Despite the fact that the batteries you receive from us will be almost fully charged the system will still need to complete and finish off a full charge, with this in mind it will follow that there will be a short period of time that the system is unable to offer its full runtime protection while it is doing this, you will find its better to allow the system to run without load to start while it completes the first charge to reset the new battery energy level

A reasonable life span of batteries is between two to five years, this will unfortunately be very dependent on the general conditions its put under, supplying adequate ventilation is important, the batteries are being continuously used 24/7 the hotter they are allowed to get the shorter the life expectancy, keeping the overall load low will also help prolong the life span, in a ideal world keep it below 40%, many systems are run to the maximum of their capabilities, while they may be able to do this it will have a adverse effect on battery life.
