. Some models can be replaced by either NiCD, NiMH, or Li-Ion batteries. If this is the case, you may notice that the NiCD and NiMH batteries cost significantly less than their Li-Ion counterparts. Before you jump for the cheapest option, however, you should know that these batteries will have lower runtimes and lower overall life spans than lithium batteries.
