Digital Cameras Photo Reviews of Sanyo Eneloop AA NiMH Pre-Charged Rechargable Batteries with Charger - 4 Pack
Customer Review: Work fine, but drain fast
Summary: 3 Stars
It is good that these are rechargeable, because they are draining fast. I go these for my Apple wireless keyboard and mouse. When they arrived I went ahead and fully charged them, just for good measure. The day I started using them, my computer reported both devices as having 81% battery charge remaining (this was right after the charger said they were fully charged). They have been in use for close to 3 weeks now, and they report as being 58% charged. Note for comparison the standard Energizer batteries I had in these devices before lasted for about 10 months before dropping below 20% charged.
It will be interesting to find out whether these batteries hold less of a charge and drain faster, or if this is all just a reporting problem caused by the difference between rechargeable and regular batteries.
Customer Review: Great!
Summary: 5 Stars
I am using these with my Zoom Q3 HD Audio / Video recorder, and battery life has improved dramatically as compared to Duracell AA batteries:
Standard AAs: ca. 4:20 h of audio recording (AAC 320 kb/s)
Eneloop: ca. 6:30 h of audio recording (AAC 320 kb/s)
Almost sounds too good to be true but that's what I am experiencing - and testing is simple: I recorded with a fresh set of batteries / fully charged Eneloops, by the time the recorder shut down and saved the file I had a good approximation of the battery life => the length of the audio file the Zoom saved before it shut down. :-)
I'm glad I bought these, great design, works as described (charging takes several hrs for a full cycle - I do it overnight) and it saves me tons of money on batteries.
Customer Review: Excellent batteries with good charger
Summary: 4 Stars
Have had good experience with Sanyo enelope rechargeables, and decided to get this to use in my Pentax DSLR as these were the most recommended of rechargeables for the camera. The batteries hold the charge well, and the new charger is a welcome improvement to my 3+ year old Panasonic charger. The new charger is able to charge two batteries as seperate set, compared to my current charger which charges all four as one. There is a more slimmer model charger made by Sanyo which is capable of charging each battery independently but the charger only works with 110V which does not make it a great travel charger, which is why I opted for this charger as universal compability in voltage was important to me. Note though the charger is not a quick charger, and takes a few hours to charge a set of batteries.Customer Review: Convenient and reliable
Summary: 5 Stars
I use these in my Canon 430EX II flash unit, and they work great. Recycle times are really quick. I don't know exactly how many shots a single charge is good for because the most I've done in a single session was around 400 shots and the batteries were still going strong.
Sanyo eneloop batteries lose their charge much more slowly than regular NiMH batteries, so I don't have to bother charging them again just before using them. This isn't an issue for those who shoot photos all the time, but I don't use my flash every day so this is a nice benefit.
The charger is reasonably fast. It takes 3 hours to charge 4 batteries. Chargers that are quicker than that usually put too much strain on the batteries and decrease their lifetime. It can also charge AAA batteries, which is nice.
Customer Review: Only rechageable batteries I'll ever buy
Summary: 5 Stars
I own an Olympus C-3000 digital camera, and found that regular batteries were inadequate, would drain completely after only a few photos. After reading the reviews on Amazon I decided to try Sanyo Eneloop batteries - now I am completely sold on them! They last about a month in my camera, even with the hundreds of pictures I take, and recharge in about six hours (I suspect they will keep their charge for months if I don't use the camera, but I use the camera frequently so I've never tried that). I also like the charger - green LEDs blink while the batteries charge, and stop blinking when the charge is complete. I was so happy with the batteries I bought another set for my dad's digital camera (also an Olympus C-3000). I would recommend these to anyone, despite the funny name they are the best!
