Thread: Epson PX-8 battery options

  1. #11


    The main battery connector appears to be a JST XH series, 2.54mm (0.1 inch). That is what I bought from ebay and I "think" they fit correctly.

    The aux battery should keep the memory contents when the power is off. It isn't intended to run the computer in the absence of the main battery.

    It did switch from fast charging to trickle charging so that is good. I found that 7V for a fixed voltage is probably decent. 6V is too little and does not charge fast. 7.5V is where the internal zener breaksdown so you don't want higher than that. I'm going to start with a 7V adapter to charge it.
