Assume that the cell is fully charged. When it starts discharging, the current starts flowing from the cell to the external load as shown in Fig. 2. Due to this current, the sulphuric acid H 2 SO 4 is disassociated into positive H 2 and negative SO 4 Ions. The external load current flows from anode to cathode, but the internal current flows from cathode to anode

How to Fix a Reverse Polarity Battery: Introduction and Usage
When the lead elements in the two electrodes of a lead acid battery are reverse-charged, they may polarize in the opposite direction. Attempts to remedy the problem by charging in the other way are futile because the reversal would oxidize a critical organic component in the usual negative electrode. Furthermore, there is a strong probability of a short forming during a

I''ve seen people ask how to discharge a lead-acid battery, which is easy enough. I have a lead-acid battery that I must have connected to my on-board boat charger backwards. It must have been very dead, because it reversed the polarity. I know to reverse it back, I''ll need to discharge the battery pretty completely.

How to charge a lead-acid battery?
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.
What happens if a car battery is connected wrongly?
If a battery in the first car is connected wrongly to the battery placed in another car to charge the second battery through the first one, it may explode and burn or permanently damage the battery (ies).
