Chassis batteries

[Rusty years]

Hi all. One of the 12v chassis batteries went bad and a neighbor mentioned that both have to be replaced at the same time. Seems the older battery will draw down the new one to its level. Any input?

That is correct. The new battery will drain down to the old battery. Batteries should always be the same age when new so they can all work together.

Good advice.
Having said that, when you go to purchase new batteries, check the date code on them to make sure they are the same and are recent manufacture date.
I have seen batteries on the shelf in the big box stores in particular that are a year old sitting on the shelf. If you are buying new, you might as well get New..

A s usual, there are other things that are in the mix. How old are the batteries? Do you dry camp and run the batteries down before recharging. Do you keep the batteries on charge while in storage. How many times have the batteries been discharged and allowed to stay in a run down condition for a number of days or weeks. If the battery was never run down and is less than a year old, I would not be hesitant to reuse it. If it has been subjected to any of the other conditions, I would replace both.

I once ignored the advice to change all house batteries at once. It took my 6 months of further frustrations to finally do it and resolve my problems.

Just do it.

A battery pack is as good as the worst battery in the pack. The bad one will drag a good one down to its level. Replace all with like kind and pretty close to the same age.

Thanks everyone. The batteries are over 2 yrs so I will replace both.
