CMF 62034
THUNDERMAX
Engineered for industrial clients, the THUNDERMAX CMF 62034 is a 12V 120Ah valve-regulated lead-acid (VRLA) battery built to DIN 120 dimensional standards. Its thick lead plates and reinforced casing provide starting power for large diesel engines in construction, mining, and agricultural equipment. The sealed VRLA design eliminates routine water top-ups, while partial-discharge tolerance supports onboard auxiliary systems such as hydraulic controls and cab electronics. Certified to UN 2800 and CE, this battery ships globally with a 24-month commercial warranty. Production lead time is approximately 30 days after deposit.

The CMF 62034 uses lead plates that are thicker than those in standard automotive starting batteries, increasing the amount of active material available for high-amperage cranking. This design supports reliable starting of large diesel engines found in semi-trucks, dump trucks, and excavators, including after prolonged periods of equipment inactivity. The elevated cold cranking performance is maintained in sub-zero ambient temperatures common at construction sites during winter months.
As a valve-regulated lead-acid battery, the CMF 62034 uses a pressure-relief valve system that recombines oxygen and hydrogen gases generated during charging, significantly reducing electrolyte loss. This sealed construction eliminates the need for periodic water top-ups, a critical advantage for equipment operating in remote locations where scheduled maintenance access is limited. The VRLA format also reduces the risk of acid spillage during equipment tilt or transport.
While primarily a starting battery, the CMF 62034 is engineered to tolerate the partial discharges caused by onboard auxiliary systems including hydraulic controllers, onboard computers, cab lighting, and communication equipment. This partial-discharge tolerance helps maintain battery health in applications with frequent stop-start cycles, where standard starting batteries may experience accelerated wear. For continuous deep-cycle applications beyond auxiliary loads, a dedicated deep-cycle battery is recommended.
Heat-resistant plate formulations and a thermal barrier coating help the CMF 62034 maintain operational efficiency in ambient temperatures up to 60°C. This thermal management design supports consistent performance in desert construction sites, mining operations, and industrial environments with elevated under-hood or engine-compartment temperatures. The reinforced casing provides additional structural integrity under thermal expansion and vibration.
The CMF 62034 is optimized for multiple industrial sectors. In commercial transportation, it serves Class 8 semi-trucks, delivery fleets, and refuse trucks requiring consistent starts for long-haul routes and frequent stop-start operations. In construction and mining, the battery starts excavators, bulldozers, wheel loaders, and portable generators where unplanned downtime directly causes production losses. In agriculture, it powers tractors, combine harvesters, and irrigation pump engines operating in rural locations with limited service access. In emergency services, it supports fire trucks, ambulances, and rescue vehicles where immediate starting capability is operationally critical. For marine auxiliary power on large work vessels, the VRLA sealed construction and vibration resistance offer practical benefits, though clients should verify installation compartment ventilation requirements with our technical team.
THUNDERMAX manufacturing facilities hold ISO/TS16949 automotive quality certification, and the CMF 62034 production line follows documented process control plans covering plate casting, pasting, curing, assembly, charging, and final testing. Each finished battery undergoes load testing, voltage verification, and leak inspection before packaging. The commercial warranty covers 24 months from the date of purchase against defects in materials and workmanship under normal operating conditions. Registered bulk-account products may receive prorated coverage extending to 36 months; contact your sales representative for account-specific terms. Batch test certificates and compliance documentation are available on request for industrial clients.
Each CMF 62034 battery is individually wrapped and secured in reinforced corrugated packaging with internal cushioning to prevent damage during transit. Bulk orders are palletized with corner boards and stretch wrapping for containerized ocean freight. All packaging and labeling comply with UN 2800 regulations for the transport of lead-acid batteries, including hazard class labels and handling instructions. Batteries are shipped fully charged and ready for installation. Standard production lead time is 30 days after deposit receipt, with expedited options available for established clients depending on production scheduling.
Yes. Units can be connected in parallel to increase total capacity or in series to achieve 24V systems common in heavy trucks and construction equipment. When connecting multiple batteries, ensure all units are the identical model (CMF 62034), of the same age, and at equal state of charge before connection. Mismatched batteries in a bank will experience uneven charging and reduced overall lifespan.
The CMF 62034 has a self-discharge rate of approximately 5% per month at 25°C, allowing it to retain a usable charge during moderate storage periods. For equipment that remains idle for more than 3 months, connect a maintenance charger (float charger) to preserve charge capacity and prevent sulfation. Store in a cool, dry location away from direct sunlight.
Yes. The CMF 62034 meets UN 2800 transport requirements for lead-acid batteries and carries CE marking. The manufacturing facility is certified to ISO 9001, ISO 14001, and IATF 16949. Note: the published specification sheet references ISO 18001, which has been superseded by ISO 45001 for occupational health and safety management; updated certification documentation is available on request. SABER certification supports shipments to the Saudi market.
THUNDERMAX offers a 24-month commercial warranty covering defects in materials and workmanship under normal operating conditions. For registered enterprise customers with bulk purchase agreements, prorated coverage may extend to 36 months from the date of purchase. Warranty claims require proof of purchase and a failure analysis report; contact your account manager to initiate a claim. The warranty does not cover damage from improper installation, overcharging, physical impact, or use outside the specified operating parameters.
