@All.

How do you think the polarity will vary the charging and discharging principle. Is it the same polarity for both?

To charge 12v battery connect red (positive) charger terminal to positive terminal post on the battery and black (ground terminal) to the negative battery post. And when we want to use the battery power we plug at the same terminal!

To discharge the battery we have to reverse the direction of applied voltage.

In this positive pole is connected to positive pole of the battery and negative to negative pole of the battery for charging and for discharging positive to negative and negative to positive irrespective of voltage.

You are correct @Prasu.

@Prasu.

But in answer applying voltage not the chemical reaction.

Prasu said:   9 years ago
If you want to charge a battery then you must have to reverse the chemical action takes place while discharging. So, in (C) option it must be discharging instead of charging.

What is it mean by applying voltage in the reverse direction to that of charging?
