4.4. Battery Replacement
!!! Warning !!!
The batteries are a source of energy and can be hazardous if shorted.
Exercise caution.
The batteries are rated for a 5-yr life at 25˚C and 27.5VDC float voltage.
Extended periods of operation above 25˚C will reduce battery life (rule of
thumb: 50% life reduction per every 10˚C increase. After this time it is
appropriate to have a change-out program. In the event of frequent deep
discharges it is possible that the batteries may require earlier replacement.
Prior to disconnecting batteries, disconnect the battery cable from the right
hand side of the rectifier cabinet. Remove jumpers from the battery terminals
and remove old batteries. Install new batteries and reconnect jumpers.
Before reconnecting battery cable to right hand side of rectifier cabinet,
measure open circuit voltage between pins 1 & 2. The voltage should be
above 22VDC. If the voltage is below 22VDC, do not proceed with
connection—batteries must first be charged before installation.
4.5. Battery Recharging
!!! Warning !!!
The batteries are a source of energy and can be hazardous if shorted.
Exercise caution.
The shelf life of the batteries is 6 months from the date of charge. If the
battery has been stored for more than 6 months, it should be recharged prior
to installation.
