left lights on, killed batt. Charge or replace?

[Starter986]

I don't know about the ctek or other trickle charger, but here is my story...

I've had batteries completely drain on more than one occasion. So drained that when I connected my battery charger... it refused to charge because the battery was spent. So...

I would remove the battery... hook up another battery.. start the car... remove that battery (with the car running)... hook up the dead battery... and let it "charge" for about 15 minutes. I'd then shut off the car... hook up the battery charger... and the battery would register just enough juice to allow the charger to do the job. Has worked every single time I've encountered that problem.

You don't have a charger... so after you reinstall your dead battery... go for a long drive. That'll get you back to normal.

Good luck.
