Maintenance To Deep Cycle Batteries?

[Edmo]

I️ have a 2016 FR 3 and I️ noticed on the panel that the battery level dipped one bar. The battery recovers after the generator is on or the rig is running.
Is there any maintenance that needs to be done to the batteries.

Thank you

One of the reasons I have not done the upgrade on my iPhone. Depending on the type of batteries you have you may need to check the water level. use only distilled water to bring up levels on cells that are low. Of course this is only for batteries that are not sealed.
