Power up Your Devices with Powerex AAA 1000mAh Rechargeable Batteries, 4-Pack

Trev-R: While I found their AA big brothers generated too much heat to replace my Eneloops in camera flash, I bought these to replace the batteries in my BT TruCall phones which died within an hour of a call starting. I have to say these have proved to be excellent. I had a call with one of my children that lasted nearly 2 hours and there was still plenty of charge showing in the batteries. I can definitely recommend them for applications such as telephones and remote controls.

cocolisomadrid: Ya había co comprado antes esta marca de baterías recargables y quedé muy satisfecho. El cargador también es de la misma marca. Ofrecen una buena relación precio calidad. Frente a otras opciones de menor precio, estas me dan confianza y tiene mayor duración.

Peter: I'm into photography and so i've had a dire need to find rechargeable batteries due to the constant need for power of my flashes, that's when I found the Powerex brand. So far this brand has been reliable in regards to double AA batteries. Just completed first year of university and bought these Triple AAA batteries to use for my voice recorder and note taking. Unfortunately one of the batteries In the package was completely dead but the other batteries in the pack were perfect, no problems. Was able to use my recorder for more than 6 seminars/sessions on one charge. One seminar/session would take on average 90 minutes each. These batteries are sold separately from the charger so make sure you invest in one of the powerex chargers. This particular set of batteries doesn't come with a carrying case but can be bought for a few dollars more if need be.

qsbuilder: I always purchase Powerex rechargeable batteries which are reliable and charge them with my MH-C9000 charger. Overtime the cost is much less than regularly purchasing non-rechargeable batteries and is much kinder to the environment

assa: Soy usuario habitual de esta marca de baterías y puedo decir que son una buena compra.
Tienen una buena capacidad y soportan gran número de cargas/descargas. En la oficina se usan desde hace más de seis años sin ningún problema y con ellas se han ido sustituyendo otros modelos. He de distinguir estas de 1000 mAh frente a las de 950 mAh, que en algunos aparatos no funcionaban correctamente.

E. Block: The batteries are very good, but rechargeable's seem to leave a bit to be desired. The Powerex charger works very well, and the batteries are great quality, but rechargable batteries don't charge to the voltage level of non-chargeable batteries so in many situations they show up as low voltage as soon as you plug them in. Also, after a charge they begin to lose voltage immediately so if you charge them an put them in the cabinet, by the time you need them they are only 75% charged. They seem to run out quickly.

Doctor Gangreene: I needed batteries for my TV remote. Tada: Powerex AAA 1000mAh rechargable NiMH! You might have to charge these things up when you first get them. But after that you shouldn't have to recharge them for a while. I'm still on my first charge and these have already lasted as long as the old single-use batteries did. If you need batteries for your remote, and if the price is right, you might as well give these a shot.

TV remotes are LOW-POWER devices, so batteries last a long time in them. If you want batteries for a digital camera or some other HIGH-POWER device, then I can't really comment on the performance or lifetime of these because all of my high-power stuff runs on more specialized batteries than the AAA format.

C. Cornell: I like these batteries a lot, and it may sound a bit odd, but I prefer the AAA batteries by PowerEx then PowerEx's AA batteries. The reason is that I noticed, and even checked the capacity on both the AAA's and the AA's after they were sitting around for about 4 weeks, and I noticed that the AAA PowerEx batteries were more or less at the same capacity levels but that the AA batteries had dropped by about 10%.

I used the LaCrosse C-1000 Smart Battery Chargers Charge/Test function for all of my tests. My good ole trusty LaCrosse 1000, as a much much better reviewer that I could ever be always says... Original quote attributed to our own master Engineer and Top 100 Reviewer, Mr NLee.

Anyway I like these batteries so much because I use them mainly for my high intensity 200XL Lumen Maglite flashlight, my Maglite 50XL high intensity light, and my old and trusted LED lamplight with a headband that I use often for doing equipment and item repairs that are very tiny in nature. And since I use the mags for work often
enough and they are high energy consumption products I noticed that the AAA 1000Mah batteries by PowerEx were seriously outlasting most of...

Liberty and Freedom: I bought a tiny little external flash (Sony HVL-F20AM) that called for AAA batteries. Since NiMH batteries generally perform best with this type of equipment I found these. They have the highest manufacturers' mAh rating I could find for this size battery. I've used Powerex AA cells in the past with much success and I highly recommend them as this brand has proven itself to be among the best out there.

Since this is my first set of AAA rechargeables, I can't cite any prior experience with other brands for this size to give an informed basis of comparison. However I can say they seem to perform well for their intended purpose.

As I do with all new rechargeables I set them up to "break in" mode on my Maha MH-C9000 charger analyzer (which I recommend) using the preferred settings for this type of battery. I was a little disappointed that none of them broke in at or above 1000mAh; it's been pretty cold around here lately and maybe this affects cell performance (cold December week around here). Here were the results for all 4 cells after break in cycle and fully charged for the first time:

Cell 1 - 962 mAh, 1.42 volts
Cell 2 - 959 mAh,...
