I have been using Tenergy RCR123A 3.0V (900mAh) Li-ion batteries (light blue with a narrow dark blue band at the negitive terminal end) with my SU-800 and SB-R200's for several years and have not had that problem. That said, I can't remember using them when the ambient temperature was 90 degrees or higher.
There are two types of Tenergy RCR123A\'s available. Mine look a little different that either one shown.
