I work overseas and away from home for a month at a time. I always fill my batteries with water before I leave and refill them again when I return. I presently have six deep-cycle wet cell batteries on my MH. There is always one or two batteries that are either completely dry or have a few cells very low on water. My romote in the MH shows that the batteries are being charged at 13.7v.
Each time I return home the green light on my Converter in always blinking. I am thinking on buying sealed gel cell batteries. Is this a good idea?

Why not just buy a float charger like the BatteryMinder Plus? Cost is about $60 - much cheaper than a good three stage converter which also has a float setting.

It will keep the batteries fully charged and won't cause water loss.

Thanks for the info. I will check into in. This may be the way to go for me when we are not using the MH.
Have a Happy New Year

Happy New Year to y'all !!

Since my engine battery is not charged when we are on shore power and it will discharge in about three weeks from "keep alive" current draws, I use a Battery Minder - the url is: http://batteryminders.com/ to keep it float charged.

It will keep up to four batteries charged and I have also used one for orchard equipment batteries in the winter.

Clay - I solved that problem by using a short length of battery cable and an inexpensive battery switch to jump the battery isolation solenoid. With the switch ON, all the batteries (coach and engine) are charged simultaneausly. Turning the switch OFF restores the isolation circuit. Good luck - Dave

On my old coach I found if I kept the charge rate down to 30-50% of full charge rate, gassing/corrosion was minimized as was water consumption. A low rate was fine when plugged into shore power. If you have a charger which will allow this you might try it.

Before I replaced my old Parallax converter with a Progressive three stage charger a few weeks ago, when stopped for more than a few days I used the house battery disconnect switch to keep from overcharging them and having to check water often. A bypass would have meant that the engine battery would have had the same issue.

Clay - For those who spend long periods in a fixed location, "occasionally" bypassing the isolation solenoid to allow shore power to recharge the engine battery is an easy solution. The alternative is to run the engine for hours or attach a seperate charger to the engine battery. As you know, just because the engine isn't being used doesn't mean the battery isn't. On some rigs numerous devices are constantly drawing power from it (engine electronics, radio memory, coach steps, LP detector, etc.). As you point out, permanently bypassing the solenoid does have a downside, including forgetting to turn off the bypass when dry camping and discharging all the batteries, which could leave you unable to start the engine. Good luck. - Dave

Hi Clay:

I think you have made the right choice by getting rid of your Paralax converter.

In the frist three years that I had my coach, I went thru 3 Paralax converters.

First two just up and quit while I was dry camping in Quartzsite, and the third one malfunctioned by putting 16V AC on all my DC circuits--fried several items! Ouch.

Since I replaced the Paralax with an Intellitec 9200 (or something like that), I have had no further problems, and I sure like having a three-stage charger.

Give yours a try for awhile and see what happens.


Cheers and happy travels, Mike www.backroadtravelers.com

My Parallax lasted 10 years 24/7, but last month started making some odd noises. Not the fan but something else. I decided it was time to retire it.

The Progressive Dynamics unit I have now is the Itelipower 9245, probably like yours unless you got one with more current capability. I bought it at RV Lifestyle in Quartzsite. Price was not too bad compared to ordering it via the internet.

Since it goes into float charge when the house batteries are charged (13.2 volts as I write) I shouldn't have to add water nearly as often. I will check it once a month like I have for years until I am comfortable with not having to.
