How to use the Simrad P I Charger
The Simrad PI Charger is an intelligent battery charger for
fast and secure charging of the PI sensors. The charger will
automatically set up the correct charging current depending on
the sensor type and the battery temperature. A “fuel meter”
shows the status of the battery during the charge.

Even though the PI Charger is designed for fast charging of the
PI sensors, it can also charge the PS sensors, but only at normal
charge rate.
