BU-403: Charging Lead Acid
The charge time is 12–16 hours and up to 36–48 hours for large stationary batteries. With higher charge currents and multi-stage charge methods, the charge time can be reduced to 8–10 hours; however, without full topping charge. Lead acid is sluggish and cannot be charged as quickly as other battery systems. (See BU-202: New Lead Acid

All You Need To Know About Lead-acid Batteries
Never boost-charge any battery that is below 11.00 Volts as it will be too sulphated to accept a charge; scrap the battery or charge normally. Only use a boost-charger that limits the charging voltage to a maximum of 14.2 Volts and that has a temperature monitor.

Can I recharge a completely dead sealed lead acid battery?
In ideal circumstances an SLA battery should never be discharged by more than 50%, for a maximum life span no more than 30% (to a 70% state of charge). If it''s completely dead, it''s gone and you need to find a replacement.

How to revive a dead car battery | Batteries Plus
Sulfation can be reversed in a flooded lead acid battery if it is detected early enough. You can do this by applying an overcharge to a fully charged battery using a regulated current of around 200mA (milliAmps) for a period of roughly 24 hours. This allows the battery''s terminal voltage to rise between 2.50 and 2.66 volts per cell, which helps to dissolve sulfate

However, conventional lead acid battery cannot be recharged after over discharge and the performance is greatly declined. It has been revealed that the cause of not being able to be recharged is the formation of α-PbO 2 on the surface of β-PbO 2 cathode active material due to local cell reaction between lead current collector and β-PbO 2.

How often should a lead acid battery be charged?
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.
Can a lead acid battery be charged at a full charge?
Test show that a heathy lead acid battery can be charged at up to 1.5C as long as the current is moderated towards a full charge when the battery reaches about 2.3V/cell (14.0V with 6 cells). Charge acceptance is highest when SoC is low and diminishes as the battery fills.
What happens if a lead acid battery doesn't start a car?
Just because a lead acid battery can no longer power a specific device, does not mean that there is no energy left in the battery. A car battery that won’t start the engine, still has the potential to provide plenty of fireworks should you short the terminals.
Can lead acid battery be recharged after over discharge?
However, conventional lead acid battery cannot be recharged after over discharge and the performance is greatly declined. It has been revealed that the cause of not being able to be recharged is the formation of α-PbO 2 on the surface of β-PbO 2 cathode active material due to local cell reaction between lead current collector and β-PbO 2.
Should you charge a lead-acid battery with a saturated charge?
We’ve put together a list of all the dos and don’ts to bear in mind when charging and using lead-acid batteries. Apply a saturated charge to prevent sulfation taking place. With this type of battery, you can keep the battery on charge as long as you have the correct float voltage.
What happens if a lead acid battery is flooded?
If lead acid batteries are cycled too deeply their plates can deform. Starter batteries are not meant to fall below 70% state of charge and deep cycle units can be at risk if they are regularly discharged to below 50%. In flooded lead acid batteries this can cause plates to touch each other and lead to an electrical short.
