SMF 95E41R
THUNDERMAX
As an ISO/TS16949-certified manufacturer, THUNDERMAX produces the CMF 95E41R, a 12V 100Ah semi-maintenance (SMF) battery built to JIS D 5302 standards. Its lead-calcium alloy grid and 700 CCA minimum rating deliver consistent cranking power for commercial fleets and mid-sized SUVs operating in temperate climates. The semi-maintenance design allows periodic electrolyte level checks, reducing long-term operational costs compared with conventional flooded batteries. Factory-direct pricing benefits wholesale distributors and fleet operators. OEM customization and bulk orders are welcome. Contact us for a detailed quotation based on your volume requirements.

The CMF 95E41R uses a lead-calcium alloy grid that reduces water loss during charging and minimizes self-discharge during storage. Compared with conventional lead-antimony grids, the lead-calcium formulation lowers electrolyte consumption, extending the interval between top-ups. This grid material also resists corrosion better under cyclic charging conditions, contributing to a longer service life in daily fleet operations.
Manufactured to Japanese Industrial Standard D 5302, this battery undergoes standardized testing for cranking performance, vibration resistance, and thermal stability. JIS compliance ensures dimensional and terminal compatibility with Japanese-brand vehicles and many global models that follow JIS battery specifications. The 700 CCA minimum rating supports reliable engine starting in ambient temperatures down to approximately -10°C, making it suitable for temperate climate regions.
The SMF design features removable vent caps that permit periodic inspection of electrolyte levels and topping-up with distilled water when needed. This design gives fleet maintenance teams direct control over battery health, particularly in high-temperature environments where water evaporation accelerates. Unlike fully sealed VRLA batteries, the semi-maintenance format allows electrolyte correction, which can extend usable life in demanding operating conditions.
The battery housing is constructed from reinforced polypropylene, selected for its impact resistance and ability to withstand the vibrations encountered on commercial delivery routes and uneven road surfaces. The casing material also provides thermal stability across the battery's operating temperature range. Integrated carry handles facilitate installation and replacement in fleet maintenance bays.
The CMF 95E41R is suited for commercial fleets including delivery vans, light trucks, and rental vehicles that require dependable starting power with manageable maintenance overhead. It also serves mid-sized SUVs and pickup trucks from Japanese and Korean manufacturers whose battery trays follow JIS dimensions. Aftermarket replacement is a primary use case: auto repair shops and fleet maintenance centers value the JIS-compliant footprint and accessible vent caps for routine servicing. The battery performs best in temperate climate zones such as East Asia, coastal Europe, and parts of North America where extreme cold or sustained high heat is uncommon. For bulk procurement, fleet managers can request customized packaging and private-label branding.
Every CMF 95E41R battery undergoes in-factory testing including charge acceptance, cranking voltage under load, and leak inspection before shipment. THUNDERMAX manufacturing facilities hold ISO/TS16949 automotive quality certification, and production processes follow documented control plans. For commercial clients, a standard warranty applies against defects in materials and workmanship under normal operating conditions. Warranty claims are handled through the distributor or directly with the manufacturer for bulk accounts. Clients may request batch test reports and certification documentation with their orders.
Each battery is individually packed in reinforced corrugated cartons with corner protectors to prevent transit damage. Bulk orders are palletized and stretch-wrapped for container shipping. As lead-acid batteries are classified as hazardous goods for transport, all shipments comply with UN 2800 packaging and labeling requirements. Batteries are shipped in a charged state and are ready for installation upon delivery. Standard production lead time is 25 to 30 days after deposit confirmation, depending on order volume and customization requirements.
SMF stands for Semi-Maintenance Free. Unlike a fully sealed maintenance-free (MF) battery, the SMF design has removable vent caps that allow periodic electrolyte level inspection and distilled water top-ups. This format is preferred by fleet maintenance teams that want direct oversight of battery condition.
For normal temperate-climate operation, inspect electrolyte levels every 3 to 6 months. In sustained high-temperature environments or after heavy-duty use cycles, check more frequently. Top up only with distilled water when levels fall below the plate cover line. Never overfill beyond the maximum indicator.
This battery supports conventional starting and frequent ignition cycles but is not designed for heavy-duty start-stop systems that require deep-cycle tolerance. For vehicles with advanced start-stop functionality, an AGM or enhanced flooded battery (EFB) is recommended. Contact our technical team for model-specific compatibility guidance.
The standard MOQ for the CMF 95E41R is one 20-foot container, which typically accommodates 400 to 500 units depending on packaging configuration. Mixed-model container orders are available for distributors carrying multiple battery sizes. OEM private-label branding requires a separate minimum volume; contact our sales team for a tailored quotation.
