Product Description
From the Manufacturer Why Sanyo eneloop? Sanyo eneloop rechargeables can replace an entire kitchen drawer’s worth of dry cell batteries You already know the benefits of using conventional rechargeable batteries. But Sanyo eneloop batteries have advantages over other rechargeables that put them a step ahead. Sanyo eneloop batteries are an excellent choice for your rechargeables because: * They can be used right after purchase * They consistenly yield high performance * They have a long shelf life with no loss of energy * They can be used everywhere * They are environmental friendly Self-Discharge: Why Conventional Rechargeables Don’t Cut It Conventional rechargeable batteries have numerous advantages that make them great to use for your portable electronics. But they also come with certain disadvantages. After purchase, rechargeable batteries have to be charged before they can be used. And once charged, rechargeable batteries lose the stored energy rather fast. The charging takes quite long and rapid chargers are expensive. Not only that, but continuous charging or frequent charge to “top off” the lost energy (without complete discharge) can destroy the battery. All these negative attributes have one root-cause: self discharge. Self-discharge means that a charged battery slowly discharges itself without any equipment consuming any current. This is the reason for rechargeable batteries being sold in a discharged state. And this is the reason that keeping charged batteries for some time did not make any sense. When you needed them, the energy was gone. Sanyo eneloop batteries have an extremely low rate of self-discharge, which means they hold their stored energy for a very long time–charge your batteries once and put them in your kitchen drawer, and over a year from now you’ll still be able to use them right away, without needing to charge them again.

Sanyo Eneloop 8 Pack AA NiMH Pre-Charged Rechargeable Batteries Review
Based on reviews on other Eneloop products, I bought this kit prior to my vacation. On the whole, I’m quite pleased. It’s only been a month, but the batteries seem to be holding their charge fairly well. Certainly, they’re doing worlds better than my old ones which had the camera showing a low battery warning after an idle week. The charger is fairly slow. You’ll want to leave your batteries in it overnight rather than trying to top them off in a hurry. Note that the charger can only charge TWO batteries at a time. I didn’t realize that when I ordered it and was disappointed. It’s also kind of finicky to get the AAA batteries into it. The AA’s went in nicely.

A friend in Japan sent me some eneloop cells when they were first introduced. They tested out very close to their rated capacity of 2000 mAh. I then conducted some self discharge tests. I fully charged the cells and set them on a shelf in my house. I checked them at 30 days, 90 days, and 180 days. After 6 months of room temperature storage they had 86% of their initial capacity.

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!

Sony BCG-34HRMF4 Battery Charger Review
The charger seems to charge the batteries as it is supposed to. It takes about 8 hours to fully charge four batteries. Once charged, the batteries work OK if used within a couple of days, although I thought I would get more pictures per charge than I do. The real problem is that after about 5 days after charging the battery, they are essentially dead. They will not even turn on the camera. It doesn’t matter if they are stored in the camera or not. The voltage measured at that point is about 1.1 volts. I have had the unit about two months and this has been a problem from day one. I even tried a full discharge through the charger, but that made no difference. I don’t know if I have defective batteries (all four) or if the charger is not providing a full charge even though the indicator shows it to be fully charged. expected better from Sony than this.

I’m using these batteries for my Xbox 360 controllers and they work great. Charge up overnight and they last for about 3 weeks or longer. My electric razor has lasted for over a month without a recharge of the batteries. It simply does as advertised. Fair price/works great. I liked it so much I had to buy another 4 pack of batteries for it (comes with 4). Give it about 7 hours to charge. I pop the batteries in over night and it cuts off automatically after they are charged. Charges AA & AAA. LED indicator is a nice touch.

The refresh function is very helpful. And if you not in a hurry, just let the batteries in the charger, they will not be over-charge. No hot battery, and you can charge one/two/three or four batteries at the same time as you wish. The Sony batteries in the package is also in good quality, and super powerful.

Love this charger! You can charge individual batteries, in case you have something that requires 3 or 1 which is really useful. I charges fairly quickly but do not expect it to be 10 minutes, but I have no rush since the SONY batteries last so long. I have a Nikon Coolpix P50 and I took and reviewed almost 1000 photos and a video with a single pair of batteries and only use the second one when I needed to copy the photos to the computer. The feature of that display with the exact charge of each battery is wonderful, used it even to measure some already charged batteries.

So far I am very pleased with this product. I use AA batteries in my sb600 flash for wedding and other portraiture and the batteries stayed juiced up and ready to go instantly for the duration of the wedding. I wish I had thought of doing this sooner, it would have saved me a lot of money and stress keeping full batteries in my speed light. The unit is small and light and has universal voltage which was a big selling point for me as I see travel in my future. The automatic shut off is nice too so you can juice up over night while sleeping and be ready to go the next day. My only wish is that it would accommodate 9 volt batteries but I guess you have to pay a higher price for something like that…..Overall very pleased.

Sony 2500 mAh AA Rechargeable Nimh Review
These batteries are the longest lasting rechargeable batteries I’ve ever had for a digital camera, and rival the life of lithium batteries. They last for well over a hundred shots with our Canon S3IS, as well as reviewing pictures and playing around with settings, etc. Great batteries for a great price.

These are my first rechargeable batteries, so all I can say is that in comparison to alkaline, these are WAY better and longer losting. Alkalines stop working in digital cameras long before they are actually used up, because they can’t supply the required current for high-demand devices. These Sonys last much more than 4x as long because alkalines only work for a few minutes. These Sonys maintain their voltage at a stable level. I am using them in an Olympus C-755 digital camera, and I charge them using the Sony BCG-34HE4 charger. I can’t say exactly how many pictures you can take on one charge, because they last for so long I lose track. If you have a digital camera, you absolutely must use rechargeable Nimh batteries. Don’t waste your money on the expensive “high-end” alkalines or non-rechargeable lithium, etc. Also, you are doing the environment a favor by not using toxic landfill filler.
