Thats a lot of current draw ? I have a meter to monitor battery use , mount uses about .5A tracking , All up with camera ,mount , focuser and fans every thing going I draw about 3A tops. Even laptop only uses 0.9 after boot up I total 5Ah use after 7hr running the laptop.
AGM will discharged lower than 50% as well . The spec sheet for mine say good for >1400 dischages to 10v , they are designed to go much lower than your normal battery , thats what you are paying the extra for.

So if you use the 40ah/10hr battery for 10 hours @ 2.02amps it will be 50.5 % discharged 
Therefore if you use the battery for an average 5 hours a night 5 hours @ 2.02amps it will be 25.25% discharged
That should only be your Maximum usage ever!  |
