Figure 4 : Chemical Action During Discharge When a lead-acid battery is discharged, the electrolyte divides into H 2 and SO 4 combine with some of the oxygen that is formed on the positive plate to produce water (H 2 O), and thereby reduces the amount of acid in the electrolyte.
No,\ the battery is not charging and discharging at the same time. When the charging system (solar panel or alternator) is below the voltage of the battery, the battery supplies the needed current instead. It can supplement the charge coming from the charging system, but it is not being charged.
As a lead-acid battery is charged in the reverse direction, the action described in the discharge is reversed. The lead sulphate (PbSO 4) is driven out and back into the electrolyte (H 2 SO 4). The return of acid to the electrolyte will reduce the sulphate in the plates and increase the specific gravity.
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.
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.
The following are the indications which show whether the given lead-acid battery is fully charged or not. Voltage : During charging, the terminal voltage of a lead-acid cell When the terminal voltage of lead-acid battery rises to 2.5 V per cell, the battery is considered to be fully charged.

It 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.

I feel it has something to do with the AC ripple caused by simultaneously charging the battery, while also discharging through the lamp, but I found no explanation for this either. Has anyone experienced something similar, or can explain why it occurs?
So we did an experiment to test this, consisting of a lead-acid, 70 Ah battery, a 25A RMS charger (old style, just a transformer and full-wave rectifier) and a 55 W automotive lamp. The lamp, battery and charger were all connected in parallel. Similarly, over time, disconnecting the setup and checking the battery voltage, it was decreasing. I should note that to exclude the battery …
I like the MPP and Growatt All-in-one for the ability to "pass through". I was wondering if it wouldn''t be a better match to use lead acid batteries, as they would be healthier fully charged the vast majority of the time. Or, would it be better to use lifepo4, and set it to charge to something like 60%, and discharge only to 30%? Is there a way ...
