[Elecraft] Alternative battery for K2?

[Don Wilhelm]

The charging scheme for the K2 internal battery is based on using an SLA 
battery.  If the battery is changed to another battery chemistry, the 
charging circuit would have to be modified to match the charging 
requirements of the replacement battery type.
Since Lithium batteries require very special charging techniques, this 
is a matter that is not to be taken lightly.
A simple replacement of the K2 SLA battery with another battery 
chemistry would have to be a redesign of the charging mechanism.
