[Elecraft] OT - Lithium memory batt

[Jim Wiley]

Hoping to take advantage of the knowledge base here.  Does anyone know 
of a battery suitable for memory backup (installed life =  5 years or 
more) that uses a chemistry other than lithium?  And hopefully comes in 
the "coin cell" configuration?  I need to order some CR2032 size, with 
solder tabs or PC pins, but the vendors tell me that lithium cells 
cannot be sent via the postal service, and I refuse to pay upwards of 
$25 shipping via UPS or FedEx for a $2.00 battery.
