What Makes a Deep Cycle Battery Different

Mrs Richards: "I paid for a room with a view !"
Basil: (pointing to the lovely view) "That is Torquay, Madam ."
Mrs Richards: "It's not good enough!"
Basil: "May I ask what you were expecting to see out of a Torquay hotel bedroom window ? Sydney Opera House, perhaps? the Hanging Gardens of Babylon? Herds of wildebeest sweeping majestically past?..."
Mrs Richards: "Don't be silly! I expect to be able to see the sea!"
Basil: "You can see the sea, it's over there between the land and the sky."
Mrs Richards: "I'm not satisfied. But I shall stay. But I expect a reduction."
Basil: "Why?! Because Krakatoa's not erupting at the moment ?"

Where I'm from.... The Southeastern US.... deep cycle marine batteries are actually cheaper than regular ones.

You forgot to mention the surface area

What an excellent video!

Old technology

The kid brain noises and animation are pathetic

But it's Ok to have a buckle on my belt though? Great video!

LiFePo4 batteries make these obsolete.

ALL BACK TO COST YET AGAIN, THE MONETARY SYSTEM MUST GO! put a joule thief circuit in the battery, jobs a good one doubles the life span.

yet lead is only worth a few cents a pound for scrap so in theory it should be less for manufacturing than copper.

recycle 1 pound of scrap bare bright copper and get maybe $3 buy 1 pound worth of bare copper wire at electrical store and pay maybe $20 or $30.


to keep the cost of battery manufacturing could be brought down by using sketchy labor practices maybe even making them in conflict regions (blood batteries anyone?)

I must be missing something because small capacity AGM batteries will die at the first attempt to deep cycle. Any ideas?

Correction - the paste for negative plates is gray initially. The positive plates are in fact red. The grid is nice, very accurate.

NOTE - seems to be correct later in video.

Because the new cars and trucks are now autostart/stop at lights manufactures are now putting AGM in from the factory, I have one in my truck, a good size AGM will set you back $200, I have always run deepcycle in my vehicles because I have Ham radios and need something that can go deep, even under the abuse of doing off road truck things LOL I have always gotten about 5 years out of a deepcycle, testing is still on going with AGM but at 4 years now

AGM also helps limit gassing. (charging always creates H2/O2. in a flooded cell, it's just gone. in AGM, much of it is held in the mat and can recombine.) I've not seen any gel cells in a very long time.

Excellent presentation.
Maybe batteries need a vibration absorbing base (Styrofoam?).

You van make a (cheap) phone for the price of a battery - which is more complex?

So BS to you theory.

it should be noted that AGM battery chargers are different as well

Fantastic video, but PLEASE pay attention to how loud the sound effects are versus the voice.
I crank up the volume to hear your soft spoken voice only to get blown away by the cash register and rewind sound effects.
Likewise be careful about layering music and voice as in some places the music muffles you out.
Besides audio this video is absolutely perfect.

Great video, thanks!!!!

I have a camper truck, with two deep cycle batteries and two starter batteries. I have been disappointed with the performance of my deep cycle batteries, trying to run a small microwave and toasters etc, they could not supply the amps to my inverter to run these units and to last, but using the whole battery bank, which is meant to be a no no mixing the two types, have no prob and the batteries last longer. Just goto monitor their discharge rate and never go below 50% discharge

Actually, lead is pretty cheap (ca. $2 per kilogram). The main reason why you don't want more lead is that it is heavy.

Yes but the Lithium manufacturing is far more complex, far more expensive materials, far deeper cycling, far better lifespan and basically the same retail price or even cheaper...

Lead just cannot sell anymore when "deep" means 20-50% rated capacity for a few years...

I was buying deep cycle batteries for my RV . They are abused. They would last about three years. Standard batteries last about two years. The standard batteries are less painful to buy and more useful to borrow by other vehicles in my stable.

I found this informative. But the music sucks in this

I ain't listenin (misspellings are deliberate) to 3 minutes of mind-numbing ads just to see a video put by this moron!

I actually learned some things from this informative vid (and i'm a retired ASE cert. dealer tech). My dad was a big believer in deep cycle batteries, especially for his boat.

This is the first time I've heard about an "active paste", moreover one that can flake off. In my area that language doesn't make sense, so I might search what that's about.
But I am curious as to its composition and any variants. Thanks for the informative video!

back in the 90's the gel filled batteries were just coming out, and i had a really good commercial battery salesman that explained all this to me, so i bought thousands of dollars of them for battery backup for a municipal first responder communication system (radios for police and fire). they worked out really well. this is a really good explanation though.

20 some years ago, the battery rep kind of pointed me into this, but was talking about high CCA batteries vs standard in a normal chemistry (so 850CCA vs 600CCA). To get the higher capacity required more and thinner plates, this video brought that discussion right back to me.
The rep was talking about how they had to produce the higher capacity batteries due to demand, but they had a lot more warranty comeback. For anything that went off-highway, we tried to steer the customers to the lower CCA battery just for durability. The equipment that took the industrial batteries we rarely had warranty comeback on.

This explains why so many motorcycle batteries dies after a season. The agm rubs the protective covering away, and when winter comes the battery corrodes away.

Great video but no explanation of how the slow discharge rate is achieved in a deep cycle battery? What about Life deep cycle?

Please learn the difference between energy and power.

Cyclon batteries for backup application in telecommunications and emergency lighting.
Cyclon batteies use pure lead -no calcium or antimony in the alloy, and Pb is 99.99% pure. They aren't manufactured in China, because they haven't the pure lead. Another feature is the starved electrolyte, in the sense there is only the quantity of H2SO4 necessary to complete the discharge reaction and not more. This limit the amount of lead sulphate which can form inside. The separator is a very thin glass mat under mechanical pressure.
These batteries are a dream to work with, especially the low internal resistance, the ability to operate in freezing conditions, and the very low self discharge. Their only problem, if neglected for long time, there will be no H2SO4 left inside, and you must use some unusual procedures to boot the battery again. I prefer a Cyclon - pure lead - over Li-Ion cells, as they don't die in hot weather or following a mechanical shock. Also, I had some cylindrical Lead-acid last for 25 years - you can't even dream that with Li-Ion; their high terminal voltage keeps them outside the thermodynamical window of stability; in Lead-acid batteries the oxygen over-potential keeps them very stable...

I went to a battery school many years ago put on by exide who is now enersys, and they had also commented that deep cycle batteries should not be left on a battery charger as they are designed to be charged and then cycled then rechaced, and that standard automotive batteries are designed to be charged all the time.

Nobody would ever recommend a deep cycle for a ups.. As most ups batteries are at 100% of their charge most of their life.

Is it possible to get a gel cyclon?

Your far out audio effects are like a suddenly screeching seagull in a serene ocean audio for sleep aid

You have not justified 3x the price.

You lost me at anode and cathode. I hope there's a simpler explanation why a deep cycle battery is more expensive. Will do a search. I hope there's a simpler explanation. Shorter video.

👍👍

Agm with a glass Matt seperator is the most expensive per ah battery for deep cycle batteries, followed by lead carbon then everything else

THANKS ALOT 👍, I NEVER KNEW THIS STUFF.

Who knew batteries are so mumbo,jumbo. Ok in your veiw sealed lead acid deep cycle OR gel cell deep cycle sealed for a monstrous mobility scooter

Yeah but the safe charge rates weren't mentioned. I don't think gel and AGM can take jigh charge rates.

So, what is the destructive function which ultimately plagues the tubular design?
Do they eventually bust open and drop their paste?

Also,
I think you've hinted at it by telling us about the shady practices of dishonest sellers but...
We now know that the construction of D.C.'s is slightly more robust... and that their manufacturers have begun using different shapes for their components, for DECADES by now, yet they still seem to require they cost heaps more to users because they haven't standardized the advanced (over older, simpler "flat grid-plated") designs to obsolete the antiquated "S.L.A." design.
However, are we supposed to take-away that, when it comes to the science of how they combine chemicals with materials in a reaction to avail electricity for use at their terminals... they do it, or "cycle," essentially the exact same way?
I was really expecting different chemicals or something.

Oooh oooh oooh... I have another question...
If it is the cycles which ultimately kills them, then why do they deteriorate when sitting on the shelves of sellers to the point of being merely core-worthy?
...if there is no occurrence of the destructive cycling process?

Can a Lead-Acid Battery be replaced with a AGM battery ?

What about lead graphite? What about lead crystal? New and effective and expensive batteries.

Shit videos
