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.
One common reason why a sealed lead acid battery might not hold a charge is due to a lack of maintenance. If the battery is not charged properly, or is left unused for long periods of time, it can become depleted and unable to hold a charge. Additionally, if the battery is overcharged, it can become damaged and unable to hold a charge as well.
Charging a 6V battery largely depends on its capacity, the state of its charge, and the charger being used. However, there are some general guidelines to consider: Charging Method: The lead acid battery, which is a common type of 6V battery, uses the constant current constant voltage (CCCV) charge method.
When a sealed lead acid battery is charged, electrical energy is converted into chemical energy, which is stored in the battery. The lead plates and lead oxide plates react with the electrolyte to form lead sulfate and water. When the battery is discharged, the lead sulfate and water react to form lead, lead oxide, and sulfuric acid.
It is safe to fast-charge all lead acid batteries with modern fast charge algorithms. Typical Charging curves for PowerStream quick chargers. This charger starts at 8 amps and maintains a near-constant current until nearly full. This is the fundamental algorithm of the PowerStream quick chargers for lead acid batteries.
This mode works well for installations that do not draw a load when on standby. Lead acid batteries must always be stored in a charged state. A topping charge should be applied every 6 months to prevent the voltage from dropping below 2.05V/cell and causing the battery to sulfate. With AGM, these requirements can be relaxed.

Look at the (actually excessive) charge voltage printed on your battery. Now look at your power supply. Like it says, you need to apply a constant voltage of 7.2 to 7.5 volts (or the lower voltage range for "trickle" standby charging). It might be sensible to start with a lowish voltage e.g. 7v if the battery has been discharged for a long time.
