FAQ'S AND SUPPORT

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

Motorcycle battery lifespan: Similar to the previous point, this answer discusses the lifespan of motorcycle batteries, offering an indirect comparison to the expected lifespan of jump starters used for motorcycles. It emphasizes the importance of replacement when the battery's performance drops.

The JS-557 jump starter provides a peak current of 1500A, which is sufficient to jumpstart most 12V cars. Typically, jump starting a car requires between 200A and 600A depending on the engine size and battery condition. For detailed specifications, you can contact us to get the JS-557 datasheet.

Lithium cobalt oxide battery: high energy density, high starting current, and larger capacity for the same volume.

Lithium iron phosphate battery: good safety and long cycle life. It can be charged and discharged quickly with large current, has good high temperature performance, no memory effect, and is green and environmentally friendly; however, the capacity of batteries of the same volume is smaller than that of lithium cobalt oxide batteries.

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.

Yes — a 24V LiFePO₄ jump starter is widely considered one of the safest and most reliable lithium-based solutions for starting a 24V vehicle battery system, especially in heavy-duty or RV applications.

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.
