If you’re only occasionally crossing Lake Ontario, you can rent an EPIRB by the week from BoatUS:

The vast majority of PLB’s and EPIRBs (esp ACR) have batteries that must be replaced every 5 years even if self-test sequence shows battery is good (battery exp label is on each unit). ACR does not sell EPIRB replacement batteries to the public, you must send in your unit to an ACR Authorized Battery Replacement Center. They don’t just replace it, also the seals, O-rings, function test, antenna test etc which is usually over $250 w shipping. And ACR will not replace a battery in a unit discontinued 10 years ago or over 12 years old.

The good news is that if you ever set off your ACR device and get saved, they’ll replace your unit for free (I bet ACR would give this fellow another one even if his receipt is on the bottom with his boat).
Rather than replace the battery again on my old ACR, , I bought a new ACR GlobalFix V4 EPIRB in 2019 for $399 on sale with a 10 year battery (“Battery Expiry: 07/2029”). This could be cheaper in the long run. Check the battery exp date on the unit before buying to be sure.
Although you can find non-OEM batteries that claim to be the same on EBAY, I wouldn’t advise going there for life-saving equipment.
This fellow would be a goner had he chosen a PLB rather than EPIRB, because no PLB can self activate when it hits the water, it won’t float upright with the antenna pointing upward (many won’t float at all), and he didn’t have time for the 3-step process to activate a PLB. I can’t find the reference right now, but I have previously read that an EPIRB activation requires a COPAS-SARSAT SAR launch, but a PLB (or your Garmin Inreach satellite text unit) does not.
Happy shopping!
