Battery replacement, Any0ne using a Duralast Battery ? Options

[jim_hoyland]

Looking for a Duralast that's suitable for the 914 ?
Which one works/fits in the914 ?

I'd use NOTHING but an AGM in a 914.

Absorbent Glass Mat...

Sealed, cannot leak acid.

Usually 30-50% more expensive than lead acid...

Dura-last would NOT be my first choice.

I like Interstate but that brand may not be available where you are.

I believe this is a Costco choice. Their warranty is unbeatable.

Costco claims you can order an AGM battery, but it looks like they have only a few choices. If you use their "battery finder" search tool there is, at least in this area, no option for a 914. However, our cars use the same battery as many Ford Mustangs so you can search for a battery for a 2006 Ford Mustang and it will give you an Interstate 40R which fits perfectly. An Interstate 96R will also fit perfectly, but Costco in my area does not keep it in stock. I got an Interstate 40R off the shelf at our local Costco for $97. The same battery was $199 at my local auto parts store. The AGM battery I use in my other 914 is the Odyssey 96R, which you can get for around $325-350. My last one was still going strong at 12 years old and went with my previous 914 when I sold it. I got the Interstate battery from Costco because at the time I needed a battery the Odyssey 96R was out of stock at just about every place I looked, and the price for the Interstate battery was a deal. Not a fan of a non-sealed battery in my 914, but I never drive it in the rain and the car is garaged at all times, so probably OK (IMG:style_emoticons/default/confused24.gif). Of course for some people the weight of the battery is a concern. I'd rather have a beefier battery and carry a few extra pounds. The way that I drive my 914 it does not make any difference to have a few more pounds of weight.

I have the same Interstate AGM Group 5 size batteries in both of my 914s. The first one was installed around 3 years ago by an Indy repair shop for around $250 and the second purchased at a local Costco last summer for about $150 plus core charge which was refunded. These look like a conventional wet battery with the same base and were a perfect size fit using the original clamp. I'm pleased with the performance and value.
