PLB battery replacement?

I should say that Satellitephonestore was/is a authorized center for ACR; I found them by contacting ACR. So, if you have another brand, call your manufacturer.

So got the new battery, but with zero instructions.  This thread suggests that replacing the battery is complex, and that it may be better to have it professionally done.  If I were not subjected to constant scams, I might be more accepting of all this.  Will look around for someone local to install and test the battery, and continue to use the LG flip phone, which I carry anyway, and is good enough to seek help in most situations.  (It happens regularly with hikers in the White Mountains of NH.)  The PLB 1 appears to be fine now.  If it does need a replacement, that will depend on the cost.

Jerry; thank you much. Will try it when the current battery wears out.
