One of the major problems with battery life is the fact that a (say) 12 volt battery comprises of six individual cells and is charged and discharged on the basis of the six being in perfect harmony, they are all manufactured so they are all different
Imagine a family, one big man, a petite female and three children of different ages and sizes and they all eat exactly the same size meal which is designed for the smallest member
A battery charging system will usually charge at the rate for the weakest cell
In simple terms 8000 individual cells will be recognized by the changing system by the requirements of the weakest cell, most batteries will fail due to only one cell failing
Submarine batteries These are apparently six volt sets
View attachment 1692745With a car battery which has failed you can sometimes get the car started if you literally cut the poor cell out and run it as a ten volt battery
for over a hundred years a single cell/small cell group has been removableNO -- each cell has been grouped together with others to form a complete "battery" so it has been necessary to replace the complete battery as individual cells are built together
In early Home lighting sets they did use individual cells but that is rare
Therefore when you have 8000 separate calls, they are grouped also into individual batteries and treated as a group rather than individual cells it has been impossible to isolate one individual cell, The complexity of treating 8000 cells individually has in practical terms been impossible
