Another thing to consider is that it's not always a gentle decline. You might start to notice weaker cranking and think it will just keep getting weaker and weaker. While that might be the case, I've also seen it plenty of times where they go from fully functional to done from one start to the next. So, you might not get a warning... Anyways, I've been very happy with my Odysseys that I installed a couple years ago now. Batteries are like tires to me. I'd rather replace them a little early and forget about it than try and squeeze every bit of life out of them and have the risk an issue in the back of my mind.

My Odyssey battery (maybe all AGM's?) was very good at giving me a good amount of lead time before it failed. It failed slowly. I've read that it's a common property of the Odyssey batteries. However, I did read that on the Internet, so take it with a grain of salt.

The batteries came in but my buddy was slammed. Plus I had a side job to go to at 1700. They'll be installed next week. Going to get cold tonight at 2 deg so going to put the block heater on. See you guys soon

hmm might need them for my '19 I am on my 4th set of motorcraft batteries. might be worth buying the extra warranty to get new batteries every 8 months.

Those Interstate AGMs were installed yesterday. Man, I didn't know my truck could start that fast! We're getting some snow tomorrow so I'll see what it's like to have fresh batteries in when plowing. I definitely needed them for sure.

Thanks Rod...
My buddy only charged me $350 but I made him take $400. He wouldn't take more. That's still under retail.
I'll have to be buying lunch again soon.

I've never had a problem with my Motorcrafts because I get my truck oiled every year at Carwell. They spray under the hood as well and the batteries. I also coat my posts and connectors with an oil based product. Not the cleanest but I've had no corrosion issues at all and no problems with corroded battery brackets at all.
I just asked my buddy whose shop stocks Interstates about AGMs he replied that he really sees no extended life out of them but to me, maybe the advantage is no corrosion issues. He said his going to talk the battery guy and see what he says.
Yesterday morning it was 5 deg out and the truck cranked slow at first but did start. So before I went home from work, I went to Advance so they could test the batteries. They disconnected the positive connector on the driver's side battery and tested the passenger side. Voltage was good but cranking amps read 505 amps. Definitely not 750 amps. They wanted to test the driver's side but I said no. It didn't matter because if one is bad, I'm replacing both, not just one.
Last night I plugged in the block heater. Truck cranked over real nice. But it was 21 deg. So for now, I'll just keep plugging her in to make it easier for the batteries.

I checked this morning and the passenger side battery hold down clamp is being attacked by battery acid.
I had cleaned and greased the battery terminal posts before installing as well as the battery cable ends.

I bought two new Motorcraft batteries last year. And two new battery hold down clamps as the existing ones were being eaten by battery acid. I checked this morning and the passenger side battery hold down clamp is being attacked by battery acid. I had cleaned and greased the battery terminal posts before installing as well as the battery cable ends.
I have my truck oiled by Carwell Products which is specifically designed to prevent rust and corrosion during our cold winter months with the use of salt on the roads in the winter time. They also spray under the hood and all the wiring. The batteries tops as well. It's a light red colored oil designed to creep into everything. I'll take a pic of my hold down brackets when I get chance with the new Interstate AGM batteries and post here.

The light oil that Carwell uses did the trick in protecting the brackets.

Nice! I didn't get that lucky, I sprayed my batteries with fluid film (maybe not frequently enough) and the factory batteries still corroded the brackets.
