[Elecraft] Another Battery Question

[George Cortez Jr]

Hi
So are you connecting the 14 volt supply to
The power connector or connecting in some other way (direct to the battery) 
Is there an easy way to boost the voltage on 
any of the astron power supplies?
I have several and can dedicate one to 
The k2

    Tom,
    
    If you can adjust your power supply to 14.0 volts, it should work a little 
    better.  I bought my K2 battery with the K2 in 1999 (S/N 462), and it still 
    is as good as new.  I also bought a Power Sonic 0.5 amp automatic charger, 
    and it floats the battery all the time.  It charges the battery at a 
    constant current until 14.4 volts is reached, then maintains a constant 
    voltage until the battery is charged as sensed by the current decreasing to 
    a small value, then floats the battery at about 13.8 volts.  My perception 
    is that if the battery is not  topped off at 14.4 volts it never is fully 
    charged, but it may reach full charge if floated at 13.8 volts 
    constantly.  It just takes longer to reach full charge.
