Digital camera reviews of Sanyo 2,700 mAh AA NiMH Rechargeable Batteries (4-Pack)
Digital camera Review: Outstanding Capacity - Great Quality
Summary: 5 Stars
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.
Digital camera Review: Sanyo 2700 mAh - one of the best
Summary: 4 Stars
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, 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.
Digital camera Review: Long lasting for an excellent price.
Summary: 5 Stars
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.Digital camera Review: * Best rechargable AA to date
Summary: 5 Stars
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.
Digital camera Review: AVOID "Eneloop" - buy these instead
Summary: 5 Stars
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.
