Important safety Instructions
1- Save these Instructions
DANGER - To reduce the risk of fire or electric shock,
carefully follow these instructions.
2. This charger is intended for use with with 6/12V Lead
Acid Flooded, Gel, Maintenance-Free, AGM Batteries 4Ah-50Ah and
LiFePO4 2Ah – 15Ah lithium rechargeable batteries only. Attempting to
charge other types of batteries may cause personal injury and damage to
the charger. 2

3. Do not expose charger to rain, snow or moisture.
4. Operate charger only in well-ventilated areas. Batteries generate explosive
gases during normal operation.
5. Wear eye protection when operating charger.
6. Never use an extension cord or any attachment not recommended by
manufacturer, otherwise this may result in a risk of fire, electric shock or
personal injury.
7. Do not leave charger unattended while in use.
8. To reduce risk of damage to electric plug and cord, pull by the plug rather
than cord when disconnecting charger.
9. Do not attempt to charge damaged or frozen batteries.
10. Do not operate the charger if the cord or plug has been damaged or if the
charger has been subjected to shock or damage. Take it to a qualified
technician for repair.
11. Do not disassemble the charger. Incorrect reassembly may result in a risk
of electric shock or fire.
12. Unplug the charger from power source before attempting any maintenance
3

or cleaning. Use lint-free cloth to clean the surface, do not immerse into
water.
13. This equipment can be used by children of 8 years and older and by people with
limited physical, sensory or mental capacities or those with no experience and
knowledge if they are supervised or have received instruction in how to use the
equipment safely and understand the dangers which result from such use. Children
are not allowed to play with the equipment. Unless supervised, children are not
allowed to clean the equipment and carry out user-level maintenance work.
14. WARNING: RISK OF EXPLOSIVE GASES WORKING IN VICINITY OF
A LEAD-ACID BATTERY IS DANGEROUS. BATTERIES GENERATE
EXPLOSIVE GASES DURING NORMAL BATTERY OPERATION. FOR THIS
REASON, IT IS OF UTMOST IMPORTANCE THAT YOU FOLLOW THE
INSTRUCTIONS EACH TIME YOU USE THE CHARGER.
To reduce risk of battery explosion, follow these instructions and those published by
the battery manufacturer and the manufacturer of any equipment you intend to use
in the vicinity of the battery. Review cautionary marking on these products and on
engine.
15. The battery charger is not intended for use in electric vehicles

SAFETY & PRECAUTIONS
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 clothing protection. Avoid touching eyes
while working near battery.
4. If battery acid contacts skin or clothing, wash immediately with soap and
water. If acid enters eye, immediately flood eye with running cold water for
at least 10 minutes and get medical attention immediately.
5. NEVER smoke or allow a spark or flame in vicinity of battery or engine.
6. Remove all jewelry and other metallic items from your hands and body when
working with batteries. Metal may spark or create a short circuit resulting in
electrical shock, fire or explosion which may result in injury, death or
property damage.
7. Always use nonconductive or insulated tools when working with any battery.
8. Use charger for charging LEAD-ACID or LITHIUM IRON PHOSPHATE 5

batteries only. Do not attempt to charge any other type of battery. Charging
other battery types may cause injury to persons and damage to property.
9. NEVER USE THE RECOVER MODE FOR A LITHIUM IRON
PHOSPHATE BATTERY.
Location:
Locate the charger as far away from the battery as possible. Do not place the
charger directly above the battery as gases from battery will corrode and
damage charger. Do not allow battery acid to come in contact with charger. Do
not operate the charger in a closed-in area or an area with restricted
ventilation. Do not set battery on top of charger.

WARNING:
Battery terminals, terminals and related accessories contain lead.
Lead compounds are carcinogenic and damage the reproductive system.
PLEASE WASH YOUR HANDS AFTER HANDLING BATTERIES

CHARGING MODES
The HT1500 has three (3) modes. The Lithium charge mode requires the mode
button to be pressed and held for three (3) seconds to enter the enhanced
mode.
This “Enhanced” mode requires your full attention before selecting.
Do not operate the charger until you confirm the appropriate charge mode for
your battery. Here is a brief description.
For charging 12-volt Flooded, Gel, Maintenance-Free batteries.

CONNECTING TO BATTERY
1. Set any charger switches to “off” position and remove AC cord from electric
outlet before connecting or disconnecting DC output clamps or eyelets.
Never allow clamps or eyelets to touch each other.
The battery terminal not connected to the chassis has to be connected first.
The other connection is to be made to the chassis, remote from the battery
and fuel line. The battery charger is then to be connected to the supply
mains; After charging, disconnect the battery charger from the supply mains.
Then remove the chassis connection and then the battery connection.
2. Identify the correct polarity of the battery terminals. The positive battery
terminal is typically marked with (POS, P, +). The negative terminal is
typically marked with (NEG, N, -).
3. Position cords and cables to reduce risk of damage by hood, door or moving
parts (including fan blades, belts, and pulleys) or other parts that could
cause injury to persons.
4. Do not connect to carburetor, fuel lines, or sheet-metal body parts.

charger to the NEGATIVE (NEG, N, -) post of battery.
7. For Positive grounded vehicle, connect NEGATIVE (BLACK) clamp or eyelet
connector from battery charger to NEGATIVE (NEG, N, –) post of battery.
Connect POSITIVE (RED) clamp or eyelet connector from battery charger to
the POSITIVE (POS, P, +) post of battery.
8. When disconnecting charger, turn switches to off, disconnect AC cord,
remove connectors in reverse sequence from connecting procedure.

5. Determine which post of battery is grounded (connected) to the chassis.
If negative post is grounded to the chassis (as in most vehicles) see (6).
If positive post is grounded to the chassis, see (7).
6. For Negative-grounded vehicle, connect POSITIVE (RED) clamp or eyelet
connector from battery charger to POSITIVE (POS, P, +) post of battery.
Connect NEGATIVE (BLACK) clamp or eyelet connector from battery

PREPARING TO CHARGE
1. If necessary to remove battery from vehicle to charge, always remove
grounded terminal from battery first. Make sure all accessories in the vehicle
are off, so as not to cause an arc. 10

2. Be sure area around battery is well ventilated while battery is being charged.
3. Clean battery terminals. Be careful to keep corrosion from coming in contact
with eyes.
4. Study all battery manufacturer’s specific precautions while charging and
recommended rates of charge.
5. Determine voltage of battery by referring to car owner’s manual and make
sure that the output voltage selector switch is set at correct voltage. If charger
has adjustable charge rate, charge battery initially at lowest rate.
