How does a battery charger works?

A simple charger works by supplying a constant DC or pulsed DC power source to a battery being charged. A simple charger typically does not alter its output based on charging time or the charge on the battery. This simplicity means that a simple charger is inexpensive, but there are tradeoffs.

Why is my battery charger not working?

So in summary, all issues really are solvable. We went over three major reasons for the battery not charging and their solutions, the first being the poor input source or the charger being in protection mode, the battery temperature being outside of normal charging range, and the safety timer expirations.
