| High reliability, safe without leakage. Can be operated in any orientation. |
| Excellent start ability at low temperature. High current discharge is tested at -18°C and -5°C can be discharged continuously for more than 30 seconds |
| Good cycle life of high current discharge. After continuous 200 cycles of high current discharge, almost no attenuation of discharge time. |
| Excellent storage performance. After being fully charged and stored for 6 months without affecting the vehicle's ability to start in case of emergency. |
KaiYing Power Supply & Electrical Equip Co., Ltd. (LONGWAY Battery) was established in 2000 and currently has two major production plants with the factory area of over 100,000 m2, over 1000 employees, and an annual production capacity of over 2 million KVAH. Since its establishment, we have been committed to the development and production of high-quality battery products. Focusing on research and development, we are committed to the production, sales, and services of AGM battery and GEL battery.
Q: What is a Valve-Regulated Sealed Lead-Acid Battery (VRLA)?
A: A VRLA battery is a sealed lead-acid battery that utilizes internal oxygen recombination technology (oxygen recombines at the negative plate to form water) for maintenance-free operation. It is equipped with a safety valve to prevent excessive pressure buildup. There are two types: AGM (Absorbent Glass Mat) and Gel.
Q: How is a VRLA battery different from a conventional flooded lead-acid battery?
A: Sealed & Maintenance-Free: No water refilling is needed; the electrolyte is absorbed (AGM) or gelled (Gel).Oxygen Recombination: Minimizes gas emissions and allows horizontal installation (though upright is recommended).Safety Valve: Releases excess pressure to prevent swelling.
Q: Does a VRLA battery require an initial charge?
A: It comes pre-charged, but if stored for over 6 months, a supplementary charge is recommended before use (use constant voltage charging as per the manual).
Q: What is the correct charging voltage?
A:For 12V Batteries:Cycle Use: 14.4-14.8V (lower for Gel batteries).Float Charge: 13.6-13.8V (to maintain charge without overcharging).Always follow the manufacturer's specifications-excessive voltage can cause water loss or thermal runaway.
Q: How to determine if a battery is end-of-life?
A: Replace if:Capacity drops below 60% of the rated value.Voltage drops rapidly after a full charge (e.g., s12.0V for a 12V battery at rest).Internal resistance increases significantly (requires specialized equipment).
Q: How to store an unused VRLA battery?
A:Fully charge before storage.
