    Hi All,

    I am using a Lithium Ion battery, the Sanyo UF103450P, in a back-up
    application where it is nearly never discharged and topped up once every
    couple of months when it needs it (dues to self discharge)... My question
    concerns the operating temperature. Every now and then the temperature can
    creep up to 45C and during the summer, on hot days I expect it may get a
    little warmer and I worry about what would happen if the temperature exceeds
    60C, its maximum rated temperature during discharge (for some reason it
    only has a 50C rated storage temperature?). Is it likely to be unsafe or
    will it just shorten the life of the battery over the long term? I monitor
    the temperature during charge/discharge, so am only worried about it during
    when it is sitting idle.

    Any comments are as always, greatly appreciated...

    Best regards,

    To even begin thinking about solving the problem i would need all of
    the patented and trade secret data on the battery. Oh, and i might
    have to go get a PHD in chemistry along the way, on your dime. Of
    course, you could try pestering the manufacturer until they geek the
    data you need.
