Power-Sonic PSC 12800A - Manual (Page 5)

Check the open circuit voltage of the battery to see if it has any shorted cells - there should be about
2.15 V/cell for a properly charged battery (divide the battery voltage by two to get the number of
cells). If the battery voltage looks correct then you may be trying to charge a battery which has too
large a capacity for the charger (see charging notes and tips).
RATTLE - If you think you hear a rattle inside the charger it is probably only a loose terminal strip
screw. Once the output cable is attached the rattle should go away.
MAINTENANCE INSTRUCTIONS
CLEANING - Unplug the charger before attempting any cleaning. If it becomes necessary to clean the
enclosure, wipe the exterior of the enclosure with a damp cloth and a mild detergent. Do not use an
abrasive cleanser. Do not spray cleaners directly onto the charger or immerse unit in water.
