Battery

today I finally got around to checking my chassis battery it is a motorcraft and it has a eye on top of the battery and it is red what does that main replace battery or charge battery and also old battery has 650 cranking amp, the new will have 850 cranking amp will that hurt anything on the coach?

Will be fine with more cranking amps.

Having a red eye doesn't necessarily mean the battery is bad, just that it is low on charge. You will need to have the battery tested to be completely sure on it's life.

Replacing with a battery with higher CCA rating battery is not a problem.

I just replaced mine and it was red. Green when charged up. You can check the water and try to charge it, but it may be done. Mine was 8 years old.

Mine is an E450SD. Takes a group 65 battery, trying a NAPA AGM battery.

back when I had a battery with an eye I think it meant "Sufficently charged to test" Pretty much if it's older than 5 yrs it's done with.

If you need to replace it you might want to consider a cheaper alternative. Sam's Club and Walmart have some at a lot less than you'd pay at Napa, Interstate, or somewhere like that. I just got 2 deep cycle batteries- group 27 at Sam's for $85.00 apiece. Napa's were about $120.00 I think. Starting batteries obviously will be cheaper anywhere.

I took my battery to the shop and had it recharged and then check it and I had to replaced it

[A32Deuce]

Yep! Get the red eye pretty much toasted. That's how mine was!

this battery was not that old it came with coach but the coach was a 2016 chassis model

A lot depends on use. We are out in ours once a month for maybe two weeks. The battery is used a lot then. If it sits for weeks at a time and does not get fully charged, then its life is shortened. Just sitting there are things drawing current from the chassis battery. Longer they sit the lower they get.
