Cobra Battery change

[CotoChris]

Is changing the battery of a Cobra a complicated job? On Saturday's dive it gave me the first low battery warning with two bars. I called my LDS and it said they would send it to Suntoo and it would take 2-3 weeks. OK he said it would be calibrated but surely a simople battery change can be done relatively simply. Does it have to be calibrated if you change the battery?
I don't fancy being without it for the next 3 weeks. I'm thinking if it's possible to change the baterry and then send it to Suntoo at the end of the season for calibration.
As it has two bars is it fine to use until one bar appears. If so it could last for the next couple of months dives.

I changed my own it took about 10 mins total. I am ashamed to say I even used the old O ring and just put grease on it. I've had about 100 dives with it since the change so I must have done it correctly. Also if I remeber correctly the battery compartment is isolated from the electronics so even if you do mess up the computer is OK once you sort out the battery. I bought my battery for Maplins in the UK it cost £3 as I remember.

I found this video:

Suunto Vyper Vytec Cobra Gekko battery change

What batery does it use?

Looks simple enough, any special tools needed?

chris,

actually ignore that link. Wrong one...

I did mine on my Vytec, took about 2 minutes. Reused the o-ring its got about 20 dives on it with no problem.

Chris It tells you how to do it in the user manual. On my printed copy its on page 56 it really is easy. Its a 3V Lithium coin cell.

[CotoChris]

Thanks. I dig up the manual and clear the dust. I spoke to LDS, they won't do it but will get me the battery 'pack' presumably including the fresh O-ring.

Did you loose your memory by chance ( the computer that is?)

[colinpjenkins2]

Memory stayed in as I recall. I had downloaded it up before hand. Certainly the total dive time stayed.
Just found the battery information its a CR2450 maplins code L66AJ (but guess maplins noy much use in Portugal)

Nope, but I popped into my local watch repair/battery supplier and he had some - cost me 1 rial (£1.30)!

Just did it. Took less than five minutes and that was taking my time. Will dive tommorrow to see if succesful but would be big numpty if I got it wrong! Go the Suunto battery kit costing me €17. This is batery, o ring, plastic cover and batery holder.
