I have a 2025 Prism MBE with dead house batteries.
There are 2 batteries. They each have 24v on the labels but they read 12v each (temporarily) when I check the voltage. They should be replaced with new 12v batteries, yes or no??
 
if you have 24v batteries now then you have a 24v system and should stay with 24. Have you charged them. If a 2025 they may not need to be replaced.
 
The 24 is the Group physical size designation. Letters after the "24" designate terminal layouts. I doubt very much that you have anything 24 volts in that rig unless someone mad a major change.
 
I charged them, it sat for a long time. They don't hold a charge. But Shouldn't each battery read 24v not 12v?
I am confused!

Is the label part of the battery, or a label for the system?

24 volt batteries are uncommon, so My guess is you are looking at two 12 volt batteries in series. Make sure to take pictures before disconnecting anything.

The labels are on the batteries. It is not here right now so I will check it later.

Thanks
