electric spark or open flame in the vicinity of the battery or engine. (For
example: Don't charge the battery next to a gas water heater.)
VENTILATION: Do not operate the charger where ventilation is restricted.
The intent here is to allow sufficient airflow to minimize and dissipate the heat
generated by the charger and to diffuse the gasses that may be emitted by the
battery.
CHARGER MAINTENANCE: NEVER disassemble the charger or attempt to
do internal repairs. Take it to a qualified service technician. Assembling the
charger incorrectly may result in the risk of electric shock or create a fire
hazard.
WARNING
EXTENSION CORDS: An extension cord should not be used unless
absolutely necessary. Using improper extension cord could result in a risk of
fire and electric shock. If extension cord must be used, make sure that:
¾ The pins on the extension cord plug have the same number, size, and
shape as those of the AC power cord plug on the charger;
¾ The extension cord is properly wired and is in good electrical condition; &
¾ The
wire size is as specified in Table 1 below.

PERSONAL PRECAUTIONS
WARNING
WHEN YOU WORK NEAR LEAD-ACID BATTERIES:
1. Someone should be within range of your voice or close enough to come to
your aid if you have an accident;
2. Have plenty of fresh water and soap nearby in case battery acid contacts
skin, clothing, or eyes;
3. Wear complete eye protection and protective clothing. Avoid touching your
eyes while working near a battery. If battery acid contacts your skin or
clothing, wash immediately with soap and water. If acid enters an eye,
immediately flood the eye with running cold water for at least 10 minutes
and get medical attention as soon as possible;
4. Be extra cautious when handling metal tools around a battery. If you drop
a metal tool near a battery it might spark or create a short circuit between
the battery terminals and some other metal part. Either event may cause
a dangerous electrical shock hazard, a fire, or even an explosion;

5. Remove all personal metal items such as rings, bracelets, necklaces, and
watches when working with a lead-acid battery. A lead-acid battery can
produce a short-circuited current high enough to weld a metal ring or other
piece of jewelry, causing a severe burn;
6. Use Battery Tender Battery Charger® High Frequency SMT
Golf Car Chargers for charging lead-acid batteries only. They are not
intended to supply power to an extra low-voltage electrical system or to
charge dry-cell batteries. Charging dry-cell batteries may cause them to
burst and cause injury to persons and damage to property;
INFORMATION NOTE ABOUT DRY-CELL BATTERIES:
There are some wet, non-spillable, lead acid batteries on the market whose
manufacturers' make the claim that they are dry-cell batteries. These batteries
are sealed, gas-recombinant, starved electrolyte, possibly with AGM
(Absorbed Glass Mat) type construction. It is perfectly safe to use
Battery
Tender Battery Charger® High Frequency SMT Golf Car Chargers
to
charge these types of batteries. The dry-cell battery warning is intended for
non-rechargeable, alkaline and other similar types of batteries. If you have any
doubt about the type of battery that you have, please contact the battery
manufacturer before attempting to charge the battery.
7. NEVER charge a visibly damaged or
frozen battery.
PREPARING TO CHARGE: First, follow all General &
Personal Precautions as previously explained, and then
continue.
WARNING
IF THE BATTERY MUST BE REMOVED FROM THE VEHICLE:
1. To avoid an electric arc (or spark), turn off or disconnect all of the
accessories in the vehicle. Then always remove the cable that is
connected to grounded terminal from battery first;
2. If necessary, clean the battery terminals. Be careful to keep the corrosion
and other debris from coming in contact with your eyes;
3. If the battery is not a sealed battery, then if necessary, add distilled water
to each cell until the battery acid solution reaches the level specified by
battery manufacturer. Do not overfill;
4. Check the polarity of the battery posts.
5. Connect the AC power plug to the 120 VAC electrical service outlet. Then
follow the normal start up procedures for the Battery Tender Battery
Charger® High Frequency SMT Golf Car Charger.
WARNING
IF THE BATTERY REMAINS INSTALLED IN THE VEHICLE:
1. Place both the AC and DC power cords in the best position to avoid
accidental damage by movable vehicle parts, i.e. hoods, doors, or moving
engine parts (fan blades, belts, or pulleys).
2. Check the polarity of the battery posts. If the positive (pos, p, +) post is
connected to the vehicle chassis, then the vehicle has a positive ground
system. If the negative (neg, n, -) post is connected to the vehicle chassis,
then the vehicle has a negative ground system. Negative ground systems
are the most common.
