[Elecraft] K2 - Internal battery life?

[Stuart Rohre]

While I have not heard of any K2 gel cells leaking, it is known and I have 
seen Gel Cells similar in type and size, crack and leak in UPS systems. 
Especially if you have a 7 year old battery, I think I would pull it out, 
even if good, and get a fresh one in there to be safe.  You can always use 
the extra for a back up or for other radios externally.  Most users of UPS 
equipment replace batteries every 3 years, same for security hardware, (fire 
alarms, etc.) around the lab here at the univ.
