Best deep cycle ?

Mena... don't argue with the Financial Analyst in me. It's about residual discretionary income left after buying batteries that leave you with more discretionary spending money for stuff like new fly reels or rods, or fly tying material, or whatever you choose to spend the extra savings on, or will to your family or kids.

$180 of batteries amortized over 8 or 9 years or more is a little more than $20/year or just under $2 a month in battery expense.


Oh, and I do monitor, buy and sell stock from my travel trailer. Can't afford to miss a trade or a good buy while bottom fishing, or a good sell. Need electricity to do that. Whether it comes from the sun, the gennie or batteries, gotta have it.

The cost of my MH absolutely DWARFS the cost of my battery bank. If I wanted to make money on vacations, I would've bought a condo in Hawaii and rented it out and made sure the rent paid for the condo AND the vacation AND put money in my pocket. My RV and everything associated with it is a 100% total loss. Battery type, size and cost is irrelevant. If your RV isn't a big financial minus, cool, but mine sure a hell is.

Lets say you needed 100Ah usable capacity from your batteries, and your main charging system was from the vehicles alternator. Now with conventional deep cycle batteries because you would only have 25% of your battery bank usable you would need 400Ah of battery bank, now there are a few ways you could do this, but the least expensive way would be four x 225Ah 6 volt Trojan batteries at a cost of $1,120. Now with AGM batteries you could have just two x 100Ah giving you 200Ah total, so there is your 100 Ah with heaps in reserve and an easy life for the batteries, so only 2 batteries, at a cost of $710 all up, or better still you could use a single 200Ah battery for a cost of $695.00. - See more at: http://www.fridge-and-solar.net/agm.htm#sthash.lE3bx5yy.dpuf

Your assumptions about use and price is definitely flawed. The comparison is not accurate. I choose not to explain it, I'm pretty sure everyone knows.

X2.... He is wrong on so many points, that I wouldn't know where to start... And I really don't feel like writing that much.

Ya, understood. Reminds me of a line in a Clint Eastwood movie, "He's a legend in his own mind..."

Back in the lab we have a name we use, it's "Jack*ss" (when they call you names and can't debate your claims, you've won the argument). :p

$89 each, or $178 for 225Ah in 12V. If that's not the most cost effective system, someone please edumacate me on a better value, over say 8 years.

Better value and RVing is for the deluded. There is no VALUE in RVing. The financial loss is 100%. It's just for fun. I could see a value argument if you made money from the RV (ex: you get more renters if you used AGMs vs FLAs and that increase made you some money) or used it for work.

I think we FLA users should get a Hydrogen Completion credit from the Gov't.. We're adding much needed hydrogen back into the atmosphere. It's a green thing....:B

DryCamper11 thanks for the great link with links.

As AGM purchase price drops in time I want to look at them as well. As more and more cars start going with AGM batteries that will help volume. It seems the old FLA battery technology after 100 years of usage is phasing out.

AGM Auto Usage

“We’re installing 6 million in AGM annual capacity for the U.S. market.

"Good for taxis, police vehicles, and high end luxury cars." Don't think that will be going in my cheap azz 21 foot travel trailer with a rubber roof. LA GC2's will fill the bill for me the next 8 years. And a PD9245C and 120w of 12 v solar with PWM charge controller.

There was an article how new cars are moving to AGM as OEM equipment.

There are a ton of good reasons to switch to AGM batteries. If you feel their advantages aren't of benefit to you, I'm in agreement. If you agree with me (and thousands of satisfied customers) that their new technology is beneficial, don't let it ruffle your feathers. You're more than welcome to stick with the old stuff that works for you - just don't be too quick to criticize those who appreciate functional quality.

I read that a flooded battery's #1 killer is vibration, the primary reason AGMs outlast flooded batteries and are the choice of the military. I also considered flooded batteries for my application, but my research provided so many good reasons why the extra money I paid was more than worth the price difference...and no more holes in my jeans or hydrometer readings! :)

There is a line I use when talking about OPTIMA batteries. (Which by the way are AGM)

If you are slamming over ruts, ditches, rocks, logs and such with your ATV,, OPTIMA may be a very good choice (Or waves with a wave runner).

But if you are driving your motor home or towing your trailer that way.. Batteries are NOT going to be your primary problem..

This applies here.. Yes, serious extreme vibration such as you get running over land mines, IEDs. and dodging shells... Yup, that might damage a flooded wet cell. Plus see true story below.

Driving down the highway in your 30 foot house... Not so much.

My mother worked for a military supplier of liquid storage and transport hardware (LOX tanks to be exact, they also use 'em for JET fuel).. This company makes some of the (if not THE) Best LOX tanks in the world, The military tests them by the B-52 method.. Load 'em up, fill 'em with a non-reactive gas (Helium) and drop 'em onto a concrete pad as you fly over.. If they don't leak, re-load and fly higher, And when you have just one tank still holding Helium.. That's who gets the bid.. The company my mother worked for.. Got a lot of bids.

Well a general shows up and asks if the Army was getting 2nds on hoses, cause the hoses supplied the military were not lasting as long as the identical hose at say Air Reduction Company. (NOTE the use of Identical). The quality control guy took the General out and handed him a hose, and a sledge hammer, The general chipped some concrete out of the floor of the warehouse by swinging the hose and banging the threaded end against it, He hammered on it hard as he could,, And then the QC guy took it over to a tank and hooked it up, No problem, No damage.

He then explained the difference between a well paid employee of ARCO who would get fired if he left the hose on the ground and ran over it with a jeep instead of putting it in the hooks provided on the tank.

And a basically unpaid private or airman who leaves it on the pavement and runs over it with the jeep.

How this applies to batteries.

I own the batteries in my house, I'm not going to toss 'em around like the aforementioned private.
