CMF 54519 DIN45 Battery Technical Specifications

The table below lists the key electrical and physical parameters of the DIN45 12V 45Ah SLA battery. All values are measured at 25°C unless otherwise noted.

Note: Specifications may vary slightly between production batches. Contact our sales team for the latest datasheet.

DIN45 Terminal and Physical Dimensions

The DIN45 terminal layout follows the European DIN standard, with tapered post terminals positioned for direct drop-in replacement in vehicles designed for Group 54519 batteries. The compact footprint (241×174×174mm) fits a range of European and Asian engine bays. Verify terminal orientation and hold-down bracket compatibility before placing volume orders.

Key Construction and Performance Features of the 12V 45Ah SLA Battery

Sealed, Maintenance-Free Enclosure

The CMF 54519 uses a fully sealed VRLA (valve-regulated lead-acid) construction that eliminates the need for electrolyte topping-up during normal service life. The sealed design also prevents acid leakage during handling and installation, reducing workplace safety risks for assembly lines and service centres.

Cold Cranking Performance

Rated at 450A (EN), the cold cranking output provides sufficient starting current for petrol and diesel engines in sub-zero conditions. The low internal resistance (≤10 mΩ when fully charged) supports voltage stability during engine cranking.

Vibration and Shock Resistance

Reinforced internal plate fixation and an ABS resin case help the battery withstand mechanical stress from rough road surfaces and frequent vehicle movement. This construction is relevant for light commercial vehicles, off-road equipment, and agricultural machinery operating on unpaved terrain.

Cycle Durability and Deep-Discharge Recovery

Advanced paste formulation and grid alloy composition improve resistance to sulfation during partial state-of-charge operation. The battery supports up to 1,200 cycles at 20% depth of discharge (DoD) and can recover from occasional deep discharges when promptly recharged. These characteristics extend service intervals and reduce total cost of ownership for fleet managers.

12V 45Ah SLA Battery Applications Across Vehicle and Equipment Segments

The CMF 54519 DIN45 battery serves multiple application categories:

Automotive Starting Applications

Compatible with petrol and diesel passenger vehicles, compact cars, motorcycles with electric start systems, and light commercial vans. The DIN45 terminal standard matches European brands including Volkswagen, BMW, Ford, Opel, and PSA Group models, as well as select Asian vehicle platforms.

Light Commercial and Off-Road Equipment

Suitable for forklifts, golf carts, agricultural machinery, and construction-site utility vehicles. The vibration-resistant internal structure and sealed case reduce maintenance requirements in dusty or high-moisture environments.

Backup Power and UPS Systems

Provides 12V DC power for uninterruptible power supply (UPS) units, emergency lighting, telecommunication base stations, and security system backup. The low self-discharge rate (≤3% per month) supports standby readiness over extended storage periods.

Renewable Energy Storage

Integrates with small-scale solar panel and wind turbine installations for off-grid or hybrid power systems. The deep-cycle recovery capability allows the battery to handle the irregular charge-discharge patterns common in renewable energy setups.

Marine and RV Auxiliary Power

Resists corrosion in humid and salt-spray environments when properly enclosed. Functions as a starting or auxiliary battery for recreational vehicles, boats, and caravan power systems.

Certifications and Compliance Standards

The CMF 54519 DIN45 battery holds the following certifications:

• IATF 16949 – Automotive quality management system certification, demonstrating production process control aligned with global automotive industry requirements.
• ISO 9001 – Quality management system standard for consistent manufacturing and service delivery.
• ISO 14001 – Environmental management system certification, confirming structured environmental impact management across production operations.
• ISO 45001 (formerly OHSAS 18001) – Occupational health and safety management standard.

DIN45 Maintenance-Free Battery – Frequently Asked Questions

What vehicles use a DIN45 12V 45Ah battery?

The DIN45 battery fits European vehicles designed for Group 54519 or L2-400 battery sizes, including Volkswagen Golf/Jetta/Passat (select model years), BMW 3 Series (select model years), Ford Focus/Fiesta, and Opel Astra/Corsa platforms. Always verify the battery tray dimensions and terminal orientation against the 241×174×174mm footprint before ordering in volume.

What is the typical service life of this sealed SLA battery?

Under normal operating conditions with proper charging system function, the CMF 54519 battery typically delivers 3–5 years of service in automotive starting applications. Actual service life depends on climate conditions, driving patterns, vehicle electrical load, and charging system health. Fleet operators using battery monitoring systems may achieve longer average life through preventive replacement scheduling.

Does this DIN45 battery require maintenance?

No regular maintenance is required under normal operating conditions. The sealed VRLA design eliminates the need for distilled water addition or electrolyte level checks. Terminal cleanliness and proper hold-down clamp torque remain the only periodic checks recommended during routine vehicle servicing.

What is the minimum order quantity (MOQ) for wholesale procurement?

Standard MOQ varies by order type. For container-load shipments of the CMF 54519 model, the typical minimum is one pallet (approximately 48–60 units depending on packaging configuration). Smaller trial orders may be accommodated at adjusted unit pricing. Contact our export team with your target volume and destination for a detailed quote.

What warranty coverage applies to volume orders?

Warranty terms are negotiated per supply agreement and typically range from 12 to 24 months from the date of shipment, covering manufacturing defects. Warranty claims require batch traceability records and photographic documentation of installation conditions. Extended warranty options are available for orders exceeding defined annual volume thresholds.

Is custom labelling or private branding available?

Yes. OEM private labelling is available for volume orders meeting minimum quantity thresholds. Custom options include brand-printed battery cases, custom label designs, and branded packaging. Production lead times for private-label orders are generally 25–45 days depending on artwork approval timing and order volume.
