6 FAQs about [Charging voltage of lead-acid battery in electric vehicle]

How many volts should a lead acid battery charge?

The recommended charging voltage for a lead acid battery is around 2.3 to 2.4 volts per cell, or about 13.8 to 14.4 volts for a 12-volt battery. It’s important to avoid overcharging the battery as it can lead to electrolyte loss and damage to the battery. Can I use a regular car battery charger to charge a lead acid battery?

Can a car battery charger charge a lead acid battery?

Yes, you can use a regular car battery charger to charge a lead acid battery. However, it’s essential to ensure that the charger has a suitable charging voltage and current for the battery. Slow charging is typically recommended to avoid overheating and prolong the battery’s lifespan.

How to adjust the charging voltage of a lead-acid battery?

The charging voltage of a lead-acid battery should be adjusted according to the temperature of the battery. The charging voltage should be increased when the temperature of the battery is low and decreased when the temperature of the battery is high. The voltage of a lead-acid battery also varies with temperature.

What voltage should a lead acid battery be lowered to?

After the current reaches the cutoff point (3-5% of the C rate of the cell) the voltage should be lowered to 13.5V to 13.8V (the "float voltage"). Diagram from the excellent Battery University. Read there article on Lead Acid charging for excellent detailed information .

What happens if you overcharge a lead acid battery?

Overcharging Lead Acid batteries will damage them and can cause Hydrogen and Oxygen gas to form, leading to an explosion risk. You should never, under any circumstances, provide a voltage higher than the rated peak voltage! A charging curve limits the current into the battery until the voltage rises to the peak battery voltage.

What is the peak voltage of a lead acid battery?

Then, the voltage is limited to the peak voltage until the current drops (to 3-5% of the C rate for lead acid batteries). Standard "12V" Lead-acid batteries are six cells; the peak charge voltage is between 13.8 and 14.7V (at 25C, this value is temperature dependent); however prolonged time at this voltage will cause damage.
