Battery replacement of Preston HU1

Recommended Posts

Hello guys! I have Preston wireless follow focus the 1st generation (HU1, MDR1, DM1).

The problem is battery for HU1. the big square shape old battery. I only have 2 of them and it is hard to find more. So what I thought is replace it to EP or NP battery. 

Do you guys think is it possible? if it is possible or know who already did this process, please share the information !!!!

Also, if you know repair shop that does this kind of work, let me know please!!
