Yeeeeeehaaaa,
Go the battle of the sparky's,
im still reading, but I wouldn't take bets on the outcome. If I want to know if a small battery has power, I stick my tongue on it, if I want to know if 240 volts are on it, multimeter and a lot of common sense.
You two can debate the rest of the details, but im still learning
No offence intended.
Um yeh that is what I thaught.Originally Posted by TheRealAndy
The lifeline batteries appear to be a stereo typical AGM battery with glass mat between the cells and what appears to be an unthickened electrolite.
DEKA, make both "gell & AGM" batteries & their documents also seem to support gelled or runny with glass mat electrolite being the difference
Sonnenschein well known as a gell battery manufacturer for a very long time and make of no other technology say that they use a fibreglass mat inbetween their plates to further immobilise their gell.
The brands escape me but, I read some making a big deal of gelling the electrolite in their "AGM" batteries so they can be more reliably be operated other than upright.
perhaps the some of AGM people just thicken the electrolite a little.
The matter is further complicated by sealed battery manufacturers using glass mat between their plates and or gelled electrolite and claiming neither GEL nor AGM.
Or is it a case of AGM being a recently invented marketing term for what we used to call "starved electrolite".... But GEL is also a starved electrolite...perhaps they needed a term to differenciate.
It was so much easier when things were straight forward.
Indeed the laws of phisics havn't changed......who said they have?
But the mongrels keep changing the processes involved, and nothing is as simple as it once was.
When I was an apprentice a almost all were wet cell batteries and they all behaved pretty much the same.
GELL and other sealed batteries were new and relativly expensive, the gates company had just braught out a battery "rolled up like a carpet" and we never heard of AGM.
Back then a multi stage charger was a switch operated by an apprentice with a watch and a notebook ( ya know paper with spiral at the top data enrty with a pencil).
Now they are all fiddling with the chemistry and they are all using a blend of technologies.
All publishing differing specs, claiming different advantages in performance or to have illiminated this or that inherant problem with a particular technology.
And of course one or two making claims that simply can not be trusted.
Gell batteries were known for not tolerating high charge or discharge rates..but sonnenschein have a range that has very high charge & discharge rates.
One AGM manufacturer claims some sort of self charge current regulating property
Several claim to have completely illiminated the thermal runaway problem in AGM.
Maybe not changing the laws of physics, but fiddling with the process.
cheers
Its the details, those little details, that make the difference.
Oh come on Andy. Be a sport.
Your turn....
I wouldn't know about this stuff. I haven't had the need to charge a battery in yonks...and don't want to.
I intend on living for-ever....so far so good
Nah mate, not buying into it. I said my piece.Oh come on Andy. Be a sport.
Your turn....
I wouldn't know about this stuff. I haven't had the need to charge a battery in yonks...and don't want to.
My early apprentice and electronic design years were spend doing remote weather instrumentation. All were 6 or 12V installs, most was solar powered, but some had mains power. We mainly used gel, however depending on size of the install we would also used AGM or flooded lead acid. Flooded lead acid was by far the most reliable, and pretty much never had batteries replaced. I got to design a few chargers, so I think I am qualified to comment. I spent most of my apprentice years building, repairing and installing these systems, so I think I am qualified to comment on that part too.
This should complicate things and explain where the cheap AGM batteries came from. I knew the history when I bough mine.

Andy,
If you still want to borrow my charger, no probs.
Maturity is not when we start speaking BIG things,it is when we start understanding small things
So the suposed Gell battery contained a small% of "Silicon dioxide" which I understand is the thickening agent used to gell electrolites, but not enough to make it a GELL battery.
I suspect they were incorrectly labled batteries and they seem to be slightly gelling their electrolite in their AGM batteries...or are they using glass mat in their gell batteries and there was a failure in the preparation off the gel?
come on andy out with it......what don't you agree with.
cheers
Its the details, those little details, that make the difference.
And again I notice that non consensus is happening.
Why is finga not in on this one?
Why has Oldboot got so much to say?
If a battery is flat why can't you just put a charger on and let it charge up?
It cannot be that hard can it?
I think I'm very lucky been a girl and not knowing anything at all.
But by just reading I've learned a lot and it is not about batteries or battery chargers.
You males amuse me and some words I read here some time ago come to mind
Arguing with an idiot only proves there is two.
It seems the lesser idiots have had enough.
It must be about time the bigger idiot known as finga step in and take over from TheRealAndy.
Or perhaps we just get Phil to lock the thread before we all start abusing you for calling us idiots.
Oi. You can't call me an idiot you frog leg and snail munching witch.
Don't worry Andy. She's a friend of the cook's and she loves taking the micky out of me.
Wait until I see her again.
I intend on living for-ever....so far so good
FrogBat who brung you?
If you don't like it don't bother reading.
