Suunto Vyper Battery & O-ring

[Soggy]

I just bought a used Vyper with a low battery. I know the battery is a CR-2450, but what is the o-ring? The specs say 1.78 mm x 31.47mm which doesn't mean a lot to me...is there a number, like "014" or something? Do I really need to replace the o-ring every time?

Perhaps its in the manual? The manual is online, and I'll try to locate it for you, just in case.

I also want to get a spare, to keep in my save-a-dive kit

The measurements I gave are what are listed in the manual. I'm looking for the O-ring number that I can go to the hardware store with. For example, a yoke tank o-ring is "014", not x.xx mm by xx.xx mm.

31.47 mm is awfully large!

Its k5664, according to the manual. I realize this is a Suunto number...

you need to get a metric o-ring... the hardware store most likely isn't gonna have this one... check online... I have a catalog that may have the size listed in it... I wouldn't mess around with this size though... a waterlogged dive computer isn't fun at all...

better to reuse the old one that use the wrong size... make sure you lube it up properly and that it isn't damages and it should be ok... I've done that myself... but do it at your own risk...

lube it with what?

Actually, I'm pretty sure that the battery comes with the O-ring, or vise-versa.

Not if you buy the battery at walmart for $1.96 vs $10 or so at the dive shop.
