993 Battery........ Lightweight or Not?

944/951guy · 10-26-2009, 09:33 PM

My battery is dead because the car was in the shop for so long and doesent want to keep the charge so im just gonna buy a new one.
I have a aftermarket battery charging system I will probably be hooking up to the battery because I will probably only drive the car 3-6 times a month.

SO what kind of Battery should I buy and why?
Should I go with a $200+ lightweight battery or is that a waste of money and it will leave me stranded?

Or just go with a Regualr battery?
What brand and where do I buy one?

THANKS!! Paul.

I like my Odyssey 925. I did get a Battery Tender Jr and hook it up occasionally. It's been a year with no problem.

Nice looking battery.
I wonder wounder what the weight diffrence is of the Odyssey compared to the Optima.

bart1 · 10-26-2009, 10:32 PM

The 925 is a LOT lighter than the Optima I have on my Jeep. A guy I know who built ambulances did some serious testing. They went with Odyssey.

DO stores sell them or did you buy online?

944/951guy · 10-26-2009, 10:57 PM

Also does the stock mount work?

Go with a regular battery and a battery tender... There's no meaningful weight savings to be had by using a light battery and then adding a 150 lbs passenger...

Duralast from AutoZone. 7 year warranty with 2 year free replacement. Made by Johnson Controls. Can't beat it!

I got my Odyssey 925T (that T is important) from Battery X-Change on Canyon Rd in Beaverton about a year ago for $170. The factory bracket won't work. Add a Rennline bracket for another $100 and you have just spent a ton of money to loose about 11 lbs from the front of the car. There are certainly better things to spend money on, but I've been happy with it. I do plug in my Ctek battery tender when I haven't driven the car for a while, but it hasn't given me any reason to worry about it.

Paul:

I just replaced my battery with an Interstate 91. It bolted right in, easy. Just make sure they include the vent kit.

I had an Odyssey absorbed glass mat battery in one of my motorycycles, and it was excellent, but I prefer a conventional battery that will (usually) give some warning before it dies. I try to replace them every 5 years, regardless.

I had an Odyssey and it failed after a little over a year. Kept going dead for no discernable reason. Replaced it with an Interstate battery from my local Indy and it's been a no brainer.

Don't waste your money on the Odyssey!

A dead battery is a real pain in the ass, reset radio codes, potential alarm issues, etc. I use a regular battery and a tender....

And besides, having some weight out front and down low, that is not so bad..IMHO of course.

g_murray · 10-27-2009, 10:33 AM

My Sears Die-Hard (6 yrs. old) gave up the ghost last Sept.

Did a search and narrowed down the "new" list to the Odyssey and Optima - yellow or red-top.

Went with the Optima Red top. There was a goup-buy a while back - I think I paid $110 with free shipping. It bolted right in and I've been a happy camper ever since. And yes, it DOESN'T need venting!!!

All this talk of weight saving. Why not just go for a stock battery (Bosch Silverstar here in the UK) and half fill the tank with fuel. 5 or 6 gallons of fuel being carted around must weigh more than the lightweight battery saves. Just my 2c ;-)

I agree that the weight savings is a non-issue. With a heavily rear-biased weight car a few pound(s) in the front is fairly insignificant IMO. I would be more concerned about leakage/overflow possibility. Is it a rare occurrence? Probably, but if you are the unlucky one, then it's really quite a mess. That is why I am giving the Optima a try. If it doesn't last very long, then I will go back and take my chances with a conventional battery.
