The best voltage to store 12V lithium-ion batteries, specifically lithium iron phosphate (LiFePO4) batteries, is typically between 3.2V and 3.4V per cell. Since a 12V battery usually consists of four cells in series, this translates to a total storage voltage of approximately 12.8V to 13.6V for the entire battery pack. Storing at this voltage range helps maintain battery health and longevity by preventing over-discharge and minimizing capacity loss.
Key Points for Storing 12V Lithium-Ion Batteries
- Optimal Storage Voltage: Aim for 12.8V to 13.6V for a 12V lithium-ion battery.
- State of Charge (SoC): Ideally, store the battery at around 50% SoC or higher to prevent deep discharge.
- Temperature Considerations: Store in a cool, dry place, ideally at temperatures between 15°C (59°F) and 35°C (95°F).
- Periodic Maintenance: If stored long-term, check the voltage regularly and recharge if it drops below the optimal range.
