Two identical RV batteries. They have been unhooked from the RV

Why
this discrepancy when the hydrometer readings are identical? Obviously, I
will replace the low voltage battery, but, I want to learn why the
hydrometer readings are in discrepancy with the voltage readings. BTW,
checked the voltmeter against my truck battery (everyday use). It reads
13.2 volts with the engine not running.

Thanks for all replies,

Sounds like it has a couple shorted cells.

Yep - The low voltage is close enough to perfect for what you'd expect
to see with exactly two shorted cells.
