A closer look at the battery says it’s a used one from Autozone that was purchased Sept 27, 2017.....last f’g week!

I’ll get a decent replacement during lunch tomorrow. And a tender.

I'd take the battery back to autozone and ask then to fully charge it . I'd suggest getting a 4 to 10 amp battery charger . One that will do "tending" as well as charging .

just watched a 20 minute sales pitch on Frank's EZ battery course add here on Spit/GT6, $47.00, it teaches you to recondition all used and dead batteries back to 100% for big profits.

Was that "USED BATTERY" one of these home business batteries sold to Autozone ?

No idea....I have never bought a used battery and makes me wonder why would one use a used battery.

Like the birds say, "Cheap cheap." And sometimes it works.
All the best,

I got a rebuilt battery when I decided to get my spit going after being parked for two years.

$10.

Lasted about a year with a float charger.

Wellllllll....it's never over till it's over right? The new battery was doing great until this past weekend. Ran the car for a few hours and made several stops. Last stop the car would turn over slowly. Got it home and the battery was reading 11.8 volts with the car off. Jumped it and it read 12.2V. Now I look at the alt. It is not the original generator but it is a Lucas alt...maybe from 15 years ago. It is a 3 prong type. The nuts on the alt are rusty. Also the belt drive seems to be not as taut as it should. I've read the belt should have 3/4" of stretch. I have close to 1.25". I'll adjust the belt and see what it does. If nothing then it will be the alt that needs replacing. Any words of wisdom?

Go for more power. 35 amps is a little thin.

What kind of voltage are you getting with the engine running? How about when younstart turning things on...ligths, fan/blower, radio?

Maybe disconnect radio temporarily, to see if that is not draining the battery.

Take the battery out and fully charge it , put it back in , then put your meter to the battery . Voltage setting , what does it read pre starting , what does it read post starting at 900ish motor pms , then what does it read at 4000 rpms ?
1) Voltage pre start =
2) Voltage post start , 900 ish rpms =
3) Voltage at 4000 rpms =
With those 3 voltages a "picture" can be formed and maybe "read" .

Basically.
With the car runnning.
2 voltage checks.
1 from battery terminal to ground. North of 14v.
2 from the alternator to ground. North of 14v.

If you have 14+ at alternator and less at battery. Condition your wires.
If both are the same 12vdc. Then replace your alternator.
If you have added anything to the system. Radio, sub woofer, fog lights, driving lights. Get a replacement with more amp output.

It's good you have voltage. However current is more important. With out a load check on the alternator, it's just guessing by voltage information.

Your new battery is still new. I wouldn't worry about it. Just charge it.

Welcome to the Forum Pete. Advance Auto will test your alternator for free. Hopefully it's OK, and the belt has just been slipping because it was too loose.

In reply to # 1489865 by Tonyfixit I have fitted a battery disconnect switch to disconnect the power supply if need be.

If you had one fitted it could help solve this problem.

There is a disconnect on the battery from the PO. I never thought the battery would loose charge overnight. I'll get a tester on the way home and start to fiddle with it.

Thanks guys!

PS......this place is friendlier than the Porsche forums smileys with beer

Porsche people love them our spit beats most of the porsches when we run there autocross events. Drives them crazy
