  • Question:What is Cut-Off Voltage/End Point Voltage?
    Answer:EPV( End Point Voltage) is the battery end load voltage in the condition of discharge. Many kinds of standards rule EPV definitely in different discharge rates and temperatures. EPV is different according to different discharge rates: it is low when discharge in high current, contrarily, it is high when discharge in low current.
  • Question:How to recovery the performance after long storage?
    Answer:Normally you may not get 100% performance back after storage during the first recharge. That means those batteries may need more than one recharge cycle. Please discharge then rechargefor 3 cycles.
  • Question:What is “over-discharge” and what is it’s effect o?
    Answer:If the final voltage is lower than the standard final voltage, we can say the battery is “over-discharged.” The state will affect the battery’s life very seriously.1.The “over discharge” state will cause overuse of active material. The composition of the battery will be changed by the over discharge. There will be degradation of the plate.2.It may bring out too much or large amounts of lead sulfate (PbSO4) which could cause damage to the plate structure. A recharge may not bring the full performance of the battery back.3.Recharging after over discharging may lead to short failures.
  • Question:What is the definition of “cycle use” and “standby?
    Answer:“Cycle Use” – direct power source:It can provide the power supply to power tools, portable electronic products. It can also be used for cycling charging and discharging usage such as electronics motorbike or vacuum cleaner. “Standby Use” – back up power:Mainly used for emergency power to avoid future damage that may be caused by a sudden power outage.
  • Question:Types of Charging?
    Answer:(1) Float/StandbyThis charging method is used in applications such as emergency back-up when the battery is required only upon mains failure e.g., continuously on charge and consequently the recommended voltages are slightly lower than cyclic charging so as not to damage the battery. (2) CyclicCyclic charging is used in applications where the battery is repeatedly discharged then charged, e.g. Portable equipment, Wheel Chairs, Golf trolleys etc.A higher charging voltage is used but should NEVER be left on indefinitely since it will overcharge and destroy the battery.
  • Question:What’s VRLA battery?
    Answer:A VRLA battery, valve-regulated lead–acid battery, is a lead–acid rechargeable battery. Because of their construction, VRLA batteries do not require regular addition of water to the cells, and vent less gas than flooded lead-acid batteries. The reduced venting is an advantage since they can be used in confined or poorly ventilated spaces. VRLA batteries are commonly further classified as: Absorbed glass mat (AGM) battery has the electrolyte absorbed in a fiber-glass mat separator. Gel battery has the electrolyte mixed with silica dust to form an immobilized gel. The name "valve regulated" does not wholly describe the technology. These are really "recombinant" batteries, which means that the oxygen evolved at the positive plates will largely recombine with the hydrogen ready to evolve on the negative plates, creating water and preventing water loss. The valve is a safety feature in case the rate of hydrogen evolution becomes dangerously high.
  • Question:What's the application of VRLA battery?
    Answer:UPS, Marine, Robotics, Telecom Communication Utility, Alarm system, Security Equipment, Medical Equipment, Electronic Test Equipment, Portable Television & Video Equipment, Power Tools, Solar Power Lighting, Toy Vehicles, Wheelchair, Golf Trolleys, Semi-traction Lawn Mowers, Lifting Equipment
