ok guys

i went through a few old batteries before i went out and bought a new one
anyway, my new $100 + battery died about 2 months after initial usage.
i got it checked out by an auto sparky and he says my system is fine. (twice)

I have tried every theory out, but then i realized... maybe it's because of the heat soak that my battery is dying!?
anyone care to comment?

also i don't have that cover for the battery that came standard either
oh it's an s4

thanks!

I would be checking alt output voltage and current draw.

If a battery is dieing within 2 months of new, then your "auto sparky" didn't check the car out or you have been draining the battery playing the stereo with the key off.

Even with no case, the heat of the engine compartment won't kill a battery that quick.

if you get the battery too hot it will usually do things like leak and boil. unless you got a bum battery theres something else wrong

go to walmart, get a cheap battery for 29.99, they warrenty them for a year, and if you bring it back once a year, they start the warrenty over... i love walmart but only there batteries, and car cleaning supplies

In this case that is like putting a band aid on a knife stab.

ok i'm up to theory #50843

i've stopped using the stereo completely once this new battery died

ok the thory is the fuel pump is taking too much current, therefore when i ***** foot around town it's using too much current? the fuel pump makes funny noises when i have driving lights and brakes on and will stop when i take off brakes.

comments? thanks to the help thus far.

if you have a working alternator the fuel pump can almost take as much current as it wants too. what does the voltmeter say when the car it running?

[YMMIJ]

no voltmeter installed (turbo II)

Icemark

you'll need to get a digital multi-meter and check it then

it should be between 13-14.5v, if not then you will go thru batteries

Icemark

Yep, you need at least 1 volt positive (or 13.6 volts) to charge a 12.6 volt automotive battery.

What brand/size/age was that $100 battery?

Also, whats the condition of the battery/ground/alternator cables.

Get a solar battery charger to top off the battery when the vehicle is off.

Bump the idle an extra 50-150 rpm to improve idle charging.

me and a couple of my friends had the same problem, what u do is run a new power wire from the alt to the battery and make sure its a 4 gauge wire. that fixed all are problems. have any other ? pm me

ok guy's i bought an alternator from the US !
and it should be here next week so thanks for the help so far.

sorry that was $100 AUD which is about $75 USD, it was the biggest baddest battery i could find.

i've grounded like crazy and still the problem persists

i should be right after i get the new alternator in, then i can listen to music again ! yay !!!
