If you see nothing then you need to buy a star bit or torque bit. I believe it's a t 25 but I'm not 100% on that.

Take out all the screws on both sides. You should be able to pull apart the plastics enough to see the Battery and change it out

You will need a flat head screwdriver to remove the 2 screws holding the Batter

Then unplug the wires

Re install in the reverse order ;-)

Michael, you write 'take out screws on both sides' - Bothe sides of what? Console? Cowling? Where is the battery located? Thanks.

Hi, were you able to visit the site I sent?

Models C7i Only Remove the BATTERY DOOR located on the back of the DISPLAY CONSOLE (#4). Locate the supplied 9-VOLT BATTERY (#10) and connect it to the battery lead. Place the BATTERY into the DISPLAY CONSOLE and replace the BATTERY DOOR.

We have a C9i. I did see link to manual showing schematics. Refers to battery in console for C7i only... So still don't know whether C9i has battery and if so whether it is in console or down under cowling.
