As is, you’re probably better off spending a few extra dollars on a smart charger so that you’ll get more rechargers per battery, which will save you more money and energy in the long run.
Should you buy the Energizer Recharge Value AA/AAA NiMH Battery Charger? I wish that it was a smart charger with the capability of not over charging each individual battery because I really like this charger for the main two reasons I mentioned above: easy battery removal and large status LED. That doesn’t mean the batteries will explode or catch fire, but it can negatively impact the overall life of the batteries. If you forget and leave them in the charger until the auto timer turns off after 11hrs, those batteries will be over-charged by over 50%. When you use it to recharge the included 1300mAh batteries, you have to remember to remove them after 5-6 hours (because 1300mAh/300mA = ~5.5 hours). No matter what the actual capacity and status of your batteries, it will charge for that length of time and will then turn off. The Energizer Recharge Value Charger charges at a fixed current (300mA for AA, 150mA for AAA) for a fixed time of 11 hours. This usually results in over-charging which is bad for battery lifespan. A Dumb charger relies on a timer to stop charging or has no termination mechanism at all. What’s the difference and why should you care? A Smart charger monitors the voltage of each cell individually during charging and stops when a charge-termination signal (negative delta-Voltage) is detected. It’s actually a timer-based dumb charger. It’s important to note that this is not a smart charger. As luck would have it, I didn’t have any other brands of batteries to test.But the charger should work just fine as long as the batteries do not exceed 2650mAh for AA’s and 1000mAh for AAA’s. The other feature that I like is the large status indicator, which glows red while charging, green when finished and flashes red when a bad battery has been detected.ĭuring the time that I’ve been testing this charger, I’ve used it to charge the included batteries as well as another set of Energizer AA’s that I already had on hand.

When the folks at Energizer asked if I would like to review one of their chargers, I gladly accepted and they sent me a sample of their new Recharge Value AA/AAA NiMH Battery Charger. I’ve been using an ancient Realistic (Radio Shack) branded charger for years and although it charges batteries just fine, it’s bulky and not efficient because it continues to charge the batteries even after they are fully charged. How many devices, toys and gadgets do you own that use AA or AAA batteries? Do you feed these devices standard alkaline batteries, or do you use rechargeables? I personally prefer to go the rechargeable route mainly because it’s easier and less expensive for me to pop a set of drained batteries into a charger and wait for them to rejuice, then it is for me to drive to the store and buy a brand new set.
