overcharging batteries.

What’s the thinking. Should I disconnect the batteries when we part the Rv and are not using any power? Since the batteries are not connected with a smart charger ie a battery tender or minder are the being over charged. I’ve seen this happen many times in industry, a trickle charger left on constantly.

Your converter should take care of the battery while you’re gone. I don’t disconnect mine when we’re away for extended periods. It’s the original battery and it’s still doing fine.

The Power Converter in your Bighorn has 4 modes so the battery is properly maintained. You should check the battery water level every month or two.

Yup I understand the converter keeps the batteries up, but if it continuously keeps charging it can over charge. I wonder at what rate it charges the batteries. I guess if you still have the original batteries it’s ok 👌

Thats the info I was looking for Dan. I did add one of those central watering things, so I give it a squeeze every month.

I'm assuming that Heartland is still using the Progessive Dynamics PD9200 series converter/chargers. If you read this information page on their charging logic circuits, you will see that your batteries are better off continually connected to the converter/charger due to the desulphation effects of the equalizing mode that happens for about 15 minutes every 21 hours. https://progressivedyn.com/rv/charge-wizard/ . I can tell you that your batteries can last a LONG time with continual use of this charging system.

Just make certain the lead acid batteries have the proper amount of water at ALL times. Trickle, 4stage auto-chargers and solar are the best way to keep the charge to proper levels when unattended. Battery life also degrades when the batteries are left less than 80% charge.

What in the world is this "central watering thing" for batteries?

Thats it, the $59 one. A little pain to install, but the ease of servicing the batteries is worth it.

. . . or buy sealed, maintenance-free batteries, or sealed AGM batteries. I bought a couple of used, tested, AGM batteries for about 1/2 new price from a power wheelchair rebuilder I found on Craigslist, and I have had those for about 7 years now (with the PD9200-60) converter/charger.
