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.

The 9V alkaline cell that backs up my alarm clock is going on 5 or 10 years now.

Jim:
There are other batteries but none that will last ten years and give you 3
volts. I understand you not wanting to pay the surcharge UPS wants for a
lithium battery transport but there is a simple solution. Buy the CR2032
battery holder from Digikey and have it shipped first class mail. Then head
into town, Anchorage if you must, and head for a drugstore for the CR2032.
Ten years from now when you replace it again you won't have to even heat up
the soldering iron.
