Hello 1HI4X,
SureFire has a couple of different chargers. Their original chargers had a tendency to cook the battery packs. If you have one of these, it will cook both NiCd and NiMh packs.
They finally came out with a revised charger that utilizes a timed bulk charge, has a top off charge, then drops to a low trickle charge. This one is a lot better. If you take the charger apart, these newer chargers have a place for a switch to select between NiCd and NiMh. One of my early models actually had the switch, but when it died, it was replaced with one that did not have the switch.
You can tell which charger you have by watching to see if the green LED goes into a blinking mode at the end of the charge. Main charge has a red LED, then it goes to the top off charge with a steady green LED, then it goes to the trickle charge with a blinking green LED.
You can charge NiMh cells with a NiCd charger, but because NiCd chemistry looks for a larger -dv value, you end up overcharging the NiMh cells and they won't last as long. The new style charger may already be set up for NiMh charging. My charger with the switch had the switch in the NiMh position.
The other problem comes from the timed bulk charge. It is set up for a NiCd battery of less capacity than most replacement NiMh packs. This means that if you try to charge a larger capacity pack, it will not get fully charged.
The work around for this is to double charge.
To answer your question, yes, but with qualifications.
