Like everyone else these days I have a lot of devices and products that require batteries: wireless keyboards and mice, remote controls, digital cameras, clocks… the list goes on. With all these battery-hungry devices, purchasing non-rechargeable batteries just doesn’t make financial sense anymore. Rechargeable batteries are nice, but most rechargeable batteries rapidly lose their ability to hold a charge after a few dozen charging cycles. Traditional rechargeable batteries also can’t be stored for very long without losing their charge.

A little over year ago a product called “Eneloop” by Sanyo came to my attention. The buzz over these batteries was really strong, and after reading a bunch of positive reviews I purchased a full kit with a charger.

One year and hundreds of charges later, I can say without hesitation that these batteries are incredible. They are far better than any rechargeable battery I’ve used before. The Eneloops have definitely lived up to the hype.

Eneloops do not suffer from memory effect. You can recharge the batteries at least 1,500 times with zero reduction in power from one charge to the next. They also have extremely slow self-discharge. In other words, you can toss a fully charged set of batteries in a drawer somewhere and 3 years later they’ll still have 75% of their original charge. I have not had the batteries long enough to test that claim (others have, however), but the other day I pulled out a set of AAA Eneloops that have not been touched since January 2010 and they are going strong.

If you’re frustrated with regular rechargeable batteries then pick up this kit. You’ll be very happy.

The kit comes with a charger, (8) AA batteries and (4) AAA batteries. Of course you can purchase more batteries (including C and D adapters) on Amazon.
