According to the Footprint Hero website, a fully charged 6V sealed lead acid battery is around 6.44 volts, while a fully charged 6V flooded lead acid battery is

The ideal charging voltage for a sealed lead-acid battery is between 2.25 and 2.30 volts per cell, or between 13.5 and 13.8 volts for a 12-volt battery. Charging above this voltage can cause the battery to overheat and reduce its lifespan. Avoid overcharging the battery. Overcharging a sealed lead-acid battery can cause it to gas

In conclusion, the best practices for charging and discharging sealed lead-acid batteries include: Avoid deep cycling and never deep-cycle starter batteries.

To charge a sealed lead acid battery, a DC voltage between 2.30 volts per cell (float) and 2.45 volts per cell (fast) is applied to the terminals of the battery. Depending on the state of charge (SoC), the cell may temporarily be lower after discharge than the applied voltage. After some time, however, it should level off.

As a general rule, the higher the voltage, the more charge the battery has. However, the relationship between voltage and state of charge is not always linear. For example, a fully charged 12-volt lead-acid battery will have a voltage of around 12.8 volts, while a partially discharged battery may have a voltage of 12.2 volts or less.

The three tests performed on a lead-acid battery are the open circuit voltage test, the load test, and the internal resistance test. The open circuit voltage test measures the voltage of the battery when it is not being charged or discharged. The load test measures the battery''s ability to deliver current.
