Q: How do I replace the battery in bluebuddy?

A: bluebuddy contains a 1000mA/h Lithium battery that should last for few years (for an average recreational diver). Additionally, bluebuddy comes with a 1 year warranty that includes the battery too. If the battery dies within the warranty period we will replace it at no cost.

After the 1 year period you can either send the device back for a Manufacturer battery service or you can purchase the bluebuddy battery kit - DIY and replace the battery yourself.

Here are the instructions on how to replace the bluebuddy battery yourself.

Before starting make sure bluebuddy and the work area are clean and dry.

First, use a flat head screwdriver to remove the 2 screws in the back.....

... then, using the same screwdriver, lift a little bit the top part of the housing ......

Image


Now, use your hands to remove the top shell.

Image


Once you have removed the top shell, use the screwdriver to lift the board a bit in one corner, and then remove the board from the bottom shell.

Image


Make sure you do not loose the plastic washer located over the pressure sensor!

Remove the 2 screws from the top shell ......

Image


..... and remove the 2 remaining old o-rings.

Image


Now use a soldering iron to remove the old battery from the board.
Make sure that you use an isolated soldering iron.

Image


Once you are done you can dispose of the old battery, screws and o-rings. Please make sure you do so according to local regulations.

Now, prep the new battery.....

... and mount it on the board

Image


Assemble the new four small o-rings on the new screws that were included in the kit ....

Image


... assemble the new large o-ring on the top shell ....

Image


... and assemble the new pressure sensor o-ring on the pressure sensor ....
Make sure to mount the o-ring on top of the plastic washer located over the pressure sensor!

Image


Insert the 2 female screws in the retaining holes of the top shell.....

Image


.... and apply a tiny bit of medium threadlocker ....

Image

Image


Now, re-position the board inside the top shell ...

Image


.... position the bottom shell on top of the top shell ... and press down.

Image


Insert the 2 male screws and, while pushing down on the female screw, screw them one at time.
We recommend you use a torque of about 0.3 Nm.

Image


Please make sure you wait 24 hours before using the bluebuddy as the threadlocker needs some time to cure!
