I downloaded the manual before I purchased the charger and remote, just to make sure it would do what I wanted.
The manual says "Note; All remote modes/functions are identical to those described by using the on-charger controls"
By pressing the setup/enter button for 5 secones you should be able to select battery
type, but included with the remote was an addendum that states, pushing setup/enter for 3 seconds putts you in the language mode. (A much more important feature to be able to choose Languages over battery type from the remote LOL. )
You should also be able to scroll to battery type and change it with the up down arrows, but when at battery type the arrow keys won't work.
I suggested a program update and they told me it was not possible to make the remote do what the manual says it will do. They said they were aware and talked about it, yet after all the years this charger has been out, they still haven't changed the false wording in the manual.
When I told them I was extremely disappointed and would be writing a bad review, they offered to send me pair of Pronautic Binoculars to help me see things their way.
