charging help needed

[dean w]

I have just charged my battery up it was showing 10 volts before and now is showing 13.5 is this safe to use on my mount which is a skywatcher eq synscan goto as it says it needs 12 volts

I'd wait for a few opinions (to share the blame if I'm wrong) but I'm pretty sure its fine, if you test a car battery or ciggie lighter adaptor they are always about 13.8v

In fact the bench power supplies are about the same.

all the best

It will probably drop back down a bit but 13.5v is not unusual in a car battery and should not harm your synscan. If you read the Skywatcher manual I think it should say 11-15v range.

yes 11-15 volts is printed in the skywatcher manual

I sometimes use a mains powered 12v transformer but it regularly churns out anything up to 14.2 volts

Good news....

I've been using my HEQ5 and NEQ6 mounts with 15V for the past five years with no issues.

I use a 120W car computer voltage convertor (Maplin) from 12v to 15V - works great!

Thanks for the replys put my mind at ease cheers

Prob just residual charge from charging it will dissipate when left a while...on a car you would test by leaving headlights in a few minutes. ..Davy

not a problem, the mount is rated to 15v and behaves better with the higher voltage.
