Battery OPTIMA or Duracell

I have a redtop 75/35 and it fits fine. The battery cover doesn't fit over without a little modification though. And you have to slightly trim the top bracket that folds down over the battery..

red top model # 8020-164-35 RT I have one and it fits perfectly in the oem battery box and cover.

Redtop here as well - fits fine and bolts in just fine.

i'm very pleased with the battery's performance. i took the family to the drive in theater and sat through 3 movies listening to the stereo and using the lights. when it was time to start the van, it did so without even the slightest hint of complaint. also, this afternoon my EV gave me a fit and would not fire up at the car wash. i cranked the living bejeesus out of the starter and the battery never once gave a sign of weakening. no jumps were needed. a highly recommended battery alternative!

I put in a Optima yellow top that I got at Costco for about $150. I bought a $5 extension so my wires could reach the terminal. Great sealed dry cell battery!

Its minor but there are 2 different technologies in use...the red battery is designed for cold starting while the yellow was designed to handle added accessories...at least thats what i take from the website...it also says that if you use a red top in a car with enhanced car audio the warranty on the Red Top is void...take that into consideration...

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.

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.

optima=the suck... one year on a yellow top turned into .05 volts under load....

The new optimas are junk, I would get a conventional battery and call it a day. I have had numerous red tops in the past in various vehicles and they last no longer than a regular battery should and I didnt think they were all they were cracked up to be. When it came time after 4 years to replace the battery in my car I just got a conventional interstate and have been happy since
