Interesting, not what one would expect from a major manufacturer. That said, I have found lithium batteries last a long long time in storage, obviously fresh would be better but from my experience most likely the older date code did not substantially shorten replacement period. The good news Snap-Hat Batteries are easy to source away from Keysight and most likely later date codes.

So 25 years old. The voltage were 2.8 V and 2.5V respectively. They unit never lost cal data. I replaced them by two batteries from Ebay that were manufactured on 2015. I asked Keysight for the date of the batteries they sell, they could not tell me just said they will sell "fresh ones". Even if my Agilent unit was built the first Agiletn year 1999 that meant they put 5 years old batteries, but my unit is most likely arround 2005. So that means Keysight put older batteries. Anyone has experience ordering batteries for Keysight? How long do these batteries last on the shelves?. My 2015 batteries how long can they last aprox? _______________________________________________ volt-nuts mailing list -- [email protected] To unsubscribe, go to http://lists.febo.com/mailman/listinfo/volt-nuts_lists.febo.com and follow the instructions there. _______________________________________________ volt-nuts mailing list -- [email protected] To unsubscribe, go to http://lists.febo.com/mailman/listinfo/volt-nuts_lists.febo.com and follow the instructions there.
