The voltage range on lead acid, from full charge to well discharged, is well within the capbility of telescope electronics.

You will find a fully charged 12V battery will be around 13.5V shortly after removal from the charger.
If in use it gets down to 10.8V (1.8V/cell) stop using it and get it on charge in the next few hours. Definitely don't wait days or weeks before recharge.

Good news. Many thanks for your reply, David. I'll give it a try this evening  👍

Best wishes,

Sorry for dragging up an old thread...can you just connect the battery terminals to the scope mount power socket (via appropriate wires) or does it need regulating to 12V?  A fully charged Pb acid is ~14.4V is it not?

We're off camping this weekend so I'd like to take the scope if possible.

Many thanks,

Jason
