What Is Battery Floating Charge?

After the battery is fully charged, use a small current to continue charging the battery. At this time, it is called floating charge, also known as trickle charge. Generally, the small current is not set artificially, but after the voltage is set to the floating charge voltage (for example, the floating charge voltage is within the range of 13.2v ~ 13.8V for 12V battery), the battery has been fully charged, and the current it can accept is very small, so the floating charge current is automatically formed.
