Thanks Bill but I am talking about the NAVNET 2 chart plotter not the GPS. Maybe it is the same battery….

The information I have is that the battery for the GP80, 90, & 150 is Furuno 001-428-240-00 which replaces 000-144-941. All I remember was it was easily found, finding the battery was much harder. I had to get it from a Furuno dealer who installed it for the price of the battery which was 80 €.😀😀 The Furuno price for this battery is 30 €.

Although my Feruno Navnet does not come up with the internal battery warning I want to change it. I suspect it is at least 8 years old and maybe original from 2006.

I would rather not ship the unit to a Feruno dealer, firstly they will charge an arm and a leg no doubt, plus all the shipping costs, but also as a matter of principal. I feel it is something one should be able to do oneself if at all possible. 

I guess it is soldered in place probably on little legs directly onto a PC board, but I have no idea where it is located exactly and what is involved. Has anyone else done this DIY route?

If so would be interested to have a few pointers..

Kind regards
