So after my battery packed, I attempted to replace it but all the batteries keep running down after 72hours or so. 2 rewire technician dad the alternator is working well. Pls what else could b the problem? Somebody talking about kick starter, bla bla bla...

Pls help

The only suspect is the alternator.

Is the battery you replaced it with a new one ?

Are you sure the battery capacity fits the car ?

If U are sure Ur alternator is working and d batteries you have been changing are good,then check for a parasitic drain for eg a coin stuck in d cigarette lighter socket.
Also check carefully for any light,appliance that is on.

Go scan the car, the codes will tell you more on whats draining your car battery

this your comment is funny, I doubt if a scan will tell him what's draining his car.

@op, tell us the make of your vehicle and year so technicians who have dealt with something similar can guide you as appropriate.

There are ways of confirming if the alternator is working by a qualified rewire, then has any recent electrical work been done on the car prior to Changing the first battery?

It's a camry 2000 4 cylinder. . This last battery is a new one. Yes alternator was worked on about 4 months ago but it's not showing any sign of malfunction. The alternator light is not on. Can the kick be responsible, I often need to turn on the ignition twice, these days....

If your alternator has been worked upon. Kindly go replace it

Bro I have same problem with my 2001 Mazda protege.
I have to remove the battery terminal heads when I pa k the car cuz it'll drain it in 48hrs or less.
The alternator is working perfectly as it's been tested by 3 different rewires.

it's called a parasitic drain

u need a professional auto electrician to detect the problem

Something is draining your battery in the car, you need to trace the culprit eg
Is your fan connected directly
Is the after market radio wiring connection done well
Is any after market lamps just installed etc

Yes, my own fan is connected directly but I am not sure it's D cause. I have friends whose car are connected directly but their batteries do not run down...

What works for Peter may not work for Paul. You need to revert back to default

Thanks sir, will be taking the car for a thorough checkup this weekend.

After all, it was a he alternator. I changed it and everything was OK. Really, the alternator may not be charging well without it showing on the dashboard. The rewire said it is called low charging.

So do you believe that putting that so called "diode" means next to nothing

Still check the car for parasitic drain .
