2015 Wholesale EverExceed Low Maintenance SEBL Railway storage battery

This series of rechargeable battery is specially designed and developed for various operation environment conditions. Which not only has the characteristic of traditional batteries, but also the advantage of maintenance ultra-low. It is especially applied to electric power, telecommunication, railway, metallurgy, mining, lighting, UPS power supply and other devices as standby power supply, diesel engine and direct motor as starting power supply, and transportation tools as direct power supply.

Low maintenance

High performance
The battery adopts the optimized design, which can produce high performance battery, and can be applied under the
temperature of -50oC~70oC(58°F~ 158°F). The service life can be more than 20 years according to the recommended maintenance and operation methods.
High float-charge efficiency
The battery adopts high performance positive and negative active materials, improving the charging efficiency of positive and negative electrodes, reducing the float-charge voltage of the battery, under the lower float charge voltage;
The consumes capacity of the battery will be highly recovered. After being float charged for 16h by 1.41V/cell ±0.01V/cell, the battery can be discharged by 80% of the rated capacity.

Valve-regulated vent plug with low pressure and fire prevention is in stalled on the battery. If its internal pressure is beyond the safety value, the hydrogen and the oxygen not combined by the negative pole are released through the valve of valve-regulated vent plug and the normal operating pressure is 0.2 bar; when the pressure falls below the releasing pressure, the valve of valve-regulated vent plug will re-close to prevent air entering, avoiding carbonatization of the electrolyte.

Q: What is an AGM battery?

A: An AGM battery is a lead-acid battery that is sealed using special pressure valves and completely maintenance-free. It has all of its electrolyte absorbed in separators consisting of a sponge-like mass of matted glass fibers, and uses a recombination reaction to prevent the escape of hydrogen and oxygen gases normally lost in a flooded lead-acid battery (particularly in deep cycle applications).

Q: What is a GEL battery?

A: A gel battery is a lead-acid battery that is sealed using special pressure valves and completely maintenance-free. It uses thixotropic gelled electrolyte and uses a recombination reaction to prevent the escape of hydrogen and oxygen gases normally lost in a flooded lead-acid battery (particularly in deep cycle applications).

Q: What is a NiCad Battery?

A: The nickel cadmium battery is a type of rechargeable battery using nickel oxide hydroxide and metallic cadmium as electrodes. EverExceed manufactures pocket plate and sintered plate nicad batteries.

Q: What is battery rating?

A: The most common battery rating is the Ampere-hour Rating. The capacity of a battery, in Ahs, is a dynamic number that is dependent on the discharge current.For example: 10 amperes for 20 hours (10 x 20) = 200 Ah @ the 20-hour rate.

Q: How can you tell if a VRLA battery has been damaged by under- or overcharging?

A: The only way is with a load test. Use the same procedure you would use with a wet cell battery:

a. Recharge if the open circuit voltage is below 75%.

b. If adjustable, set the load at 1⁄2 the CCA rating or three times the 20 hour rate.

c. Apply the load for 15 seconds. The voltage should stabilize above 9.6 volts while on load.

d. If below 9.6 volts, recharge and repeat test.

e. If below 9.6 volts a second time, replace the battery.

Q: How long does it take to recharge a fully discharged VRLA battery?

A: A specific time is difficult to determine because recharging depends on the following factors: depth of discharge; temperature; size and efficiency of the charger; age and condition of the battery.

Q: How do I select the right battery for my applications?
A: Proper battery selection may require the assistance of a knowledgeable battery sales or service technician. Please consult EverExceed for more details.
