Frustrated with battery replacement
My neighbor's 2008 XB battery gave up yesterday after 9+ years. I took her to Costco and bought the battery according to Costco's book. There is only one choice for XB. So we cannot make a mistake. I put the battery in and the car started up. Fine. However, when I tried to tighten everything done, I noticed that the over-top battery clamp cannot be pushed down to lay flat on the top of the battery. It seems that the Costco battery is slightly higher than OEM Panasonic battery. BTW, there was no size group number on OEM battery. I had to use some strap to secure the battery for the time being and asked her to go to a Toyota dealer to get the correct battery today.
I am wondering whether there is something tricky about the OEM battery? Does Toyota intentionally make the OEM battery slightly different from generic battery so that owners have to get the Toyota battery? Thanks for the info.
