Depends on battery type and which things you want the most: battery life, runtime or speed.

Here are some tips:

Schumacher Mi5 - Sanwa MT-4 / RX-462 / KO Propo PDS-2123 - Nosram 5600 X-treme Saddle Pack - LRP SPX Zero/X12 17,5 - Nosram Stealth Touch Evolution - MAAS SPS 9250

When using NICad or NIMH battery's do not go below 0.85V per Cell or you will distroy them.
In general 0.9 V per cell will do, so for a 6Cell pack this is 0.9Vx6=5.4V.

If you use higher voltage settings like 1V per cell this will not make them compleet emty and you can get memory effects with the NICAD's.

Greatz Whacky.

Voltage Threshold: A user selectable feature used in most of the newer chargers whereby the user can set the amount of voltage change that is necessary in order for the charger to detect a "Peak" in a battery pack. As cells charge, the pack voltage will increase until fully charged. At this time, the voltage on the pack will start to drop. When the voltage drops by the amount set in the Voltage Threshold setting, the charger detects this as a "Peak" and charging is terminated. This is an especially useful feature to prevent overcharging cells. The higher the Voltage Threshold setting is, the hotter the cells get. High cell temperature is detrimental to the overall longevity of the battery pack. In general, NiCd packs can charge and peak normally using a 12mV/cell setting, while NiMH packs (3000mAh sub C's) require a much lower setting of 4mV/cell.

telengard gave some good places to start. basically with nimh just adjust it for how hot your packs get, if they coming off hot not warm then lower it a mv.
