Rechargeable lead-acid batteries are the same type used in automobiles. As with your car battery, how you use this battery has a significant impact on its lifespan. For example, if you forget to turn off your car's lights and drain the battery, a jump start may work a few times. But after a few full discharges, even a jump won't help, and the battery will need to be replaced. With proper use and treatment, a lead-acid battery can last for years. Here are some recommendations for getting the longest life from the internal battery:

- Charge the battery completely after each use.
- Avoid completely draining the battery.
Tips for storing your battery

- For long-term storage, periodically recharge the battery.
- If you do not charge the battery for six months, it may not charge.
