Time for new batteries for my AF811

The last 2 years or so, the original batteries in my 2010 AF811 have pretty much been useless. I haven't used the camper much during the summer of 2013 and 2014, and most of the time I had shore power during those 2 summer. Part of the time I had decent sun coverage so the solar provide my DC power needs when I didn't have shore power - at the NW Overland Rally last summer. I pretty much had to run the generator after dark until it was bedtime - that's how bad the batteries were last summer at the Rally.

I'm at the point where I can't tolerate the poor performance of the batteries any longer, particularly with the need to take a few trips and use the camper the remainder of the winter. I've already decided on AGM batteries. Why? Because checking / adding water to batteries is a total nuisance. I have to completely disconnect all the DC connections and remove the batteries from the battery compartment, and doing so when the camper is on the truck isn't fun - a ladder is required.

I already have a decent 3 stage charging system - a Xantrex (aka Statpower) PS2.0 inverter / charger and the smart remote for it. I can tailor the charging regimen for AGM batteries.

I know that I've murdered the batteries due to lack of maintenance.

I need to start taking some measurements to see if the batteries from DEKA I have been eyeballing will fit the slideout battery tray.

I've procrastinated this long because I just don't (hadn't been) using the camper enough to justify the expense of new batteries.

I started the same project 3 years ago and have never finished it. I even have the wiring routed on the truck. Part of the procrastination was caused by not knowing how to get heavy gauge wire from the camper batteries to the outside of the camper.

Back to the batteries: I special ordered some group 31 AGMs from a local store - the store I priced them at last week. They are the same batteries as the Deka batteries, but with a different sticker on the side. They are due to arrive at the local store tomorrow.

I started a similar thread a few months ago and based on recommendations here I went with 2 of the Universal 100AH AGM's from Bestconverter and am happy with them. Regarding the terminals, I had to buy longer bolts to get the nut over the 3 things that are stacked on (house, generator, solar), but other than the too-short bolts I don't see a problem with them.

UPG has been around for a few years... For AGM's >< 6 years.

Connections issues are true with lifelines etc....

Bestconverter has been around for over 12 years... I think they stand by their products and will still be around to take care of any warranty and Issues you may have ...

I beat the S**** out of a new one years ago and it still is working from what I have been told.
That is another story.

It looks like a nice setup - you probably meant to say PD 9260 converter.


Yep that is what I meant. I've got all of the parts now to do a proper 4 gauge charge wire install from my alternator. I will find the time to do it all this spring.

Might just look at this, no tax and free shipping from Bestconverter..

Several folks are using them and are happy.

Shopping today:

Group 31 deep cycle batteries are not a normal stock item at retailers. Maybe they are at RV dealers.

My AF has group 29 Interstate batteries in it.

Stop 1: North 40 (used to be called Big R): Group 27 Durastart AGM, which looked exactly like a Deka, $165.99
Sidebar - there were various powersports batteries with the Deka name on them, and various East Penn Mfg battery application guides laying on the battery display rack. East Penn=Deka.

Stop 2: Costco: group 27 FWC (Interstate brand) for $88.xx

Phone call: Deka Warehouse: Group 31 Intimidator AGM, $285.xx retail. $240.xx ish with my wholesale discount when I fill out a dealer app. $240.00 is the same price as the link provided earlier.

Stop 3: Batteries Plus (aka, Batteries `n Bulbs): New fangled Group 31 AGMs from Northstar private labeled for B+, $335+
They didn't have Lifeline. Lifeline's website shows them as being a Lifeline dealer. I didn't ask about the Lifeline brand when I was there.

So after all the above was done, I stopped in again at North 40 on my way home. I asked about group 31 AGM. The asst manager called the warehouse, which happened to be the Deka Warehouse. North 40 can get me the group 31 AGM for $175.99 each.

Glad I stopped there before the other places, because it got me thinking about the Deka / East Penn catalogs on the rack there.

This is why when I have a big shopping expedition planned out, I always stop at the closest places first, and each stop after that is in consecutive order per my travel route, then I can stop back at previous places on the return leg without backtracking.... unless of course it was a trip made in a big circle.
Today's journey was an "out and back" expedition.

Over the last few weeks, I've sure been getting the urge to pack up and travel for a month or so.... but it's not practical at this point. There's too many upgrades my big trailer needs to make it a more usable long term man cave / toy box for a big trip.

I'm kind of that way too.

Here's my first monitoring system, in a 6x10 trailer I used as my first "RV"
This is the trailer I had the Group 27 Prevailer gel battery in, then later I added a surplussed 4d gel battery that I obtained while working at Heart.

Yes, that's 3 Link 10s. One monitored just the input from the solar, each of the others monitored the two batteries.

I had 200 watts of solar on it.

I didn't make it shopping today. I wasted a 1/3 of the day waiting for UPS to show up so I could get some product to reship as well as have the UPS driver pick up to packages that can only be given to a driver or taken to the UPS depot 20 miles away, and I didn't want to drive there.

I may just pull the single Deka AGM battery out of my 8.5x20 trailer and use it for the trip next week. Unsure yet.

So my question to you, are you guaranteeing that your days of lack of monitoring and maintenance are behind you? Are you going to have the batteries plugged into a trickle charger and for FWC batteries check the fluid every month, during periods that your camper is not being used? If so, go spend $400+ a battery, for the Lifeline/Deka. If not, just purchase the largest Group Battery that will fit in the area where your battery fits, at your nearest battery seller for lower cost.


Monitoring is good - I watch them closer than probably any truck camper owner, except you. ๐Ÿ™‚

Maintenance is the problem, due to the difficulty in doing it.

After reading your post yesterday, I've done a lot of thinking about cost / vs maintenace between wet cell and AGM. I'm still on the fence at this point because I keep thinking how hard it is to pull the batteries during camping season to check the water. The slide out tray doesn't have the ability to slide all the way out to expose the back battery without complete falling out of the batter compartment - so this necessitates the disconnection and removal of the batteries to check their water level.

I keep the camper plugged in all the time at home, except right now, because there's no need to since the batteries are toast. Otherwise, whether in storage or in use, batteries are kept at a decent state of charge unless it's dark out (no sun) and I'm alseep (no generator).

I've got solar, and when dry camping in the shade, I use a Honda EU2000i to keep the batteries up.

My knowledge of batteries, monitoring, charging, etc goes back to my younger years when I spent 8 years work at Heart Interface (inverter company) which is now known as Xantrex.

sidebar: I am completely lost with what the acronym FWC means in regards to batteries.


FWC = Flooded Wet Cell

Yep I am, and have been all my life, obsessed with data and the watching trends and changes of so many things. I have tracked my solar harvesting for 4 years now and was able to determine when my original 7 year old AGM Eagle 6v Batteries needed to be replaced, weeks ahead of their final demise. That way it was not a shock when it happened and to my checkbook. I was able to purchase them in a Sales Tax free state, just to save some $$. It is also good to have a record of maintenance and Equalize times, as well as other events, such as when people stop and visit in remote locations. While there is ways of digitizing this information and using a HUB to use one remote monitor, I donโ€™t. Because my trailer is disconnected often, having a type 6 connector is difficult. So it was just as cheap to have the three monitors.










I am a proponent of saving money and using things simply and efficiently. So going solar and in my case, more solar, is not always the answer. So yes, evaluate whether it is something you will use. You mentioned about parking in the shade. Well, that is one of the reasons I have solar on my trailer, in addition to the roof of my truck camper, to park it in the sun and my truck in the shade and have, many times. Options and redundancy.

I am going to go battery shopping and get prices on wet cell batteries today or tomorrow.

I blew past the exit Sullivan Road on I-90 yesterday on my way back from Post Falls, and didn't realize my error until 3 miles later. Sullivan Road is where the Deka warehouse is.

Using a smart 3 stage charger, causes batteries to gas a little bit more when charging, since the voltage is higher than the typical "dumb converter/charger" used as OEM equipment. This result in the water level needing replenished more often than when charged on a dumb charger.

Once the plates are exposed to air, things go south.
