Beleeb Pulses of High-Voltage Automatic Battery
Charger 12V 24V 36V 48V 60V 72V
Why choose Beleeb Series versatile battery charger?
Desulfation is particularly important for applications, such as solar arrays or electric wheelchairs, that don't often allow for
a complete charging cycle. The interrupted charging cycles common in these applications can lead to extensive sulfation
within the battery, causing premature battery death.
However, a new technology called battery desulfation promises to help extend the life of lead-acid batteries. This technology
uses specialized equipment to send periodic frequency-based pulses and/or pulses of high-voltage electricity through the
battery, helping to break up these hardened sulfate crystals over the course of many days. By breaking up the sulfate crystals,
battery desulfation allows the lead dioxide plates to regain their full functionality, increasing the potential current that can
be generated within the battery. When used correctly, this desulfation technology can restore functionality to worn-out
batteries and extend the useful lifespan of fresh batteries.
By extending battery life, Beleeb series battery charger is designed to charge and maintain 12V 24V 36V 48V 60V 72V lead-
acid and lithium-ion batteries, including flooded, gel, AGM, and deep-cycle batteries.

INTRODUCTION
Beleeb chargers use an isolation transformer as a step-down unit, this isolation transformer converts high-voltage, low-current power
into low-voltage, high-current power. A bridge rectifier converts mains AC input to pulsating DC output. And CPU is used to control
the output voltages and current.
They can be used on batteries of differing types, including power batteries, capacity batteries, start-up batteries. Or they can be used
in a 12, 24, 36, 48, or 72 volt system using a combination of 6,8,12 volt lithium-ion or lead-acid batteries. Beleeb battery chargers will
handle their own charging and stop when full charged . Therefore there's no need for a person to be on duty.
They also have devulcanization repair and equalization mode, equalizing charge can compensate for the unbalance between
batteries, which lengthens the life of batteries.
1. Beleeb series battery chargers are designed for charging various voltage battery packs (12V/24V/36V/48V/60V/72V). The voltage
output is critical and must match your battery pack.
2. The charger's output current is adjustable, and the internal protection circuit will limit the max charging current to prevent overload.
Charging speed will differ based on a charger amperage. Pick the charger amperage and charging speed that’s right for your batteries.
3. They are equipped with both normal and equalizing charge modes. The normal charging mode is used to charge the battery daily,
and the deep charging mode can desulfurize and equalize the battery through pulse high voltage.
IMPORTANT SAFETY INSTRUCTIONS
1. SAVE THESE INSTRUCTIONS.
Read all instructions, warnings, and cautions printed on the battery charger, battery, and vehicle or equipment using the
battery.
DO NOT expose the charger to rain or snow.
Use of an attachment not recommended or sold by the battery charger manufacturer may result in a risk of fire, electric
shock, or injury to persons.
To reduce the risk of damage to the electric plug and cord, pull by plug rather than cord when disconnecting charger.
An extension cord should not be used unless absolutely necessary.
The use of an improper extension cord could result in a risk of fire and electric shock.
DO NOT operate charger with a damaged cord or plug—replace the cord or plug immediately.
DO NOT operate charger if it has received a sharp blow, been dropped, or otherwise damaged in any way—take it to a
qualified serviceman.
DO NOT disassemble the charger. Take it to a qualified service professional if service or repair is required. Incorrect assembly
may result in fire or electric shock.
To reduce the risk of electric shock, unplug the charger from the outlet before attempting any maintenance or cleaning.
Turning off controls will not reduce this risk.
2. WARNING—RISK OF EXPLOSIVE GASES.
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.
To reduce the risk of battery explosion, follow these instructions and those published by the battery manufacturer and
manufacturer of any equipment you intend to use in the vicinity of the battery.
Review cautionary markings on these products and on the engine.
3. PERSONAL SAFETY INSTRUCTIONS.
Consider having someone close by coming to your aid when you work near a lead-acid battery.
Have plenty of fresh water and soap nearby in case battery acid contacts skin, clothing, or eyes.
Wear complete eye protection and clothing protection. Avoid touching eyes while working near the battery.
If battery acid contacts skin or clothing, wash immediately with soap and water. If acid enters the eyes, immediately flood
the eyes with running cold water for at least 10 minutes and get medical attention immediately.
NEVER smoke or allow a spark or flame in the vicinity of the battery or engine.
Take extra precautions to avoid dropping a metal tool onto the battery. It may spark or create a short circuit that can cause
an explosion.
Remove 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-circuit current high enough to weld a ring or the like to metal, causing a severe burn.
Use the charger for charging a LEAD-ACID and LITHIUM-ION battery only. It is not intended to supply power to a low voltage
electrical system other than in a starter-motor application. Do not use the battery charger for charging dry-cell batteries that
are commonly used with home appliances. These batteries may burst and cause injury to persons and damage to property.
NEVER charge a frozen battery.
4. PREPARING TO CHARGE
If it is necessary to remove the battery from the vehicle to charge, always remove the grounded terminal from the battery
first. Make sure all accessories in the vehicle are off so as not to cause an arc.
Be sure the area around the battery is well ventilated while the battery is being charged.

WARNING: A SPARK NEAR THE BATTERY MAY CAUSE A BATTERY EXPLOSION. TO REDUCE THE RISK OF A SPARK NEAR THE
BATTERY:
Position AC and DC cords to reduce the risk of damage by the hood, door, or moving engine part.
Stay clear of fan blades, belts, pulleys, and other parts that can cause injury to persons.
Check the polarity of battery posts. POSITIVE (POS, P, +) battery post usually has a larger diameter than NEGATIVE (NEG, N,
-) post.
Determine which post of battery is grounded (connected) to the chassis.
If the negative post is grounded to chassis (as in most vehicles), see the step "For negative-grounded vehicle". If the positive
post is grounded to the chassis, see the step "For positive-grounded vehicle".
For a negative-grounded vehicle, connect POSITIVE (RED) clip from battery charger to POSITIVE (POS, P, +) ungrounded post
of the battery. Connect NEGATIVE (BLACK) clip to vehicle chassis or engine block away from the battery. Do not connect the
clip to carburetor, fuel lines, or sheet-metal body parts. Connect to a heavy-gauge metal part of the frame or engine block.
For a positive-grounded vehicle, connect NEGATIVE (BLACK) clip from battery charger to NEGATIVE (NEG, N, -) ungrounded
post of the battery. Connect POSITIVE (RED) clip to vehicle chassis or engine block away from the battery. Do not connect
the clip to carburetor, fuel lines, or sheet-metal body parts. Connect to a heavy-gauge metal part of the frame or engine
block.
When disconnecting the charger, turn the switch off, disconnect the AC cord, remove the clip from the vehicle chassis, and
then remove the clip from the battery terminal.
FOLLOW THESE STEPS WHEN THE BATTERY IS OUTSIDE THE VEHICLE
WARNING: A SPARK NEAR THE BATTERY MAY CAUSE A BATTERY EXPLOSION. TO REDUCE THE RISK OF A SPARK NEAR THE
