Battery Specifications Explained

In 1897 a German physicist, W. Peukert, determined that the capacity of a lead–acid battery depends on the discharge rate of the battery, saying that high discharge rates decrease the storage capacity by a predictable factor. [{{C}_{P}}={{I}^{k}}t] Where: C is the capacity in Ah @ 1 amp discharge. I is the actual discharge current in amps.

A battery''s capacity is commonly rated at 1C, indicating that a fully charged battery rated at 1Ah should provide 1A of current for one hour. By adjusting the discharge rate, the battery can provide different levels of current over varying durations.

Everything you need to know about reading a battery''s datasheet

For Li-SOCl2 bobbin cells, which are optimized for discharge currents in the range of a few mA, the higher the discharge current, the quicker the discharge and the lower the overall capacity (Ah). In this graph from the LS 14500 datasheet, the battery has a maximal capacity of 2.6 Ah at a discharge current of 1 mA (when at 20°C).
