The cutoff voltage for a 12V lead-acid battery typically refers to the voltage below which the battery should not be discharged, to avoid damage and excessive wear. For a 12V lead-acid battery, the cutoff voltage is generally around 10.5V to 11.0V.
Here’s a breakdown:
Some systems, especially those using charge controllers or battery management systems (BMS), might have a higher cutoff (like 11.0V) to protect the battery more conservatively. Always refer to the manufacturer's guidelines for specific cutoff values for your battery.
Here’s a breakdown:
- Fully charged state: 12.6V to 12.8V (when the battery is not under load).
- Discharge cutoff voltage: Around 10.5V (a typical safe lower limit for discharge).
- Deep discharge limit: If the voltage drops below 10.5V, the battery is considered discharged, and it should be recharged to prevent damage. Below this, the battery can suffer from irreversible damage, shortening its lifespan.
