Battery longevity

1477 Views 8 Replies 7 Participants Last post by  Spam16v,

My setup is as follows:

Pioneer AVH-P4100DVD
2007 OEM battery
OEM amp
OEM sub
OEM speakers

My battery has not exhibited any signs of weakness and the last time I took it to the dealer for an oil change, they checked the battery and it was good.

My question is this; my new HU can play DVD's and I was wondering approximately how long I can watch a DVD with the car NOT running? I know this is a subjective question, but I was just wondering from a hypothetical point of view based on the power required to run the system.

I'm definitely not an electronics expert, but would adding a capacitor to my system give me additional time?

Advice appreciated!

The only positive way to be 100% sure how long it will last with your specific setup, is to test it.

There is no other way.\\

Sit in your driveway with a charger and power cord at the ready. Turn it all on , then enjoy a movie. When it stops working, you will know exactly how long it will last. No guessing, no math errors, no question, just fact.
