How to Properly Charge a New Lead-Acid Battery for the First Time
Charging a new lead-acid battery for the first time is crucial for its longevity and performance. To properly charge a new lead-acid battery for the first time, use a suitable charger set to a low current, and charge the battery for a prolonged period (ideally 24 hours) at a constant current until the battery reaches full charge, monitoring voltage levels to avoid overcharging;

How does a lead acid battery accept more current when it is
A lead-acid battery like all batteries has memory. (Some more than others) It is due to a double layer capacitance effect and often called something else. When you examine SoC voltages there is a difference of about 1/2V between the OCV and the voltage after some load is applied, so the resting voltage after this load for a Full range SoC is from 12.6 to 11.5.
Optimal charging of valve-regulated lead-acid batteries based
In this paper an algorithm for optimal charging of a valve-regulated lead-acid (VRLA) battery stack based on model predictive control (MPC) is proposed. The main objective of the proposed algorithm is to charge the battery stack as fast as possible without violating the constraints on the charge current, the battery voltage and the battery temperature.

battery charging
A lead-acid cell is nominally 2.0V, but fully charged it''s 2.2V, and "fully discharged" depends on the cell construction and how willing you are to damage it, but is probably around 1.6V to 1.8V. So a "48V" lead-acid battery will have a voltage range of 52.8V down to 43V or even 38V, depending on the original design intent. $endgroup$

$begingroup$ You can use that 15V to charge your SLA Battery but instead of only one diode, put two in series that way you will get a voltage of around 13.6 - 13.8 V which is absolutely fine and will not overcharge your SLA Battery. With 2 diodes in series, charging will stop at 13.8 V which is what you need. You can even leave the SLA Battery connected all the

How to charge lead acid battery?
Following are some tips to be followed while charging Lead Acid Battery: Always keep the battery in a well ventilated space. Do not keep any inflammable liquid like Petrol near the battery. The charger should be plugged in to the AC socket only after it is connected to the battery. Observe the battery while charging.
What is a good charge current for a lead-acid battery?
The charge current for small lead-acid batteries should be set between 10% and 30% of the rated capacity (30% of a 2Ah battery would be 600mA). Larger batteries, such as those used in the automotive industry, are generally charged at lower current ratings.
How much does a lead acid battery weigh?
Lead acid batteries must have a layer cardboard separating each level. This includes a layer of cardboard on the bottom and the top of the load. Typical Pallet Weight (for 3 layers): Between 2800 and 3300 lbs – Pallets are not to exceed 3300 lbs. Only lead-acid batteries may be packaged: No mixing in other batteries or recyclables.
What temperature should a lead-acid battery be charged at?
Temperature Control: Ideally, lead-acid batteries should be charged at temperatures below 80°F (27°C). Charging at high temperatures can lead to thermal runaway, where the battery overheats and becomes damaged. If your battery becomes hot to the touch during charging, stop the process immediately and allow it to cool. 4. Avoiding Overcharging
