Digital Cameras Photo Reviews of Sanyo Eneloop AA NiMH Pre-Charged Rechargeable Batteries - 8 Pack
Customer Review: Best rechargeable AAs
Summary: 5 Stars
Over the past few years, I have tried a lot of rechargeable AA batteries. The eneloop ares my favorites by far. I have even tried other brands of slow discharge types, and found them to run out of "juice" faster, despite similar mAh ratings. My only theory is that Sanyo has figured out better than their competitors how to create a battery that discharges more slowly when not in use. The mAh rating of these batteries is confirmed by my LaCrosse charger at around 2.0.
I knocked the Durability score one star only because these batteries seem to last the longest straight out of the package. After their first charge, they seem to require charging a little sooner. Still, they are better than what I have observed with other rechargeable batteries. They are a little more expensive than many other brands, but because they last so long each charge, and come back again and again, they are actually an excellent value. Plus, I'm glad to be doing my small part to help the environment by reducing my battery waste (which would otherwise be significant, considering all the toys and Wii remotes used by my 3 kids!)
Customer Review: Great batteries, great price
Summary: 5 Stars
I bought a total of 7 8packs and am very happy.
NiMH batteries are great in that they hold more total energy than an alkaline cell, and they can be recharged many times with out memory affects. The traditional drawbacks of NiMH is that their voltage is 1.2V as apposed to 1.5, and that they "self disscharge" which means that they go dead on their own.
Hybrid NiMH like these eneloops and the Hybrio cells solve the self disscharge issue. The total stored power in the cell is less than a traditional NiMH (hybird=2AH while traditional NiMH=2.7AH, and alkaline typically has about 1.5AH) but for high drain devices like a digital camera, these are absolutely the BEST.
In my digital camera, which takes AAs, hybrid NiMH are the only ones that work. Alkaline cannot keep up with the load, and traditional NiMH are dead after a week. These Eneloops last for months.
If you are some one that wants to try rechargeable batteries, I would reccomend paying the extra money and getting hybrids like these. They are much more functional than the other NiMH, and the price listed here is very low.
Customer Review: Simply Awesome.
Summary: 5 Stars
I always hated NIMH batteries because they lose their charge so fast. I have 20 year old NiCad rechargeables that work better. However, neither type stands up the new "low self-discarging" (LSD) NIMH batteries that Eneloop has popularized. I installed Eneloops in both my Wii Remote and Balance Board. They have held their charge over six months now and have worked flawlessly throughout this time. According the Wii Remote I still have 3 of 4 dots of power left.
I also have two AAA Eneloops that I installed into a Harmony Remote Control. Because the remote takes four batteries I also installed two new alkaline batteries. The alkalines have already wore out and need replacement yet the Eneloops are still going strong.
If you need batteries, just get these and you won't be disappointed. If you don't already own a battery recharger, the so-called Sanyo 277265 Eneloop Power Pack with Battery Charger, 8 AA & 2 AAA Batteries Plus 4 C & 4 D Size Adapter (CostCo Kit #2) is a good place to start.
Customer Review: Nice Surprise
Summary: 5 Stars
I'd never purchased rechargeable batteries before, since they typically had a poor reputation. My belief was that the batteries did not hold a charge for long. So why bother?
Well, the Sanyo Eneloop rechargeable batteries are not what you'd expect based on the reputation of these earlier models. They come charged, right out of the package. I recently bought a Tivoli Songbook and decided to use rechargeable batteries to conserve and avoid throwing away standard batteries every few weeks. The Sanyo Eneloop batteries lasted for about 2 weeks with their initial charge (i.e., out of the package). They quickly recharged when the radio was plugged in, taking about 4 hours (to fully recharge). This and the subsequent charges have lasted for about 2 to 3 weeks each time, with average usage of the radio (about 3 hours per day).
Overall, I'm very pleased with these batteries. In addition to being environmentally safe, these batteries will save me a significant amount of money over time, by not having to buy (and then dispose of) 6 alkaline batteries with each replacement.
Customer Review: what a relief! finally rechargeable batteries that last!
Summary: 5 Stars
After having to recharge or swap out my rechargeable batteries for my kid's toys, my remotes, my clocks, and especially my pc's mouse way too often (almost daily with my mouse it seemed) I finally got my hands on these eneloops. And they're going to replace all my other rechargeables!
The toughest test of charge/use time is my mouse: the eneloops have kept it going for daily 8-12 hour use for almost a week and a half so far. That far exceeds the length of use I was able to get out of non-eneloop 2700 mAh rechargeables that I was using just prior to these.
I should say that I'm not the best rechargeable battery user: I had a habit of recharging the rechageables BEFORE putting them into STORAGE rather than use. I've read that that's the best way to shorten the life of a rechargeable battery - dumb me. So, anyway, my enthusiasm for the eneloop's longevity while in use may be a bit skewed by my potentially prematurely killing my previous rech. batts but, still, just based on non-metered personal use, I find these eneloops to be very strong out of the box.
