Inside an Aurion Calcium

Fully maintenance-free

Strong cold starts

A tough PE separator helps it start reliably in the cold.

Built-in safety filter

A flame-arrestor filter blocks leaks and helps protect against rupture and corrosion.

See the charge at a glance, and fit it easily with the moulded carry handle.

Is Calcium right for you?

Conventional car

No stop-start system? Calcium gives a standard engine everything it needs, reliably and affordably.

Weekend or occasional use

Low self-discharge means it's still ready to go after the car has been parked for a while.

Simple daily commuter

Steady, maintenance-free power for everyday driving with modest electrical loads.

Stop-start driving

Frequent restarts or big power draws need EFB or AGM. Calcium isn't designed for deep cycling.
