  • NiMH batteries pose less threat to the environment as they do not contain the heavy metal cadmium
  • May be charged up to 1,000 times for years of battery power; use only NiMH rechargers
  • Charge before use


Help keep harmful heavy metals out of our air and water by recycling your rechargeable batteries. For information on how you can get started recycling rechargeable batteries, visit the Rechargeable Battery Recycling Corporation website at

Rated 1 out of 5 by from You get what you pay for I purchased several of these batteries last year in order to power a water pump, a radio, a tent heater and a flashlight that I take with me on camping trips. I was in need of rechargeable batteries to power these pieces of equipment so that I could avoid wasting money on one time use only alkaline batteries. Along with the batteries I also purchased the Energizer universal NiHM charger. After just a few uses I was extremely disappointed with the overall performance with these batteries as well as the charger itself. For starters, the batteries took a ridiculous 16 hours to charge completely. Once charged, these batteries powered my various pieces of equipment for only a fraction of the time when compared to the alkaline batteries I was previously using. My Sony CD player has a rated run time of 4 hours on cd play-back mode, however it lasted approximately 1.5 hours off of a set of fully charged Energizer NiHM 2,500 mAH D batteries. I later realized that I had blindly purchased D batteries that were greatly underpowered when compared to other rechargeable NiHM D batteries that are on the market today. In comparison, many of the AA rechargeable NiHM batteries on the market today are equal in power, if not more powerful than these much larger D cells. I also found out that these Energizer batteries are not actually D batteries at all, but are in fact C batteries wrapped with a D shell to make them larger. This explains why these batteries are so light weight and underpowered. For only a few dollars more per battery I was able to purchase 10,000 mAH D cells which last much longer in my portable electronics. Otherwise you will find your electronics dying often and recharging these batteries frequently. I highly recommend avoiding these batteries and investing a few dollars more in a higher quality charger and better batteries with a higher mAH rating. You will be glad that you did.
