When the engine shuts off, that’s where real comfort and the next morning’s reliable start begin. CARKU’s CBL24230 starting battery, paired with a dedicated parking air conditioner and a pure sine wave inverter, gives heavy-duty truck drivers a complete onboard power solution — built for rest stops, not just road stops.
What CBL24230 Battery System Does For You
•Power Parking A/C — Run cab air conditioning all night long, without idling the engine.
•Run Onboard Appliances — Use the built-in inverter to safely power laptops, mini-fridges, cooking appliances, and other onboard electronics.
•Start Your Truck Anytime — Crank the engine with confidence the next morning, even after a full night of A/C use.
Reduce Battery System Weight — A lithium pack that weighs up to 60% less than an equivalent lead-acid setup
Long Parking A/C Runtime
With 230Ah of capacity (5.9kWh), the CBL24230 can power a parking air conditioner for about 12 hours on a single full charge — enough to get a driver through a full rest period and still depart with a fully charged battery for a reliable next start.
Reliable in Any Climate
Extreme cold is no obstacle: the CBL24230 supports engine starts down to -40°C / -40°F, backed by a 2500A cranking current — even after the battery has spent the night running the A/C.
Built to Last
Backed by a 5-year, replacement-only warranty (no repairs needed), the CBL24230 is engineered for the demands of daily heavy-duty use.

Smart & Connected
Monitor charge level, voltage, and battery health from a smartphone app over Bluetooth. GPRS-equipped versions add remote positioning, remote control, and early-warning alarms for battery faults — so fleet managers and owner-operators always know the status of their power system.
Completing the System
The CBL24230 is designed to work alongside two purpose-built companion products:
DC Parking Air Conditioner
•Dual-stage compressor with full DC frequency conversion and brushless DC fans for quiet, efficient operation.
•3,500W effective cooling capacity — about 60% more than a traditional 2,200W parking A/C unit.
•Rapid cooling: drops cabin temperature by more than 15°C in 10 minutes, even from a 52°C ambient start.
•Available in split-mount and rooftop configurations, with noise levels as low as 36dB.
In-Car Inverter
•Pure sine wave output up to 2,200W (24V) — safe for sensitive electronics and most charging devices.
•Real-time display shows input/output voltage and power status at a glance.
•Ideal for long-distance truck travel, onboard appliances, and home-office power on the road.
Large-Capacity Power
Longer Runtime for Every Stop.
To meet growing demand for longer off-grid power, CARKU has introduced two new large-capacity lithium batteries — the 280Ah and 7.7kWh. Both are built on the same proven lithium iron phosphate (LiFePO4) platform, simply scaled up to give drivers even more runtime between charges.
Extended Runtime
On a full overnight charge, the truck starting battery can power a parking air conditioner for about 16 hours, while the other starting battery model extends that to roughly 18 hours — enough for a full rest period without watching the charge level.
Built on Quality You Can Trust
As demand for heavy-duty lithium batteries has grown, quality across the market varies widely. CARKU batteries go through a multi-step process before they ever reach a customer: individual cell screening, module-level testing, full-unit safety inspection, and high- and low-temperature performance testing. Every pack uses Grade-A LiFePO4 cells with accurately rated capacity — what’s on the label is what’s in the battery.
Designed for Cold Climates
A built-in smart heating function keeps the battery performing reliably even in sub-zero conditions, so drivers in colder regions can count on a confident start every time.
Backed by Experience
CARKU has spent 14 years focused on battery technology, with an experienced in-house R&D team and manufacturing facilities both domestically and internationally — giving drivers and fleets around the world consistent quality and support.
FAQs
How long can the truck starting battery power a parking air conditioner?
On a full charge, the Carku truck starting battery provides about 16 hours of parking A/C runtime about 18 hours, depending on ambient temperature and A/C settings.
What makes these batteries different from a standard lead-acid battery?
They use Grade-A lithium iron phosphate (LiFePO4) cells, which are significantly lighter, last far more charge cycles, and hold their charge much longer than lead-acid — with no regular maintenance required.
Can the batteries start the truck reliably in cold weather?
Yes. A built-in smart heating function maintains reliable starting performance even in sub-zero temperatures.
How is battery quality and safety verified?
Every battery undergoes individual cell screening, module testing, full safety inspection, and high/low-temperature performance testing before it leaves the factory.
What warranty comes with the battery?
CARKU batteries are backed by a 5-year, replacement-only warranty policy — no repairs needed.
