How to install a new optima group 35 battery in my 2007 Toyota corolla?


Asked by Jun 10, 2015 at 05:37 PM about the 2007 Toyota Corolla

Question type: Maintenance & Repair

I bought a new optima group 35 battery for my 2007 Toyota corolla but the battery hold down doesn't fit. The new battery appears to be a bit skinnier and a bit shorter. Was the guy who sold it to me and this site just wrong? I went looking for a universal hold down and was told that none of them would work for corolla batteries. Am I just out of luck? Any thoughts would be much appreciated, thanks!

Group 35 is correct. It should measure 9" long, 6.88" wide and 8.75" in height. But the tie-down allows for some latitude from that, the way it is there is room on the tray and the tie-down does not have an absolute measurement for it to work. Check the physical size of the battery you bought

Thanks for your help! Yep, that's the one, it's specs are - Length 9.31 inches Width 6.81 inches Height 7.62 inches and it was recommended on this page as a replacement -

Well, the recommendation you got was for a much more expensive battery than you need. It's a deep-cycle also, not necessary. You were sold a battery that if you can get the tie-down to fit, the battery will be fine but an Interstate Group 35 wet battery would have been better.

I have that green-top Interstate in my 2006 Corolla. The 550CCA and it performs as well or better than I expected.

Thanks! Yeah, it seemed expensive, but I reckoned as long as it was a good battery I didn't mind paying for quality. It's been in my car with the ill-fitting brace as my original battery was dead so I'm a little concerned about whether I can return it. If you have any ideas on a tie-down that would fit, or how to make up the space, I'm all ears!

There are a couple options on that. The rod that comes up from tray is too long, right? If so, you can buy a die of the proper thread/pitch and cut more threads on the rod. (I don't know what exact size, something like ΒΌ/20 but not sure, but will be close to that) and for that matter won't be SAE but metric. Anyhoo... that should solve the height issue, but if it won't work for width...ummm..redneck way I have used for years, a bungee or two. The battery is heavy enough that if you don't have a habit of off-roading, and a Corolla is indeed a highway car, there are millions of cars with rubber bungees for battery tie-downs. You will be fine. But try the die on the rod.

PS. The battery itself is fine. matter of fact very good.

Yepl that's exactly the problem with the rod, I'll give it a try. Thanks again for all your help!

Good luck hellboy.... you will be fine. Get the die and use plenty of WD40 or really any oil. copious amounts. Thread a half-thread and back off a full turn, and repeat until there are enough threads. ..And if I may, you have the right for quality. I think the same way. Inexpensive= junk. *Usually*
