Recharge Your Alkaline Batteries Several Times

January 8, 2013

Single use AA and AAA Alkaline batteries are some of the most plentiful, expensive, wasteful items on the planet. We pay upwards of a buck each, use it only one time and toss it in the trash or recycle bin. Either way it’s a wasteful nightmare with countless BILLIONS of these batteries littering our landfills.

Imagine the savings to your wallet and reduced impact on the environment if you could recharge them and use them several times before sending them to the recycle bin?

A well kept secret is that Alkaline batteries CAN be safely recharged. Now some of you’ve heard that they will blow up and take grandma with them. If you use a NiCad or older style charger, you could have a problem. However, technology has finally found a way to SAFELY and efficiently recharge Alkaline batteries for almost nothing.

The newest generation of smart chargers are so affordable; they pay for themselves almost immediately in battery savings.

Our unit cost around twenty bucks, and will charge a single AA or AAA battery, or up to four at a time. The whole process is simplicity itself. You put the discharged battery in the unit (it only fits one way) and immediately it will read red for charging, green for charged or no indicator for dead.

A microprocessor monitors and controls the entire process including the temperature. It charges for about four hours at a slightly higher voltage to refresh the batteries. After they are “topped off” they go from red to green and can remain in the charger without damaging them.

To test our Rosewill CT 505 charger, I retrieved over fifty batteries from the recycle bin at a local store, all brands, all states of discharge and from all types of devices. To my surprise, I found that almost 10% of them were still good, probably taken out of a bad device or replaced prematurely. About the same amount were worn out and couldn’t be recharged. The balance were in various states of discharge and were all successfully recharged.

Since my test, I’ve recycled hundreds of batteries, some several years old without a single problem, and given them away to family and friends to be reused with the condition that they return them for fresh ones. Nothing says I love you like a fully recharged battery.

Tell your friends to save their old ones, and you can retrieve them from recycle bins (with permission of course) if you want to have a supply on hand.

Devices like remotes, LED flashlights and MP3 players work great with recharged batteries and the difference between a new one and recycled one is very slight. When they get so depleted they don’t take a charge, go ahead and recycle them.

It’s estimated that Americans dispose of 160,000 tons of single use batteries each year.

Imagine saving big bucks on batteries and easing a big burden on the planet at the same time – talk about a win – win. For more information go to: or contact

    Dang! That’s good to know! We don’t go through a ton of batteries, but my kids tend to go through a few. I’m going to have to give this a shot.

    To be clear, are you saying the newest NiCad chargers will do this or is there another type of charger you are describing? Thanks

      A nicad charger will NOT work. The charger I’ve been testing is a Rosewill available on Amazon
