batteries each time you service the battery.
3. Keep grass, dirt and debris from collecting near battery
terminals.
4. Batteries are not to remain in a discharged state or
damage to the batteries will occur. Lead sulfate deposits
will form inside the batteries affecting charging and operation.
5. A discharged battery can freeze if left in conditions under
32 degree F (0 degrees C).
6. Charge batteries indoors in a well ventilated and dry
location away from sparks or flames. Never expose
charger to rain, vapor or liquid (dry location use only).
7. Charge only sealed lead acid type rechargeable batteries
Or Lithium Modules (LEMs) provided with the Mean Green Mower.
8. Do not touch un-insulated portion of charger (terminal
pins) of output connector.
9. Do not use with defective cords and wires. Replace
defective cords and wires immediately.
IMPORTANT: Batteries must be attached to a plugged in
battery charger with the charger power switch ON when the unit
is not being used. Failure to keep batteries fully charged will
reduce battery life and void battery warranty.
Battery Charging
NOTE: Lithium Modules can be charged either in or out of mower unit.
LEM10 lithium modules – approx. weight 12 lbs.
LEM20 lithium modules – approx. weight 20 lbs.
WARNING: Use Extreme Caution When Lifting Batteries Out Of Mower Unit.
Serious Injury Could Occur If Battery Is Mishandled or Dropped!!
1. Plug RED charger plug into RED mower charge plug found on end of battery.
(NOTE: Plug will only fit one way into the port. Make sure it is properly aligned before inserting.)
2. IMPORTANT: Turn Ignition Key Switch to FULL CLOCKWISE “ON” position for battery to accept
charge.
3. Turn charger switch to the ON position (on certain models) OR unit will automatically turn on when unit is
plugged into outlet. The cooling fan (on certain models) may or may not engage depending on battery charge level
and charger temperature.
4. Allow 1-12 hours for a full battery charge (depending on battery charger option).
3 green LED lights indicate batteries are Fully Charged OR the red LED indicator will read 0.00
Amps. Leaving batteries on charger longer than 12 hours does not harm the batteries. The charger will
not overcharge batteries.
5. When ready to use mower again after charging, always turn charger OFF before
disconnecting charger from mower. Disconnect charger cord from wall outlet then from the mower.
6. Note: Be sure charger is positioned where air can flow unrestricted into and out of charger.
Charging Recommendations:
WARNING: Do not smoke while servicing the batteries.
WARNING: Always wear safety glasses and protective
clothing near battery. Use insulated tools.
1. Lead acid batteries and Lithium Modules do not develop a memory and need not be fully discharged before
recharging. 2. Over the winter season, when mower is not used regularly, the charger can
be kept plugged into the mower to maintain a full charge on the batteries. Batteries left
uncharged will slowly discharge. Before initial use each spring season, be sure batteries have
a full charge before mowing. 3. If charger is not left plugged in, the batteries should be
