This battery lasts the life of the router under the operating environmental conditions specified for the router, and is not field-replaceable.
But who determines its lifespan?
Knowing there is a battery set to fail and I can’t simply replace it makes me physically uncomfortable. Enough so that I’d rather it not have RTC.
Thanks Cisco.
Oh, re-soldering to the board? Absolutely. Re-soldering to the battery? Nah.
Yeah. The battery could just get some pressure and a little piece of tape to hold it in place.
