The Canon Speedlite 600EX-RT uses a matched set of standard AA cells. Rechargeable AA NiMH is the suitable rechargeable format. Do not use 14500 lithium-ion cells, and do not mix chemistries, brands, capacities or charged states. These real AA NiMH lines are compared by labeled capacity and low-self-discharge positioning; no recycle-time promise is made.
