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.

For instance, as a lead acid battery discharges, the voltage can drop below the nominal 2 volts per cell mark, especially if the battery is nearing the end of its life. Additionally, extreme temperatures can impact performance, causing variations in voltage. In summary, a single lead acid battery cell has a nominal voltage of 2 volts.
So it follows that the usable capacity of a lead acid battery is only 50% of the rated capacity. So if you have a 100Ah battery, you can only use 50Ah.
