Batteries are barely charging!

[1strecon]

Noticed our Lithionix batteries are not charging very quickly.  We have been taking the batteries out during the winter months then re-installing them in the Spring.  Any ideas as to how best to trouble shoot what’s going on?

What's your hull number.  
How are you charging them?   Are you charging from shore power using the on board inverter/charger?

If you're running from a 15 amp circuit plugged into the trailer you may need to change the settings on the charging part of the inverter charger.

A little more info will help us troubleshoot.

Have you tried contracting Lithionix?

In addition to Galway Girl's important questions:  How are you measuring charge rate and charge level?  Are you using the Lithionics app, the Victron Connect app, the SeeLevel gauge next to the pantry or a multimeter?

Also, are you charging using the solar panels?  

This additional info will help us help you.

Hey John, this guy is OK. He's Matt Marcenelle, Retired Military, Wife is a retired Coast Guard Commanding Officer. Son just graduated from West Point. They live up in Pennsylvania and have had their Oliver 4-5 years. I met him the week he got his trailer. He called me this morning about this issue. It seems to be charging fine off AC but not so well off Solar. He did have his panels off earlier this summer for ceramic coating of the trailer. I told him to recheck his panel connections and if that didn't work to call Victron. I really don't think it's his batteries. He has a Xantrex converter/charger that I know almost nothing about. Hope you guys are doing well. Will we see you in Quartzsite this winter?

Seems like sound advice. Did he shut off the solar disconnect switch to remove the panels? Did a solar charge controller setting get changed? Victron or Zamp?

Thanks Steve! Always look for issue with your most recent change.

That's a good thought about the solar cutoff switch. I don't have one and rarely think that when trying to figure out someone else's problem. I'll call him as ask. Thanks!
