Product Description
Changing the battery on the Celestron NexStar Evolution GoTo mount:

To replace the battery on the NexStar Evolution mount, both housing covers must be removed.

The orange ring on the RA axis is loosened and removed using three small Allen screws.

The eyepiece tray is attached to the base plate with three studs that can be lifted off. There are four screws underneath. Once all six screws are loosened, you can lift off the lid and frame. You will now see the circuit board to which the battery is connected. The cable tie must be removed.

On the DEC axis, there are four screws at the front and two at the back that must be loosened. Here, too, the orange ring on the DEC axis must be removed. The LED cables are long enough to place the lid on the table next to the mount. These cables do not need to be unplugged.

The battery is held in place with a bracket that is secured with a screw at the top and bottom. The cable guides are also secured there. A temperature sensor is attached to the battery with adhesive tape. This must be put back on after replacing the battery.

The battery can now be unplugged from the circuit board and replaced with the new one.

This also opens the mount if you want to adjust the bearing play.
