Why SkelStart

Batteries are the leading cause of starting failures.

Tap any point to open it up — the short version and the number behind it.

In an emergency, SkelStart's ultracapacitors can get the engine started even with a dead or missing battery — a genuine failsafe, not a battery replacement. In normal operation, the ultracapacitors handle the demanding starting load and the battery only carries low loads once the engine is running.
Batteries are vulnerable in extreme weather — SkelStart's effective operating range makes it a perfect fit for bus, truck, rail and heavy equipment in any climate.
By taking over the demanding starting load, SkelStart increases battery lifetime — fleets have gone from replacing batteries every two years to far longer.
Ultracapacitors can charge and discharge millions of times, offering lifetimes up to 500 times longer than lead-acid batteries.
Delivers fuel savings, faster cranking, and reliable starting without needing to keep engines idling to protect the battery — can replace a battery or be added alongside existing ones.
How It Works

Ultracapacitors, not chemistry.
