The charging and discharging process of a power battery is a mutual conversion process between electrical energy and chemical energy, so no matter how the positive and negative materials of the battery change, the electrochemical principles are basically similar. The differences between different types of power batteries are mainly reflected in electrochemical

The state of the battery is mainly defined by two parameters: state of charge (SOC) and, state of health (SOH). Both parameters influence performance in the battery and are dependant on each other (Jossen et al., 1999).

Keep in mind that the voltage limit is at 68°F/20°C. Charging at higher or lower temperatures will change this limit. A temperature-sensing charger should always be used, as manual adjustments are never accurate and will damage any VRLA battery.
Valve-regulated lead-acid (VRLA) technology encompasses both gelled electrolyte and absorbed glass mat (AGM) batteries. Both types are valve-regulated and have significant advantages over flooded lead-acid products.
Almost all applications require temperature sensing and voltage compensation. Beware, many chargers measure the ambient temperature which could be significantly different from the battery's internal temperature. Low frequency current ripple (to about 333 Hz) can be detrimental to sealed batteries depending on the application.
The pulse tests were done from 90-10% SOC with 40 pulses of 30A with the length of 20 seconds at each SOC point, an example of a pulse can be seen in figure 14 with a length of 120 seconds. For this measurement, the battery cell was charged to 100% SOC and then discharged 10-20% depending on SOC level for each measurement.
During the pulse tests in figure 13 the voltage amplitude increases instead over time, due to the fact the test is started at 100% SOC and the cell is discharging instead of charging. Therefor it has the reversed effect. There is also an offset in the Gamry current, which slowly discharges the cell which can be seen in figure 16.
For longer pulses it is believed that they will reach the same value as the charge and discharge measurements, which can be seen at the slope for 30A pulse, as it is heading towards the resistance value of charge and discharge measurement.
