I miss the days when you could buy a battery that was serviceable.
A heavy glass plate case with bolt on top and removable plates.
They would last forever as long as one was willing to do a bit of
service work.

I'm afraid I'm not old enough to have ever seen one of those. When
were they used?



Gee,who wants to mess around with sulfuric acid and lead paste?


It`s only a few years ago when I worked in an entertainment venue where
all the emergency lighting was powered by huge glass lead acids, each
about 12" high and wide. there was probably 30 or so cells all connected
together by exposed lead bars bolted to the terminals, you had to watch
where you layed down anything conducting like a spanner!. The charger
was in a filing cabinet sized enclosure with a huge transformer,
selenium plate rectifiers and wobbly meters on the front ;o)
