There is very little literature on battery charging, of when a charging
device might switch from constant current to constant voltage at
different initial charging currents.


My car battery charger, bought second-hand forty years ago for £5, has
just packed up. Can anyone recommend a suitable replacement? Doesn't
have to be portable, just plug into the mains and recharge a flat car or
lawnmower battery. Preferably for the same sort of price I paid for the
last one ...
