The VRLA battery is one of many types of leadacid batteries. In a VRLA battery the hydrogen and oxygen produced in the cells recombine back into water. In this way there is no leakage.
Since VRLA batteries do not require (and make impossible) regular checking of the electrolyte level, they have been called Maintenance Free (MF) batteries.
Valve Regulated Lead Acid rechargeable batteries are designed to provide outstanding performance in withstanding overcharge, over discharge, and resisting vibration and shock.
Compact, these batteries save installation space, while providing full and reliable power. The use of special sealing epoxies, tongue and groove case and cover construction, and longsealing paths for posts and connectors, assures that the Valve Regulated Lead Acid battery will offer exceptional leak resistance, and allows them to be used in any position.
Features:
1. Higher Reliability and Quality. Throughout the whole manufacturing process, PPM and ISO 9001 are carried out to make sure that the product reliability and defect ratio meet with the PPM standard.
2. Higher Power Density . A special assembly technology is used to enhance power density to a considerable level.
3. Reliable Construction.The extra strong construction ABS container reduces case bulging and plate warping, ensuring long life and high performance.
4. Valve regulating. Perfect venting system, which operates under low pressure, is designed to release excess gas and keep the internal pressure within the optimum range of safe and efficient performance.
5. Excellent Recovery from Deep Discharge. Unique technical processes are used into the grid alloy and electrolyte additives, so that the battery can be recharged easily to a normal level even after being over-discharged.

Maintenance & Cautions:ions:ions:
1,Float Service:
Every month, recommend inspection every battery voltage.
Every three months, recommend equalization charge for one time.
2,Equalization charge method:
Discharge: 100% rate capacity discharge.
Charge: Max. current 0.3CA, constant voltage 2.4-2.45V/Cell charge 24h.
3,Effect of temperature on float charge voltage: -3mV/ºC/Cell./Cell./Cell.
4,Length of service life will be directly affected by the number of discharge
cycles, depth of discharge, ambient temperature and charging voltage.
