Regularly checking the battery’s condition and connections is something I now do to ensure it remains in optimal working condition.

Safety Considerations

Safety is paramount when dealing with batteries, and I made sure to familiarize myself with the safety guidelines. Since SLA batteries are sealed, they are generally safe to use, but I still take precautions.
