M850/M860 USER MANUAL
CHARGING
Charging the Lantern
If the lantern batteries have a charge of less than
80%, they require charging.
It is recommended that you place the 800 Series
lantern in Off mode for charging. When it is in Off
mode, the lantern can continue to charge using light
on the solar panels, but does not turn on in
darkness.
To place the lantern into Off mode, follow the
command sequence described on page 11, “Turning
the Lantern On or Off”.
Sunlight
If available, sunlight is the easiest way to charge
multiple lanterns. The 800 Series lantern will
typically require five to 10 days to fully charge from
sunlight. Additional charging time may be required in
extremely low light conditions.
External Power Source
The 800 Series lantern may also be equipped with a
quick-access external charge port located in the
base of the lantern. Alternately, the lantern housing
may be removed to access an internal port. Using
either of these options, the light may achieve a full
state-of-charge overnight by connecting the charge
port to an external power source. The wall charger is
intended for indoor use only. Carmanah will supply a
wall charger with adapter on request.
Charge Indicator
When the battery is charging either from sunlight or
from the external charger, a single point on the lower
right of the lantern’s LED display will flash.
If the lantern has been stored
improperly, the batteries may be
sulphated and will not accept a charge.
A new battery may be required.
Charging via an External Power
Source (Quick Access Charge
Port)
Step 1: Tilt the lantern and open the water-tight
charge-port cap.
Step 2: Connect the Carmanah-supplied charger
accessory to the charge port.
Step 3: Align the charger cord with the cord channel
at the base of the lantern.
Step 4: Plug in the charger and let charge overnight.
Wait a minimum of one hour and verify battery state-
of-charge. The most accurate Battery Pack status
reading is obtained when the lantern has been in a
dark location and in “off” mode for at least 24 hours.
