Testing equip. w/ just a battery.

Post by Blad09 »

Any reason(s) not to use a 12v batt. on its own or perhaps with a charger connected to it, for testing headunit/amp? Thought I read not to, cuz its not regulated well enough or somethin along those lines. just wanna try out h/u pre outs to amp to make sure all is working. Thanks!

you would even be fine with out the charger if you didn't crank it up or need it on for 5-6 hrs and its a good battery. With a charger you might get a 60 hz hum depending on how cheap the charger/radio is.

Won't be crankin it, and wont be for too long so that's pretty much what I wanted to hear. Thanks ttocs. I guess its not much different then running ur stereo in vehicle on acc (without charger) is it?

The lone battery will provide pure DC... it doesn't get any better than that! Hook up a multimeter and keep track of the voltage over time. You may be surprised just how long you can run a system, even with amps, at descent volume before you run into any significant voltage drop.

no the cap would put a larger load on the battery I would think in this case.

I would see no problem playing it off the battery alone for a few hours at a moderate volume on a couple of speakers if the battery isn't too bad.
