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.
Lead acid charging uses a voltage-based algorithm that is similar to lithium-ion. The charge time of a sealed lead acid battery is 12–16 hours, up to 36–48 hours for large stationary batteries.
Charging of lead–acid cell Discharging of a lead–acid cell The chemical reaction takes place at the electrodes during charging. On charge, the reactions are reversible. When cells reach the necessary charge and the electrodes are reconverted back to PbO 2 and Pb, the electrolyte's specific gravity rises as the sulfur concentration is enhanced.
The batteries should be charged in a well-ventilated place so that gases and acid fumes are blown away. The lead-acid battery should never be left idle for a long time in discharged condition because the lead sulfate coating on both the positive and negative plates will form into hard crystals that will be difficult to break up on recharging.
According to recent research, the failure mode of lead–acid batteries is PAM weakening and shedding, and the battery lifespan is primarily confined to the positive electrode. As a consequence, the lead–acid battery has hit a stumbling block that must be addressed to improve the PAM of the lead–acid battery's efficiency.
Sulphuric acid is consumed and water is formed which reduces the specific gravity of electrolyte from 1.28 to 1.18. The terminal voltage of each battery cell falls to 1.8V. Chemical energy is converted into electrical energy which is delivered to load. The lead-acid battery can be recharged when it is fully discharged.

Get PriceA lithium battery can be charged as fast as 1C, whereas a lead acid battery should be kept below 0.3C. This means a 10AH lithium battery can typically be charged at 10A while a 10AH lead acid battery can be charged at 3A. The charge cut-off current is 5% of the capacity, so the cutoff for both batteries would be 0.5A. Typically, the terminal ...

Get PriceIt is possible to power a load AND charge the battery at the same time, if that is what you are asking. To do this, your solar panel must provide more power than the load requires, so that a bit of excess is available for charging. The simplest arrangement is to place a blocking diode between the solar panel and the battery.
Get PriceThat is still 36V nominal total. Suppose the batteries are in this order (8V,6V,8V,6V,8V). How is it that while charging, you might see 6.9V across each 6V battery but see 9.2V across the 8V batteries? All lead-acid batteries are series strings of 2V cells internally anyway, so it makes no difference how they are grouped.
