Charging a lead acid battery at high temperatures can cause serious damage to the battery and even lead to explosions. When a battery is overcharged, it may experience: Reduced Battery Life: Exaggerated use increases internal resistance, reducing the number of cycles performed.
Abstract. The traditional methods of charging lead-acid batteries depend on stabilizing the current or voltage through simple electronic circuits, which causes the shorten the life of the batteries due to damage to the electrodes or the hot and dry batteries.
The batteries should be charged in a well-ventilated place so that gases and acid fumes are blown away. The lead-acid battery should never be left idle for a long time in discharged condition because the lead sulfate coating on both the positive and negative plates will form into hard crystals that will be difficult to break up on recharging.
The large charging current at the beginning of the charge is of relatively short duration and will not harm the cells. At the end of the charge the charging current drops to almost zero because the voltage of the battery becomes nearly equal to the voltage of the supply circuit.
Lead–acid batteries may be flooded or sealed valve-regulated (VRLA) types and the grids may be in the form of flat pasted plates or tubular plates. The various constructions have different technical performance and can be adapted to particular duty cycles. Batteries with tubular plates offer long deep cycle lives.
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.

On lead-acid batteries, there is a parameter called "maximum initial current" which is generally written on it. I have added some pictures of it at the end of the question. My confusion is how to interpret it? Is it: The battery can demand more but I should maintain constant current below that limit. OR. The battery will never draw more than ...

charging current of lead acid battery
As a reminder, these are the 3 stages or modes applicable for normal charging of lead acid batteries: Bulk mode: Charging current is limited up to a "safe" value, while the battery voltage increases. It is a constant current (CC) mode. When current starts to reduce, the battery is charged at aprox. 80% of rated capacity.
