Keeping car battery from not going dead?

[Spray]

I work several hours a day from my parked car. I like being able to charge camera/laptops etc from my car when it's parked. I use a power inverter from the adaptor.

Is there any kind of device I can purchase so it'll cut power off If i'm getting close to running the battery to the point where it wont start?

Kind of an odd request, but thanks.

Why don't you just get one of those portable battery booster packs that you can use to jumpstart the car?

I have one of those actually, just dont want to have to get out and want to be able to move fast

I have a Motomaster one I picked up a few years ago from CT, which has connectors that stay hooked up to the battery. It takes about 10 seconds to connect it and get it going.

Prior to getting that, I had a little solar panel that I used to get a little extra juice in my car during the winter, which was also purchased at CT.

There's a thing on their site called the Eliminator Intelligent Battery Guard, which sounds like what you are specifically looking for, but the reviews are not good.

Get a booster pack(a big one) with a cigarette lighter socket in it and plug your inverter in there. Now if you run the pack dead it's no big deal. Just charge it from your cars lighter socket, while it's running of course! Or charge the pack at home.

Check the manual for your power inverter. Many units have low battery cut-off/alarms built-in.

That being said, standard car batteries don't like being discharged more than 5% at a time, otherwise they permanently lose capacity. You might want to look into a deep discharge car battery, depending on the capacity that you need.
