how long does the battery last...
so how long does your battery last (on average of course) when watching a movie or playing a game system on your double din unit with your engine off? this is assuming your not blasting the sounds.
i've only ran a dvd in my d3 for about half an hour. also, i've run the radio with the screen off for about 2 hours, lol and had no problems with the car starting. idk, im just scared to watch a whole movie and not have my car be able to start. :nails: also, if the stock battery is not good for this, what battery do you recommend to increase the longevity of being able to watch movies/play games with the engine off? |
We watched a full movie on my friends d3 once. So I at least know its possible but I think it also depends on if the battery is still fresh or if its on it last legs type of thing. Thats what my friend said anyway.

Total discharge time will all depend on the age/strength of your battery. Logically, an '07s will probably last a bit longer than an '05s.

Check the watts that the unit(s) are drawing and divide that by 600 and that should be the hours it should play with a good battery. 600 = 12volts x 50 amphours

i went 3 hours on my yellowtop the other day. this was with my stereo at 3/4 max volume with my avic d2 + 1800 watts
|
get a volt meter if you concerned about it. i have 3, one directly off the battery, one inside of the car on my gauge pillar, and both of my caps in the back have them.
every single gauge reads a different voltage, but that is expceted because of voltage drop, and different loads (especially with the caps) I get a major voltage drop with my music blasting after about 3 mins, so i keep my car runnin. oh... im on a yellow top too... my second one |
yup,if you plan on going LONG periods 3 hours +,then get a yellow top.I say a stock battery should take a good 2 hours at mid volume with enough to start up.

for pinks? hahahaha. you ammuse me scott. you hit harder then i.... but if i re-wire my system.... might be another story. but i wont re-wire it... so you win. haha

re-wire what? we can race for pinks! go ahead and re-wire!! What are you going to re-wire it too?
I want to see what my 1 measly 15" sub can do compared to your 2 12" and 2x amps!!! |
cool thanks for your experience and info. i was afraid my car won't start if i leave it playing for about an hour. my unit itself reads voltage, and my turbo timer reads voltage also.
i know voltage doesn't mean as much as amperage, but what kind of voltage readings should it be over with the car off? in the morning, at the unit, it read 12.8 and slowly dropped to 12.6 over a few minutes. |
12.5+ is optimal. Lowest mine has gone is 10.9. Me and some friends were entertaining the high school parking lot. :P
