Frankfurt – – September 12, 2026 -- CARKU is showcasing a dual-track battery strategy at Automechanika Frankfurt 2026, positioning sodium-ion and lithium starting batteries as replacements for AGM technology across combustion-engine fleets.
CARKU targets cold-climate markets with sodium-ion starting batteries
The company's sodium-ion batteries are engineered for durability and cold-temperature performance, addressing weight, cycle-life and low-temperature limitations that AGM batteries face in Northern Europe. CARKU positions the technology as a next-generation alternative for passenger cars, trucks and motorcycles operating in extreme climates.
Lithium starting batteries add auxiliary power for long-haul trucks
For heavy-duty fleets, CARKU's lithium starting batteries are lighter and higher-capacity, delivering extended auxiliary power during stationary operation without engine idling. The company frames lithium and sodium-ion as complementary rather than competing technologies, with lithium suited to high-power auxiliary demands and sodium-ion built for extreme-climate durability.
Reverse-polarity protection clip anchors CARKU's patented engineering
CARKU's ODM/OEM production is built on in-house technologies covering structural engineering and intelligent protection systems, including a patented reverse-polarity protection alligator clip design. Manufacturing controls span finished-product housing, A-grade cell consistency, structural design and end-of-line testing, aimed at reducing product failure before vehicles reach end users.
852 global patents back CE, FCC, RoHS and UL-certified product lines
CARKU's portfolio includes jump starters, portable power stations and starting batteries, all certified to CE, FCC, RoHS, UL and other international standards. The company is pitching its integrated technology-to-manufacturing model to aftermarket distributors seeking differentiated, factory-tested battery products for evolving fleet and consumer demands.
