    Forgive me if this issue has been discussed b4, but i was wondering, if i am going to be putting my storm up on a shelf for a few months, is it better to allow the battery to drain completely, or should i keep charging it periodically?
    thanks for answering

    Lithium-ion battery - Wikipedia, the free encyclopedia

    Storage temperature and charge

    It is significantly beneficial to avoid storing a lithium-ion battery at full charge. A Li-ion battery stored at 40% charge will last many times longer than one stored at 100% charge, particularly at higher temperatures.[27]

    If a Li-ion battery is stored with too low a charge, there is a risk of allowing the charge to drop below the battery's low-voltage threshold, resulting in an unrecoverable dead battery. Once the charge has dropped to this level, recharging it can be dangerous. Some batteries therefore feature an internal safety circuit which will prevent charging in this state, and the battery will be for all practical purposes dead.[citation needed]

    In circumstances where a second Li-ion battery is available for a given device, it is recommended that the unused battery be discharged to 40% and placed in the refrigerator to prolong its shelf life. While the battery can be used or charged immediately, some Li-ion batteries will provide more energy when brought to room temperature.

    thanks so much for the info. were it not for your reply, i would have likely rendered my battery useless from going with my gut instinct.
    again, thanks for the reply.
    have a good one and be well
