A lead acid battery charges at a constant current to a set voltage that is typically 2.40V/cell at ambient temperature. This voltage is governed by temperature and is set higher when cold and lower when warm. Figure 2 illustrates the recommended settings for most lead acid batteries.
The research on lead-acid battery activation technology is a key link in the “ reduction and resource utilization “ of lead-acid batteries. Charge and discharge technology is indispensable in the activation of lead-acid batteries, and there are serious consistency problems in decommissioned lead-acid batteries.
Charging and discharging a battery with poor consistency will hardly allow the battery to be effectively activated. According to the characteristics of lead-acid batteries, we carry out research on lead-acid battery activation technology, focusing on the series activation technology of lead-acid batteries with poor consistency.
If the float voltage is set to 2.30V/cell at 25°C (77°F), the voltage should read 2.27V/cell at 35°C (95°F). Going colder, the voltage should be 2.33V/cell at 15°C (59°F). These 10°C adjustments represent 30mV change. Table 3 indicates the optimal peak voltage at various temperatures when charging lead acid batteries.
Heat is the worst enemy of batteries, including lead acid. Adding temperature compensation on a lead acid charger to adjust for temperature variations is said to prolong battery life by up to 15 percent. The recommended compensation is a 3mV drop per cell for every degree Celsius rise in temperature.
Batteries of lead–acid are extensively used in diverse applications like automotive industries, telecommunications systems, hospitals, emergency lighting, power tools, alarm systems, material handling, railway air-conditioning and coach lighting, and so on.

Charging methods for lead acid batteries include constant current
A good rule of thumb is if there is 0.025 points or less between the high and low cell the battery is not defective. Low readings would indicate the battery being discharged. The charging system can have a profound effect on the life of the battery. A high voltage setting can cause excessive gassing and water loss.

As low-cost and safe aqueous battery systems, lead-acid batteries have carved out a dominant position for a long time since 1859 and still occupy more than half of the global battery market [3, 4]. However, traditional lead-acid batteries usually suffer from low energy density, limited lifespan, and toxicity of lead [5, 6].
