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.
Those batteries that are used in deep discharge cycling mode can be charged up to 2.45 volts/cell (14.7V for a 12V battery) to get the highest charge rate, as long as the voltage is dropped to the float voltage when the charge is complete. Voltage table for cyclic use charging.
There are two methods of charging for this use. Two-step constant voltage charge control method uses two constant-voltage devices. At the initial stage, the battery is charged by the first constant-voltage device SW(1) of high setup voltage (set-up for cycle charge voltage).
A lead acid battery is considered fully charged when its voltage level reaches 12.7V for a 12V battery. However, this voltage level may vary depending on the battery’s manufacturer, type, and temperature. What are the voltage indicators for different charge levels in a lead acid battery?
This is why a battery charger can operate at 14.4 to 15 volts during the bulk-charge phase of the charge cycle. Using modern precision chargers allows both a fast charge and safe floating voltages, allowing them to be left on the battery continuously.
Ballast was also a component used in early model automobile engines that lowered the supply voltage to the ignition system after the engine had been started. Starting the engine requires a significant amount of electrical current from the battery, resulting in an equally significant voltage drop.
My standby charge for a 20Ah sealed lead-acid battery starts when battery voltage reaches 12.8V, after which I charge with constant voltage at 13.65V until charge …

This technique uses a combination filament–cathode at each end of the lamp in conjunction with a mechanical or automatic (bi-metallic or electronic) switch that initially connect the filaments in series with the ballast to preheat them. When filaments are disconnected, an inductive pulse from the ballast starts the lamp. This system is described as "Preheat" in North America and "Switch Start" in the UK, and has no specific description in the rest of the world. This system is commo…
