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.
