Crap Batteries

Same here, I think they are $69 at my local Worldwide Equipment. They are also the best batteries I've ever had by far on almost anything. I'll edit this post later with the brand. They aren't Deka or JC, though they could be made by Deka. Seems like I looked in to it when I bought them.

@Midwest Trucker, I wouldn't shell out for AGMs for a tractor personally. They are about twice the price and I really doubt you get twice the life. I never have on campers, just marginally better than lead acid.

 

I remember buying some batteries for $120, thinking they will be better. Nope, 2.5 years, that's all they lasted

 

I have a 21 Cascadia with the same issues. Luckily it has a APU. Would never be able to run the bunk heater all night and start the truck in the morning without it. Even at 12.5 volts, cranking the truck will set off alarms on the inverter and kick in the LVD. Took it to a shop and the batteries tested out perfect.
I am starting to think truck manufacturers are all going to these dual purpose low CCA batteries to be used with Apu's and Opti idle systems. These batteries appear to be useless unless paired with a auxillary power unit to keep them charged. Could be wrong, but something is wrong. Too many people having the same issues for it to be a bad batch of batteries.

 

How many batteries does your Cascadia have? I've noticed more people with 3 having issues with stuff than 4. Volvos, at least, have a spot for 4 but they don't all have 4. Mine has 4 and will always have 4. Hell, I'd put 5 on the thing if there was space.

 

It has 4 Allied dual purpose. Not sure what the CCA is but it doesn't seem to be enough. Even in warm weather it seems to spin over slower than what I'm used to.

 

Exide is the third big manufacturer. They at one time made the paccar batteries. Maybe still do. I had along with others horrible service out of paccar or anything Exide.
The Alliance worked well for us and I believe that some were Johnson Controls.

I’ve used Interstate in the trucks and optima in all the cars both made by Johnson Controls. Great service. Some of the optimas are approaching 20 years old.

I just had one Interstate out of three go down in my Pete the week of Christmas and it was a 2011. The shop I get them from has switched to Continental Batteries because Interstate was raising the prices so high and giving him back less then the core fees that he could not make a profit enough to make it worth his while to stock them anymore.

I’m gonna try Contenental and see. They are out of Dallas since the 1930’s. They also make the Optima now for the company Johnson Controls sold that too.

 

For lead/acid batteries I’ve always had really good luck with anything PennDeka makes. I prefer not to go over 900ish cca as the plates get to thin and are prone to breaking and shirting out the battery.
