Battery dies fast.

Hi Guys,
My battery is dying once every 2 days or so,
I keep it charging every day,so I have a sure start at work,shopping mall parking etc.
FSR changed recently...battery is new form the dealer
if I get a weary crank,which happens often I just let the X idling for 5 min and it restarts like charm,so I assume the alternator is kind'a charging the battery.
I bought a battery/alternator tester that goes to the cig.lighter and it's showing no alternator LEDs when coming to stop or some equipment is turned on and they come on in about a second,so that shows that the voltage is dropping below 13.4 V or so.
So far I was lucky to start every time I had to go to work,but this problem is getting worse,so any advise is welcome.
Thankx.

put a meter on it and measure the current draw when the vehicle is asleep. disconnect fuses until it is under 50ma.

I'd check the alternator. It might be cutting out when it gets hot.

I am wondering if it could give the right Volts but low Amps?
What do you think?
In that case,I guess,battery would not get a fully charged.

That's why an alternator test loads it down and tests the output amperage.

Hi Weasel!
Thanks for an input.
I am kind of busy to go and just get a simple test,shame on me...
Well,I guess any mechanic shop could check that out,right?

Yep, but not all mechanic shops can track down a parasitic draw... in fact most aren't even equipped to do so.

About that FSR: turn off the car and let it set for half an hour. Go back in and put your head under the dash and listen to see if you can hear the fan blowing at a low level. If so, your FSR is not good.

No need to wait half an hour... the fan should not be blowing at all with the ignition off.
