High Capacity Rechargeable Double A Batteries

These are the best high-current non-rechargeable AA batteries on the market (effective capacity of up to 2x that of recheargeable Eneloops). B&H had the best price, and delivered them fresh (they were made in August 2011 and guaranteed to last till year 2026 in storage).

I use it with the normal and high capacity batteries, it works.

My message is the same as for the AAs... These batteries have a higher capacity than any other rechargeable AAAs I have ever had. Do yourself a favour... buy these and forget about the others.

Eneloops have long been the best rechargeable AA batteries out there and I have dozens of them. When I ordered these I got worried becauase the name on the package changed from Sanyo to Panasonic and I was not sure if they changed them for the worse. When they arrived they looked the same except for the Panasonic name so I put them in the Maha/Powerex charger on break-in to test the capacity. Out of the 8-pack the lowest capacity was 2001mah and the highest 2036mah so I have no complaints. The name on the box changed but they work just like the Sanyos, will buy again.

I purchased this, not for analyzing rechargeable batteries, but for measuring capacity of several different brands of lithium AA batteries. There is a common knockoff of this product that didn't actually work for my use case, but I did use it for charging batteries, and I can say that the user interface of the Powerex is much more intuitive and easier to use. As far as customer service, I emailed Powerex to find out if this would do what I was trying to do, and a representative called me and let me know that while it is not an officially supported use, it would work, which proved to be true. I would definitely buy more products from them after having that experience.

I have several of these along with the larger capacity ones.They are great to have for back up rechargeable aa batteries.I use them at events when I'm usings speedlights & they are very covenant to have in my pocket instead of running back to my lowepro rollers to get fresh batteries.

More than double the capacity of the WCU/ Sony M Batteries from the prior generation. These give you the digital readout on your hand unit and charge pretty quickly as well. Have yet to use more than 1 in a 12hr shoot day, so 2 is more than enough. Pretty decent price as well.

If you love the Flex you love this Plus with the double battery capacity! Pair it with the Lit22 batteries for LONG lifespan! Pictures & video quality are crisp and clear. No issues setting up with the Spypoint App! Definitely a great investment!

I like the display that indicates how far along the charging is. I rarely let two batteries run out so I don't know how well the double capacity works

Quality rechargeable batteries.
