I'm looking to get this PLB but was wondering what others have done about its purchase. The battery should be replaced at the earlier of 6 years from the date of manufacture or 5 years from the date of purchase. This model has been around since 2011.
The battery replacement in this unit is very expensive so most people would opt to buy a new unit rather than replace the battery.
How would I know when I order it from a retailer that it wasn't manufactured in 2011 and has been sitting around in the warehouse since then? In that case, I would have to replace the battery in 2017 and would lose 2 years of use.
