At 11.63v it is certainly bu....ed for motoring use, but if you are looking
at powering a single dew heater for an 8" scope, or a couple of small ones for a 4" for example, it would probably last for an imaging or viewing session. I run my HEQ5, 1100D, and a single dew heater for my 8" Newt
with a worn out car battery. It lasts about 7.5-8 hrs, bearing in mind
that the HEQ5 is pretty power hungry.
Nothing to lose, anyway, so give it a go.
