    PDF: Self-Discharge and Passivation Phenomena in Lead-Acid Batteriesduring storage
    The passivation of the negative plate brings about the shortening of the discharge time without changing substantially the discharge potential.

    How to calculate battery run-time

    Post  Dr Chaotica on Sat Mar 03, 2018 11:19 am

    A rule of thumb is that for a 1 hour discharge rate (i.e. drawing 10 amps from a 10 amp hour battery, or 1C) you will only get half of the rated capacity (or 5 amp-hours from a 10 amp-hour battery).
    Good article, but I do have one point:
    For lead acid at least, I would always consult the data sheet. Some 12Volt 12 AH sla are rated at 5 hours discharge period, or even 2. A Chilwee 6-DZM-12 fx, is rated 12 Amp-Hours over 2 hours. At the standard 20 Hour rate spec, it gives 16 AH. Even a budget PL12-12 from Ebay is rated at 6.3 AH over 30 minutes.
