[There seem to be two main classes of domestic battery chargers](https://en.wikipedia.org/wiki/Battery_charger#Intelligent_chargers) - "intelligent" chargers which charge batteries individually, until some measurement(s) of the batteries determine that charging should cease, and dumb chargers which charge all batteries at the same rate.

These terms are marketing-speak and have no real formal definition. However, is it possible to approximate the functionality of an intelligent charger, simply by charging one battery at a time?

I am mostly interested in domestic batteries with NiMH chemistry.
