When it comes to charging a 12-volt lead-acid battery, it is important to know the maximum charging voltage to ensure the optimal performance and longevity of the battery. According to my research, the maximum charging voltage for a 12-volt lead-acid battery typically falls between 14.4 to 14.7 volts.
This can lead to overcharging and damage to the battery. A float charger, on the other hand, is designed to keep the battery at a constant voltage, which prevents overcharging. Can a trickle charger be used on a sealed lead-acid battery? Yes, a trickle charger can be used on a sealed lead-acid battery, but it is not recommended.
This type of charger will maintain a steady flow of current into the battery, which is necessary to achieve the proper charging voltage. A constant current charger will also help to prevent overcharging, which can damage the battery. 12V VRLA Battery Charging Voltage . If you have a 12v VRLA battery, you need to know the charging voltage. The ...
So as charging continues at a constant voltage, the charging current decreases due to the decreasing potential difference between the charger-output voltage and the battery terminal voltage as the battery charges. Expressed differently, the charging current is highest at the beginning of the charge cycle and lowest at the end of the charge cycle.
The ideal voltage for a fully charged deep cycle battery varies depending on the type of battery. For a 12V lead-acid deep cycle battery, the ideal voltage is between 12.6V and 12.8V. For other types of deep cycle batteries, such as lithium-ion or nickel-cadmium, the ideal voltage may be different.

Then at point #2 the highest safe voltage is reached and the charger goes into constant voltage mode until the current drops to about 10% of the initial value, ...
$begingroup$ Summarizing, the main points are these two: 1) Once a 12V LA battery is down to 10-11V, the voltage will plummet rapidly. No real point in pushing it farther (and risking point 2), given that you only get a few % extra current out of it. 2) If a multi-cell battery is discharged too deeply you risk "polarity reversal" in the weakest cell.
