FAQ'S AND SUPPORT

While traditional lead-acid and AGM truck batteries typically last 3 to 5 years, a high-quality LiFePO4 truck starting battery can last 8 to 10 years or more under proper charging conditions. Its longer lifespan comes from a higher cycle life, better resistance to deep discharge, and reduced sulfation compared to lead-acid batteries.

For truck starting battery applications, Grade-A LiFePO₄ batteries offer higher safety, while lower-grade B or C cells carry a greater risk of failure.

Truck starting batteries using LiFePO4 technology can last over 3,000 charge-discharge cycles, providing significantly longer service life than conventional lead-acid batteries. With proper maintenance, they can reliably power your truck for over ten years.

Carku heavy truck starting batteries support vehicle jump starting and parking air conditioning operation. Built with low-temperature LiFePO₄ cells, they deliver reliable performance in cold climates, offer over 3,000 charge cycles (up to 10 years of service life), and feature multi-layer safety protection. The battery also supports forced one-button start, GPS positioning, mobile app monitoring, and comes with a warranty included.

Carku heavy truck starting batteries feature a true 24V design for easy installation, certified safety (CE, FCC, RoHS, UN38.3), long service life of up to 10 years with a warranty included, reliable operation from –40°C to 60°C, smart power reserve to ensure engine starting, high-capacity energy for parking air conditioning, and mobile app support for real-time monitoring and control.

Yes. The CARKU heavy truck starting battery is built with special-grade low-temperature battery cells and an original BMS control system. It provides multi-layer protection against extreme cold, overheating, overcharging, short circuits, puncture, and impact, ensuring stable and safe operation in demanding trucking environments.

Based on our tests, the CARKU heavy truck starting battery can power a parking air conditioner for:

230 Ah battery: over 12 hours
206 Ah battery: over 10 hours
150 Ah battery: over 8 hours

Actual usage may vary depending on the air conditioner model. Users can monitor remaining battery power in real time via the mobile app.

Yes. The CARKU heavy truck starting battery features intelligent low-power protection to ensure safe vehicle starting. When the battery drops to about 15%, the parking air conditioner stops drawing power, and at around 10%, the battery cuts power to the entire vehicle. Users can activate the forced start button to start the engine and recharge the battery.

The charging time depends on the battery capacity and the vehicle’s alternator output. While driving, the CARKU heavy truck starting battery can be fully charged in approximately:

• 230 Ah: 3–4 hours
• 206 Ah: 3 hours
• 150 Ah: 2 hours

CARKU heavy truck starting battery uses Class A lithium iron phosphate cells(LiFePO4), which are inherently safer. Combined with our safe and intelligent protection board technology, it will not catch fire or explode, so you can rest assured.

The CB11 starting battery is designed for commercial trucks and uses LiFePO4 cells, while the CB08N is intended for passenger cars and uses sodium-ion (Na⁺) cells. In short, CB11 is optimized for heavy-duty truck applications, and CB08N is optimized for everyday passenger vehicle use.
