## Description

The Powerex MHRAA4 Rechargeable AA NiMH Batteries (1.2V, 2700mAh) - 4-Pack is a package of 4 AA nickel-metal hydride (NiMH) batteries. They have a voltage of 1.2V and a capacity of 2700mAh. The batteries can be recharged hundreds of times, and because they have memory-free operation, they will not develop memory effect, which can cause batteries to hold less charge. These batteries will retain a charge at or near their full capacities even after hundreds of charges. A battery carrying case is included.

Review: Longest Lasting AA Batteries, Period - I've owned and tested everything out there, and this is the best in terms of mAh yield. I own a half dozen sets of these, and they all test at about 2600 mAh after refreshing. For reference, the duracell "2650 mAh" batteries test at around 2500 typically. Yes eneloops are great batteries, and HOLD a charge like nothing else (unbeatable for photographers who leave them sitting in the camera bag for long periods), but they can't match the raw output these batteries give. These batteries are designed for people like myself (regular scanner user)who go through a set of batteries every few days to a week, so that self-discharge isn't really an issue. You can't go wrong with these batteries if you rotate batteries at least every 1-2 weeks. If you want batteries that sit for long periods and hold a charge, buy eneloops, but realize they don't have the endurance these have. *****TIP: If you are serious about battery performance, you need a good charger that can refresh batteries, and can test them, display actual capacity, and charge at various rates. Remember that a set of batteries is no better than the weakest in the set, and unless you test, you might never notice that one is weaker than the others. A good refresh charger can often bring this weaker battery up to snuff with the others, and you can see the test to prove it. If it remains weaker, you can match it with weaker batteries for matched sets. Keep in mind, even great batteries like the Powerex batteries, sometimes need to be run through refresh cycles when new to get them to full capacity. Batteries that sit for a while also benefit from a refresh. Check out the AccuPower IQ328 charger that runs about $35 if you look around. It does all of this, and helps you get the full value out of top of the line batteries. Also, if possible keep charged sets in your refrigerator to slow self-discharge. Good luck.
Review: My experiences with Powerex 2700 - I've only had these for three months now. I've used them in two cameras. The Canon powershot sx10is, and my powershot A710is. I just got back from Walt Disney World. I shot a lot of video using the sx10is. I recorded entire shows/parades etc. No failures experienced.Shot all that video, and still had plenty of juice to take flash pictures. The sx10is has a monster zoom as well, so there's another bite out of the batteries as well. I've taken quite a number of pictures and video since owning these. What I also find refreshing is not finding them dead after a short space of time while not used. Finding dead batteries started to be common with another manufacturer I won't name. I also use these batteries in my portable bearcat scanner. I've gotten around 16 to almost 17 hours of continuous on time out of these powerex batteries. I have two of the Powerex eight cell smart charger. Since all I use are AA batteries, this charger is ideal for me. When I bought these batteries, the very first thing I did was condition them. Based on the results i'm getting, i'd say that's the way to get started. I've read some of the reviews here. It's not my intention to question anyones negative experiences here. Sometimes things just don't work as well as they should. That happens unfortunately. As far as longevity goes, my experiences with batteries like these is, they only have a limted life span. (like us, only shorter) They can only be charged/discharged and charged again so many times. I feel that if I can get a complete year of this kind of performance, then I feel i've gotten my money's worth. Digital cameras are extremely power hungry and put one heck of a drain on batteries, or so it sure seems to me. Overall, so far, i'm happy with the performane. If things turn sour, I will update this review to tell you. I've eaten crow before. Just pass the salt if I come back with bad news.

### ⭐⭐⭐⭐⭐ Powerex Battery and Charger Overview
*by L***E on July 2, 2011*

BACKGROUND: I wanted a NiMH AA/AAA charging system that would remove the "mystery-of-the-charge" and provide more confidence in the rechargeable batteries I purchase. So, I did a little research like everyone does (or should do) before buying an item that's intended to last for years (find "The Best (aa/aaa)Charger Guide by John Dziadecki on Amazon - excellent read). I decided to buy two 4-packs of Powerex AA 2700's and two of Powerex AAA 950's to supplement some Duracell 2650's, Kodak 2550's, Energizer 2500's and an assortment of generic 2300's. I also bought two chargers: the MH-C9000 and the MH-C800S. For years I've used an assortment of chargers with idiot lights. I had no idea HOW MUCH of a charge those batteries were getting or whether they really held the advertised capacity. But, it was very clear (and frustrating), that some of these batteries and/or chargers were very limited (junk?). I'm not sure how many times I installed newly charged NiMH batteries into a digital camera only to have the low battery icon show up after a couple shots: "Hmmmm...how many of these batteries are duds?" And, generic battery testers really don't tell you much, i.e., how 'good' is "Good"; How 'low' is "Low"? .....So, it took me a while to get fed up. MH-C9000 Charger: This thing definitely took most of the guess-work out of my rechargeable AA/AAA energy supply. I was able to get rid of six old NiMH AA's in the first week and "rescue" seven others with this charger. The directions with the charger are a little sketchy but, if you know the advertised capacity of your battery and its age, you'll be able to figure out how to best charge it and how many mAh's are available to you afterwards. You'll also be able to determine if the battery is shot. This isn't something you get to do with idiot-light chargers (which work just fine for lots of people). I remain very impressed with this charger. MH-C800S Charger: I bought the MH-C800S to supplement the -C9000 because of its 8-battery capacity. This charger does not provide battery capacity values at the completion of a charge cycle. It does however, have a 16-hour 'conditioning mode' designed to re-juvinate and cycle (discharge and recharge) batteries: it works very well. If you don't care about actually 'seeing' the specific capacity of your batteries, the MH-C800S is a good choice at the right price. It too will tell you if your battery is shot. This charger is all that most people will need or want for AA and AAA re-chargeables. CAPACITIES: I have not used Powerex re-chargable batteries long enough to comment on their discharge rate. But, thus far I haven't seen a difference between my older 2300 and 2700 mAh re-chargeables and the Powerex batteries. It's also too early to determine if the Powerex batteries will last through 1000's of charges. The Powerex AAA batteries have an advertised capacity of 950mAh. They charged out between 956-967 in the MH-C9000's "Break-In" mode. Allowing for heat attenuation, full capacity is about 920. I'll know more when I recharge them. The Powerex AA batteries have an advertised capacity of 2700mAh. They charged out between 2556-2650 in the MH-C9000's "Break-In" mode. Allowing for heat attenuation, full capacity might be about 2300. I'll know more when I recharge them. Some of my older batteries charged out at significantly higher rates than advertised after putting them through the MH-C9000's "Refresh and Analyze" mode: these older batteries are holding charges longer and they discharge more consistently. I can tell that those instances of partially-charged batteries screwing up the camera's current requirement will be fewer. At least now, I'll be able to sort out the weak, lame and starving in the herd. SUMMARY: Of course, there are other ways to do what I did. The Powerex battery purchase was based on the charger purchase: I figured it best to stay with a certain brand and keep the system homogenous. Not necessary at all. The price was right for the batteries and they came with convenient storage cases. In time, if Powerex batteries don't perform well, I'll probably start replacing all my batteries with an assortment of Sanyo Eneloops. I'm in the process of learning what a good rechargeable AA/AAA battery really is. There are several other chargers that perform similar to the MH-C9000 and -C800S: LaCrosse, Sony, and/or Sanyo. Reviews for the Powerex MH- products appealed to my technical comfort level and budget. Good stuff!
