What is the wholesale price range for 12V 18Ah lithium batteries?
Wholesale prices vary from $20-$50/unit based on quality. Grade A cells with CE certification cost $35-$50, while basic models start at $20. Bulk orders (100+) often qualify for additional 15% discounts.

What's the MOQ for 12V 18Ah battery bulk orders in China?
Minimum orders typically start at 50 units, though some factories accept 20 units for first-time buyers. Established relationships can negotiate 10-unit trial orders with higher per-unit costs.

Technical Specifications

What are the key technical specifications?
Standard specs include 18Ah capacity, 2000+ cycles, and -20°C to 60°C range. Dimensions average 7×5×3 inches with 3-5kg weight. Features overcharge protection and short-circuit prevention via integrated BMS.

How long does a 12V 18Ah lithium battery last?
Lifespan averages 5-8 years with daily use (2-3 cycles/week). Capacity remains above 80% for 1500+ cycles when properly maintained. Storage at 50% charge extends calendar life.

What is the charging time for 12V 18Ah lithium batteries?
Full charges take 2-3 hours using 10A chargers. Fast charging (15A) reduces to 1.5 hours but may slightly decrease long-term cycle life. Built-in BMS prevents overcharging damage.

Certifications & Safety

Are 12V 18Ah lithium batteries certified for international export?
Export-ready models carry CE, RoHS, and UN38.3 certifications. Marine versions add DNV-GL, while medical applications require IEC 62133. Always verify certificate authenticity via QR codes.

What safety certifications are required?
Essential certs include UL 2054 (safety), IEC 62133 (performance), and MSDS compliance. Industrial models need ATEX for hazardous environments. Chinese factories must show CNAS lab reports.

What safety features do 12V 18Ah lithium batteries include?
Standard protections feature overcurrent cutoff, thermal sensors, and cell balancing. Premium models add waterproof casings (IP67) and impact-resistant designs for harsh environments.

Applications & Compatibility

What solar systems suit a 12V 18Ah lithium battery?
Ideal for small solar setups (100-200W). Powers LED lighting, ventilation fans, and small appliances for 8-12 hours. Perfect for RV auxiliary or off-grid monitoring systems.

Which electric vehicles are compatible?
Fits most e-bike conversions, mobility scooters, and golf cart accessories. Limited to 500W motors due to capacity. Not suitable for main EV traction batteries.

What are typical applications for industrial 12V 18Ah lithium batteries?
Common uses include emergency lighting, security systems, and medical carts. Industrial versions feature extended temp range (-30°C to 70°C) for outdoor equipment.

Manufacturing & Quality

How do China suppliers ensure lithium-ion battery quality control?
Tier-1 factories implement automated production, 100% capacity testing, and X-ray inspection. Batch samples undergo destructive testing (nail penetration, crush tests) for safety verification.

What are the production standards for industrial-grade 12V 18Ah batteries?
Industrial standards require mil-spec components, vibration testing, and IP65+ rating. Cells must pass 1000-cycle pre-testing with <3% capacity variance between units.

Why choose Chinese manufacturers for industrial lithium batteries?
China offers 40-60% cost savings, flexible customization, and rapid prototyping (2-3 weeks). Leading factories maintain IATF 16949 for automotive-grade quality.

Comparisons & Customization

How does 12V 18Ah lithium compare to lead-acid batteries?
Lithium provides 3x lifespan, 50% weight reduction, and 5x faster charging. Unlike lead-acid, it maintains stable voltage under load and requires zero maintenance.
