Sanyo 2,700 mAh AA NiMH Rechargeable Batteries (4-Pack) Reviews

• GE/Sanyo Rechargable Batteries

  
  By ARC7QMDO889XX on 2006-12-09
  These are very good batteries. I charged those in my La Crosse BC-900 Charger. The following were the results after first charge.
  
  The four AAs rated 2700mAh nominal (min 2500mAh) come out ranging 2.8Ah to 3.0Ah. I used the discharge setting of 250mA and charged at 500mA. (Those who use the BC-900 will know what I am talking about).
  
  The four AAAs rated 1000mAh nominal (min 930mAh), all come out above 1000mAh, but very close to 1000mAh. I used the discharge setting of 100mA and charge at 200mA.
  
  

• Not all batteries are created equal--these beat the pack

  
  By A1GALZCXD8FHOR on 2007-04-25
  I recently purchased a digital camera with an excellent reputation, save for its long recycling times for its built-in flash. Most of the reviews I'd read of that camera said it took about five seconds to recycle the flash.
  
  Hoping to do better, I purchased these GE/Sanyo nickel-metal hydride batteries. My own tests show these superior batteries take only two to three seconds to power the flash on my camera. That's nearly fifty percent better performance than from other batteries. Even non-rechargeable, high-end alkalines can't beat that performance.
  
  Best of all, the price for these is better than other name brands of NiMH AA batteries.
  
  Better than expected performance and a great price--that adds up to five stars.
  
  

• Sanyo 2700 mAh - one of the best

  
  By AKRSSC2ETWTNB on 2008-02-20
  These are quality batteries w/ 2x's more power and [Longer RUNNING time] than most lower capacity NIMH batteries, including the "ready to use"/ Low self-discharge (LSD) types!
  
  Never thought I would care about writing battery reviews, but the High capacity rechargeables are getting a bad rap from some reviewers b/c they have to be charged (before) use, in order to get back their capacity, after being left (un-used) for more than ~ 3-4wks. Their stored power when [NOT in USE / device turned OFF] is lost faster than batts that keep hold of theirs longer = the LSD types like Imedion 2100 mAh -or- Eneloop 2000 mAh.
  -BUT these high capacity batts (2700- 2900 mAh) have an intended purpose, which is a reason the top companies make Both types in the 1st place.
  
  [In Storage]
  Yes, the LSDs are useful b/c they have a [Longer STORAGE time] (before needing to be recharged) than the high capacity types. Thus the LSDs are "ready to use" and good for seldom used devices & intermittent usage. However, this doesn't negate the effectiveness of 2700-2900 mAH made by quality brands.
  [In Operation]
  Not all users (all the time) need a rechargeable for good shelf-life... Some need it for High power & LONG run time for "shorter" segments = 1- 20 days (i.e., photo shoot, day-hike/bike/caving, day at the beach with ur RC (radio-controlled) toys, holiday lighting, etc, etc. And a quality brand (2700-2900 mAh) will do the job.
  
  The decision is [WHEN] do you pick a :(High Capacity/ high self-discharge) -or- (Low Capacity/ Low Self- discharge)...Not picking the universal "better" one. The "best" would be a High capacity & LSD & Rechargeable all in one!- but that's not available yet.
  
  Now, Sanyo's REAL competition is ( Powerex AA 2700mAh NiMH ). They're both good -I would pick 1 over the other, based on sale price or latest technology release.
  
  
  

• Amazing Batteries!

  
  By A32ODAXDO95III on 2007-04-05
  I've used a number of types of rechargeable batteries from various companies in the past. I bought these batteries to power my Olympus FL50 flash for my DSLR camera. Other rechargeable AA batteries only last for 150-200 flashes, with a slower and slower recycle time in between flashes. These Sanyo batteries lasted me over 1500 shots on one charge, with less than a second of recycle time in between flashes; that is simply amazing.
  I highly recommend these batteries to anyone who has a power intensive device that requires a quick recycle time.
  
  

• Good

  
  By A3TBVWG08O3RM6 on 2006-11-17
  This batteries work just good, they have a very high capacity.
  On it's body you'll find written that the total capacity may
  vary, but a minimum of 2500mAh is garanteed. This could be
  written in the product description...
  
  
• So far the best
  By A34UQJ1BZRU5Z1 on 2008-03-14
  I use AA batteries as part of my job. Plowing through as many as 15 to 20 a day in my alkaline days. Several years ago I made the switch to NiMH rechargables for both environmental and economical reasons.
  
  I can safely say I have tried just about every make and capacity of AA NiMH battery out there and the Sanyo 2700mAh are, so far, the best for the money. I use high drain devices so the lower capacity batteries end up being too much of a hassle to change all the time. These fit my purposes perfectly.
  
  If you are looking for some AA for your remote control or some other low drain devices go with a cheaper NiMH but for high drain devices these are the best.
  
  
• AVOID "Eneloop" - buy these instead
  By A203OCQQ12MAVT on 2007-11-03
  The 2700 mAh sanyo / GE battery comes in different colored cells (some white/orange some silver/green but the same battery). In all my testing the 2700 GE/Sanyo has been by far the best NiMH AA.
  
  The eneloop scheme means the batteries come "pre-charged" but only hold 2000 mAh, or about 75% of these. You pay every time you use them for that convenience of having it charged when you get it. That's a Win once, loose a thousand times in a row scenario. You can't even get those odds in Vegas.
  
  The 2700 has consistently been a top performer, exceeding MAHA's offering at 2700 (which comes out 2500 on their own tester). In real use, products that would run for 1 day on "normal" 1850 mAh cells or NiCd cells run almost 2 days on the 2700 sanyo's.
  
  Trying to find these has been difficult. I bought some 2 weeks ago and now they are "unavailable" - HELLO AMAZON - RESTOCK THESE - Christmas is comming and we need them!
  
  Finally - these offer tremendous current capacity so your cameras and flashes will charge and operate faster.
  
  Having tested over 2 dozen brands and sizes of batteries, these came to the top of the pack quick. At 12.99, their price to performance number was excellent too. You can pay more, but you can't find a better performing cell.
  
  
  
  
• Great capacity
  By A3SJQG2SEME1PM on 2007-04-12
  I bought these batteries a couple of weeks ago, Amazon delivered them on time and I have no complains. I charged them with the LaCrosse Technology BC-900 AlphaPower Battery Charger which is THE charger and got 2730, 2660, 2690, 2610mAh out of 2700 nominal after using the refresh mode at 500mA. Great batteries.
  
  
• Excellent lasting power
  By A30OEDORRGFX3U on 2007-05-12
  These batteries last extremely well in my Canon S3 IS camera and seem very satisfactory indeed. They recharge just as quickly as others but last longer.
  
  
• as good as a good battery has to be
  By A2Y2N1D4TA15NM on 2007-03-18
  I like this product.. together with my Sony BCG-34HUE Quick Battery Charger , i think i've got the best of the two worlds
  
  
• Superb Batteries!
  By A18HE80910BTZI on 2008-03-04
  
  This review is for Sanyo 2,700 mAh AA NiMH Rechargeable Batteries (4-Pack) As all the reviewers have already noted this is the best set of MiMH rechargeable batteries you can buy period!
  
  I have a set of Sanyo/GE batteries which I had purchased in 2001 and they still work like new, That gives you an indication of the quality of batteries we are talking about.
  
  The Cells are MADE IN JAPAN excellent Quality, Lasts forever, Ideally suited for Digital Camera and high drain portable equipments.
  
  A General word of caution: Take care of your rechargeable batteries, never charge them in RAPID chargers which charges batteries with high current within a short period of time, overheating during charging can significantly reduce their life span. Never short circuit batteries and never discharge them completely.
  
  Buy with confidence! These are very good batteries.
  
  
  
• Good performance; good capacity
  By A362ZCUZ2TNAHP on 2007-05-07
  While I have only had these in service for 2 months, they are, thusfar, performing well. They have superior capacity, with a rating which seems to be closer to the truth than some others. Their rechargability has been excellent. Regarding long term reliability: I will need to wait to form an accurate opinion. While most would prefer a lower cost, I prefer not to sacrifice performance to achieve it.
  
  
• best i've had
  By A1A7S2925EKJC9 on 2007-05-24
  after using duracell, energizer, kodak and a few others, i got these sanyos and they are by far the best ones. now, the bc-900 charger makes a lot of difference too.
  long life, well built. last 30% longer than my previous 2500mah energizers.
  
  
• Excellent Batteries
  By A2II6DX37NU0UI on 2007-09-13
  These batteries can run for a long time on high drain devices. I use them in my mp'3 player and digital camera regularly and I can usually expect about a days worth of on and off usage. I previously had the Sanyo 2500 mAh and were impressed by their charge time and the amount of usage time that i got out of them. However with a big trip coming i decided i needed some more power to carry around with me so i opted out for these. Fast charge time using Sanyo's Super Quick Charger. I highly recommend this battery. If you buy these you know that you'll be getting a quality and reliable battery.
  
  
• * Best rechargable AA to date
  By A111WCF2569629 on 2008-02-08
  When talking about batteries, there should not be a long review.
  
  The Sanyo 2,700mAh have fantastic capacity and they hold a charge.
  I also have Eneloops and they're good, but if I was to choose between the two, I'd take the 2,700s'
  The way I look at hardware,...if I have to think about it,...its not preforming well.
  
  I don't have to think about these cells.
  
  
  
  
• Truthful advertising
  By A2D1TIEENXAP6Q on 2008-04-25
  These cells state a 2700mah capacity. But since cell capacities are frequently overstated for competitive reasons, one should always measure the effective capacity in your application. In my application, I expect a 400ma constant current drain. So I charged 4 cells and then discharged them at 400ma and recorded the capacities. They were quite uniform, which alone speaks to the quality of the cells, and had an average capacity of 2450mah. Yes, that's less than the 2700mah rating, but that rating is usually a 10 hour discharge rating. That is, at 270ma constant drain, the cells will take 10 hours to reach terminal voltage. So 2450mah at a 6 hour discharge rate tells me that Sanyo is justified in claiming 2700mah capacity. And there are lots of cells out there for which this is not true (like SunPak).
  
  
• The strongest NiMH batteries available
  By A53CILMCOOH3R on 2008-09-12
  First off - you need a good charger to get the most out of these batteries. Check out the BC-900 charger or the Maha chargers that have a display and can refresh or break-in a set of batteries.
  
  After reading the other reviews of this battery and having used Sanyo's awesome Eneloop battery, I had to give these a try in my external flash.
  
  Since I shoot weddings, I need something that helps speed up my flash recycle time and can last all day. These batteries fit that bill, and then some.
  
  When I first got them and put them in the BC-900 charger (if you don't have one, get one - it's great.) That charger has a refresh mode that they recommend for new NiMH batteries to break them in. The first pass showed somewhere around 1500-1700mAh, so I was obviously a little concerned. I have two of those chargers and two sets of these batteries so I set one full set to 1000/500 cycle and the other set to 700/350 (BC-900 owners will know what this means.) After letting them run all afternoon and overnight, the 1000/500 set came out between 2610-2720mAh. The 700/350 set is hitting a high of 2760mAh but the whole set hasn't finished yet so it may go even higher.
  
  Some brands increased the size of the battery slightly to be able to jam more capacity into the battery. Sanyo appears to adhere to the original AA size so getting them stuck shouldn't be an issue.
  
  As of right now, Sanyo is definitely the king of the rechargeable battery hill. If you need a battery that can hold a charge for a long period of time, check out the Sanyo Eneloop battery.
  
  
• Great Rechargeable!s!
  By A25ZNS3UGB69M0 on 2007-07-12
  I can only say.. amazing.... these batteries perform far better than I expected... we shoot all day and do videos with there batteries never needing to be changed!
  
  
• Outstanding Capacity - Great Quality
  By A1FO25XCT4VAEE on 2008-02-23
  I'm using these to power my Canon 430EX flash unit. Right after I bought them, I did a slow charge overnight to get them to full capacity. Then, I placed them in my La Crosse BC-900 charger/discharger to cycle them and measure their capacity. All four batteries were within just a few mAh of each other and the capacity of each one was right at or over their rated 2700 mAh.
  
  They now have several charge/discharge cycles on them and they are doing great. They don't seem to self-discharge as fast as some older NiMh batteries I've used.
  
  As of right now, I don't know of *any* AA battery that has a capacity of more than 2700 mAh. Sanyo is well known for their rechargeable batteries and these prove to be consistent with Sanyo's high quality.
  
  I don't expect them to give me any problems, and if they last beyond several cycles, (I know they will) they will have paid for themselves over alkalines.
  
  Very satisfied user.
  
  
• Lived up to expectations
  By A238PGYLOZVPTV on 2007-10-23
  I have used these batteries for about a month now and I have to say that I am satisfied with their performance. I have a Canon S2 which uses for AA batteries and can be quite resource hungry with me shooting 300 pictures a weekend. So far their recharge time has been good as well. It remains to be seen how well they hold up in the long run.
  
  
• Long lasting for an excellent price.
  By A3MS8VYX6PH4AF on 2008-02-08
  These rechargable batteries are some of the best I have owned. They last a long time, and their shelf life is good too. Great value.
  
  
• A very high quality battery
  By A26DYT832JV4O4 on 2008-04-23
  I have been using Sanyo NiMH rechargeables for several years now. I am impressed with the quality, and the price is quite reasonable through Amazon. I recharge them in a LaCrosse Technology charger that I also purchased at Amazon. As with any rechargeable, the slowest recharging rate is the best for long life (it minimizes heat generation in the battery). The LaCrosse lets you select the charging current. The batteries are mainly used in a Nikon SB 800 flash, and, although I haven't counted the number of flashes, I've never run out of charge (150 pictures taken one day). The 2,700 mAh is bigger than many other AAs, but the charger handles it fine.
  
  
• GR/SANYO rechargeable batteries.
  By A394FH5HQXXA14 on 2007-02-11
  I have only had the batteries for a short time, but they are working great. I have recharged all three sets "4 per set" three times each. (that's what taks to run my Canon PowerShotS2/I2 camera)all good news.I take a lot of pictures and I need 3 sets to keep me going for about 6 hours.But I know that I need another 3 sets to really keep me in the field for the day. I do alot of back packing and long walks on the beaches.These batteries are really good they have never let me down as of yet, that's why I will be getting more. All I can really say is byem.
  
  
• Good product!
  By A2AJAAKLIGYAFJ on 2007-09-10
  I find this product accidentally in Amazon. I bought it and came back to Amazon to buy more. It is no longer available.
  
  
• Great Batteries
  By AVJYK96OVH9AP on 2008-06-04
  Between these and the Powerex batteries I cannot tell the difference. Both are problem the best rechargeables on the market. Last long retain charge well when not in use.
  
  
• Good Buy
  By A21GPXDD6B2G7J on 2008-06-15
  These Batteries are excellent.They hold the charge the way it is suppose to be.I am very satisfied. Buy them. It's worth the money.
  
  
• Really delivers close to 2700mAh
  By AI5EIS34J73QB on 2008-07-27
  The BC-900 recharger indicates that the batteries delivers nearly 2700mAh. This is far better than all of the other batteries that I have bought.
  
  I bought 4 packs for my Nikon flash units and it seems that the flash unit is ready for another flash much quicker than other batteries.
  
  Buy the BC-900 recharger when the price is about $39. It really is worth it.
  
  
• Best on the market
  By A3VZGZ341VYCJP on 2008-02-26
  I have tried numerous brand of AA's for ham radio and photo use and these Sanyo's last the longest and hold the longest charge per use. Well worth the cost and of course Amazon's service excellent as always.
  
  
• Product as specified
  By A31T2HI8SX0D39 on 2008-04-19
  These were purchased as replacement batteries for a camera I will be selling ... and have found other good uses for. They were as specified in the product description.
  
  
• simply the best.
  By A2RGC2RNQ6YXDY on 2008-05-22
  These are by far the best rechargeable NiMH batteries I have. I use them mainly for my guitar effects board and they run at least twice as long as any of my other NiMH batteries.
