Question

what is
meant by trickle change?​

Answer 1

Answer:

Trickle charging means charging a fully charged battery at a rate equal to its self-discharge rate, thus enabling the battery to remain at its fully charged level; this state occurs almost exclusively when the battery is not loaded, as trickle charging will not keep a battery charged if current is being drawn by a load.[1][2] A battery under continuous float voltage charging is said to be float-charging.[3
