No Memory Effect Capacity Loss - Recharging a Ni-MH battery before it has been fully discharged will not reduce the storage capacity of the battery.

No Over Discharge Leakage - While Alkaline batteries will eventually leak when over discharged, Ni-MH batteries will not.


Over Discharge - If a Ni-MH battery is over discharge it might not be able to be recharged.

Over Charging - If a Ni-MH battery is over charged or charged too fast, it may over heat and trigger a safety built into the battery (such as a pressure release valve or charge connection) that will render the battery useless. Most chargers have measures to prevent over charging and over heating of Ni-MH batteries.

Do not expose any batteries to flame or other extremely high temperatures.

Do not store batteries in direct sunlight.

  1. Better than certain copper tops. Review Rating

    I use these in my power house flashlights. I get maximum output capability with these ones for longer than with regular batteries. While they may be a bit more than regular batteries, they are cost efficient in the long run as they are rechargeable. I recommend these for those who have power house flashlights and use them a lot like I do.
