• Multi-angle Use: Can be used in any direction (side, horizontal, upside down) for 48 hours without leakage.
• Deep Discharge Design: Residual capacity remains ≥ 50% after 96 cycles of 100hr full capacity life.
• Superior Storage: Remains functional after 2 years of full storage or 120 days at 50% SOC.
• Fast Recovery: Recovers to over 95% capacity after being discharged to 0V and short-circuited for 3 days.
• Standards: Fully compliant with RoHS and REACH EU Battery Directives.

What is a Valve-Regulated Sealed Lead-Acid Battery (VRLA)?
A VRLA battery is a sealed lead-acid battery using internal oxygen recombination technology for maintenance-free operation. It includes a safety valve to prevent pressure buildup. Types include AGM and Gel.
How is VRLA different from conventional flooded batteries?
VRLA batteries are sealed and maintenance-free, requiring no water refilling. They allow for flexible installation directions and minimize gas emissions through oxygen recombination.
Does a VRLA battery require an initial charge?
They come pre-charged. however, if stored for more than 6 months, a supplementary charge is recommended using constant voltage charging.
What is the correct charging voltage for a 12V battery?
For cycle use, it is 14.4-14.8V; for float charge, it is 13.6-13.8V. Always follow specific manufacturer guidelines to avoid water loss.
How to determine if a battery is at its end-of-life?
Replace if capacity falls below 60% of the rated value, or if voltage drops rapidly (below 12.0V for a 12V unit) after a full charge.
How should I store an unused VRLA battery?
The battery should be fully charged before being placed into storage to maintain its health and service life.
