Li-ion chargers aren't as commercially widespread as NiMH chargers. Precautions must be taken to avoid overheating cells and they should be monitored while charging. Some people only charge li-ion cells in their fireplace or in a steel bucket! For tips on safely using Li-ion cells refer to [http://www.candlepowerforums.com/vb/showthread.php?t=235164 this post]. The important thing for li-ion chargers is to correctly stop charging when the battery voltage reaches 4.2 volts (for a typical 3.7 volt cell) and not to charge at a rate exceeding the capacity of the cell (e.g. "1C" for an 800 mAh battery is 800 mA). See [http://batteryuniversity.com/learn/article/charging_lithium_ion_batteries this article] from Battery University for information about properly charging li-ion cells. A good charger will slow the charge rate as the battery gets closer to being fully charged.
