I'm specifically asking about a Fuji NP-T125 battery, but this may apply to others as well.

The NP-T125 is for the Fuji GFX50s & GFX100. I have several original batteries plus 8-10 Watson "equivalent" batteries. I've never noticed a problem with the Watsons with the Fuji before but just noticed the OUTPUT VOLTAGE is only 10.8 VDC for the Watson versus 12.6 VDC on the Fuji original batteries. I checked specs on the Bescor also and their output was also only 10.8 VDC.

Does the voltage difference make any actual difference in performance?

I would stick with the 12.5V batteries since that is what the camera was designed for. See a PM I’ll send you.

Thanks E.J.

Any idea WHY Watson and others don't engineer their batteries to output 12.6 VDC instead of 10.5 VDC?

Sent you a reply to your PM too.

My guess is that they are using a generic battery module for all of their third party batteries and just putting them in different form factor batteries. It will work but you have a lot less margin for error in case of power fluctuations or long term rechargability since you are starting with a lower base voltage to begin with.
