optima or compatible battery how long car off
Hi all,
Just was wondering is someone could give me a estimate time on how long I could run my carputer & amps with my car off with my optima yellow top.Just say a have the volume cranking and pulling about 3000 watts (amps are 3300 watts total) plus the inverter for the carputer.
I know I will not have it at full volume but just was wondering if I was at 3000 watts what time am I looking at?
Are we looking at minutes or 1 hour etc..
Thanks
Michael

Well if you go by my 3000 watt example. 3000 watts into 12v = 250 it would be about 250 amps.

sorry, wattage claims from amp manufacturers are usually all over the place. I wasn't going to assume that the figures were accurate.

10 to 1 this is peak power, NOT RMS, give us RMS specs with listing your car audio system. Peak doesn't mean anything.
Regarding how long...
I had a Stinger SP1700 battery in my car running a US-2000 amplifier (that's 2000watts RMS, NOT PEAK mind you) and I ran it for 4 hours with the car off, at about 90% volume to burn in the speakers (4 12" Eclipse 8700s).
Should give you an idea. However, this was a new battery as well with proper wiring, etc.
Older batteries will vary as well.

And seeing how he's using a deep cycle battery, it'll depend on when the thing was cycled last.

Hi,
yes it is "RMS" I have 2500 "RMS" to the subs 400 rms to the components (100 rms each) plus the carputer.
It is a newer yellow top about 6 month old.
I know the manufactures inflate the ratings but that it what it is "supposed to be) LOL
Thanks
Michael
