I use AW protected 17670 in mine. Not sure about the runtime as I am still on the first charge. The output is the same as primaries but it will blink twice every ten seconds.
Glas4d,
I just received my Gladius black HAIII S/N 177xx a couple of days ago from [email protected]. Before I bought the light I PM Todd and he told me it is the latest stock. The black HAIII has a very nice matte finish.
David,
This is what Kevin of Amicom Inc. wrote me:
RCR123A 3.0 is safe for AmiLIte.
I don't recommend RCR123A 3.6 V, but it can be used in AmiLite.
Please check outer diameter of RCR123A.
Inner diameter of AmiLite battery tube is 16.8 mm.
Ron.
