Extending your battery's lifespan involves a few key practices:
- Disconnect cables: Always disconnect the negative terminal first to prevent short circuits, then disconnect the positive terminal.
- Check battery's state: For non-maintenance-free lead-acid batteries, visit a professional. For maintenance-free batteries, clean vent pipes and avoid checking electrolyte levels.
- Start charging: Keep the battery upright if removing from the car. Turn off electrical consumers before connecting the charger. Connect the red cable to positive terminal first, then the black cable to negative terminal.
- Stop charging: Switch off charger when fully charged. Disconnect cables starting with the red cable from positive terminal, then the black cable from negative terminal.
