So easy question of the day. i am going to change my battery later today and it would save me some time to know what size wrenches and sockets I need to do this. I left my trunk open last night, charged my battery this morning and it is to low to start my car after sitting for 6 hours. Its almost 5 years old. For a battery thats not to bad. Anyway my car is stuck at work and I would much rather take a few wrenches/sockets than my whole toolbox. Thanks guys.

 

On ALL of the imports I've known it's been a 10mm, both for the terminals and the battery tie-down. But I have yet to do a battery change in the Lexus ('06 350 on OE battery myself).

So I'd bring a 10/11/12mm box-end wrench to be on the safe side. I assume it's just a matter of removing the battery tie-down, removing the terminal clamps, and remove the battery.

What group battery are you getting? I've heard that not all are a perfect fit in that "protective sleeve".

 

I was going to have autozone test it first but I figure its gone. I think they have DURALAST batteries. I would probably get the DURALAST GOLD. Do you know if it will fit?

 

I just changed my battery a few weeks ago. I got a group 34 battery because the dimensions fit the OEM battery the best. It's shorter than the OEM battery, so the metal tie-down doesn't hold it as securely. I don't remember off the top of my head, but I'm pretty sure it's 10mm bolts for the terminals and tie-down
Just a note, the plastic sleeve is kinda a B to get off. You got to pry the clamp on the positive terminal: https://www.clublexus.com/forums/is-...ion-is350.html

 

^ Yup, you only need a 10mm (socket > wrench). That plastic sleeve sucks.

 

i threw my plastic sleeve away

 

Same. It was a bit tall for my new battery, and I didn't like it very much to begin with lol

 

10mm and go to costco to get the battery

 

I changed mine in 5 minutes. I was aware of the plastic sleeve problem but I got around that easily. All you need is a 10mm wrench and an exacto-knife/blade, or anything like it. Trick with the sleeve is that the postive terminal wires are connected to it, just use a knife and cut the folded part of the thing holding the wires, and pull the wire out.

I bought the Duralast Gold battery and it's great. It fits into the sleeve but it looks really sloppy since the handles make the sleeve bulge out on the sides. I just threw away the sleeve and it looks much better.

Using another person's image, just use a knife and slip it through the circled part. You can pull the wires out once cut and slip the wire back in once done if you keep the sleeve.

 

i switched to an optima yellow top because i have an aftermarket audio system, i have a oem panasonic isX50 battery that was replaced by the dealer in i think 2009 under warranty...worked perfectly if any members are goin to be in fl or live in fl ill let it go cheap, until then its sitting on the floor of the guest room free of the harsh outdoors!

 

I had a new Interstate battery installed at Sam's Club for $77 (tax & installation included). It is Consumer Reports' top rated battery for our group size. I am thrilled with that for $77.

 

Our Sams now has Duracell.

 

How's the warranty at Sam's?

 

They give the same warranty that the manufacturer gives.

Thanks for the advice, folks - i just changed out my battery with a kirkland (costco) battery. I cut those damn positive cable connectors off and tossed the entire sleeve. Why Toyota put that there is beyond me. Completely unnecessary, IMO.

Oh and everything was 10mm.
