Float Charging:
- Float charging is a maintenance charging technique used to keep batteries fully charged and prevent overcharging.
- It involves applying a constant voltage to the batteries that is slightly higher than their open-circuit voltage.
- The voltage is typically set at 13.8 volts for 12-volt batteries and 27.6 volts for 24-volt batteries.
- Float charging is designed to maintain the batteries at a high state of charge without causing damage or excessive gassing.
- It is usually employed when the batteries are not subjected to heavy loads or frequent deep discharges.
Boost Charging:
- Boost charging is a rapid charging technique used to quickly recharge batteries that have been deeply discharged or are in a low state of charge.
- It involves applying a higher voltage to the batteries than the float charging voltage.
- The voltage is typically set at around 14.4 volts for 12-volt batteries and 28.8 volts for 24-volt batteries.
- Boost charging is designed to bring the batteries back to a full state of charge quickly, but it can cause excessive gassing and shorten battery life if used frequently or for extended periods.
In summary, float charging is a maintenance charging technique that maintains batteries at a high state of charge without overcharging, while boost charging is a rapid charging technique used to quickly recharge deeply discharged batteries but should be used sparingly to avoid damaging the batteries.
