Yes this is true for wet cells. The Gell cells seem to have far more
longevity. Perhaps the flaking is held back in place by the gell. I do
know they take more care, but if that care is taken as I am using very
elderly batteries (gell) they last for well, years and soon here decades.
However the voltage and amps charging are critical for gell cell battery
longevity. I have many recycled alarm batteries (brick size) that run my
little portable radio sets. One has passed ten years and going strong.
As for solar power, well I tried wind, but that proved to be short lived.
In the sheltered valley, not enough wind. On a sunny day I get six amps,
on a cloudy day up to an amp (often less). Unless the regulators hold back
at max voltage allowed.
If all fails the mains chargers can be switched on. On peak (NOW) 0.28 UKP
per Kilowatt hour or timed off peak (01:00 to 08:00 depends on tarriff)
0.055 UKP per kilowatt hour. If the weather is too cloudy I use off peak
first to save cash.

I thought the distinction of the difference was blurred nowadays. I did
hear of secondary fuel cells. Perhaps the concept was not viable? Pehaps a
combi fuel/elecrolosis cells in combination using a gas storage system.
However it would be an exotic type of device not for general use as it
would be expensive and eye watering costs to run.

If memory serves correctly, an experiment was done with rats in a maze.
There was limited food and water. At a certian point war broke out as the
poulation rose for the depleted resources. I note from history whole
civilisations have ceased to exist due to food or water or both reaching
colapse in supply. The awlful reality is if you do not have and will die
without, then war is a valid option either way you are dead. Such is the
way the world is. Starve or fight to survive. Have you got the bunker
ready?
