PREPARING TO CHARGE
1. Be sure area around battery is well ventilated while battery is being
charged.
2. Remove battery completely from boat/airplane or any confined area
before charging.
3. 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.
4. Clean battery terminals, taking care to avoid getting corrosive material
in eyes.
5. 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.
6. Study all battery manufacturer's specific precautions, such as removing
or not removing cell caps while charging, and recommended rates of
charge.
7. Determine voltage of battery to be charged by referring to the vehicle
manual. The unit is for charging a 12 volt battery only.
CAUTION:
This battery charger/maintainer does not detect, diagnose
or analyze the condition of the battery. Attempting to charge/maintain a
battery with an abnormal condition can further damage the battery. If in
doubt, have the battery checked by a qualified professional prior to using
the charger/maintainer.
CHARGER LOCATION
• Locate the battery charger as far away from battery as cables permit.
• Charge above freezing temperature and below 40°C (104°F).
• NEVER place the battery charger directly above battery being charged;
gases from battery will corrode and damage charger.
• NEVER allow battery acid to drip on the battery charger when reading
gravity or filling battery.
• NEVER operate the battery charger in a closed-in area or restrict
ventilation in any way.
• Marine batteries must be removed and charged on shore. To charge it on
board requires equipment specially designed for marine use. This unit is
NOT designed for such use.
CONNECTION PRECAUTIONS
• Disconnect the AC plug from the electric outlet before connecting or
disconnecting the clamps.
• Never allow the clamps to touch each other.
• Attach clamps to battery and chassis as indicated in the appropriate
section ("Charging a battery installed in a vehicle" or "Charging a battery
that has been removed from a vehicle").
CHARGING A BATTERY INSTALLED IN A
VEHICLE
WARNING –
A spark near the battery may cause an explosion. To
reduce risk of a spark near the battery:
1. Position clamp cords to reduce risk of damage by hood, door, or moving
engine parts.
2. Check polarity of battery posts. The positive (POS, P, +) battery post
usually has a larger diameter than the negative (NEG, N, –) post.
3. Determine which post of the battery is grounded (connected to the
chassis). If the negative post is grounded to the 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 charger to positive (POS, P, +) ungrounded post of battery.
Connect the negative (BLACK) clamp to the vehicle chassis or engine
block away from the battery. Do not connect the clamp 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 charger 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
4
body parts. Connect to a heavy gauge metal part of the frame or engine
block.
When disconnecting the charger, disconnect AC plug, remove the clamp
from the vehicle chassis, and then remove the clamp from the battery
terminal.
CHARGING A BATTERY THAT HAS BEEN
REMOVED FROM A VEHICLE
WARNING –
A spark near the battery may cause an explosion. To
reduce risk of a spark near the battery:
