The lead-acid cell can be demonstrated using sheet lead plates for the two electrodes. However, such a construction produces only around one ampere for roughly postcard-sized plates, and for only a few minutes. Gaston Planté found a way to provide a much larger effective surface area. In Planté''s design, the positive and negative plates were formed of two spirals o…
Lead acid battery can be discharged either at a slow rate for long time or at a high current for a short period. For example, a 10Ah lead acid battery can be discharged at 0.1C rate and will give 1 Amps current for 10 hours. If the same battery is discharging at 1C, it gives 10 Amps current for 1 hour only. The discharge rate is linear on low ...

Then, as the acid diffused through the cells, the concentration at the plates'' surface would increase and cause the battery to spring back to life. In similar fashion, the voltage of a battery during charge increases due to the acid concentration that occurs at the plates'' surface. If the charge rate is significant, the voltage will rise rapidly.
Ideally the manufacturer supplies the discharge rates on the battery datasheet. A quick point: You mention you have a 12 V 2.4 A SLA (sealed lead acid) battery, but batteries are rated in amp-hours not amperes. Therefore I suspect you have a 12 V 2.4 Ah battery.

Fig. 2 b and c shows that with increase of H 2 SO 4 concentration the utilization of NAM increases, while the H 2 SO 4 utilization decreases. In the H-region of acid concentrations (C H 2 S O 4 < 1.27 sp. gr.) the utilization of NAM varies between 40 and 63%, while that of H 2 SO 4 is between 68 and 80%. During these capacity tests the discharge current (I disch = C o …
