According to studies by the Lawrence Berkeley National Laboratory, devices in float mode can lower energy costs by reducing the amount of electricity consumed while still ensuring battery longevity.
How Does Float Mode Protect Lead-Acid Batteries from Damage?
Float mode protects lead-acid batteries from damage by maintaining a safe and efficient voltage level during charging. In float mode, the charger reduces its output voltage after the battery reaches full charge. This process prevents overcharging, which can lead to battery swelling, heat buildup, and reduced lifespan.
When the battery voltage rises to a specific threshold, the float mode stabilizes the voltage at that level, typically around 13.2 to 13.8 volts. This keeps the battery fully charged without excessive strain. The constant low charging current also compensates for self-discharge, which is the natural process where the battery loses charge over time.
By preventing overvoltage conditions and controlling the current, float mode ensures longevity and optimal performance of lead-acid batteries. This approach protects both the battery and equipment reliant on its power, maintaining system reliability over time.
