This varies somewhat depending on the temperature, speed of charge, and battery type. Sealed lead acid batteries are higher in charge efficiency, depending on the bulk charge voltage it can be higher than 95%. Anything above 2.15 volts per cell will charge a lead acid battery, this is the voltage of the basic chemistry.
It is crucial to charge the battery correctly to prevent thermal runaway, battery expiration, and other potential issues. The recommended charging current for a new lead acid battery varies depending on the battery’s size and capacity.
Overcharging a lead acid battery can cause the electrolyte to boil and damage the battery, while undercharging can lead to sulfation, reducing the battery’s capacity and lifespan. To determine the recommended charging current for a lead acid battery, you need to know the battery’s capacity, voltage, and temperature.
Lead acid charging uses a voltage-based algorithm that is similar to lithium-ion. The charge time of a sealed lead acid battery is 12–16 hours, up to 36–48 hours for large stationary batteries.
Drop the charge voltage to about 2.25V/cell if you need a floating charge for emergency response. You may use the power source for equalization of a lead-acid battery by setting the charging voltage 10% higher than recommended. The amount of time spent working overtime is critical and should be kept track of at all times.
The number of amps you should use to charge a 12V lead acid battery depends on its capacity. As a general rule, you should use a charging current of 10% of the battery’s capacity. For example, a 100Ah battery should be charged with a current of 10A.
Lead-Acid Battery Basics
Lead-Acid Battery Cells and Discharging. A lead-acid battery cell consists of a positive electrode made of lead dioxide (PbO 2) and a negative electrode made of porous metallic lead (Pb), both of which are immersed in a sulfuric acid (H 2 SO 4) water solution. This solution forms an electrolyte with free (H+ and SO42-) ions. Chemical reactions ...
Charging Lead-Acid Batteries: Best Practices and Techniques
