That's why I got one for my '66 Beetle (12 volt conversion) It won't rust out the now repaired battery tray! Also, you don't want to put a super-hyper battery charger on them. They tend to like being charged on the slow side.
I splurged on a red-top a while back when I needed a new one because I had heard how good they were as a battery, but I did not know about the safety features you mentioned!
I just put a red top in my Scirocco, and it starts so much better now... I have seen lots of batteries fail, and nine times out of ten it's a cheap piece of crap like the duralast... The only batteries I have seen hold up in the long run have been Interstate batteries, and Optima's.
Go optima red top, 109@ autozone with a return core (your old battery) They are expensive for a battery, but they are worth it. Ask anybody on vortex about them, they know.
The previous owner of my VR6 killed a red top, by letting the car sit weeks at a time. After doing this for about a year the red top would not hold a charge. After driving it, and parking it overnight the voltage would be high 10's/low 11's....not good for starting a car. A yellow top was used as a replacement. It took the sits fine, because of it's design. Now a few years later I have the car and it still holds high 12's over a few days of not being started.
I went with a Red Top...Optima's 75/25...primarily because it is smaller. It only weighs 31 lbs and is slightly smaller in overall size. It still has 720 cold cranking amps and I do not have 2 tons of stereo equipment to push. If you got 4 years from you stock battery that is GREAT. But everyone I have spoken with said this was the LAST battery they purchased...some going on 7 years now. Although the terminals ARE reversed on this model for our European applications...I have PLENTY of stock cable length to make the connections. I paid $100 for mine at my local Batteries Plus store...
Before anything I'd replace the battery, something like an Optima Yellowtop. I never bothered with caps, the yellowtop put an end to the lights dimming rather quickly.
Louis, the Optima has a reversed polarity pole set up. You will have to extend you cables and now the positive post is very close to the fender wall. Pray that it doesnt slide during a hard turn.
FYI New optimas are the suck. Good luck though.
I just popped the plastic bottom edge off the factory battery and put it on a new replacement one from Autozone for something like $69. Same size and fit and post placement as factory Varta but made by Johnson Controls (I think). I personally would not buy another Optima. In the four-wheeler world, I've heard many complaints of premature failures. I've used red-tops as well as yellow-tops in my Land Rover and had to have them warranteed within 2 years of purchase due to sudden failures.
