Canon USA Warns On Lithium Batteries In Speedlites


Canon Speedlite 600 EX-RT

Canon USA has issued a warning against using AA Lithium batteries in any Speedlite or Macrolite products and compact battery packs, including those listed below because certain AA lithium batteries may become extremely hot during usage.

I must say this is rather bizarre because I have been using Lithium batteries in my Canon Speedlites for years and never encountered any problem. It must be on the advice of their lawyers to cover all the bases, just in case of some very rare occurrence.
