New Batteries - Indicator shows Low Battery

[Nye]

Hi All,
We recently bought a 2009 Forest River Georgetown and just replaced the batteries. When my husband installed them, the battery indicator still shows low battery. Any ideas on what to check or what else the issue could be?

Well, they just might not be charged all the way off the shelf from the store.

It might take 2-3 days plugged in to AC to get them fully charged.
