Measuring battery condition

Easiest way to measure battery level of charge?

Condition, capacity or state of charge?

Or when to start or stop the charging process?

Please post what you are experiencing and what your expectations are.
More details on the number of batteries and even the type of battery would help.

I have just used a voltmeter for a long time. Works fine.
