What is battery floating charging voltage?

1. Battery Floating Charging Voltage The voltage at which a battery is maintained once it is fully charged is known as the battery floating charging voltage. This voltage maintains the capacity of the battery by self-discharging it.

What is float charging & how does it work?

Float charging, sometimes referred to as “trickle” charging occurs after Absorption Charging when the battery has about 98% state of charge. Then, the charging current is reduced further so the battery voltage drops down to the Float voltage. The Float charge of a battery keeps the battery at maximum capacity throughout the day.

What is float voltage?

Basically, float voltage is the charge volts needed to keep a battery full... Basically, float voltage is the charge volts needed to keep a battery full... Like in idle state? or similar? Like in idle state? or similar?

What is a normal battery float voltage?

Your 12.7 is the resting voltage, and perfectly normal for a new battery after a few days of self-discharge. Float is essentially the voltage you can set the battery to where the battery will keep itself charged but not over charge. Typically it's 2.25v per cell, so 13.5v for a 12v, but it can vary.
