no-hoper says in #9998:
"Original 3V lithium battery from ULB.18 month overdue..."
lamajoat is right. My "O" level Physics tells me that just because the battery, on open circuit, shows a voltage, it does not mean that it will deliver a current when asked to do so.
It is a disgrace that CVR and FDRs are not equipped with batteries that will perform for a year. Designed for "transponder mode", even the existing battery would give a phenomenal life.
