I finally have found and installed my 9V battery charger again. Almost
all of my Organiser IIs are out of juice so I am going to retun them to
life.
The Organiser II uses the brick-shaped 9V batteries. IT accepts both alkaline ones and the modern 8.4V rechargeables. I use the rechargeable ones but the problem is the charger. I was only to find a bulky device which is impractical to store or transport. Thus I have only one (at home) unlike the AAA/AA chargers which I have in several versions strategically located in all places (home, works,...) where I may need to charge something.
And that only 9V charger was carefully packed and stored during
construction works at home. So carefully so I was only to find it just
now (after some 2 months). Obviously, only one battery (the spare one
which was not inserted in any Psion) survived with some usable level of
charge :-(
