Hi,
I was looking over the two Sea & Sea YS-90DX strobes I have purchased over the last couple of months and noticed a change in one of the caution labels between the two (one of the strobes I bought used, the other I purchased new from Japan). The caution label on the new strobe read: "Use only manganese, Ni-CD, alkaline, lithium, or Ni-MH batteries. Other batteries may emit hydrogen gas and possibly cause an explosion." The used strobe I purchased does not list Ni-MH batteries as being acceptable. The manual that came with the new strobe does not make any specific reference to the types of batteries to use.
Before noticing this discrepancy between the labels, I had done much research on people's own experiences (at the time I thought Ni-MH batteries were not recommended for use in Sea & Sea strobes) and determined that I would throw caution to the wind and use Ni-MH batteries for the convenience and greater capacity.
Anyway, has anyone noticed this change? I am assuming that Sea & Sea now views the use of Ni-MH batteries as acceptable, albeit possibly not at 2000 mah.
