AGM construction improves charge acceptance and vibration resistance, supports start-stop and regenerative braking, and offers low self-discharge with maintenance-free operation.
Seven-stage cold rolling and blanking grid process delivers higher mechanical strength and stable conductivity for dependable power output.
AGM-specific paste with negative lead-carbon modification reduces sulfation and electrolyte stratification, providing >3× cycle life vs. common starter batteries.
No free electrolyte—minimizing leakage risk. Sealed and maintenance-free for varied environments.
Robust capacity and strong charge acceptance enable efficient short-time fast charging.
Low internal resistance supports excellent cold cranking performance in severe weather.
Compact assembly limits active material shedding, stabilizing deep-cycle performance and extending service life.

European, American, and Japanese vehicles equipped with start-stop and energy recuperation, suited for urban conditions.
Vehicles with higher electrical loads needing reliable starts and fast recharge efficiency across mixed duty cycles.
Verify the battery model (H3–H9) matches the vehicle specification and OEM requirement.
Inspect the battery for no visible damage, leakage, or deformation before installation.
Check vehicle charging system voltage: should regulate within 13.5V – 14.8V for AGM.
Ensure the ignition is OFF and remove the negative terminal first.
Clean battery tray, terminals, and connectors from corrosion or dirt.
Place the AGM battery securely in the tray to prevent vibration during operation.
Connect positive terminal first, then negative. Tighten all connections firmly to avoid voltage drop.
Confirm all vehicle settings (start-stop system, BMS if equipped) are properly reset or re-coded according to OEM instructions.
After installation, allow the alternator or an AGM-compatible charger to bring the battery to full charge before heavy use.
Perform a system check to ensure the start-stop function, dashboard electronics, and accessories operate normally.
Avoid leaving the vehicle unused for long periods; AGM batteries perform best when kept at a healthy charge level.
If stored or not in use, recharge the battery every 2–3 months to prevent deep discharge.
Use only AGM-compatible intelligent chargers for maintenance charging.
Do not attempt to open or refill the battery — AGM is sealed and maintenance-free.
Avoid short-circuiting terminals during installation or service.
Handle with care and use protective equipment during installation (gloves, safety glasses).
Ensure proper ventilation when charging.
For fleets, implement a preventive maintenance schedule: battery condition checks every 6–12 months.
Use professional battery testers to monitor voltage, CCA, and internal resistance.
Replace AGM batteries proactively in high-mileage vehicles to avoid unplanned downtime.
Store fully charged batteries in a cool, dry environment.
Recommended storage temperature: 0°C – 25°C.
Self-discharge rate is low (<8% at 25°C over 90 days), but periodic recharging is advised.
Always transport batteries upright, secured on pallets, with protective packaging.
