Default EPIRB Battery Replace vs New EPIRB

Ok so I got slack with my EPIRB battery.

The battery of my 10-year old ACR GlobalFix 2744 is expired. I can get it replaced by an authorized center for roughly $260.

A new ACR GlobalFix 406 Pro 2844 with rebate can be bought for $360.

Is there any functional difference between the old 2744 with a fresh battery and the newer 2844? Any difference in location accuracy, signal strength, transmission life, etc that would justify an additional $100 for a new EPIRB?

I don't know, but I would think that 10years in electronics is like 50years in humans. I would get the new one.

After the rebate it is only a $35 difference...for a brand new unit under warranty.

Sell your old one as is.

I would be surprised if ACR would replace a battery in your 10 year old unit. Being an ACR accredited service person up until 8 years ago, I refused a 2nd battery replacement for 10 to 15 year period as the EPIRB components life expectancy was exceeded. The biggest problem was the instability of the transmitter to stay within the frequency tolerance of the satellites. Would suggest you trade in or destroy but deregister it, then buy a new one. However it wouldn't hurt to keep it on board because the expiry date of the battery still gives 48 hours of distress signal bursts assuming testing was limited once a month. It can be used if need be as a back up, if only for the homing signal, but not as well as a new one.

No Question, Replace. I did last year and the newer model is much better.

Replace it. Put the old one on eBay.

I think I'd be a bit hesitant to recommend using what ACR is essentially calling an 'out of spec' product as even a backup for a bit of critical safety infrastructure. If indeed ACR thinks that the frequency control is going out on those transmitters, or anything else going wrong except perhaps somewhat decreased battery life, it would recommend recycling the thing (not selling to some poor sucker) and getting a new one.

With PLBs and EPIRBs being so cheap and better (internal GPS so you don't need to hook it to your chartplotter) it's hard to recommend cheaping out on something that costs perhaps a weekend of gas (maybe even a couple hours of gas with those three Verado setups you see here).

There is no functional difference, just as long as it passes all the physical and electronic tests that are done during battery replacement. ACR did previously have a "useful life policy" that required units 12 years old or older to not be returned to service.This was to limit the maximum lifetime in the field to 17 years. They have since revised the policy to allow servicing of particular models, RLB-32 or above, that are in good condition and pass all applicable tests. However, 2 battery replacements is still generally considered the maximum one should do. If the unit is still in good condition, you would be fine replacing the battery. Assuming it passes all the tests of course.

There is really no logic with selling a beacon that somebody considers past it, out of date, old or not cost effective to replace battery compared to a new replacement.

To be cost effective there does need to be a bit more margin between battery replacement and total replacemen costst. There certainly does nor need to be a whole swag of ageing and typically unregistered beacons out there in the distress world.
