Best way to store NIMH and Lion batteries?

    What is the best way to store NIMH and Lion batteries? I am thinking
    about long term storage for many years. They will not be used during
    storage. Is it better to freeze them? Should they be charged or
    discharged before storage? Do they need periodic attention, such as
    recharging or "renewing"? How can I make them last as long as
    possible?

    TIA - Tom

    No matter what you do, they will chemically degrade. The max shelf life is
    about 2 to 3 years. Freezing them, infact may cause some internal corrosion
    and damage over the long term.

    2-3 years? I have some that are older than that and still working fine, but
    then they get somewhat regular use.

    Are you suggesting that it would be better to use them than to store
    them?

    Thanks to you and Jerry for the replies.

    The ones in solar lights seem to degrade after about three years of
    use, but in storage, NiCd last decades if they don't corrode. NiMH can
    sometimes get a pseudo-memory disease if used after long storage which
    goes away when they are correctly cycled a few times (loss of
    capacity). This is always advisable with Nixx cells - a simple
    capacity meter may be built from a clock and 2.5 ohm resistor
    (www.repairfaq.org)

    If the cells have the white powder disease this may not be terminal,
    clean off with solvent of your choice on cotton bud then distilled
    water (vinegar seems to work) and test, they usually work fine. Dry
    properly before use!
