I have used a 12v 12Ah battery with my previous scope. A C8+CG5 mount
I got it from here.... www.securitydirect.ie/batteries/yuasa-yu...echargeable-battery/

It worked very well. Powered the scope, an ASI cam and a small netbook for 5 or 6 hours.

Hi Derek
Thanks for the Information regards the Battery. Could you tell me what type of Cable you used to connect the Battery to the Telescope. I'm assuming ill need a Celestron Cable with Crocodile Connectors to use this type of Battery.

Would I need to purchase some sort of AC cable for charging and a different cable to connect to the Telescope 12v Connector ?

At present I have a 7ah Celestron Power Tank but the Battery is flat in it and it has a Cigaratte type Adaptor to plug into the Scope and a separate ac cable that plugs in to the DC in port.
regards
Stephen.

You can replace the batteries in the Powertanks. I changed my Halford Powerpack batteries recently and they work just as good as new. They are a standards size so there are several choices and brands.

Stephen,

Ah yes I made up a socket with 2 crocodile clips and one of those cigar plug extender things (which I got in Aldi or Lidl)
It had 1 cigar plug on one end and 3 sockets on the other end.... I cut the plug off and attached 2 croc-clips.

You will also need a 12v charger for that battery. I already had a car battery charger.

I wonder if the 7AH battery in the power tank is the same size as this one www.securitydirect.ie/batteries/yuasa-yu...echargeable-battery/
Maybe you could replace it.

Derek

I haven't taken a Celestron 7ah Powertank apart before, but Ill have a go as the Power Tank itself is in good condition.
It just dies after 5m so will look into replacing the Battery.
Thanks for the Advice

Once I get it apart I can check the Size. Must look for a Utube Video on taking the 7ah Power Tank apart as looks like I mignt need some extra long screw driver.
thanks

The batteries are a standard size so there should be no trouble sourcing a battery at a fraction of the cost of replacing the entire unit.

Just check the connector type for your current model. I picked up mine from a battery world shop locally

I went to Battery World Shop in BallyBough Dublin and they took the Celestron 7AH Power Tank apart and replaced the Battery for me and fitted an 9AH battery and working perfectly now. Battery world can also do up cables for Larger Batteries so one to remember if your looking for a larger Battery at way below the Cost of a Power Tank
thanks
