First of all, Float Current or Float Charging Current is the current required to keep the batteries at a full state of charge. The float current compensates for the self discharge process when a constant float voltage is applied on the battery.
These include: The float voltage refers to the constant voltage applied to the battery during float charging. It should be set based on the battery manufacturer’s recommendations to avoid overcharging or undercharging. The float current refers to the amount of current supplied to the battery during float charging.
Elevated ambient temperature and float voltage will greatly impact the battery life cycle and can lead to thermal runaway events. It is recognised that for every 10 o C increase in temperature, the float current doubles at a constant float voltage. Likewise for float voltage, every 0.05 Volts per cell increase, the float current typically doubles.
An increase in float current can be a reliable indicator of battery faults and should be taken in consideration along with “internal ohmic measurements” which is the most accurate parameter to calculate the battery SoH (State Of Health) Float current is the current flowing into a fully charged battery.
The float current compensates for the self discharge process when a constant float voltage is applied on the battery. Battery chemistry, battery design, quality of material, manufacturing process and battery capacity (AH) will ultimately influence the rate of self discharge of any lead acid batteries.
Stage 3: Float mode At the point where the current is reduced to C/50 to C/100, the battery charger enters float mode. Float mode is where the voltage on the battery is maintained at approximately 2.25 volts per cell, or 13.5 volts for a 12V battery.

What is Battery Float Charge?
The float charger output is the amount of current that the float charger gives out to charge the battery. This power output is measured in amps and more often you will see your float charger having some amps figures. Float chargers have lower amps usually in the range of 1-3amps. This low charge current means that very little is getting into ...

Float Charging
Since most equipment requires alternating current, a rectifier circuit is usually added between the battery and the load. Float chargers are typically constant-voltage chargers that operate at a low voltage. Operating the charger at a low voltage, usually less than about 2.4 V per cell, keeps the charging current low and thus minimizes the damaging effects of high-current overcharging.
