Battery life

[Charb]

how long is the battery life of a mazda 3 2010 with out the engine on?

this has alot of deciding factors and can differ on many occasions such as what is your battery charge status at when you parked? what trim level do you have? the higher the trim level the more toys included, do you have any aftermarket accessories, are you plugging in a laptop or any outside accessories. The gte with the push button start will shut off the ignition on its own if it does not see the key inside the car after about 30 minutes. Its not that easy to calculate. what is it that you want to do with the car?

Their are to many deciding factors to judge this your best bet is to carry around a small volt meter and just check status every now and then when you are using it while parked if you are that worried about it

With the 2007 GS, I can get through an entire drive in movie with my stereo on (and a 500watt Amp + Sub) Make sure your lights are off... IT really depends on what you are "using" it for. I did ONCE get through 2 movies (4 hours) but the car started slowly. It all depends on your battery, and what kind of load you are putting on it.

and if you did, a simple jump would bring it back to life... no sure how else to respond, the inquiry has too many varables as McGuyver_3 stated.
