Batteries
The GPSMAP 168 Sounder Portable comes with a D-Cell battery pack. Eight D-Cell Alkaline batter-
ies will provide approximately 20 hours of continuous operation. You have the option of purchasing
a 12-Volt rechargeable Gel Cell battery for the portable case from a third-party vendor. The maximum
size of the Gel Cell should not exceed 4”H x 2.5”W x 6”L. If using a Gel Cell battery, you can
anticipate approximately 40 hours of continuous operation between charges. Cold temperatures will
reduce battery life.
Installing the D-Cell Batteries:
1. Disconnect the Red and Black leads.
2. Install the batteries noting the correct polarity.
3. Reconnect the Red and Black leads and place the battery pack (batteries down) in the provide
location within the case.
Installing a Gel Cell Battery:
Verify that the Gel Cell battery has male spade connectors installed on the positive and negative
leads.
1. Disconnect the Red and Black leads and remove the D-Cell battery pack.
2. Connect the Red and Black Gel Cell leads to the Red and Black wires in the portable case.
3. Place the Gel Cell battery in the same location as the D-Cell battery pack. The Portable Case was
designed to accommodate a 12-Volt Gel Cell battery and hold it securely in place.
