CMF 54017
THUNDERMAX
The CMF 54017 is a 12V 40Ah maintenance-free automotive battery engineered with calcium-calcium grid technology. Manufactured by JUJIANG GROUP in a facility certified to ISO9001 quality management standards, this starting battery is supplied to distributors, repair chains, and fleet operators in more than 60 countries. The calcium-calcium construction reduces gassing and water consumption, which means end users do not need to top up electrolyte during the battery's service life. The sealed casing is designed to contain electrolyte under normal engine-bay mounting conditions, lowering the risk of leakage during transport and installation. Each production batch is traceable through the factory's quality management system, and the battery is available with private-label branding for commercial buyers who require custom artwork and packaging.

Both the positive and negative grids are cast from a lead-calcium alloy. Compared with conventional lead-antimony grids, the calcium-calcium formulation reduces electrolysis and water loss during charging, which is the technical basis for the maintenance-free operating mode. The grid design also supports consistent current delivery during engine cranking and helps extend cycle life under normal passenger-vehicle driving patterns.
The polypropylene case and cover are heat-sealed to contain electrolyte under the manufacturer's specified mounting orientation. The cover incorporates a flame-arresting vent that allows controlled gas release while limiting the ingress of external sparks. This construction reduces the risk of acid leakage during handling, transport, and installation, which is relevant for distributors who ship mixed-container loads.
The calcium-calcium grid chemistry lowers standby self-discharge relative to antimony-grid batteries. This helps units retain an acceptable state of charge during warehouse storage, transit, and seasonal vehicle downtime, reducing the need for recharging before sale or installation.
The CMF 54017 is specified as a cold-cranking starting battery with a discharge temperature range of -15°C to 40°C. It is intended for sedan and compact passenger vehicles whose original equipment requires a 12V 40Ah starting battery. The 206 x 174 x 189 mm footprint corresponds to common DIN-standard group sizes used in European and Asian passenger vehicles.
The CMF 54017 is suited to sedan and compact passenger vehicle replacement programs, workshop inventory for repair garages, and scheduled fleet maintenance contracts. It is also appropriate for distributors building private-label product lines and for exporters assembling mixed-container shipments. Commercial buyers should verify the vehicle's original battery group size, terminal orientation, and CCA requirement before specifying this model.
JUJIANG GROUP operates a battery manufacturing facility with more than 20 years of production history. The manufacturing process includes grid casting, pasting, curing, assembly, formation charging, and end-of-line testing. Each finished battery undergoes a charge and voltage check before packing, and production batches are sampled for capacity and cranking verification in accordance with the factory's ISO9001 procedures.
The production management system is certified to ISO9001 (quality), ISO14001 (environmental), and IATF16949 (automotive quality). The product also holds SABER certification, which is required for entry into Saudi Arabia and other Gulf Cooperation Council markets. Commercial buyers should confirm any additional market-specific certification requirements with their import authority.
JUJIANG GROUP offers OEM private-label services, including custom label artwork and carton printing, for distributors and commercial buyers. The company supports mixed-container loading across battery models and provides standard export documentation. Volume pricing, minimum order quantities, and production lead times are available on request from the export sales team.
Yes. Under the manufacturer's specified operating conditions, the calcium-calcium grid design reduces water consumption to the extent that electrolyte top-ups are not required during the service life.
The manufacturer specifies discharge from -15°C to 40°C, charging from 0°C to 40°C, and storage from -15°C to 40°C.
Yes. JUJIANG GROUP provides OEM private-label services for distributors and commercial buyers, including custom label artwork and packaging design.
The production system is certified to ISO9001, ISO14001, and IATF16949, and the product holds SABER certification for Gulf-market access.
The 206 x 174 x 189 mm dimensions correspond to common DIN-standard group sizes used in sedan and compact passenger vehicles. Buyers should verify the original equipment group size before ordering.
