Thread: When is long enough

    Default When is long enough

    what is considered an exceptable time limit for leaving primary CR123's in your lights while sitting on a shelf waiting to be used? would that time limit also hold true to RCR's?

    Welcome! Just to give you a heads up, the moderators will probably move this to the Flashlight Electronics forum.
    CR123 are lithiums so they have quite a long shelf life. I think after 10 years they still have 85% of their capacity. They are also more tolerant of extremes of temperature. They should be OK to sit in a light for quite a while. If you have a multi cell light it is important that the voltage of the cells match otherwise you can run into problems like venting with flame. If you do not have a volt meter and if if you have a multi cell light I think it would be a good idea to store the light without batteries in them. Single cell lights are fine though. With regrad to RCR123's they can retain their charge for quite a while, I think I read up to a year. For the health of the cell it is better to store them at around 40% if they are not going to be used for a while. I think the safest thing to do is store CR123 batteries by themselves and use the RCR123's for day to day use.

    I'd rather have it and not need it than need it and not have it.

    Well,Primary Batteries have a 10 year shelf life.

    I would be sure to test the batteries every 6 months or so.

    Otherwise: <10
