Digital camera reviews of Sanyo Eneloop AAA NiMH Pre-Charged Rechargeable Batteries (4 Pack)
Digital camera Review: Beats Duracell Pre-Charged and Rayovac Hybrid
Summary: 5 Stars
I recently bought Duracell Pre-Charged and Rayovac Hybrid batteries from Wal-Mart. I fell in love with these batteries because they do not lose their charge quickly like other rechargeable batteries, but when I went back to Wal-Mart to buy more, they apparently decided to discontinue offering them. So I searched the internet and found that Eneloop was apparently the original "hybrid" or "Pre-Charged" battery, so I decided to give them a try. I fully charged the Duracells, Rayovacs, and Eneloops and I put them in the same same exact flashlight model and I tested them. The Eneloops lasted much longer than either the Duracell or the Rayovacs, so I have decided to replace all my old rechargeable batteries with Eneloops. I feel that Wal-Mart has missed the mark by apparently discontinuing to offer this new class of batteries. Oh well, their loss. I actually found a better battery at Amazon . . . the Eneloop. You had better watch out Wal-Mart! With the high price of gas, maybe everyone will be buying these batteries from Amazon because of the free shipping. Exxon and Texaco had better watch out too. Not only will we be driving less, but if we can find a way to run our cars on these batteries, they will be losing even more business. Don't laugh. It costs only $3.00 to charge a Tesla Roadster. It goes 0 to 60 mph in about 4 seconds and it runs on battery power without a drop of gas. It is time for companies like Amazon and Google to take charge of America's future! The old way of doing business in this country is over! If traditional companies will not embrace new technologies like the eneloop, then it is time for other companies to take over. Perhaps in the next few years, these batteries will be re-charged by power generated from the sun, wind, and water. Plug-in hybrids like the Chevy Volt could make the gasoline powered Toyota Prius obsolete. I guess you get the point. I really like these batteries and what they could possibly do for our future. Buy them from Amazon. You won't regret it.Digital camera Review: Best Batteries Ever
Summary: 5 Stars
These batteries are the best. I will never use any other type. They hold a charge better than any other rechargeable battery I have ever usedDigital camera Review: Best Batteries Yet
Summary: 5 Stars
These batteries are great. First, they tend to hold a higher mAH than they are rated. Slow self discharge means they are not dead after 30 days of sitting like traditional NIMH(Sanyo says 85% life after 1yr!). The only downside is if you have a large series of them, used in a voltage critical application. ALL NIMH ONLY HAVE 1.2V compares with alkaline 1.5V(alkaline Voltage drops to 1.2 after about 60% life). This is most notable in a large series of them, and the .3V drop is cumulative. This is not a fault of Eneloop, this is the case for all NIMH AA's or AAA's. Again though, best consumer AA or AAA yet.Digital camera Review: Best Battery

Seems to be about the best rechargeable battery available. Haven't had them long enough to attest to their duration, but so far, so good.Digital camera Review: Best In Class
Summary: 5 Stars
These were the first "low discharge" (i.e. long shelf life) rechargeable batteries on the market and they're still among the best. My tests, and those of others, confirm they hold a charge longer than competitive batteries, and typically exceed their rated capacity. The only batteries I've found that come close are EnergyON but they're about the same price and I prefer the Sanyo version.
In devices the use very little power, like remote controls, typical rechargeable batteries die of their own self discharge long before they otherwise would. Many NiMh and NiCad batteries lose as much as 15% per month. So even fully charged, they're dead (or nearly dead) in 6 months just sitting in a drawer.
These Eneloop batteries, however, only lose a few percent a month. So they can last a year or longer in something like a remote control before you need to charge them.
If you have a high-drain device like a camera flash or flashlight, that you use often (several times a month) these batteries will offer little benefit over regular NiMh cells. But for devices that you don't use often, or use very little power (like a clock or remote control), they're BY FAR the best choice.
