Ok Folks, I went to a Battery store today to pick up 2 - trojan T105 batteries and the manager who turns out to be somebody I checked on and learned he really knows his suff, recommended I take a look at this battery.

I left and told him I would do some research and be back.

He thought one of these might be a better choice?

Have any of you had any experience with this battery????

Thanks
Dave

A) it's a hybrid battery, NOT deep cycle. There is a difference, and it matters.

B) and most important, a Group 31 will not fit on the battery rack of a pod.

AGM batteries have their place, but it's an unneeded expense. It's only a 100aH battery, so two of them will give you 200aH's, but because I don't believe any hybrid battery can be a true "deep cycle" I would never take it past 50% SOC.. so only 100aH's usefullness (IMHO). Dual T-105s will give you around 200aH's before the battery starts to get damaged. Repeatedly.

It also costs twice what a T-105 does.

Thanks Furpod for the quick reply.
I had done a fair amount of research regarding RV batteries and had not run into much about these, and I thought that in its self says something.
The one thing that did catch my attention was the shorter charging time which meant less hours of running the generator.
He also pointed out they were built to handle bouncing around and I thought how much more bouncing could you get than in a golf cart?
There was a few more things mentioned but his comments made me hesitant to buy the Trojans. I am new to RVing and anxious to get started off on the right foot.
Wife and I spent 40 plus years in a tent and I am now retired and looking forward to numerous trips this summer in the Rpod.
Anyway I walked out of there a bit confused and frustrated.
Thanks
And Have a Great Day Sir

I have a single group 31 on my trailer and it fits between the rails. It's a liquid battery, and cost $90. At that price I can replace it every 2 years and still save money.

Is it in a box?

Maybe I am confused a bit since I last paid a whole lot of attention to pod batteries, But it could be my problem with group 31's was you couldn't get 2 on the rack, a single may fit.

I'll throw in my $.02 and more or less echo furpod.

If you want the MAXIMUM available power between charges, then the 2 Trojans are about as good as it gets - performance vs. price.

That said, I run 2 group 24 "hybrids" ($150 total). They fit my "style".

Though I prefer primitive camping, really, most of it is done with electrical hook ups available.
In the places where it is not, most have campsites where generators are allowed.
I have one of the quiet generators and only MUST have enough power to last thru the "quiet hours".

If I am not running the furnace, transmitting on my radio, or watching a lot of television (I use an inverter), the batteries will last for several days between charges.

IMHO, the best way to approach the "battery problem" is to ask:
How much power do I intend to use?
How often and for how long (each time) due I want to recharge?

A battery does not "make" power - it is just a "storage container". If you take out/use 50 amp/hrs, at some point, you got to put those electrons back in. The WFCO converter/charger is going to charge at a given rate - no matter what battery(s) are connected.

Most of the time, for most of my camping, a single hybrid would do fine.   But, again, that is MY usage/style.

My two cents.  From a couple of visits to our local Batteries Plus.  I don't think you can find a more expensive battery supplier.  Check other local suppliers.  Safe Travels.

Thanks for the reply.
You have given me more info to consider.
I hope to be out boon docking for several days in a row including early spring and late fall in northern Michigan which may require the furnace during the day time.
I do have a 2000 watt inverter generator to be used as needed.

Adding onto furpod's comment: stick with deep cycle batteries.  They'll stand up to the discharge/recharge cycles much better; a hybrid battery really should be used in a situation where it's fairly constantly recharged to 100% (i.e. by an alternator in a vehicle).

Deep cycle batteries tend to all have around the same number of amp hours per pound.  So, decide how many amp hours you need first and then look to the weight, size, and price options that work for you.  I tend to use 30-40 amp hours per day in the spring/fall when the furnace is going.

One thought about dry camping with lead-acid batteries and a generator:  Your goal is to not let your batteries drop below 50%.  Lead-acid batteries bulk charge to 80% of capacity fairly quickly (1-2 hours) after which they charge exponentially slower (8-10 hours).  Ideally, when dry camping, stick to that sweet spot - allowing your batteries to drop no lower than 50% and then charge to 80%.  This minimizes your run time and keeps your batteries in good condition.  At the end of your trip, make sure to charge to 100%.

For me, with a pair of group 24 deep cycle batteries, this means I charge for 1.5 hours every other day in the summer, and every day in the spring/autumn when I'm running the furnace.
