Sanyo Eneloop Batteries Review
I bought these batteries for use with my Canon S2 digital camera. I was having trouble with typical nimh batteries because I would charge a spare pair of batteries for use when the main pair died. But I was finding that the ones I charged a few weeks ago would be almost fully discharged by the time I would swap them. This was really annoying and pretty much defeated the purpose of having rechargeables… I had to use alkalines instead. But this new so called ‘hybrid’/low discharge technology finally solves this problem. Of course it does not solve it completely because these batteries still discharge over time… just a lot slower, but at least now I know I have a pair of batteries that are at least 80 percent or so charged when I swap them. This technology was actually developed by an small independent company and licensed for use with all the major battery companies now. For instance, Sony is also utilizing it in their new batteries now. To me, this demonstrates how well it works. So how does it hold up in real life? Pretty darn well, actually. I noticed that these particular batteries last really long in my Canon S2. I haven’t had the problem of charged batteries being totally discharged by the time I swap them anymore. So if you’re having similar problems with your older Nimh batteries, I would recommend giving these batteries a try. But don’t feel limited to this brand, there are many other brands utilizing this technology and I’ve used other brands with the same great results.

After switching digital camera from Canon A75 to A540, I discovered the battery life is extremly short on the A540. At first I thought it’s because Canon A540 uses 2-AA instead of A75 with 4-AA batteries, then one time, after taking ZERO pictures and freshly recharged NiMH sitting in the camera for only one day, the “low battery” indicator came on. This happened to both Energizer NiMH 2300mAh battery and Sony NiMH 2600mAh. So I begin to Google the problem and discovered it has something to do with rechargeable battery’s drop-off voltage characteristic and how Canon’s camera interpret this as low battery indicator. Hence comes the Eneloop. These batteries’ voltage doesn’t drop and they discharge very very slowly. I have used the Eneloop for over two months now and glad to say it finally solve the problem of my Canon A540. A set of freshly charged Eneloop can last for weeks and 300+ pictures and counting. Plus the charger is 110v to 220v capable, so my trip to Asia/Europe won’t require a different charger. This is an awesome product and I will buy more of it!

I have a 5 MP digital camera that only uses 2 AA batteries and was getting very finicky about the Energizer and Rayovac rechargeable NiMH batteries I supplied it with. I like to charge up my batteries and keep a spare set in my camera case for backup. However, I was continuously putting in the fresh batteries and the camera wouldn’t even power on. It would say “Change batteries”. It was baffling b/c batteries that were totally charged were not working any more. The only thing I could figure is that because NiMH AA batteries are only 1.2 Volts instead of the standard 1.5, anything less than a full charge would not supply the camera with a high enough voltage to power on. Then I started reading about batteries and discovered that these things lose charge surprisingly fast when sitting in storage. I bought four Eneloop batteries and tried them. I have been amazed at the performance with my digital camera. With the previous brands of NiMH, I could maybe get 120 pictures from the camera. Now I can go almost double that time. Don’t ask me why. Part of that reason is probably due to the fact that I don’t use my camera for significant amounts of time between shoots. So the eneloops hold that charge MUCH better. Anyway, foot the extra cost of these batteries and order plenty of extras. You’ll be glad you did when using high-drain devices!
