6. STORAGE
Battery Life:
The MESTA UPS should be stored with the batteries fully charged. Storage
temperature should be maintained between -20
°
C and 40
°
C. The life of the batteries may be greatly
reduced if stored at temperatures exceeding 30
°
C for extended periods of time. Optimal storage
temperature for maximum battery life is 20
°
C or lower.
Power Switch:
Make sure the power switch to the UPS is off prior to storing the UPS. Also, batteries
may be permanently damaged if not removed from storage periodically and fully recharged at least
once every 6 months. To recharge batteries inside UPS, simply remove the UPS from storage and
connect the unit to an AC power source and turn it on for a minimum of 4 hours (make sure batteries
are being charged by monitoring the lights on the front panel of the UPS). Then you may turn the unit
off again and return it to storage for up to another 6 months.
