Replacing battery on Feruno Navnet 2


Nick Newington
 

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

On the same subject, I know the battery is a CR2450 lithium 3 volt but not sure exactly the leg configuration to solder or the part number. I think it is 24mm diameter with three legs to solder but not sure.

Anyone know for sure?

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 €.

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

There is one battery inside the CPU that is easily replaced. It is kept in place with some kind of polyurethane foam. It is model 2032 and inexpensive (less than $2).
Just take off the metal cover and you eventually find it. See pics attached.

Hope this helps

HI Bill

From memory, it is the Furuno MPU-001 Navnet 3D Black Box Processor.
It is located on SB, in a drawer under the first armchair

Thank you Bill and Roque  my Navnet is the 2D not the 3D.
I think I will have to wait until I get to the boat in early Sept and figure it out. I was hoping to buy the correct battery and take it with me…

Hello,
I changed the battery on my Furuno GP 90. It is a lithium 2450. price 2 euro.  But it is difficult to do because the battery is soldered inside the GPS.  Removing the old one with a soldering iron is easy, but soldering a new battery without specific tools is very difficult.  I just fixed it without soldering it.  It's been 3 years and it's holding up.

Hi Nick,

the battery for the MFDBB (Navent 3d Black Box)  is a CR 3032 but you don't have to change it since it has no use

Here the feedback from Furono support:

That is a common button cell battery and is not really used in the Kontron processor. Most remove the battery and put the bios setting not to check for the battery.

I have one in spare but never changed it.
