Charging For Float Standby Applications
Charged at 2.275 volts per cell continuous. The battery will seek its own current level and float fully charged. However, users should be aware that when charging from fully discharged, the battery can draw an initial charge current of approximately 2cA. Care should therefore be taken to ensure that this initial charge current (if ungoverned) is within the output capability of the equipment. Final charge current at 2.275 volts per cell is typically between 0.0005cA to 0.004cA.
Charging For Cyclic Applications See cyclic recharge regime graph.
CAUTION- Do not Short Circuit- Do not charge in a sealed container- Service life and operational characteristics will be affected by temperature- AC Ripple reduces service life.
WARNING! The battery must never be installed permanently suspended by their handles; they are not designed for this purpose.
