The cut-off voltage for discharging a lead-acid battery typically refers to the voltage at which the battery should no longer be discharged to prevent damage to the cells. For most lead-acid batteries, the general cut-off voltage is around 10.5 to 11.0 volts for a 12V system. This is the voltage where the battery is considered fully discharged.
If you discharge the battery below this voltage, it can lead to:
However, the exact cut-off voltage can vary slightly depending on the specific type of lead-acid battery (e.g., flooded, AGM, gel). Always refer to the manufacturer's guidelines for the most accurate information.
If you discharge the battery below this voltage, it can lead to:
- Sulfation: A condition where lead sulfate crystals form on the battery plates, reducing the battery's capacity over time.
- Reduced lifespan: Continually discharging below this threshold can shorten the overall life of the battery.
