Yeah, one of them is junk.
Don't forget the ground circuits!!!!
Always replace batteries that will be paralleled for use in date matched pairs for best results.

Manufacturer date codes are "stamped" into the battery case.

The Optima Yellow top is a good choice for no charging system, or if you can fit them, use the Group 31 truck batteries, they hold up to vibration much better than a regular automotive battery, and have great reserve capacity, which is critical to operation without an alternator.
