Charge time for NiMH AA batteries in MH-C204F charger

This graph shows the charging time to reach 1.4V for NiMH AA and AAA batteries in a MAHA MH-C204F charger. At this point the inidicator lights on the charger will still be red. However, if you continue charging until the lights turn green, the highter resulting voltage will rapidly drop to 1.4V. The lowest voltages on the left correspond to over 100 photographs taken with a Nikon Coolpix 990 digital camera and recorded on a Lexar 128MB 8X CF card. There was a mix of flash and monitor use.
Get a very small digital voltmeter from Radio Shack, Model: 22-802 for about $19.99
