Celestron Evolution battery problem

[BGazing]

By the way, is there a way to power the mount from an external source if the battery goes dead or is near depletion?

It seems you can connect and use an external battery if the scope can be turned on using the internal one. If the scope is totally dead and will not switch on connecting an external power supply makes no difference. I have the dead battery problem. Unfortunately I bought scope used and it has been fine until now. I am hoping I can find out how to replace battery myself so any clues would be appreciated.
