Note:
The newer, high-calcium-type 12-volt DC batteries may need pre-charge
activation if their charge has been allowed to drop to a very low level. When deeply
discharged, this type of battery will provide only a very low voltage output and will
draw less than 1 amp during the recharging process, until activated.
Charging if Battery Is Installed in a Vehicle
1. Check polarity of battery terminals - For top-mounted battery connectors, the positive
terminal (marked POS, P, +) usually has a larger diameter than the negative battery
terminal (marked NEG, N, –). For side-mounted battery connections, the positive
terminal is red, the negative terminal is black.
2. Attach charger clamps to battery connections, as follows, ensuring a good connection
(if there is a mistake, the Reverse indicator will light) when the Battery Charger is
plugged in:
For Negative-Grounded Vehicles:
Connect the positive (RED) charger clamp to the
positive (POS, P, +) ungrounded battery terminal. Then, connect the negative (BLACK)
charger clamp to the vehicle chassis, or the engine block (away from the battery).
NOTE: Do not connect the charger clamp to the carburetor, fuel lines or sheet metal body
parts: connect only to a heavy gauge metal part of the frame or engine block.
Negative-grounded type systems are the most common in today’s vehicles.
For Positive-Grounded Vehicles:
Connect the negative (BLACK) charger clamp to the
negative (NEG, N, –) ungrounded battery terminal. Then, connect the positive (RED)
charger clamp to the vehicle chassis or engine part (away from the battery). Do not
connect the charger clamp to the carburetor, fuel lines or sheet metal body parts: connect
only to a heavy gauge, stable metal part of the frame or engine block.
3. Connect the Battery Charger’s power cord to a 110/120-volt AC power outlet.
The digital display will show the battery’s voltage by default;
The Battery Type selector will be at Standard by default;
The Charge Rate selector will be at the minimum rate by default after 10 seconds –
6V/2A or 12V/2A, depending on the battery’s voltage.
Note:
The Battery Charger cannot detect the battery’s nominal voltage actually,
the default charge rate selecting is just based on the battery’s real-time voltage if
it is lower than 8V, the charge rate selector will stay at 6V; if it is higher than 8V
the selector will stay at 12V. To avoid mistake or damage, manually verify and
select a proper charge rate by yourself.
The Charging LED Indicator will be lit after 10 seconds;
4. If the Battery Charger is connected correctly, the Reverse LED indicator will not be lit;
if the cables are connected incorrectly, the Reverse LED will be red. Disconnect the
Battery Charger and check your connections and battery.
5. Select the appropriate charge rate setting and battery type setting for your battery.
6. When the charging is complete, the green Charged LED will be lit.
7. After charging is complete, disconnect the Battery Charger plug from the 110/120-volt
AC power outlet.
8. Disconnect the cables and clamps in the reverse order in which they were connected.
Disconnect your first cable as far away from the battery as possible.
Charging if Battery Is Outside of Vehicle
1. Check polarity of battery terminals - For top-mounted battery connectors, the positive
