I've a battery that's bad in a two battery parallel bank. Both AGM's with a smart charger. I don't really understand why I would need to have two new batteries and couldn't I just replace the one AGM with a like size but brand new?

Thanks for your time.

Mixing batteries that are not the same size, made by the same manufacturer, and hopefully made in the same production batch is a mistake.
