[SOLVED] Will batteries charge serially at greater than their nominal voltage

Can batteries serially attached be recharged by a voltage source which is the total combined series battery voltage? I ask because total series voltage exceeds anyone of the batteries nominal voltage rating.

Another words, will this setup cause batteries to leak/explode:

Hi,

Mind:
A 12V car battery is made of 6 x 2V batteries in series.
It works and the battery can be charged.

The drawback:
The weakest of the 6 (or any other number) cells determines the livetime of the whole battery.

If you build this on your own you need to ensure that all cells are in equal condition.
The weakest cell will get
* the highest charging voltage --> overvoltage is reducung the cell lifetime
* the lowest discharge voltage -> undervoltageis reducing the cell lifetime, too.
The solution for this is a more intilligent batterycircuit with charge balancing.
With this the healthiest cells support the weakest cells ... resulting in higher battery useable charge and higher battery lifetime.

You say "voltage source"
A true voltage source is no good battery charging circuit. Each battery chemistry needs it's own charging concept. Like CICU.
Read though: https://batteryuniversity.com

First point, correct your schematic. No battery is charged by an unlimited voltage source, neither single nor multiple cells.

I'm not sure which battery type you imagine for "3V"? Curiously you have drawn multi cell battery symbols, even with different cell count…

In other words, I would appreciate a clear and consistent question.

Generally there's a problem with charging in series circuit if the individual cells aren't guaranteed to have exactly the same capacity and initial state of charge. With lead-acid batteries, it's usual to charge multiple cells in series. Li-Ion batteries in contrast need balancing circuits, they are built-in with any battery on the market, e.g. notebook batteries.
