STORAGE

Batteries should be stored in dry and clean warehouse which has good air exchange system. Batteries should avoid direct sunlight. Batteries should not be near to heat (such as radiator, the distance should more than1m). Batteries should avoid any toxic gas and organic solvent.

When the ambient temperature is less than 25, the longest storage life is 6 months. If ambient temperature is higher, the longest storage life varies as specified in below chart.

Batteries should be recharged within the storage life or before using.

Charging methods: maximum charging current 8A, constant voltage 2.45±0.05V/cell (25);

Charging time: 15~20h; Temperature compensation coefficient: -5mV//cell.

FAQ

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 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.
