Opening the Lantern.
Use this method only as a last resort since it involves disturbing
the factory seal. Any Carmanah self-contained lantern, with or without a charge port, can
always be opened up and charged using the external 120VAC power-pack style battery
charger ($56 option, p/n: 69885)
connected directly to the battery board. If lanterns are
charged using this method, the lantern head must remain electrically
connected
to the
battery board. The battery will fully charge after 24-hours and an intelligent charge
controller built into the lanterns’ circuitry in the lantern head will prevent overcharge if/
when left connected for longer periods of time. Upon charge completion (as indicated by
the decimal point in digital LED display being steady on), let the lantern rest for at least one
(1) hour in the oFF mode (but preferably 24-hours) before confirming settings and
deploying the lantern. However, this method requires the additional step of properly
reassembling the lantern after battery charging is completed. To retain a proper
environmental seal when reassembling the lantern, reconnect the four base plate screws and
tighten each screw down to 50 inch-lbs in a cross pattern using a calibrated torque wrench
as shown below (right).
