I was having a fire the other night out back and accidentally sat on my key fob and set off the panic alarm on my first generation Cadillac CTS. It drained my battery to where the electronics in the car still worked but it wouldn't start. So I put a battery maintainer on it and let it charge to 100% and no dice. Jumped it using another car and it turned right over. I drove it around and noticed some controls got messed up. Came back the next morning and the car was 100% dead. No electronics on in the car and the key gets stuck in the steering column. I called around regarding the messed up controls and they said it was either a bad battery (not supplying enough voltage to all the components) or it just needed reprogramed. So I call around for quotes on a new battery...first place I call quotes me at $196.00 ! I figured that couldn't be right and called around some more. To my surprise, everywhere else I called had them around that price or didn't carry them at all. I found a retailer online that offered a discount if ordering online with in-store pickup, so that's what I went for. I still paid over 100 bucks for this battery. Pop it in and the car starts fine. Controls are back to normal. My question is: why does my car need such an expensive battery? My dad has an Escalade and just got a new battery for about $99, why did mine cost 1.5x that?
