    Re: trickle charger

    Precharge : A charging method who charges a long unused or brand new battery. It normally uses a small current to charge the battery until predefined voltage level is met. It happens in the beginning of the charging process

    Trickle charging : A charging method which uses to charge the battery at a low rate (C/100), balancing losses through a local action and/or periodic discharge, to maintain the battery in a fully charge condition. Thus, It happens at the end of the charging process.

    For reference, you can refer to the attached.
