The output of the original battery SLB 11A is 3.8 Volt. I found several cheap replacement batteries, however some of them are "only" 3.7 Volt. Anyone using 3.7 Volt batteries and encountering problems because of this? Or does the EX1 work just fine with 0.1 Volt less?
It's a non-issue. The capacity in mAh is what's important. The camera will shut down when the voltage drops too low and that should be well below 3.7 volts. FWIW, every battery ever made can have different voltage ratings. The no load voltage is always higher, and the load used by the battery manufacturer is what determine the voltage rating. A battery tested at a 150ma load will have a higher voltage rating than one tested at a 750ma load. They also will produce different mAh ratings. A really cheap battery might have only 80% of the Li-Ion content inside the battery shell. This will result in a lower mAh capacity rating (if the company is honest) and the battery life will be 80% of Samsung's own battery. But the cheapy should also weigh less if you bother to weigh it, but it will have the same 3.7 or 3.8 voltage rating, just like all alkaline, manganese and carbon/zinc batteries are usually rated at 1.5 volts, whether they're D, C, AA or AAA cells.
