StartAux Overview
Big Brain Battery. No Brainer Decision.
StartAux replaces conventional lead-acid starter and auxiliary batteries with intelligent lithium power engineered to deliver reliable starts and mitigate the risk of costly unexpected failures.
Built to start. Built to last.
Batteries for fleets that can’t afford downtime.
Conventional lead-acid battery sets are a recurring maintenance item. Over the life of a vehicle, fleets often replace those batteries multiple times, paying again for parts, labor and unplanned service.
Battery cost is only part of the equation. An unexpected failure can mean roadside service, a stranded truck, a missed delivery and lost driver time.
StartAux vs Lead Acid Batteries
StartAux is engineered differently. Its lithium chemistry and intelligent battery management help fleets reduce replacements, improve uptime and keep trucks in service.

Fewer batteries. Fewer replacements. Less downtime.
*Actual battery count depends on the vehicle’s system voltage, climate, duty cycle, and accessory or hotel load requirements.

One platform.
Three ways to fit your fleet.
StartAux 12V Group 31
150 Ah, fully usable. 1,800 A peak cranking. About 42 pounds, roughly half the weight of the lead-acid it replaces.
StartAux 12V 8D
300 Ah class capacity for the biggest starting and auxiliary jobs, in the standard 8D footprint.
StartAux 24V 8D
Native 24V power for trucks and equipment moving to 24V electrical architectures.
Smart energy management
StartAux is more than a battery. It is a smart power platform for connected fleets, in a true drop-in size. Every model ships with the same power, protection, intelligence, and connectivity, so the battery your fleet buys today is the one it can see, manage, and update tomorrow.
Powered by LiCore
Battery intelligence built for fleet uptime
LiCore turns every StartAux battery into a connected asset, giving your team remote visibility into battery health, location, performance, and alerts from one fleet dashboard. Every StartAux includes LiCore and the first year of cloud connectivity.
