The solid-state components of the charging circuit can sometimes allow a very low current through. This may cause minimal damage, but charging circuits are continually improving.

A trickle charger provides a low current to the battery for slow charging. If it does not have a built-in automatic cutoff, it will continue to provide the current even when the battery is fully charged. The simplest method is to work out charging time from the charger amps and the battery amp-hour rating. However, the initial starting voltage of the battery also affects.
