This manual contains important safety and operating instructions.
WARNING
WARNING
RISK OF ELECTRIC SHOCK OR FIRE.
1.1 Read the entire manual before using this product. Failure to do
so could result in serious injury or death.
1.2 Children should be supervised to ensure that they do not
play with the appliance. This appliance can be used by children
aged from 8 years and above and persons with reduced physical,
sensory or mental capabilities or lack of experience and knowledge if they have been given
supervision or instruction concerning use of the appliance in a safe way and understand
the hazards involved. Children shall not play with the appliance. Cleaning and user
maintenance shall not be made by children without supervision.
1.3 This charger is not intended for use by persons (including children) with reduced physical,
sensory or mental capabilities, or lack of experience and knowledge, unless they have been
given supervision or instruction concerning the use of the charger by a person responsible
for their safety. Children should be supervised to ensure they do not play with the charger.
1.4 Do not expose the charger to rain or snow.
1.5 Use only recommended attachments. Use of an attachment not recommended or sold by
Sealey may result in a risk of re, electric shock or injury to persons or damage to property.
1.6 To reduce the risk of damage to the electric plug or cord, pull by the plug rather than the
cord when disconnecting the charger.
1.7 An extension cord should not be used unless absolutely necessary. Use of an improper
extension cord could result in a risk of re and electric shock. If an extension cord must be
used, make sure:
• That the pins on the plug of the extension cord are the same number, size and shape as
those of the plug on the charger.
• That the extension cord is properly wired and in good electrical condition.
• That the wire size is large enough for the AC ampere rating of the charger as specied in
section 8.
1.8 To reduce the risk of electric shock, unplug the charger from the outlet before attempting
any maintenance or cleaning. Simply turning off the controls will not reduce this risk.
1.9 Do not operate the charger with a damaged cord or plug. If the supply cord is damaged, it
must be replaced by the manufacturer, its service agent or similarly qualied persons in order
to avoid a hazard.
1.10 Do not operate the charger if it has received a sharp blow, been dropped or otherwise
damaged in any way; take it to a qualied service person.
1.11 Do not disassemble the charger; take it to a qualied service person when service or repair
is required. Incorrect reassembly may result in a risk of re or electric shock.
RISK OF EXPLOSIVE GASES.
WARNING
1.12 WORKING IN THE 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.
1.13 To reduce the risk of a 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 the cautionary markings on these products
and on the engine.
1.14 This charger employs parts, such as switches and circuit breakers, that tend to produce
arcs and sparks. If used in a garage, locate this charger 18 inches (46 cm) or more above
oor level.
WARNING
IMPORTANT
Do not use with non-rechargeable batteries.
Use only with lead-acid or lithium ion LiFePO4 rechargeable batteries.
Do not start the vehicle with the charger connected to the AC outlet, or it
may damage the charger and your vehicle.

2. PERSONAL PRECAUTIONS
WARNING
RISK OF EXPLOSIVE GASES.
2.1 NEVER smoke or allow a spark or ame in the vicinity of a battery or engine.
2.2 Remove personal metal items such as rings, bracelets, necklaces and
watches when working with a lead-acid or lithium ion battery. These batteries can
produce a short-circuit current high enough to weld a ring or the like to metal,
causing a severe burn.
2.3 Be extra cautious, to reduce the risk of dropping a metal tool onto the battery. It might
spark or short-circuit the battery or other electrical part that may cause an explosion.
2.4 Use this charger for charging only 12V automotive/power sport batteries, including 6-celled
lead-acid and 4-celled lithium LiFePO4 batteries, with rated capacities of 3-50Ah (12V)*. It is
not intended to supply power to a low voltage electrical system other than in a starter-motor
application. Do not use this battery charger for charging dry-cell batteries that are commonly
used with home appliances or lithium ion batteries used in cell phones, laptops, power tools, etc.
These batteries may burst and cause injury to persons and damage to property.
*The SPI3S has been tested and approved to charge the ChaoBaLi LiFePO4 battery,
model number TDS-1220AH-1. Before charging any other LiFePO4 battery, we
recommend contacting the battery supplier.
2.5 NEVER charge a frozen battery.
2.6 Consider having someone nearby to come to your aid when you work near a lead-acid battery.
2.7 Have plenty of fresh water and soap nearby, in case battery acid contacts your skin,
clothing or eyes.
2.8 Wear complete eye and body protection, including safety goggles and protective clothing.
Avoid touching your eyes while working near the battery.
2.9 If battery acid contacts your skin or clothing, immediately wash the area with soap and
water. If acid enters your eye, immediately ood the eye with cold running water for at least
10 minutes and get medical attention right away.
2.10 If battery acid is accidentally swallowed, drink milk, the whites of eggs or water. DO NOT
induce vomiting. Seek medical attention immediately.
3. PREPARING TO CHARGE
WARNING
WARNING
RISK OF CONTACT WITH BATTERY ACID. BATTERY ACID IS A
HIGHLY CORROSIVE SULFURIC ACID.
3.1 If it is necessary to remove the battery from the vehicle to
charge it, always remove the grounded terminal rst. Make sure all
of the accessories in the vehicle are off, to prevent arcing.
3.2 Be sure the area around the battery is well ventilated while the battery is being charged.
3.3 Clean the battery terminals before charging the battery. During cleaning, keep airborne
corrosion from coming into contact with your eyes, nose and mouth. Use baking soda and
water to neutralize the battery acid and help eliminate airborne corrosion. Do not touch
your eyes, nose or mouth.
3.4 Add distilled water to each cell until the battery acid reaches the level specied by the
battery manufacturer. Do not overll. For a battery without removable cell caps, such as
valve regulated lead acid batteries (VRLA), carefully follow the manufacturer’s recharging
instructions.
3.5 Read, understand and follow all instructions for the charger, battery, vehicle and any
equipment used near the battery and charger. Study all of the battery manufacturer’s
specic precautions while charging and recommended rates of charge.
3.6 Determine the voltage of the battery by referring to the vehicle owner’s manual and make
sure that the output voltage selector switch is set to the correct voltage. If the charger has
an adjustable charge rate, charge the battery in the lowest rate rst.
3.7 Make sure that the charger cable clips make tight connections.
