DIAGRAM OF CHARGER
Make sure the provided charger and adapter is used for the charging. Using a charger not
provided with the product for performing the charging process could result in overheat or possible
burning. Please always charge the Orca H9 in a cool, dry and well ventilated environment.

CHARGING PROCEDURE
WARNINGS FOR CHARGING
CHARGER SPECIFICATIONS
Standard charger is recommended for regular use to prolong the life of the batteries.
1. Move the Orca H9 and charger to sheltered, dry, clean & well-ventilated area.
2. Ensure the Orca H9 unit and charger are both switched off.
3. Remove the protective charger cap and place it to somewhere dry and clean.
4. Ensure there is no moisture, sand, grease or debris in any part of the female or male
connector. Wipe clean with a dry cloth if necessary.
5. Connect the male connector on the lead to the female connector on the the Orca H9 unit.
6. Switch on the charger.
7. When batteries are fully charged (standard charger full charge = approximately 6 hours &
fast charger full charge = 2 hours), switch off the charger.
8. Disconnect charger lead from the Orca H9 unit.
9. Ensure there is no sand, moisture, grease or debris on the charger cap or charge port and
replace cap.
10. Tighten the cap to finger tight. Excessive tightening may damage the thread or O-ring seal.
Insufficient compression will allow water to penetrate the connector and cause a short
circuit.
1. We recommend periodically charging the Orca H9 when in long-term storage to help
prolong the battery life. For ambient storage temperatures under 25 ℃ (77 ° F) - charge
once every 3 months, for ambient storage temperature over 25 ℃ (77 ° F) - charge once
every 2 months.
2. For air-freight shipping, please discharge batteries to 30%.
3. Ensure the charger lead is connected to the Orca H9 charge port before turning the charger
on. Failure to do so may cause a surge or sparks between male and female connector.
4. Regularly check the charge cover cap and seals. O-rings degrade over time and may
require replacing.
5. Do not obstruct the fan on the charger units, as it will cause the charger to overheat and
automatically cut-off.
6. Keep the charger away from flammable substances. Small sparks may be caused when
connecting the lead to the charge port.
7. Batteries are designed to go through approximately 1200 charge/discharge cycles, and the
charge capacity will gradually reduce over time. We recommend replacing the batteries
after 36 months or 1000 charge/recharge cycles.
8. Expired lithium Ion batteries need to be professionally disposed or recycled. Do not
burn / incinerate or throw in regular domestic trash. Please consult your local council /
government on how to properly dispose in your locality.
9. Ensure the charger is always used with an earth connection – without a good ground
connection the charger can build in casing and there is a risk of electric shock, especially
in humid or salt-water environments.
