Thanks all. I ended up ordering a Wasabi battery, and Wasabi dual charger for NP-W235 batteries. It came to $36.98 free shipping. I have used their chargers before, but never used their batteries, but the consensus seems to be their batteries are fine. If the charge does not last quite as long (this will be a spare battery), that is OK. As an 84 year old Amateur, I have a limited number of shots in me! ;-)
Thanks again

P.S. To Jonathan: I just sold my Fuji GFX 50R and pre-ordered the Fuji GFX 50SII (To get the IBIS---a big deal for me). That camera comes with a battery BUT NO CHARGER. To cut the cost to the bare minimum, I guess, you need to put the battery in the camera, and charge it by plugging in the camera via a supplied cable. This is unsatisfactory to me. I may want to charge a battery and go out shooting at the same time. Thanks for your input
