PowerexMHRAAA4 AAA 1000mAh 4-Pack Rechargeable Batteries

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 oftenenough and they are high energy consumption products I noticed that the AAA 1000Mah batteries by PowerEx were seriously outlasting most of the rest of my collection of high capacity batteries.PowerEx Maha 950Mah are pretty good also, but nothing lasts as long in those flashlights then the PowerEx ones do. I seriously don't have to change them for a month to six weeks at a time. It something that I don't particularly notice while time is passing, I do have a life, really... But it is always a surprise to me when the LEDs start to fade out. And I realize that I haven't had to charge any AAA batteries that whole time.I have been using high capacity batteries like PowerEx, Maha, EneloopXX for a while now. Probably about 3 years or so. And I do realize that there are plenty of people who have used them much longer then I have. But I also use rechargeable batteries for all of my on-site power tools as in Dewalt Hammer Drills, Drivers, Regular 20 volt drills, etc.. And I also have a couple of pretty good solar powered systems I set up so over a bunch of years I have used a lot of different power level rechargable battery systems and I have a decent amount of my own experience using them.So I have developed a decent sense of which batteries are strong and are running and will keep running with a lot of power and which brands are going to fail prematurely. I can see how well (or how bad they are) just by using the device or tools where they are in and feeling out instantly how well the tool is working or how strong and how far the throw range of the light from those killer maglite high intensity flashlights are. :-). As examples.And I am very happy with the PowerEx's AAA 1000Mah batteries, I use them all the time and I certainly recommend them highly. If you buy these but haven't bought a smart charger to charge them with, I also would strongly recommend buying yourself a smart charger like the LaCrosse C1000 or the PowerEx Mh C9000 Wizard One. It will be well worth it for you.As to which of those two chargers I prefer... Well that's a whole other 2 reviews, right?!!

I have gotten a number of different rechargeable batteries through Amazon. I found these to be more powerful and last longer with charge than the other triple A i got. however, these are rated higher at 1000mAh rather than slightly lower Sony 750mAh. I have continued to use the rayovac and sony plus another off brand i forget for 5yrs on them and still keep a charge for an appropriately long time. far longer in the devices and lasted at a good recharge level for lots longer in time, too. I did not expect these particular ones to give me any trouble at this early date either, based on performance of older ones. I have not had any issues at all with these. I use them, though, in my wifi mice, ir, laser logetech mostly. these seem to have the bit more power for the better keyboard and mouse i got from microsoft. lasted and not needed to replace in my microsoft m700 series and in another remote control but that i expected. I am totally sold on these NIMH rechargeable batteries. long lasting, multiple recharges, based on prior past performance and huge money savings over throw away batteries. not to mention keeping batteries out of the dumps and other hazardous material sites. as if people actually pay attention to that for such small items. so far very good, another year or so will tell. i had intended these for a camera and flash but didnt get the right size.so use these in less demanding devices . price was right, though a bit higher than other name brands a few yrs ago before though they were less than 1000mAh

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 voltsCell 2 - 959 mAh, 1.42 voltsCell 3 - 929 mAh, 1.41 volts (runt of the litter)Cell 4 - 962 mAh, 1.42 volts

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.
