my sticker from NOAA came and when i was putting it on I see the battery should be replaced this summer.that info is hidden under
the peel back label on the plb so this was news to me.
a check on the web and its $100 new and $35 refurbished.
I have never done a battery check as I don't like to turn it on.
I always assume they err on the side of it being better than the due date??
