2V 250 Ah Tubular OPzS Battery for Telecommuication/Photovoltaic Application with 20 years LifeSpan

EverExceed tubular OPzS Range series batteries are 20 year stationary batteries and were developed for utility, telecom and general purpose applications. They are distinguished by their economical design, lead selenium tubular plate design, and their high tolerance to cycling.

The EverExceed tubular lead selenium cells provide the best possible compromise in lead acid plate technology. By utilizing a proportion of selenium in the grid alloy, a dense fine grain structure is produced. This alloy is extremely corrosion-resistant and virtually eliminates inter-granular corrosion-one of the most common causes of cell failure. A lead selenium cell, therefore, combines the advantages of both lead calcium and lead antimony cells while exhibiting none of the disadvantage.

Applicable Operating temperature range:
-40°C(-40°F) to +70°C (+158°F)
Ideal Operating temperature range:
+20°C (+68°F) to +35°C (+95°F)
Storage time from a fully charged condition:
12 months at 20°C~25°C / 68°F~77°F.
Could up to 5 years if in sealed dry charged condition.
For each 9°C / 15°F rise, reduce the storage time by half.

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.
