What should be the cut-off voltage for charging lead acid batteries ...
$begingroup$ 11.8V is "OK" - the inverter makers did not want to totally thrash the batteries. Full discharge ~= 10.5V but you REALLY want to avoid discharging that low. Two batteries of original capacity with same load will usefully increase your battery life with a decrease in long term battery cost.

Lead-acid battery State of Charge (SoC) Vs. Voltage (V).
What is Battery Voltage?
The funny thing about battery voltage is that it changes depending on the charge of the battery. At full charge, a battery delivers a higher voltage than when it''s running low or empty. This phenomenon, known as voltage loss, will vary depending on the type of battery. Traditional lead-acid batteries tend to experience much larger voltage ...

How to Equalize Charge a Flooded Battery
What are the recommended steps to equalize a flooded lead-acid battery? To equalize a flooded lead-acid battery, first fully charge the battery, then increase voltage to initiate the equalization charge, which causes controlled overcharging. Monitor specific gravity readings and battery voltage, and stop when there is no further …
Lead Acid Battery Voltage Charts
Charging Voltage Requirements for Lead Acid Batteries. When charging lead acid batteries, proper voltage levels are critical. Here are some key charging voltage requirements to be aware of: Apply a charging voltage of 2.30V to 2.45V per cell, depending on the battery type. Gel and AGM batteries need voltages at the …

At 2.25V per cell (13.5) it would take 85-120 hours to fully charge. As you increase the voltage to get faster charging, the voltage to avoid is the gassing voltage, which limits how high ...
Lead Acid Battery Overcharge: Causes, Prevention, and Proper Charging …
Charging a lead acid battery at high temperatures can cause serious damage to the battery and even lead to explosions. When a battery is overcharged, it may experience: ... During this stage, a constrained steady current is administered onto the battery causing the terminal voltage to increase. The battery charges from 0% to 70% …
Charging Techniques of Lead–Acid Battery: State of the Art
In this paper, the charging techniques have been analyzed in terms of charging time, charging efficiency, circuit complexity, and propose an effective …
6.10.1: Lead/acid batteries
The lead acid battery uses lead as the anode and lead dioxide as the cathode, with an acid electrolyte. The following half-cell reactions take place inside the cell during discharge: At the anode: Pb + HSO 4 – → PbSO 4 + H + + 2e – At the cathode: PbO 2 + 3H + + HSO 4 – + 2e – → PbSO 4 + 2H 2 O. Overall: Pb + PbO 2 +2H 2 SO 4 → ...
