There are battery operated radios (gas-meters, SCADA...) that are able to
get many years out of a battery.  I'm guessing they usually sleep and wake
occasionally to transmit at full power using big capacitors.  I need .75A
for .5 seconds,  several times a day.  How do I go about ...

I have a General Radio 1650A Impedance Bridge.  It has two positions for

(reverse/ forward only) with a Single Pole Double Toggle/Throw (SPDT) relay.
Thanks for any advice.
