This seems to be among the highest capacity AA batteries out there. Are there any other NiMh AA's that have higher capacities?

There are higher output non-rechargeable batteries. These wouldn't power a device I have which will run for about 8 hours with Energizer Ultimate Lithium. I'm groused I can't seem to find a rechargeable that'll power the device.

You won't find a better combination of capacity & quality than these Eneloop Pro 4th generation batteries...until the 5th generation comes out! ;)

There's PowerEx but there's been some problems with those even though many people probably are fine with them they are not really low Self Discharge batteries. I highly recommend the high capacity Eneloops but you could try the PowerEx's but i'd read the reviews first to see if you really want to get them.

Not any more.. PowerGenix had a Nickel-Zinc (NiZn) AA Battery that was but it still did not compare to the eneloop Pro / XX line. Remember that the eneloop Pro only has a 500 Cycle Life compared to the eneloop with 2100 Cycles.. But the Pro is a Higher Capacity Battery designed for devices like High Power Camera Flash's, RC Toys, High Draw Lab Equipment, Wireless Mics Etc.

It comes with 4 AA batteries, NOT 4 AAA batteries. The reviews indicate that they are more than adequate for filling a 2GB xd memory card.(300 plus pics?) It accepts alkaline as well as nimh batteries. You can get extra AA batteries anywhere. That's the beauty of it.

No way, even if the D cell you are comparing it to is really just a sub-C cell in a D body. A true D-cell rechargeable has about 5 times the energy storage of a AA of the same technology. And forget about trying to use a AA alkaline to replace a D. Even the voltage difference is practically moot. Take a typical old flashlight, for instance. After a short while, the alkaline drops below 1.2v under load, while the NiMH maintains its voltage until it's nearly empty, meaning (for many applications) the rechargeable far outperforms the alkaline. And that's just on one charge.

Any rechargeable AA will work. The ones with the higher mAh ratings will likely hold a charge longer. I've used different brands without noticing much difference. I would just avoid the cheapest, unknown brands.

I too use Tenergy Low Self Discharge Ni-MH D cell batteries in mine. They are expensive but work great. Eneloop AA batteries work with adapters, but they don't last very long.

A Nickel-Metal Hydride cell (NiMH) is a specific type of rechargeable cell. The specification describes its' physical and chemical properties. The AA size cell is the same physical size in any type or brand. Chemically, a NiMH cell contains the same chemical makeup although different cells could be physically different inside. Different brands of AA NiMH cells can be used together. However, I would hesitate to intermix those with different mAH (milli Ampere Hour) ratings due to the difference in discharge rates and recharging rates. If all the AA cells have the same Specs. (That is, New, NiMH, 1800 mah, for example) they should perform as expected. (Be aware that the Specs. on some cells are overstated.) Don't mix new ones with old ones. Don't mix NiMH with NiCD (Nickel -Cadmium), alkaline cells or any other type. Also, you didn't ask but don't mix different size cells of any type whether series or parallel connected. When it's "all said and done", there IS a difference in brands. Some are just better than others - probably due to greater care in the purity of chemicals and manufacturing. All these things considered, I believe you can safely use Eneloop NiMH AA's with Amazon Basics NiMH AA's of the same mah rating without any problem. I wouldn't hesitate. I hope this is helpful.

This battery is larger due to the extra capacity. I'm sure it is a little heavier. This hasn't been an issue for me.

The enclosed literature does specifically say to use only NiMH. Mine shipped with a Sanyo Eneloop, which for me is the best possible option, since I already have a dozen of the same. But it's AA sized, and unless they used a foolishly voltage-sensitive design, I would expect an AA to at least function. However the current supplying capacity of Alkalines is lower than NiMH, so it's possible that it wouldn't function fully - that seems unlikely though for anything that takes /hours/ to drain a NiMH.

Howdy Becky, These are a lot larger batteries that a normal "AA" battery. Normal "AA" are 1.5 volts, These are 3.7 volts. But they can be found on Amazon by typing in 18650 Batteries. Don't buy the cheapest you see Nitecore has a set of two with a charger for about $15 Prime. I have a set of these myself and they last about 8 hours while fishing. Once a month I let my light run completely down. Then I charge it completely. This helps the battery from developing what is call a discharge "memory." If you charge everytime it goes down to 1/2 time, the batteries will start to think 1/2 discharge is fully discharged. Hope this helps you out.

Different batteries have a different stated capacity. The greater the MAh rating, the more power the battery holds, and thereby the longer they will work in a given product.

I've never tried regular AA batteries in this flashlight. I only use the batteries they sell with them. I have another flashlight that uses similar batteries and I tried using regular AA's in that and didn't get near the power that I do with the rechargeable batteries that come with it.

I have tested AA and AAA alkaline and rechargeable up to 2500 ma in rechargeable. I have also used it with the CR123 3v lithium that my flashlights use with very good success. I have not tested any other batteries so far. My AA rechargeable batteries are the nickel metal hydride type. I have not tested the older nicad type rechargeable.

Short answer, yes. Long answer is NI-MH is a newer type of battery make up that can hold power longer than the older Ni-cd batteries.

To the best of my knowledge, any decent NiMH should work.... Its my opinion that the low discharge rate batteries, such as Imedion or Eneloops are the best batteries available these days, not since they offer the greatest capacity, but since their low discharge rate allows them to sit unused for greater periods of time, and still deliver when needed. A device such as the PortaPow might sit in your glove box for months or years before being needed. To then find the bats dead makes no sense.If you are using the portapow daily, well, I'd think there are better ways to charge your portable device....

This is what it says online when I Google your question: NiMH is an improved version of rechargeable batteries, they don't have the memory problem that NiCd's do. The only thing is you will need a special battery charger for them. Since the phone is the charger, then probably not.

Kinda late here, but with my experience Duracell provides the best though Eneloops have been known to work well in this device as well.This device won't work well on older NiMH batteries though, if the mA has been lost in the batteries this device won't charge very well.

I haven't tried it with NiMH batteries yet. I've only used regular Alkaline batteries in it. I used it on our last camp and haven't had to change the batteries yet. just love this light.
