OPERATING INSTRUCTIONS
Charging Using the Supplied Battery Clips
WARNING: A spark near the battery may cause an explosion. To reduce the risk of a
spark near the battery, position AC and DC cords away from hood, door, or moving
engine parts.
1. Insert the double barrel tip of the battery clamp cable into the double barrel tip of the battery maintainer
cable (male-to-female and female-to-male). Then plug the battery maintainer’s power cord into an AC
outlet. The power LED will light blue to indicate that the maintainer is plugged in and ready.
2. Check polarity of battery posts. Positive (POS, P, +) battery post usually has larger diameter than
negative (NEG, N, –) post.
3. Determine which post of battery is grounded (connected) to the chassis. If negative post is grounded to
chassis (as in most vehicles), see 4. If positive post is grounded to the chassis, see 5.
4. For negative-grounded vehicle, connect positive (red) clamp from battery maintainer to positive
(POS, P, +) ungrounded post of battery. Connect negative (black) clamp to vehicle chassis or
engine block away from battery. Do not connect clip to carburetor, fuel lines, or sheet-metal body
parts. Connect to heavy gauge metal part of the frame or engine block.
5. For positive-grounded vehicle, connect negative (black) clamp from battery maintainer to
negative (NEG, N, –) ungrounded post of battery. Connect positive (red) clamp to vehicle chassis
or engine block away from battery. Do-not connect clip to carburetor, fuel lines or sheet-metal
body parts. Connect to a heavy gauge metal part of the frame or engine block.
Note:
If the clamps are incorrectly connected with regard to polarity, the reverse polarity/fault LED ( ) will light. Unplug the
maintainer; then remove the clamps. Reconnect the clamps properly.
6. When the unit is properly connected and charging, the battery charging LED ( ) will light yellow
to indicate the battery is charging.
7. When the charging complete LED ( ) lights green, the battery is fully charged.
When disconnecting maintainer, disconnect AC cord, remove clamp from vehicle chassis, and then
remove clamp from battery terminal.
Charging Using the 12 Volt DC Accessory Plug
The 12 Volt DC Accessory Plug may be used with the battery installed.
1. Insert the double barrel tip of the 12 volt DC accessory plug cable into the double barrel tip of
the battery maintainer cable (male-to-female and female-to-male). Then plug the battery maintainer’s
power cord into an AC outlet. The power LED will light blue to indicate that the maintainer is
plugged in and ready.
2. Insert the 12 volt DC accessory plug into the vehicle’s 12 volt DC accessory outlet. Rotate the
adapter slightly to make sure there is good contact.
3. When the unit is properly connected and charging, the battery charging LED ( ) will light to
indicate the battery is charging.
4. When the charging complete LED ( ) lights, the battery is fully charged.
When disconnecting maintainer, disconnect AC cord, and then remove the 12 volt DC accessory plug
from the vehicle accessory outlet.
SETTING UP THE UNIT
Ensure that all installation and operating instructions and safety precautions are understood and
carefully followed by anyone installing or using the battery maintainer. Follow the steps outlined in
the “Important Safety Instructions” section of this manual.
To Mount the Unit Using the Magnetic Discs:
The magnetic discs in the bottom of the unit allow you to position the battery maintainer on any flat,
secure metallic surface.
To Mount the Unit Using the Hanging Hook:
The hanging hook allows you to position the battery maintainer for convenient, hands-free operation.
CAUTION – TO REDUCE THE RISK OF PRODUCT DAMAGE:
• When the maintainer is hung by the hanging hook or attached using the magnetic discs,
do not shake the maintainer or object that it is hanging from or attached to. Do not hang
the maintainer from or attach the maintainer to any electrical wires or anything that it is
not secure.
• Only use the hanging hook or magnet discs for hanging or positioning the maintainer. The
hanging hook and magnetic discs are not intended to support additional weight. Do not attach
or hang anything additional to the maintainer or risk of breakage may occur.
Preparing to Charge
1. Remove battery completely from boat/airplane or any confined area before charging when using
the battery clips or the ring terminals..
2. If it is necessary to remove battery from vehicle to charge, or to clean terminals, always remove
grounded terminal from battery first. Make sure all accessories in the vehicle are off, so as not
to cause an arc.
3. Clean battery terminals, taking care to avoid getting corrosive material in eyes.
4. Add distilled water in each cell until battery acid reaches level specified by battery manufacturer.
This helps purge excessive gas from cells. Do not overfill. For a battery without cell caps
(maintenance free), carefully follow manufacturer’s charging instructions.
5. Study all battery manufacturer’s specific precautions, such as removing or not removing cell
caps while charging, and recommended rates of charge.
Maintainer Location
• Locate maintainer as far away from battery as cables permit.
• Never place maintainer directly above battery being charged; gases from battery will
corrode and damage maintainer.
• Never allow battery acid to drip on maintainer.
• Never operate maintainer in a closed-in area or restrict ventilation in any way.
• Marine batteries must be removed and charged on shore.
• Do not set a battery on top of maintainer.
