Leoch golf cart battery

can be used for all electrically powered industrial trucks, cleaning machines, lifting platforms,

AGV systems. They are particularly indispensable in sensitive areas like hospital and food market. Due to improved

resistance to low temperatures,

is also superior to conventional lead-acid batteries in cold

areas such as cold stores.

have a long service life and more economical.

Throughout the worldwide,

are regarded as the most environmentally friendly lead-acid

battery system. With the selection of special alloys and other materials, consideration is given to the environment

even at battery development stage. At the end of the battery's service life, the batteries can be collected and

properly disposed. Lead and plastics are recycled and returned to the production process.

GENERAL INFORMATION

APPLICATION FOR GOLF BATTERIES

CONVENTIONAL FLOODED BATTERIES

Higher capacity and higher energy density.

Longer service life.

Excellent deep cycle property.

Unique alloy and paste recipe for deep cycle application.

Refilling plugs with special construction guarantee less water consumption.

S pecial separator in nano grade.

Advanced TTP welding and heat sealing technology.

Terminals with high conductivity are very good at high current discharging.

Containers and lids are impact resistant and made of polypropylene(PP).

Wider operation temperature, safe and reliable.

What is gel?

Gel is usually produced by homogeneous dispersion of pyrogenic silica in a diluted sulfuric acid. Pyrogenic silica is a

powder of very fine dispersed SiO

which can absorb more than 10 times of its weight liquids, producing gel. Because of

the thixotropic properties of gel (liquid by stirring and solid by resting), after a certain gelling time, the agglomerates are

connecting themselves together to form a network which kept the liquid inside and gives the gel structure. This form can

be again broken by stirring to single agglomerates giving again a liquid form.

ADVANTAGES OF TUBULAR GEL BATTERIES

No electrolyte adjustment needed.

No periodical recharging is needed during storage because of low self discharge.

Do not need quick recharging after discharging.

Deep discharging resistance.

No antimony poisoning by overcharging.

Extremely low gas extrication during charging.

High float-and cycle-life because of using gel and tubular plates.

High energy at low temperatures.

Can be stored and used in any position as there is no electrolyte spilling.

The concept of gel can be used by tubular plates (AGM is not easy).

No pollution problems if container is damaged.

Approved for air Transport (IATA).

No Acid stratification (segregation).

No thermo-runaway-effect .

Deep discharge properties are much less in case of gel than by AGM.

Using gel SOL as electrolyte.

Using the extra microporous separator which can: reduces the depolarization of the negative electrode and

avoids the PCL.

3 effect (premature capacity loss due to negative plate sulphation); significantly decreases thermal runaway;

during deep discharge or pole reversal, helps to prevent short circuits by dendrite growth between the plates.

Plate thickness tolerance is not critical since the high compression of plate group assembly is not required.

More electrolytes for better contact with plates and active materials and container walls, good for releasing

internal heat and cooling battery temperature.

Better vent valve design to lower gassing rate and water losing rate to extend battery lifetime.

Maintenance free,not need check the height of electrolyte periodically and add distilled water.
