I have had good experiences with Optima batteries. The one that I put in Underdog was a little narrower than the stock og battery.

Don’t buy an Optima. They suck these days.
If you want a gel cell batter get an Odessey battery. Stay away from the Red Top.


I've been checking Oyyessey pc680,925, or1200 do you know which one fits best thanks


Concur with VaccaRabite. Though they won't fit as per factory but not difficult to fashion a bracket or chose from an assortment of brackets out there. If you shop around you'll find they are less expensive than Optimas, weigh much less, and last longer. Amazon Prime member? They have the best deal I've seen lately and free shipping with Prime.

BTW I run a 925 in the 911 and moving the 914 to the same.



ill 3rd this statement. Optimas WERE good but that was over 10 years ago. Older ones lasted forever. First on I had came in a used car I picked up, I moved it between multiple cars and it lived for 12 years. Seemed like a good investment so i bought a 2nd (post 2005) and it died in 2 years. Switched to Odysseys, haven't had one go bad on me yet. I have both a 925 and a 680 in 914s both using Rennline mounting kits

Added bonus, they are way easier to get in and out of the car due to the size and weight. Always worried I would bang up the paint getting the optima in and out of the engine bay, pretty sure I could get the odyssey in with one hand if i needed to.

Is the 680 considered good for a 914-4 in terms of CCA ?

I've only had the Optima for 2 years. No complaints. Note the battery cutoff switch I fabbed. It reduces stress about electrical greblins working while parked in the garage and provides a small measure of thief deterrence.

Yes. Several people have run them both in the 914 and 911 world.

Plenty of cold crank amps, but not a lot of time on the clock if the alternator dies.

I have good luck with the Optimas over 10 years now. I have new ones that haven't crapped out yet. My original was made in USA and maybe the newer ones are from Mexico? Maybe the country of manufacture for this part makes a difference...
