Hi,
I am new with the 993’s. I have had it now for 2 weeks and have taking round for a few rides. I bought the other day a battery tender to keep the battery charged. After 3 days of charging it I went to start the car today and once turning the ignition I just heard a tickering sound. I was surprised since the battery tender should have fully charged the battery which was very low when I bought the car. Does this mean the battery is completely dead, could it be the alternator?

inwold really appreciate any input,
Thanks
Alex

 

Remove the cables from the battery and charge it overnight, then teconnect it and see if the car starts, if so you hava a parasitic drain.

If the battery is more than five years old replace it regardless of other problems!

 

I bought the other day a battery tender to keep the battery charged.
Some battery tenders are capable of charging a charger/tender rated at 1.5 Amps should charge a good battery overnight to the point that it can start the car.
If the battery is three to five years old and has been subject to deep discharge(s) it may no longer be able to take a charge.

• If the battery is of unknown age or condition I would spend the $120 at Walmart and just replace it.

• Once installed start and drive your car around for 20 minutes,
• Afterward, using a voltmeter, read the voltage across the battery terminals with the engine running it should read 13.5 to 14.2 volts verifying your alternator is working.
• If the replacement battery is a fresh one you can turn the ignition off and it should read 12.6 volts or more.
• After standing overnight is should read no less than 12.4 Volts verifying you do not have a significant parasitic drain.

A basic digital Volt/Ohm meter at Harbor Freight is $7.

Hope this helps,

This looks like a defective battery.
If the battery tests to be OK, you will find a DIY page for finding current thieves in the 964/993 here.

If the battery is 5+ years, I would get a new battery to have a solid base line. I would at least get it out of the car and have it load tested.

 

Thanks guys much appreciated on your quick and useful response!

take care!

 

I presume you checked that the connections were tight and clean?
