Trickle charging is the process of charging a draining battery to maintain its maximum capacity. When the battery reaches its max level, the process comes to a pause.
This type of charging is beneficial for vehicles at rest or stored away for a long time. It helps maintain the battery life by recharging it gradually.
Overall, in the case of vehicle batteries, this process prevents charge depletion of a battery. So, you don’t need to worry about battery failure on most occasions.
