When the lead acid battery is discharging, the active materials of both the positive and negative plates are reacted with sulfuric acid to form lead sulfate. After discharge, the concentration of sulfuric acid in the electrolyte is decreased, and results in the increase of the internal resistance of the battery.
Operating temperature of the battery has a profound effect on operating characteristics and the life of a lead-acid battery. Discharge capacity is increased at higher temperatures and decreased at lower temperatures. At higher temperatures, the fraction of theoretical capacity delivered during discharge increases.
The nominal capacity of sealed lead acid battery is calculated according to JIS C8702-1 Standard with using 20-hour discharge rate. For example, the capacity of WP5-12 battery is 5Ah, which means that when the battery is discharged with C20 rate, i.e., 0.25 amperes, the discharge time will be 20 hours.
From the above equation, the variation of discharge time is dependent on the discharge current. The battery capacity also greatly depends on the discharge current. This means that the capacity for the one hour rate is 60% less of the 20 hour rate. Evidently, increasing discharge current causes a decrease in the apparent Ah capacity.
3.3 Battery Self-discharge The lead acid battery will have self-discharge reaction under open circuit condition, in which the lead is reacted with sulfuric acid to form lead sulfate and evolve hydrogen. The reaction is accelerated at higher temperature. The result of self-discharge is the lowering of voltage and capacity loss.
For lead-antimony cells the end-of-charge voltage decays progressively during their cycle life to values as low as 2.4 volts after 2000 deep cycles. This characteristic explains a common practice of designing the lead-antimony battery subsystem around the average end-of-charge voltage of 2.40 to 2.45 volts for normal charging rates.

However, if the battery setup is only meant for emergency power and thus only expected to operate a few times a year, discharging a lead acid battery to 80% of capacity is not a big deal. There is no need to add extra battery capacity because the number of charge/discharge cycles is so low that there isn''t that much wear on the battery.
This table provides a clear reference for the relationship between a battery''s C-rating and the estimated discharge time. The C-rating indicates the maximum safe continuous discharge current that can be drawn from the battery, with higher C-ratings allowing for faster discharge but reduced overall capacity.
