[CA] [CA11] nav 398 battery

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum vrerisi,

The part number for the lithium ion memory battery for the NAV398 was 5ZBAD00089. This battery featured legs which were welded to the battery, permitting it to be soldered to a processor board. Unfortunately, specs for this battery, as well as parts, service, and support for this long ago retired product are no longer available from Raymarine. You may want to consider having Batteries+Bulbs or a similar battery replacement company replace the battery within your NAV398, as it involved soldering.
