 100 times. I have not had a single one fail. For the last year or so, I have also acquired the higher power Amazon Basic versions which I have been reliably informed are made by the same people as Eneloops. Again, not a single failure or disappointment.

I did have some powerex versions. They were good but there have been a couple of failures after many uses. Nothing else has come even close to the reliability.

I have used the same Maya charger for years and to the conditioning cycle on all the batteries have couple of months because of the high use. I got the newer version a couple of months ago and I like it even better for it automatically defaulting to low charge rate and providing a capacity value after conditioning. After large field outings with a large team and many cameras and lights I will frequently have both chargers working away on dozens of batteries.

Bottom line Eneloops and the higher power Amazon Basics are all we use now. Never a failure and either of the Maya chargers are fine. I also have a LitiKala 500 that only does 4 batteries at time, does provide a capacity value after conditioning and also works on our dozen or so LI batteries that are needed for some of our lights.

I just wanted to share my experience using an Everready rapid charger. It was not good. After charging several sets of NiMH batteries using the Everready rapid charger, my batteries were ruined. For all purposes, they no longer had any shelf life. After charging, they would self-discharge within a day. I will not use a rapid charger. I don't know it the Maha charger is considered a rapid charger.

I've had a Powerex charger for years... it's excellent. Many inexpensive chargers only charge the batteries to the capacity of the lowest battery and will eventally bring all your rechargeable batteries to this lowest value... maybe the Everready rapid charger does this. The Powerex does not do this and actually reconditions the batteries to the max charge they can accommodate.

Why not just order them online from Amazon.com? They sell various models and pack sizes at reasonable prices.

P.S. I've used these batteries for years. They work great and hold the charge really well. But a few of them eventually stopped working (couldn't recharge them any longer) for no apparent reason and in this case, all I could do was to dispose of them.

Amazon sells them very reasonably. I’ve used Eneloop for years for everything that uses batteries. They last a long time and hold their charge well in storage.

You can buy Eneloops from Amazon in whatever volume you want, AA and AAA both, for a very reasonable price. Be careful using some chargers because they charge too fast and will "cook" them shortening their life. Generally if it says "Fast Charge" you may consider staying away from it. The Panasonic charger that comes with the Eneloop "Kit" is a good one, though I usually use a LaCrosse that offers maintenance and restoration cycles, as well as a choice of charge rate, also offered on the PowerEx, which has the advantage of 8 at a time, for sale on Amazon. I have Eneloops, some the original Sanyo brand purchased by Panasonic, for many many years, and they work as well as they did when new. Never having to lug home big packs of batteries is a good thing, and I use them for everything from Camera's/flash to my toothbrush. Go with the Eneloops, you will not regret it.

I use the lower capacity Eneloops in AA for my speedlights. They outperform alkalines and hold their charge for a very long time. The speedlights cycle faster and last longer with them. Costco sometimes carries the kit with AA, AAA, C converters and a charger.

I haven’t seen them in the Costco stores near me for at least a couple of years.

Eneloop are good for long life cycle but generally only give ~2000 mha vs ~2800 mha for some others. Will depend on whether your devices are happy with only 2000 mha.

More amp-hour capacity is always welcome, but a couple of caveats: (a) it often comes at the expense of number of charge/discharge cycles, and (b) it’s easy to publish a spec, but real tests to a standard measurement method and user experience are more realistic.

I have multiple Eneloop batteries in various sizes. I've never had one fail. I use them is all different devices. I don't think you can go wrong with them.

I had no trouble locating them on Amazon.

Good luck.

I bought my first eneloops, AA and AAA more than 15 years ago when they were a bit expensive but worth every penny. Since then I use eneloops exclusively, there's never been a leaky battery problem or any problem when using either the higher powered black version or the standard white version. As for chargers I've relied solely on the chargers sold with the batteries.
Eneloops are reliable trustworthy elements of my photo kit.

But to all - what version Eneloop are you using? Amazon has a White version, a Black version labeled Eneloop Pro, and a new Red version. The description for the Pro version says can be recharged only 500 times, the White 2000 times and the "new" Red version 2100 times. I must believe the ampacity is also different, but just curious what version you all are using.

I've used the standard white version for years, but I've also purchased the same battery in different "special advertising edition" colors. I read somewhere that the black Pro version had a slightly larger diameter that fits the receptacles in most but not every device out there. The white Eneloops have been by far the best rechargeable batteries I've used, though none of my devices are high drain applications and I've not tried the Powerex batteries.
