Eltorque recommends that independent of the battery health status, the
battery is replaced every five years during vessel classifications to secure
proper functioning when needed.
All deviations to ideal conditions will reduce the battery lifetime.
The following storing conditions are recommended for the product (actuator
and/or battery)
• The storing temperature should be 5 °C to 35 °C.
• The battery must be fully charged before storage.
If the planned storage of the battery is above the limits for storage set by
Eltorque, maintenance charging needs to be done. The below instruction is
the Eltorque recommendation when charging is needed:
• The battery should be charged with CC/CV charging algorithm (900mA
constant current (CC) up to 14.7V. When the charging voltage reaches
14.7V keep the voltage constant (CV) and stop charging when the
charging current reaches 90mA or after 32 hours total CC/CV charging
time.

During planning, please ensure enough space above and around the actuator
for installation, service and manual operation.
There must be a minimum of 150 mm/5.90 in space above and to the sides
of the actuator to accommodate room for installation, operation and service.
