It’s easy to install. The ESM fits into a conventional
battery box. A qualified technician can install the module
in about an hour.†
It’s low maintenance. The ESM is built around safe,
dependable ultracapacitors that require little maintenance.
Just install it and forget it.

It pays for itself. The ESM virtually eliminates the cost
and downtime of jump-starts associated with discharged
or failed batteries.
It’s ultra-reliable. The ESM delivers power for hundreds
of thousands of starts,* ensuring trouble-free starts and
on-schedule deliveries.
It enables compliance. With the ESM installed,
compliance with anti-idling laws is enhanced. Drivers
can reliably start after a night of running sleeper loads.

Effectively eliminate costly
jump-starts, late loads or
Monday morning scramble with
Maxwell’s Engine Start Module.
Dependable performance
and all-temperature starts.
Every route. Every time.
To decrease jump-starts and costly service calls,
fleet managers and owner operators across North
America are installing our revolutionary Engine Start
Module (ESM). It’s not a battery. It’s better. It uses our
proven, power-dense ultracapacitors to reliably crank
diesel engines for a successful start. Consistent starting
means less downtime, fewer jump-starts and lower operating
costs. Start strong. Start today. Start with Maxwell.

Quick-burst power to crank
Rugged, lightweight and low maintenance, the ESM delivers the
quick-burst power big diesel engines need to crank, providing
consistent, reliable performance for hundreds of thousands of starts.
Batteries alone won’t cut it*
Despite some advances, lead-acid batteries today work like they
did fifty years ago. Which means that over time, in extreme conditions,
they can degrade, falter and fail, stranding drivers and putting their
loads at risk.
The ESM takes over all engine cranking–leaving batteries free to
power cab loads, lift-gates, lights and radios. When the key turns,
the engine cranks, even after a night of running sleeper loads on
battery power.
How it works
Instead of a chemical reaction, ultracapacitors use an electrostatic
field to store and deliver power. They charge and discharge rapidly,
supplying a burst of power to crank the engine. Reliable starts
in extreme temperatures, from -40°F to 149°F. Just what drivers
count on.
Ride with the leader
Maxwell is the world leader in ultracapacitor design, delivery and
support. With our ESM, drivers get where they’re going, when
they need to get there–without being blindsided by old or run
down batteries.
