Powerex AA 2700mAh NiMH Rechargeable Batteries w/holder- 4 Batteries Per Pack Reviews

• Powerex Batteries -excellent investment!

  
  By ANOEOHRLK11P0 on 2008-01-20
  I've been using various Powerex batteries to run my power-hogging Minolta Dimage 7Hi since 2002, and in that time have occasionally tried some other rechargables... not a single other rechargeable has come close to delivering the output of the Powerex's.
  
  My most recent purchase was two 4-battery sets of the 2700 mAH versions, and they have been just superb.
  Not many people know that it is recommended to recharge your batteries every month to keep up their capacity and if this is not done the performance can degrade.
  
  Even excellent rechargeables wear out, but you can expect a couple of years of great results from these, highly recommended for high-demand digital cameras.
  
  In this time, my original Maha MH-C204F charger has provided faithful service and is still working fine. If I were getting into the rechargable game now I'd go for the MH-C9000 WizardOne Charger, because it treats each cell individually instead of in pairs.
  
  Glad to see Amazon is finally offering Powerex.
  
  
  

• Maha Powerex 2200 & 2300

  
  By A36UWKHF4XUY17 on 2006-08-27
  I own the 2200 and 2300 series batteries and love love LOVE them! They are inexpensive and last seemingly forever.
  
  Last year I helped document a project my classroom was doing for Very Special Arts. I charged up batteries and brought a spare set for just in case. I took over 1000 pictures and filled up my memory card before I ran out of juice in the first set of batteries. The other camera used to document this project ended up being the secondary camera because they kept having to stop to recharge the battery.
  
  Because of how reliable these batteries have been I have started basing electronic purchases on if they take AA or AAA batteries or not. I have saved a lot of money because I don't have to buy spare stock batteries. I have 18 Powerex batteries that I use over and over for the past 2 years and haven't had any problems with them.
  
  The charger is simple to work and holds the batteries to charge better than other rechargers I have owned. There is a feature to discharge the batteries should you need to do so.
  
  I can't begin to imagine how much I would have spent on regular batteries had I not gotten these.

  i have two sets of four and the powerex charger. i charged up four and put them in my camera when i got it in january 06. last week those original batteries finally ran out of juice. i use my camera quite often and was amazed how long these batteries lasted. simply the best choice for rechargeable batteries on the market.
  
  

• Awesome rechargeable batteries

  I did lots of research and selected these batteries for my digital camera. They last forever, just like everyone said they would. They are by far the best AA NiMh rechargeables I have used!
  
  

• Powerex 2700mAh AA Battery

  
  By A2UKI12SQMIQ79 on 2008-02-14
  I buy 2 sets of 2700mAh Powerex for my new Canon S5IS camera. Before I have used 2 set of 2500mAh Energize and I was able to made 500 photos with flash or without. At the same condition, with Powerex 2700mAh I have realy shock to see that I finish the second 2GB SDcard. Total, 1300 photos plus 10 min of movie. Also the flash increase the charging speed considerabil.
  Great product. With o slow charge (200mAh) the battery stop around 2650 and 2710 mAh capacity.
  
  
• Maha/ Powerex 2700 mAh _4.5 Stars_a TOP performer !
  By AKRSSC2ETWTNB on 2008-02-20
  Top rated batteries and top manufacturer. They run at least 2xs LONGER than lower capacity (2000- 2200) mAH batts. I also compare their better performance & Run time in my previous review of the 4-pack eneloops. These quality 2700 mAh batts outperformed those 2000 mAH batteries by an Addtl ~ 48+ hrs, in [continuous] RUN time & illumination in my led string lights...
  
  One review, elsewhere, reported these Powerex batts to be shy of 200 mAh. The (minimum) on the label reads 2500 mAh, perhaps that person tested it when not [fully] charged. NO two cells/ batts are exactly the same, but so far I've only known one @ the lowest to be down by ~60 mAh. Yet, they average above 2700 mAh.
  -These batteries have been ranked TOP pick in a number consumer tests!- search ur self...
  
  Sanyo's 2700 mAh (AA)batteries are very good too. These two brands are the true contenders(right now). I would pick 1 over the other, based on sale price or latest technology release. If I see a battery comparison on Sanyo Vs other brands w/out incl. Maha /powerex - I would question some bias present.
  
  It's obvious that Maha/ Powerex is not as well known here, maybe b/c they're not often sold in typical retail chains. But they're no stranger in the professional shops, Photo magazines & online! - I'm saving 0.5 stars for when Maha releases an (AA) with even higher mAh!- not certain when, but fingers crossed...
  ----shop around 4 these- sale prices vary...
  
  
  
• Good but 50% success rate right now
  By A24DS21M89YFK5 on 2007-12-15
  Bought these plus the Powerex charger last March 2007 and it is now December 2007. After 2 months, 2 pieces displayed rust on the + and - ends of the batteries...the other two are ok. They all still work until now though although I've noticed that the rusted ones have less charge. I like them though and I've decided to buy 4 more to test again since I am more or less ok with the product. They are especially good for remote control toys since they last a long time. :)

• Worth the money!
  By A1N86C36C213C on 2008-06-10
  I am a wedding and portrait photographer, so I am always on the lookout for long-lasting, quick recycling rechargeable batteries. I have tried Lenmar, Wewin, Calumet and Energizer batteries for my strobes and the Powerex have outperformed them all. In particular, when charged in a Maha charger, these puppies will last! You can't go wrong with Powerex.
  
  
• Buying more PowerX batteries
  By A28LKL1NM5RIHS on 2008-07-19
  I currently own 8 2300 mAh batteries, purchased 2 years ago. Not one problem with them and they are still going strong, maybe not like new, but I can't measure the difference.
  
  12 of some off-brand name AA's I have went to the great beyond and need to be replaced and am purchasing 8 2700 mAh PowerX batteries today.
  
  I use them in my Canon580EX II and Metz 54 flash units. A portable power pack costs more, weighs more and is a PIA to carry around. These hi-mAh batteries give a big bang for the buck and the plastic carry-case's can be carried comfortably in your pockets.
  
  Plus I use them in my Oly C-5050 and as stand-by for my Canon 5D should I run out of juice from the Lithium Canon Batteries. They are also used for my portable TV, AM/FM radio, aircraft headsets and race track radio gear.
  
  I also have 2 Maha MH-C401FS 1 hour chargers and I can't praise them enough. You can actually tell when one cell is failing because it takes longer to charge (red light stays on) since each battery is charged independently from the others. That is also a very good buy.
  
  I don't know anyone who uses the Sanyo brand so I can't comment. I am a pro-photographer.
  
  
  
• Great batteries
  By A203VBHL0LJCZ0 on 2008-08-16
  This is the first time I have purchased rechargeable AA NiMH batteries. I purchased them specifically for a Canon 580EX II flash. Flashes eat up batteries. I have also used them in my MineLab metal detector. The batteries have worked great and I am very pleased with this brand.
  
  
• These die after months of use
  By A307Y3LMCVEZS1 on 2008-08-24
  Powerex AA rechargeable batteries
  
  Although touted as having the power necessary to run digital cameras, these 2700 mAh batteries will last you less than a year. Unlike the current crop of batteries designed to hold charges for extended periods, these batteries won't stay charged in an unused digital camera for more than a day after a few months of use.
  
  I checked to make sure it wasn't my camera draining the batteries- using Eneloops, it was clear there was not a power drain problem. Using the batteries in an electric toothbrush, I again found the power falling off rapidly after a couple of days of non-use.
  
  Testing conditions for these were meant to be ideal- the batteries were kept in a Powerex AA battery charger specifically designed to maintain charge and condition the batteries. Despite this, after several months of very light use, batteries taken fully charged out of the charger and put into a camera would hold a charge for about 2 days before burning out. Under the exact same conditions, my Eneloop batteries would hold a charge for many days, maybe weeks. Initially the Powerex batteries could hold a charge for several weeks, but this capacity was quickly lost after about 9 months.
  
  Therefore if you're looking for long-term savings on AA batteries by using NiMH rechargeables, stay away from Powerex.

• Awesome!
  By A16AQMYL44LHRN on 2006-02-21
  The best rechargables I've ever owned. They last forever in my digital camera. I charge them with the MAHA MH-C204W Battery Charger, which might be a factor.
  
  
• Best AA batteries I have ever owned.
  By AU5U16YWAIYZP on 2008-05-20
  These are without doubt the best AA batteries I have ever owned. I used these during wedding for my flash unit which usually really sucks batteries dry. I was going through two sets of Duracell batteries for one wedding. These PowerEX batteries lasted the entire wedding and beyond!! After using these batteries to shoot the wedding I discharged the flash manually using full power an Additional 72 times before they worn down!!
  
  
• The Gold Standard in Rechargables..
  By A4B8RDZ5DKEP6 on 2008-07-01
  This is the #1 rated and #1 selling ni-mh battery in Japan for a reason. These are infallible, even after a year of use, they keep on ticking. The charger is great too. It regulates and even has a setting to empty the batteries before you charge them. Just a higher class of rechargeable.
