It consisted of charging the battery at different constant current rates, storing in it, 5 A-hours, in terms of battery capacity, during each of the charging processes, then discharging it while measuring the Capacity Restituted (CR). The charging was performed using a DC supply.
The larger the capacity of the battery, the higher the charge current is usually. Similarly, the higher the charging ratio, the higher the charging current and the shorter the charging time. For internal resistance, the greater the internal resistance, the lower the charging current.
There are four predominantly used methods to charge batteries: Batteries can be charged at constant current but the charging current is supposed to be as small as possible to avoid destroying the battery. This is because uncontrollably high current rates induce gassing in the lead acid battery. Gassing causes the continuous loss of electrolyte.
It was then inferred from this work that the very long time required to charge batteries at lower rates is not only due to the smallness of the magnitude of the current per say but due to the fact that at such low currents, the charging process is ineffective.
Maximum Charging current: It is the upper limit of how high of a current you can provide a battery and charge it while still being in the safe zone.This can change for different types of battery cells with different specification and even different manufacturers.
