the reading you need is a voltage drop of 5 mv per cell for nimh and 10 mv per cell for nicad. Regular dvm may not be precise enough to detect it.

Temp increase or max temp is also a reading you can use.

I'd strongly suggest getting a peak charger, they come pretty cheap these days. Without that, it is difficult to get a correct charge - you will likely either undercharge, resulting in poor performance, or overcharge, eventually leading to damage of the battery.
