 Don't take me wrong Johnny, not having a go at yea, been punching  buttons for a while, and a bit over it, but I have to say I've experienced a few battos that've been down to small volts, and come good with a 'kick'...not to say it's in their favour, but they hang in there.......!!!

   Good and well, but did Gel/AGM exist when 'Our' bikes were modern......? Not disputing what you say, just sayin'....

No of course they didn't have those types back then, they had to live with what was available, if you take care of a wet battery and check the voltage and top the charge up regularly it can last for a long time. It's when the voltage goes down that this type of battery takes more punish.
Because of the thinner lead plates they also normally have a shorter life span.

Well, if you grab it when there still is some lead left you can sometimes charge it up to the right Voltage and it will stay there.
The capacity might have taken a serious beating though.

When I think about it there is actually more things that happens to a over discharged lead-acid battery, there are build-ups of oxide or sulphate on the lead plates that stops the travel of the electrons...wherever they are going...

For our bikes, "wet" are no good, they are constructed for short bursts of high Amperage, like a starter motor

Was there much else about when our bikes were  new and legs were the norm for starting?
Yes I get the short burst high amp bit however I think it's more the case that batteries used to be more reliably built as far percentage of individual battery failures goes but over all decent batteries last much longer now, thinking of my 6 year old Focus still on original battery whereas in the sixties I seem to recall fitting a new battery was a regular thing every couple of years.
First house I remember living in (up to 7 years old) had no electricity, Dad built a "Wireless" housed in a wood vegetable box, it ran on two glass Accumulators (remember them) used them until they where flat then took them into Dumfries to get swapped with charged ones
Later in life during the cold war years I was a volunteer with the Royal Observer Corps, we had underground observation posts lit by NiFe batteries (Nickel Ferrous), these held the full charge for longer periods then went down fast.
So the technology may have changed and left out on a limb a bit

I should start by saying that English it not my first language...I should have said "not as good" instead of "no good" :-)

Glass Accumulators I have actually never heard of, wonder which chemistry they use?
NiFe I have heard about, If I remember the facts right they are very heavy and are still used today in solar plants for power backup.

What I use in my electric vechicles is LiFePo4, a type of Lithium-Ion battery, about half the weight and more than double the energy content compared to a Lead-Acid battery of the same physical size.
Have thought about using these in my BSA, but they are quite expensive and very sensitive to overcharge and over discharge.
Must have electronics that keep them (warnings at low and shunting at high) between 2.5 and 3.8V/cell at all times.

Sorry if I get a bit technical, batteries is another hobby of mine. ;-)

 Johnny, I'll keep in mind that Ingleesh is not your native tongue, I hadn't noticed- although I have noted that most people who speak it a a second lingo, are usually better at it than the rest of us.....self included

 I was speaking with a solar guy yesterday about many things, one being batteries, and I'm sure he mentioned the Nickle-Iron something...I don't think I'd heard of them before, and he did show me some lithium ones...

 I'd like to use a good quality battery, just need to track one down, but reluctant to do that until I'm certain my charge system is ok, maybe upset the neighbours today *smile* if I drag myself away from here...- many things to tend to and work has been interfering with my life..... *conf*

Now that is a cracking song. One long bass solo really. Would that have been Lemmy?

if the photo goes with the track - yep
Hawkwind got through a lot of folks, Lemmy got chucked out for drug abuse it's said (that's was quite an achievement in that band)

No way- silly enough already- and drinks are for washing things down(double dip maybe?), people pay big money to be like me *smile*

 That's funny B-Bill maybe somethings watching you- what's that over your left shoulder.. *????*

 Anyway this is a battery story, I figured an accumulator may be some kind of capacitor, and it kind of can be;-

 But it sounds what Bill has in mind is just a fancy name for portable battery ?

Exactly and basically the same as a lead acid battery in a glass case, car batteries possibly morphed from accumulators  to an accumulator in the familiar Bakeliteish or whatever it is 
case, glass being too fragile for the task

I've heard it referred to as 'rubber cases', even the guy at the battery shop yesterday said it I think- probably a rubber compound?? Bakelite might be a bit brittle. I guess a few of the other guys'll know..??
