I recently changed my battery to the optima group 25 as well( although I didn’t think of Keeping the sticker!) but I nor Sanderson Ford was able to get the rubber block that held down the original battery (8mm bolt) to grab hold of the smaller lip on the Optima group 25. the Ford GT tech( only one in Arizona) couldn’t get it to hold onto the new battery, ideas???
I would seriously doubt that. We've installed 3-4 Group 25's in the past 5-6 weeks. Make sure the foot is on correctly.I tried that myself so that is why I took it into the Ford GT tech and he couldn’t get it either. Perhaps they changed the bottom platform of the group 25?
so battery replacement went very easily. Bought the Optima Redtop 25 at oreilly's auto parts for 91 bucks, had it in stock.
To be safe I would get another 12v lead acid battery and fuse it with 10 amps and plug it into the accessory port. The fuse may be redundant as the accessory port has one as well. This will protect you from things lights coming on by design or accident. If I remember correctly the quiescent current is about 20 to 50 ma and less with the car locked (strange). But open a door hit the brakes, touch a switch then SOL!
There shouldn't be any problem to do this. Make sure the battery is all the way forward and make sure the "foot" a the end of the long bolt is on correctly. We've done dozens of replacements and always get them clamped in well.
Unless, as I have done and dr419 said in his post that I replied to, that he had connected the battery tender before changing the battery. In my case the emissions adaptives were retained. I was merely asking that poster to confirm.That's really a moot point, right? A battery replacement will reset adaptive learning as well as emissions monitors. Always.
