Once the sulphation ceases to be "fresh" and begins the strong molecular bonding you refer to, is that when the capacity of the battery reduces with the result that the "fully charged" LED on a simpler charger illuminates prematurely?

Yes. The charger light says FULL but all that it is telling you is the part of the plate that can be charged has been charged.

The capacity of the battery is reduced progressively as the lead sulphate becomes compacted.

With that type of charger with red and green charging lights it is best to leave the charger on for 24 hours or more as it will actually, in some cases, put more electricity into the battery.


PS. I wrote out another post with some detail about PULSE charging but when I went to post it, it vanished. !!!!!!!--
