I am not real excited to spend 300 for a new optima red top. What other options do I have and does it need to be AGM?

This one was purchased in 2008. I cooked the first one from 2007 when I shorted the terminals. Optima replaced it for free.

Whenever I put a flat washer on plastic, I install it burr side up. I do the opposite for metal to minimize lateral slippage. And it's burr side down with a lock washer. The flat(s) on the lock washer go burr side down too.

Whatever...

Ok ordered a 925 we will see


My Odyssey 925 lasted only two years before it died. I'm back with the larger Odyssey 96R as my last one was 10 years old and going strong when I sold that car. I'd keep the 925 on a trickle charger at all times. If you are putting this in the stock location you will need a "frame" to put it in. You may also need the terminal posts. You can have mine if you want them. PM me with your address and I'll send it to you gratis.

Reconsider the Odyssey 680. Less $, smaller and lighter. I’ve used it for 3+ w/out issues.

Technically we don't need a group 42 battery anymore, as capacity has improved over the decades.

Battery sizes also follow similar dimensions, so there are shorter and/or smaller width options.

Lately the 914 gets whatever battery I have in a non running car at the time. My next 914 specific battery will likely be a pc680 or 925.
I've had good results with the Walmart Maxx in the dailies, and the price is cheaper than the auto stores by a bunch.

I put my car on a diet a year ago went with Odyssey PC680 battery, have a hi-torq starter and starting relay. Has been fine to start the 3.2 six. PC925 not a bad idea though incase you need a little extra umph plus your in a little colder climate, not sure do AGM's get as effected as the normal lead acid batteries in cold weather?

So the mount is $150. How much is the battery? $250? What a deal.

How do you attach conventional battery wiring to the thing? Those terminals load from the top & not from the side. I guess it's time for new wiring too. That'll run another 10,000 pesos in parts & labor, especially these days.

Those are cool little mounts.
I'd get the "remote cut off switch model".
So much easier to just pull a knob!

The little baby battery looks neat.
900amps for 5 seconds is STOMPING for something that size.
It's really affordable too! (For AGM technology).

Hope it lasts better than the old style Optimas...

Thanks for the Links Flaca!

And, regardless of windforfun's comments, that stuff is NOT priced badly.
@mb911 what do you think you would charge for a battery mount like that?
I'm betting it's more than 160...
No way I'd try to build that for less.

IMO there are two critical battery rules for 914s.

1. No matter brand or size, the battery must be sealed, especially if it mounts in the stick location. No more 914s need to die from leaking battery acid.

2. Unless you drive your 914 at least 2 or 3 times a week, you need to leave the battery on a charger. Do this religiously, and your battery will last far longer than the stated life.

The fewer the parts the better from a reliability point of view. This is especially the case if the battery gets wet. Besides, the location of a heavy battery helps to balance the load of the driver. Pick your poison. BTW, my Optima rig only gets connected to a tender in the winter time & even if I forget to do this, the car starts up flawlessly. This battery is a "Die Hard" like Sears used to sell. BTDT with the VWs.

@mb911

IIRC I got it on eBay. Pictures below. It fits perfectly into the stock battery tray but you cannot use the stock battery hold down. However it is such a tight fit that the battery can't move, unless you roll the car. If you know anyone with metal fabrication skills they probably could easily modify this to fit the stock hold down (IMG:style_emoticons/default/biggrin.gif)

What you have side mount wiring? Installing this battery is pretty easy to me. I can fabricate whatever is needed. Ps my car stays on a tender all the time with the power to the car shut off as well
