2000 camry can't start. urgent

[amputation]

Sorry probably this question had been asked b4 but i can't find a solution for my car.

After 3 cold days idle, i start the car. The engine light is on but there is no cranking sound. Only the sound "tak tak tak" like machine gun triger. I changed the alternator which cost me a fortune but the problem still exist.
Please help me!
great thanks

Try charging your battery

When you are in cold temperatures, it makes your battery weaker.

Take the battery out and bring it somewhere so they can test / charge it. Or have someone hook jumper cables to your car for 20 minutes and then try to start your car.

Most car/truck batteries will/should have an open circuit voltage of 12.6 volts. If your battery discharges over a period of time, which can happen with a simple parasitic draw (such as a on board CPU) or possibly leaving a interior light on, this will cause the battery to discharge.

When a battery is fully charged it has a specific gravity of 1260 (this is the measurement of sulfuric acid) this measurement can be checked with a hydrometer, when the battery discharges the sulfuric acid goes through a chemical reaction and becomes more like water and would measure a specific gravity of 1000.

If water freezes at 32 degrees F and you battery was completely discharged, then it is fair to say that your battery froze solid like a ice cube.

Once this happens, the battery is 99% unrecoverable. Your trickel charger would be useless on the battery.

When you replace your battery, you should have your charging system checked out. This can be done at any Auto Parts store or a local Walmart free a charge.

In the future, if you plan to leave the vehicle longer than 4 weeks, you should disconnect the negitive cable from your battery. This will eleminate any paristic draw down.

thanks i will try this right now.

The best way to charge a battery is to put a battery charger at Low Charge at room temperature. So if you have a battery charger, grab your battery .. bring it inside, let it get to room temp. and run the charger on low for 3 or 4 hours.

Just bringing the battery in and letting it get to room temperature may even allow it to heat up enough to give you the proper cranking amps you need to start the car.

After getting your car started, bring it to autozone and have them do a load test on the battery to determine if its good or not too

I don't think they have AutoZone in Canada...yet.

It would be good to have a voltage reader, too...since yer up in the cold area of North America.

You should be able to find one at Walmart Canada or on eBay. The one I'm talking about is the kind has the digital display and plugs into yer cigarette lighter.
