Installing deep cycle battery
Hey,
So I have a 98 C5 and I've been putting money into it and my next stop is a new paint job or something else. I also work for an insurance company (starts with a G) so I know how often people get screwed.
Which brings me to this. I installed a camera system in my car, front and back. The issue is the camera only has about an hour of battery life.
So my solution is to buy a few 12 volt deep cycle batteries and store them in those small cargo areas in the trunk. I am going to use sealed lead acid batteries. My question is should I use a standard ATV battery or can I use a few small 12 volt alarm system batteries.
When I went to micro center someone there told me that if I hooked up a small 12 volt to my car the battery would explode because the alternator puts out 90-120 amps.
Edit: the current circuit the camera is on kills battery power when I turn the car off.

Why don't you just install an automotive relay on the B+ wire feeding your cameras and energize the relay coil with switched power so they're only turned on when the car is running

I would like them to record when the car is parked but not kill the battery.
