SLA Battery Replacement
Periodically the SLA battery in the MPS-3111 Series SLA Power Supply will no longer hold a
charge and must be replaced with a new battery.
Keep a record, tracking by department, of SLA battery replacement: high use departments will
need more frequent battery replacement than low use departments.

For safety, only qualified service personnel should perform the following procedure
to replace the MPS-3111 Series Power Supply battery.

New SLA batteries in storage must be maintained by periodically taking them out
and fully charging. Unused SLA batteries in storage will lose charge over time and
if allowed to discharge too completely they will be damaged and unable to hold a
charge. For further information call InterMetro Customer Service.
