[Elecraft] K2 - Battery needs CPR

[Don Wilhelm]

Tom,

Sorry, but there is no good cure for your exhausted SLA battery.  They 
do have a limited lifetime, but if left discharged for a significant 
length of time, there is no bringing them back.  I would guess that your 
efforts to bring it back to life would cost you more time and energy 
than the cost of a new battery - but then each has his own criteria for 
the worth of his time - YMMV.

73,
