A long-life low-maintenance battery pack designed for low or infrequent use environments. The lithium battery pack requires less maintenance than the SLA battery pack since it never requires recharging. A new lithium battery pack may last up to 5 years when installed in the LIFEPAK 500 AED under optimal conditions. No rechargable.
