Excellent battery, fair price
April 12, 2014
I got some of these batteries for various emergency situations. As well as using them to run bicycle headlights--and not the wimpy sort, either. The lights I now run are far brighter than mainstream lights, but use more power. In below zero (-20 C) conditions, I experienced no major issues with these batteries while running them.
Additionally, they hold their charge. After storing them for a year in devices used for emergencies, I top them off. And it only takes a few minutes, indicating that they are still mostly charged. This yearly ritual sure beats running to a store in an emergency, fighting a crowd, and paying too much for the last batteries that may not get through the emergency. And, when used in the Fenix headlamps (sold here), it matters not whether the lights go out (and the generator goes dead) tomorrow or next year, or several years from now. These batteries will be ready when I need them--beats trying to work in pitch dark or being at the mercy of the store to supply flashlights (which are usually wimpy).
They also work in other devices where alkaline batteries used to be required. About the only devices they do poorly are those Christmas lights that require 1.5 V and do poorly at 1.2 volts. Otherwise, they are fine--and no issues with charging with the smart chargers sold here. Saves money on alkaline batteries, prevents them from ending up in landfills, and no leaks! No leaks means no ruining that expensive O-light or Nitecore light. It also means having power when you need it.
Pros:Rechargeable for more than 1,000 recycles, or more than 2-3 years in heavy use.
Holds a charge for any emergency situation, whether now or a year from now.
You can charge more than 100 of them and then be ready for an emergency instead of wasting time at the supermarket.
Cons:Reduced capacity compared to standard NiMH batteries, but that's what you get for low self-discharge.
The voltage of 1.2 volts may not work in all devices, especially incandescent lights, unregulated flashlights (the cheaper ones), and certain Christmas lights where 1.5 volts is mandatory. This is true with all NiMH batteries.
