At Automechanika Frankfurt 2026, CARKU showcased a range of starting battery products, highlighting its product development across two key technology routes: LiFePO4 and sodium-ion (Na+). As truck power needs extend beyond engine starting, battery systems are increasingly expected to support both high-current starting and sustained onboard power. Traditionally, these two demands have been addressed by different battery types, raising a practical question for truck applications: can one battery reliably handle both?
What can one dual-purpose battery do?
- Engine Starting ▶Delivers high-current power for starting the truck engine.
- Deep-Cycle Power ▶Supports sustained discharge for auxiliary loads during parking.
- Parking A/C Support ▶Works with an inverter to provide power for parking A/C.
- One-Battery Configuration ▶Combines starting and auxiliary power functions in a single battery system.
How Does a Dual-Purpose Battery Support Truck Drivers on the Road?
For truck drivers, battery demands change throughout a transport journey. The battery needs to provide reliable starting power before departure, while also supporting onboard electrical needs when the truck is stopped for loading, rest, or overnight parking. CARKU’s CBL230D-24V LiFePO4 dual-purpose battery is designed to support these different stages with one battery system:
Before Departure ▶Delivers high-current power to start the truck and get the journey underway.
During Loading or Short Stops ▶Supports auxiliary electrical loads without relying solely on the engine running.
During Driver Rest ▶When paired with an inverter, provides power for parking A/C and other onboard equipment while the truck is parked.
Before the Next Journey ▶Continues to provide starting power after extended stops, helping support a reliable restart for the next leg of a transport journey, including refrigerated trucking operations where vehicle readiness is essential.
By combining these two capabilities, the CBL230D-24V is designed around the real operating cycle of transport trucks, supporting both driving and parked-power needs across long-haul and refrigerated transport applications.
