Battery losing power?

Recently I changed my battery to a Northstar 27F. Currently I have a arb dual compressor directly connected to the battery. Could that be the reason I'm losing power overnight?

I understand the battery needs to be topped off, I've never done that since installing, around 3-4 months ago. Could this be a symptom?

Confused as to why it only happens when the truck is sitting for period of time. The volt meter in the cigarette lighter reads 13.8.

Any suggestions welcomed....

 

Is your battery losing so much Voltage the truck will not crank .

How long is it sitting between use.

If your compressor is hooked direct with a pressure switch and your losing air pressure the compressor running to maintain pressure could well be your problem.

If it cycles every few Hours for a few days I am guessing the truck is parked where no one would hear the compressor running ??

Disconnect the compressor see if that cures your problem .

Then think about some sort of disconnect for when you don`t need air .

 

The battery cranks over but struggles for being such a new battery. Normally happens when it's over night or more.

The compressor has a switch from the cabin. It's always off when not in use and the truck is always on when in use. Was wondering if the compressor could take a small draw from being connected to the battery.


Also, never heard the compressor cycle when the truck is off and switch is not activated. I don't even think it works if the truck is in the off position..

 

It was the way you worded it Directly Connected to the battery.

Since it has a switch it is not connected direct to the battery

Some people do strange things at times.

Time to break out your Multi Meter and see what the voltage is .

If the Voltage reads 13.8 sounds like a problem getting the voltage to the starter just a thought.

Maybe test the battery under load voltage dropping lower then it should
