Since we are having to spend a majority of our day in lock down during Covid-19 we needed to get all our entertainment devices up and running. Most devices where OK except for our Playstation PS4 Dual Shock Controllers where Sony in their wisdom (not) designed the controller with a non-replaceable li-ion battery. This battery (of course) no longer holds charge. While you can order aftermarket replacement batteries, we are Darwin and stock is non-existent and shipping is slow.
