Had a bad battery in the Jetta.
This was a Johnson Controls H5 sized EFB. It was the original battery and rated at 320DIN, 640SAE CA. it tested at 99DIN after charging.
I did some research and found the part number for a AGM H6 sized VW battery and it was over 450.00. So for less than that I decided to go with the Optima DH6. This is a pure lead battery but is not a traditional Spiral Cell we are used to from Optima. (None of their DIN H5/H6/H7 are) I know Optima gets some hate, but I've had good service from them.
The Jetta battery tray has room for the H6 and provisions to install the hold down at the correct position for an H6.
Easy enough to remove. I used a couple of mini bungee cords on the cables to hold them out of the way.
The offending battery out. Though really it gave 5 years service, so I don't suppose I have a huge complaint.
A comparison, though I should apologize that the Optima is sitting on a 4x4 creating the sense it is much larger than it actually is.
The new Optima. They omitted the AH on the label its 72 (also not thrilled about that as you need it to program) but it is on the website.
This battery was not especially fresh on the shelf at AAP, but tested at 100% SOC and SOH and 1211SAE CA. (I'm not sure they love me but I always check a new battery before I leave.) I gave it a maintenance charge with an Optima 400 before I installed it anyway.
Much tighter fit. If you're particular you may want to tape (or remove) the to air box lid. This is where the cables being held out of the way comes in handy, because you will have to drop it in the battery tray and slide it all the way forward to allow the rear to drop down and slide into the hold down moulded into the tray. Once the rear hold down is engaged push the battery rearward and install the front hold down in the more forward position.
Easypeasy.
Now to programming:
My factory battery was set to JCB, EFB, Serial number 1111111111 in spite of the BEM code on the battery saying EMC (Jonson controls Mexico) and having a serial number.
There is some debate on line which I've discussed in other threads but I set mine to JCB (Clarios bought JCB), Fleece, and serial number (the date installed) and 72 AH (the old one was set to 59) The module also did not want to accept alpha characters so I added 2 zeros to get 10 digits.
I'm convinced that the AH, Chemistry and changing the serial number is all that really matters.
Back on the road.
