The maintenance-free design eliminates the need for regular water checks or top-ups—thanks to the Calcium-Calcium technology that minimizes electrolyte evaporation. For OEMs, this translates to fewer post-sales support requests and higher customer satisfaction, as end-users avoid the hassle of routine battery upkeep.
With an operating temperature range of -15°C to 40°C (discharge), the battery performs reliably in both cold winters and warm summers. Its robust construction resists vibration and impact, making it suitable for OEMs supplying products to regions with extreme weather or rough terrain.
Beyond standard specs, the battery offers flexible customization to align with OEM branding and product needs:
Custom logos printed on battery covers for brand consistency.
Adjustable capacity/size options to fit unique machinery or vehicle designs.
Tailored packaging for bulk shipping, reducing transit damage and streamlining logistics.
The combination of Calcium-Calcium technology and a sealed structure extends the battery’s lifespan compared to traditional lead-acid alternatives. For OEMs, this means lower warranty claim rates and a competitive edge in markets where long product life is a key buyer priority.
To meet the strict requirements of global OEMs, the Lead Acid High Performance Maintenance Free Car Battery holds industry-leading certifications, ensuring quality, safety, and compliance:
ISO9001: Validates adherence to international quality management systems, from raw material testing to final production.
ISO14001: Confirms eco-friendly manufacturing processes, reducing environmental impact—critical for OEMs targeting sustainability-focused markets.
IATF16949: Automotive-specific certification, guaranteeing compliance with rigorous automotive OEM quality standards.
SABER: Facilitates access to Middle Eastern markets by meeting regional regulatory requirements.
Backed by 20+ years of battery manufacturing experience from JUJIANG POWER, each battery undergoes 3+ quality checks (including voltage testing, leak detection, and durability trials) before leaving the factory—ensuring consistent performance for OEM clients.

Yes. While designed for cars, the battery’s 12V/45Ah output and durable build make it suitable for small-to-medium industrial generators, forklifts, and other machinery. We offer custom capacity adjustments to match specific power needs for non-automotive OEMs.
For bulk orders, we offer:
• Dedicated technical support teams to advise on battery integration into OEM products.
• Competitive bulk pricing to reduce per-unit costs.
• Flexible lead times to align with OEM production schedules.
Yes. We provide a standard 12-month warranty for OEM orders, with extended warranty options available. Warranty coverage includes defects in materials or manufacturing—protecting OEMs from unexpected replacement costs.
While AGM/EFB batteries excel in start-stop vehicles, our lead-acid maintenance-free battery offers a more cost-effective solution for OEMs needing reliable power in standard vehicles or machinery. It also requires less specialized charging equipment, reducing end-user complexity.
