Sounds like a bad inverter/ converter.

See the Owner's Manual for your inverter/charger, then check and set, (or re-set), the "charging parameters".

You are in Florida so there may be nothing wrong with your charging system and you could just have old batteries that need replacing. What brand batteries are we talking about and how old are they? I have found that the Walmart EverStart deep cycle batteries last about 2 years in the Florida heat and then their done.

Even after upgrading to a Progressive charger/converter with the Charge Wizard the Walmart Batteries still would not last more than two years here in Tampa Bay Florida.

Check the battery voltage after they are charged and see if it stays around 12.8 for a hour or so with no load or just starts dropping down in short order to 11 or lower.

If "the Walmart EverStart deep cycle batteries last about 2 years in the Florida heat and then their done",
IMO either:
1.) You don't have a 3 stage automatic charger in your inverter/charger.
2.) Your charge settings are wrong.
3.) Your inverter/charger is bad.
4.) Walmart batteries are no good in the 1st place.

In my coach, the original 4 Interstate deep cycle 12V house batteries lasted 11 years......
the second set of 4, (which are Northern Batteries), is 6 years old.

My coach always has shore power, (except when traveling or boondocking), therefore the 3 stage charger in my Freedom 20 inverter/charger is nearly constantly monitoring/maintaining my house batteries.

BTW, I check the electrolyte level every 3 months but I only need to add water every 6-9 months.

Search here for battery troubleshooting chargers and maintenance.

Many do not like responses like this but batteries are very common threads and there is enough material on this forum to keep one reading for days.

Read up then apply what you learn to your situation and take notes.

Come back with questions if you have them but have good questions with data that we can use to help you.

My replacement batteries from Walmart lasted as long as the original Interstates, warm climate and all.

Do you have a solar panel? Does it have a charge controller? In our case it was not the inverter/charger that went bad and was letting the batteries over charge it was the solar controller that was not telling them to stop charging.
Not sure if it's true but the Interstate store guys when we bought new ones told us that since the controller was the original from 20 yrs ago that there was no "stopper" on it to tell it no more. We got a new one and no more problems.
Yes we did end up changng out the inverter/charger but that was 9 months later. And that was cause it was only a 1500 watt mod wave and the microwave/convection oven was wanting 1600 watts, ended up breaking both and needing to replace both.

You can count me in the group that doesn't like this kind of response.

Who gets to decide if a question is a "good question" or not?

Have a very special day.....

I have a PD9260C - 60 Amp RV Converter/Charger with the Charge Wizard Pendant:

PD9260C 60 Amp RV Power Converter Charger from Progressive Dynamics

Converter Status Remote Pendant

http://www.progressivedyn.com/prod_d...ndant_card.pdf


After 3 sets of Walmart batteries I agree that they are junk. I do not full time and the coach is not powered up in storage so I have to start it up monthly and run the generator or go plug in somewhere to keep the batteries going.

The original Interstate batteries lasted quite some time even on the old Magnum Charger/Converter however it was when I went over to the Walmart batteries and started having failures I was told obviously it was the Magnum units fault so I replaced it with the Progressive Charger/Converter. Now that the Walmart batteries are gone no more failures. Could be that the local Walmart supply chain is sub-par but...

Right on TQ60. I also frequently get in trouble for being too direct. I've come to realize that many posters just want to talk, like around a campfire. Also, if everyone that really wanted information, and used the search method, the lower participation could lower the income of the forum overall.

IMHO

Bad question
Why are my batteries dead ?

Good question
We have a set of 2 year old batteries with a brand x converter the does not seem to charge the batteries. I have a voltmeter but need to know best process for confirming voltage and what range should it be.

One could search a little and know what the voltage should be but we should not expect everyone to have the skills to understand what the results of the search but they should be able to get enough understanding to ask a question that will focus on the issue instead of how to determine the issue before troubleshooting can begin.

Your batteries are dead because they are;

1- Damaged beyond repair.
2- Not being charged by the inverter charger.
3- Load exceeds the capacity of the inverter charger.

Check the following;

1- Plug the coach into shore power and confirm you have 120VAC at the inverter charger.
2- Insure that the inverter charger is in the battery charge mode.
3- Using a VOM, read battery voltage before powering and after powering the inverter charger. Note any difference.
4- If the inverter charger is operating properly and configured to charge batteries, you should read in the neighborhood of 14 VDC when charging.
5- Power off the inverter charger and apply a load to the 12 VDC system like lights or some other 12 volt appliance. Again, read the voltage at the batteries. You should see 12+ VDC at the batteries. If not, your batteries are worn out.

If the inverter charger is not charging, you'll need to replace it. Repairs are usually not economical.

I recently replaced the inverter charger in my coach with a used AIMS Power 2000 PSW (pure sine wave) inverter charger off their website, free shipping, full factory warranty and am very pleased with the performance as well as customer support. My house batteries have never been happier.

I see. So, everyone should be required to pass an RVT (similar to an SAT) before asking a question on your forum? That way they won't waste your valuable time.

How about letting those who wish to try to help the obviously less informed or less capable RV beginners, go ahead and offer help, (or maybe ask the OP for the missing information), and you can just sit back and keep quiet? Would that work, you think?
