Was an Energizer distributor from 1990-2005. Could purchase Alkaline AA batteries for .25 cents each. Retired now and get sticker shock every time I purchase Alkaline batteries retail! The Ni- Cad style rechargeable batteries were just not practical to use. They would not hold a charge in storage and needed to be charged before each use. These newer Metal-Hydride batteries come fully charged and will hold the charge till you need them. (Approximately 1 year) Game changer, Game over, Metal Hydride batteries are great! Read more

Awesome! Repeat purchase. I use these with an Opus BT-9100 charger, and these are my go-to batteries for almost everything. They last - both in each use, and over recharge after recharge. Pro tip: charge as slowly as you can for the best overall battery life. I’ll use 200mA/h if I’m not in any hurry, 500mA/h to speed things up, and rarely to never do I need 1,000/2,000mA/h recharging rate. Note that the NI/MH chemistry provides .2-.3V less than standard batteries, which works fine for almost everything I use them in. Yes, flashlights would be slightly dimmer for example, not to the extent I can even tell. To not buy countless disposable batteries I’m totally okay with that! Most devices that have a battery status indicator will show these as not 100% full also due to the lower voltage. These batteries handle high current demands very well (flashlights), and good overall life for slow drain devices (remote controls). I’ve been using some for years, only buying more as my needs increase. Even after years, I’ve not had to retire even one of these batteries! Read more

These batteries are definitely use it or lose it items bought a 4 pack with a charger about 8 years ago, only charged once & then set in a drawer. Were unable to recharge. Hopefully I’ll have better luck with these new ones. The price on the new ones are a lot better. I’ll try some AAA… Read more

Great product. Stopped using Deracell because I didn't like the performance. Quick delivery, package, and product were not damaged in shipment. Read more
