The different methods of charging include constant current, constant
voltage and trickle charge.
With constant current charging the series resistance is reduced in order to increase the charging voltage. This may be achieved manually or automatically. The constant voltage system results in a high value of current which gradually falls as the battery charges. The circuit resistance prevents the initial current from being too high.
Trickle charging is used to keep a battery in peak condition—a very low current is continuously passed through the battery and keeps it fully charged.
