FAQ

• Q

  Safe Installation Guidelines?​

  A

  Installation Location Requirements:

  •Dry & ventilated area (recommended: in the distribution room or compartment)

  •Avoid high-humidity engine room bilges

  •≥50cm clearance from heat sources (engines/exhaust pipes)

  •IP67 waterproof but avoid direct spray exposure or soaking in water

• Q

  Can Lilead Dual-Use Batteries be installed tilted?​

  A

  Yes, Lilead Dual-Use Batteries has advanced internal fixation structure, so they can be installed horizontally or tilted at any angle.
• Q

  Can lithium Start Batteries Function as Deep-Cycle?​

  A

  Yes. Lithium start batteries are dual-purpose, which provide high cranking currents and Support deep-cycle applications (requires DC-DC converter for optimal equipment protection).
• Q

  Yes. Lithium start batteries are dual-purpose, which provide high cranking currents and Support deep-cycle applications (requires DC-DC converter for optimal equipment protection)​

  A

  No. Series Connection is prohibited when Lithium batteries are used as starter batteries.  They must only be paralleled, never series-connected for cranking applications.

  Only when the battery is used for deep cycling can it be used in parallel. Please refer to the battery specification sheet for specific details.

• Q

  Engine Compatibility?​

  A

  LILEAD batteries are compatible with the vast majority of marine engines, including YANMAR, Weichai, MAN, CAT, MTU, VOLVO PENTA, etc.

  Under room temperature conditions:

  •12V Cranking Batteries (S110, S200) can support 12 consecutive starts of a 12V 3.5kW starter motor.

  •24V Cranking Battery (S24110) can support 12 consecutive starts of a 24V 8.5kW starter motor.

  LILEAD batteries serve as direct drop-in replacements for lead-acid cranking batteries.
• Q

  Storage conditions:​

  A

  Temperature：0-35°C

  Relative Humidity：≤60%

  State of Charge：30%-50% SOC

  Maintenance action: Every 3 months, Charge battery at 0.2-0.5C and discharge at 0.2-0.5C ,then Recharge to 40% SOC at 0.5C.

• Q

  What types of motorcycles are the MC series batteries suitable for?​

  A

  The MC7, MC14, and MC30 series batteries are designed for motorcycles and marine use, compatible with most fuel-powered motorcycles, off-road bikes, ATVs, and small watercraft. For specific compatibility, please refer to your vehicle manual or consult our customer service.
• Q

  What is the "Vibration Wake-up Function"?​

  A

  When the motorcycle remains unused for an extended period, the battery automatically enters sleep mode to conserve power. The vibration wake-up function detects movement (such as touching or starting the vehicle) and instantly reactivates the battery, ensuring immediate power availability.
• Q

  What is the purpose of the “30% power protection” indicated on the MC series batteries?​

  A

  This feature prevents over-discharge by automatically cutting off power when the battery level drops below 30%, effectively extending battery life and avoiding damage caused by deep discharge.
• Q

  What do the certifications (CE/UN38.3) mean?​

  A

  Lithium-ion batteries entering the EU market must obtain CE certification to comply with the European Union's Battery Regulation and relevant safety/environmental standards, serving as a mandatory pass for access to the EU/European Economic Area; UN38.3, the globally mandated transport safety certification, is a required test for air/sea shipments of lithium batteries, verifying their stability during transport.
