Car was taken out of winter storage. Always on Ford battery charger. On second battery ( diehard, about 7 yrs old). I replaced the battery when tach went. Replaced it and all small gauges with auto meter replacements. No problems until first startup. I always “ prime “ motor first after long storage. Started immediately after priming and battery seemed good. However tach and speedo not working, and check engine light on. Car ran fine, start stopped few times, Speedo worked once, not tach. O k battery change time!
Read manual on battery change ( 05 car and workshop manual) . I read about removing battery from above, Long reach and watch the fenders) I am 5’8”. Manual states remove front spoiler, I thought remove battery from below? Took it off, NO WAY!! Other shields etc. replaced it from above, no problem!
While removing battery , kept ford charger plug in. Started car up, gauges working, No reset needed, check engine light off!!
In summary , change those batteries ( every 5 yrs?!). Also 05 workshop manual has mistakes. 05 manual oil change procedure has mistakes, which were corrected on the 06. Those of you who have 06 manuals please check to see if removing front spoiler is described! If so I am getting an 06 manual!

Optima 25. Easy fit, dimensions like original and no issue with battery hold down bracket.

I have a 05 manual and a 06 manual, have yet to find any differences.

It's more than like the original. The original is an Optima with a Ford label on top. At today's prices the Optima is half the price of the Ford (if you can get it)

Look up wheel torque specs. My 05 manual has two different specs in different sections of it. I think I found a couple other discrepancies too. Rotor screw torque? I think 06 fixed those. IIRC

Follow up on 05 and 06 workshop manual changes. I purchased 06 manual, sure enough describes battery change from above ( not below like 05 manual). As stated above different description on oil change as well. The 2 most common maintenance procedures. Can imagine about the rest of the 05 manuals! Would highly recommend updating!!

I swapped mine out a couple days ago with a new Optima. What a PITA job. That plastic hold down block was a dumb idea--having to fish around in there to get it lined up with the long bolt with the battery and frame blocking access, while bent way over, and avoiding leaning too hard on the fender. I think I pulled the battery out 3 more times to retrieve that block and get it lined up properly. Next time, I'll glue it to the battery with a glob of silicone sealer first.

The trick is to push the whole battery forward a hair and it drops right in.

I have a string tied to the bolt so when it falls in, I can pull it out easily.

But my last couple Optimas have had short lives, so I am in there more than I want to be.

Next time I will try the Odyssey.

I'm inclined to use the Odyssey as well, many bad reviews on newer Optimas including from my local battery supplier who won't even sell them anymore. Still available obviously from the large auto parts houses.

Perhaps discussed before, is the Odyssey the same size or does it require any persuasion to reside in the battery compartment?

my original optima lasted from 06 to 2019. The second one lasted from 2019 to 2021. The third lasted from 2021 to 2023. I am now on my fourth one

Mine lasted from 2011 to 2018. It was on C-tek (Interstate Battery) trickle charger from the beginning.

Obviously, he's done it a few times before! I like the string idea.

I want to avoid any trauma (to instruments, etc...) when doing a battery switch. Are you guys using any "OBD memory saver", or some specific technique (negative off first, on last)?
