PRODUCT. Failure to follow these safety instructions may result in ELECTRICAL
SHOCK, EXPLOSION, FIRE, which may result in a SERIOUS INJURY, DEATH, or
PROPERTY DAMAGE.
Electrical Shock. Product is an electrical device that can shock and cause serious
injury. Do not cut power
cords. Do not submerge in water or get wet.
Explosion. Unmonitored, incompatible, or damaged batteries can explode if used with
product. Do not leave product unattended while in use. Do not attempt to jump start a
damaged or frozen battery. Use product only with batteries of recommended voltage.
Operate product in well ventilated areas.
Fire. Product is an electrical device that emits heat and is capable of causing burns. Do
not cover product.
Do not smoke or use any source of electrical spark or fire when operating product.
Keep product away from
combustible materials.
Eye Injury. Wear eye protection when operating product. Batteries can explode and

manufacturer and manufacturer of any equipment intended to be used
in the vicinity of battery. Review cautionary markings on these products and on engine.
IMPORTANT SAFETY WARNINGS
The VEVOR GS450C.represents some of the most innovative and advanced
technology on the market, making each charge simple and easy. It is quite
possibly the safest and most efficient charger you will ever use. The GS450C. is
designed for charging all types of 6V & 12V & 24V lead-acid batteries, including
Lithium ,LiFePO4, Wet (Flooded), Gel, MF (Maintenance-Free), CA (Calcium),
EFB (Enhanced Flooded Battery), and AGM (Absorption Glass Mat) batteries. It is
suitable for charging battery capacities up to 600 Amp-Hours and maintaining all
battery sizes. Getting Started. Before using the charger, carefully read the battery
manufacturer’s specific precautions and recommended rates of charge for the
battery. Make sure to determine the voltage and chemistry of the battery by
referring to your battery owner’s manual prior to charging. Mounting. It is important
to keep in mind the distance to the battery. The DC cable length from the charger,
with either the battery clamp or eyelet terminal connectors, is approximately 47.2
inches (1200mm).Proposition 65. Battery posts, terminals, and related
accessories contain chemicals, including lead. These materials are known to the
State of California to cause cancer and birth defects and other reproductive harm.
Personal Precaution. Only use product as intended. Someone should be within
range of your voice or close enough to come to your aid in case of emergency.
Have a supply of clean water and soap nearby in the case of battery acid
contamination. Wear complete eye protection and protective clothing while
working near a battery. Always wash hands after handling batteries and related
materials. Do not handle or wear any metal objects when working with batteries
including; tools, watches or jewelry. If metal is dropped onto battery, it may spark
or create a short circuit resulting in electrical shock, fire, explosion which may
result in injury, death or property damage. Minors. If the product is intended by
“Purchaser” to be used by a minor, purchasing adult agrees to provide detailed
instructions and warnings to any minor prior to use. Failure to do so is the sole

Connecting to the Battery.
Do not connect the AC power plug until all other connections are made.
Identify the correct polarity of the battery terminals on the battery. Do not
make any connections to the carburetor, fuel lines, or thin, sheet metal
parts. The below instructions are for a negative ground system (most
common). If your vehicle is a positive ground system (very uncommon),
follow the below instructions in reverse order.
1.) Connect the positive (red) eyelet terminal connector to the positive
(POS,P,+) battery terminal.
2.) Connect the negative (black) eyelet terminal connector to the negative
(NEG,N,-) battery terminal.
3.) Connect the battery charger into a suitable electrical outlet. Do not face
the battery when making this connection.
4.) When disconnecting, disconnect in the reverse sequence, removing the
negative first (or positive first for positive ground systems).
Begin Charging.
1.) Verify the voltage and chemistry of the battery.
2.) Confirm that you have connected the battery clamps or eyelet terminal
connectors properly and the AC power plug is plugged into an electrical
outlet.
3.) [First time use] The charger will begin in Standby mode, and pause will
be circled by blue . In Standby, the charger is not providing any power.
4.) Press the key battery type to select batteries,secondly press the key
Voltage,thirdly press the key Current.
5.) Press the key Start and it will be lined by blue,secondly the battery will
be detected.If the battery is normal,no battery indicator will lose and the
charger will work normally, or reversly.
6.) The charger can now be left connected to the battery at all times to
provide maintenance charging.
Auto-Memory: The charger has built in auto-memory and will return to the
last charge mode when connected. Select suitable mode and press the key
Start and then the charger will save new working mode.
Caution:Professional Mode can’t Auto-Memory.
CHARGING TIMES.
Charging Times.
The estimated time to charge a battery is shown below. The size of the
battery (Ah) and its depth of discharge (DOD) greatly affect its charging
time. The charge time is based on an average depth of discharge to a fully
charged battery and is for reference purposes only. Actual data may differ
due to battery conditions. The time to charge a normally discharged battery
is based on a 50% DOD. Temperature will also impact charging times.
GS450C features thermal compensation that automatically adjusts
charging profiles to maximize charging performance.
