Lead–Acid Batteries
The first curve from the left shows what happens if a lead–acid battery is discharged fully each cycle or the depth of discharge is 100%. The maximum cycle life that a battery can reach before the capacity drops to 60% is around 200. The curve for 50% depth of discharge shows a similar trend with the maximum number of cycles between 500 and 600.

BU-403: Charging Lead Acid
The lead acid battery uses the constant current constant voltage (CCCV) charge method. A regulated current raises the terminal voltage until the upper charge voltage limit is reached, at which point the current drops due to saturation. The charge time is 12–16 hours and up to 36–48 hours for large stationary batteries. With higher charge currents and multi-stage

6 FAQs about [Lead-acid batteries get hot when discharged]
What happens during discharge of a battery?
Thus, during discharge, the generated Joule heat heats up the battery, while the electrochemical conversion of lead-based active materials with sulfuric acid to lead sulfate and water is accompanied by an endothermic reaction that cannot be neglected in terms of thermal management of the battery.
How does a lead acid battery work?
When you use your battery, the process happens in reverse, as the opposite chemical reaction generates the batteries’ electricity. In unsealed lead acid batteries, periodically, you’ll have to open up the battery and top it off with distilled water to ensure the electrolyte solution remains at the proper concentration.
Can you lower the temperature of a lead-acid battery during discharging?
Thus, under certain circumstances, it is possible to lower the temperature of the lead-acid battery during its discharging.
Can lead acid damage a battery?
A lack of maintenance or improper maintenance is also one of the biggest causes of damage to lead-acid batteries, generally from the electrolyte solution having too much or too little water. All of the ways lead acid can be damaged are not issues for lithium and why our batteries are far superior for energy storage applications.
How a lead-acid battery can be recharged?
Chemical energy is converted into electrical energy which is delivered to load. The lead-acid battery can be recharged when it is fully discharged. For recharging, positive terminal of DC source is connected to positive terminal of the battery (anode) and negative terminal of DC source is connected to the negative terminal (cathode) of the battery.
How do you know if a lead-acid battery is fully charged?
The following are the indications which show whether the given lead-acid battery is fully charged or not. Voltage : During charging, the terminal voltage of a lead-acid cell When the terminal voltage of lead-acid battery rises to 2.5 V per cell, the battery is considered to be fully charged.
