Abstract A new method for prolonging the life of lead-acid batteries was invented devised by charging the batteries with a high current pulse of a particular pulse width special wavelength.
Charging algorithm: Lead acid battery chargers typically employ a constant voltage or constant current charging algorithm, while lithium-ion battery chargers use a CC/CV charging algorithm.

If the SoC voltage implies the battery OCV is only 12 volts and the charger is putting out 13 volts then clearly there is going to be a charge current. In this scenario the battery has 13 milli ohms and there''s a voltage difference of 1 volt hence, the charge current is going to be around 77 amps.
When charging a lead-calcium battery, it is important to use a charger that is specifically designed for this type of battery. Using a charger that is not designed for lead-calcium batteries can result in undercharging or overcharging, which can damage the battery and reduce its service life.

I would like to use my homemade battery charger, rated 15VDC 7A, to charge a 25Ah lead acid battery. Would there be an easy way to limit the charging current to 2.5A (Ah/10)? As you did your own battery charger, if done with analog electronics, you might have done as a 1, 2 or 3 stage charger, as I will explain further ahead.
Charging a lead-acid battery is a matter of replenishing the amount of energy that the battery has lost during the operation. This recharging operation can be performed with several diferent
In order to avoid excessive gassing or overheating, the charging may also be carried out in two steps, an initial charging of comparatively higher current and a finishing rate of low current.

The ideal charging voltage for a lead-calcium battery is 14.8V, while the typical charging voltage for a lead-acid battery is between 2.15 and 2.35 volts per cell. Using a normal charger to charge a lead-calcium battery may result in undercharging or overcharging, which can damage the battery and reduce its lifespan.
1. Choosing the Right Charger for Lead-Acid Batteries. The most important first step in charging a lead-acid battery is selecting the correct charger. Lead-acid batteries come in different types, including flooded (wet), absorbed glass mat (AGM), and gel batteries. Each type has specific charging requirements regarding voltage and current levels.

To charge a lead acid battery, use a DC voltage of 2.30 volts per cell for float charge and 2.45 volts per cell for fast charge. Check the charge levels and During this time, the current remains high, enabling the battery to absorb energy rapidly. This phase typically lasts until the battery reaches approximately 70-80% of its charge

There is a rumor unspoken rule : the slower charge the better battery, it seems charging current is around C/10 and <= 10A is more favourable to prolong lead acid battery. However, better read the battery specs and datasheet to find out. Example: Your battery capacity is 80Ah, C/10=8A <= 10A, then maximum charging current is 8A.
The maximum charging current for a lead-acid battery is 50% and 30% for an AGM battery. But recharging your battery at this much high amps will decrease the battery life
The recommended charging current for a new lead-acid battery generally follows the “10% rule.” This means the charging current should be approximately 10% of the battery''s capacity (measured in amp-hours or Ah).

When charging, lithium-ion batteries typically use a current rate of 0.5C to 1C, where “C” represents the capacity in amp-hours. Thus, for a 100Ah battery, this translates to a charging current of 50 to 100 amps. However, most manufacturers recommend a lower charging current to prolong battery life, often around 0.2C for optimal performance.
Charging techniques in lead acid batteries take place using varying current magnitudes. Constant current charging techniques are tested to determine charge efficiency. The larger the electric charging currents, the greater the effective energy stored. Larger charging current rates provoke higher temperature increases in older than newer batteries.
