Thanks a lot, you did not just save me money, but the whole watch...since there is no specialized dive shops who could do it for me. Thanks again. Thumbs up
Came for battery replacement. Learnt general maintenance. 10/10 would watch again.
Great video. One thing that bit me in the butt was that I did not keep pressure on the back of the watch when I was reinstalling it. The spring pushed the back out a little, and messed up the O-ring seat. I tested the watch by putting it in distilled water. After a couple of hours, I noticed water in the display. I took it out and dried it overnight with a fan. I repeated the process, but kept pressure on the backing. Kept it in distilled water for 24 hours, and no leaks. Will take it down to about 100 ft in a few weeks. I'll post again if it leaks. Use distilled water for the testing. If it leaks (like mine did), it is likely not to cause any damage. Testing it on your first dive will likely ruin the computer if it leaks. Lesson learned - keep pressure on the backing when replacing it. If it moves before you get the both screws snug, remove and reset the O-ring.
Yes correct, fingers crossed all will be fine
Thank you for sharing these instructions - very useful!
thx bro! it helped me to make it by myself ! cheers from switzerland
Thank you, very useful and complete. :)
Very useful and it helps a lot.
Thank you very much, this is very helpful! :-)
thank you , you saved my money :)
You've got really nice hands 🤩 Thanks for the video, useful. What is the number of the battery for Mares Smart? I can not really see it
😂 Thank you! Battery is CR2430
FYI If you have a Smart Air version, the kit comes with a 2430 battery, the Air version uses a 2450 battery. Everything else is identical.
Hello , could you give me the link where I can buy a Kit battery replace to Mares Smart Apnea
Any SSI diving centre should have them,
Otherwise we can send it to you. Drop us an email on freedivingtenerife@gmail.com ;)
@@atlantisfreediving I send a mail because I dont have any SSI diving center in my Country Perú, I appreciate if you can answer me. Thanks
The manual says do not lubricate, although when changing the battery for the first time I have noticed there was some lubricant on the original O-ring.
Generally you have to apply O-ring lube (silicone grease) when changing or servicing them. Some exceptions are likes of action camera o-rings on UW housings etc. Lubricant will make sure Oring sits into its right position when closed.
@@atlantisfreediving I did actually asked Mares about the issue. This is their reply: "The O-ring should not be lubricated. You may have found residuals of lubricant when opening the battery cover - this is not from the O-ring, but from lubricant used by Mares around the battery cover when mounting it to the computer." But the lubricant was clearly impregnating the O ring and in the compartment of were the O ring was, which seals the whole of the diving computer, not just the battery compartment, so their reply does not explain why the O ring was impregnated in lubricant and there was some white stuff where the O ring is located (unless they call both the battery compartment and they put a layer of lubricant where the O ring sits). That was the first battery replacement. So clearly Mares put lubricant either around the O ring or in the compartment as you say. Thanks
what dimension have the o-ring ?
Not sure, we buy original replacement from Mares for this particular model 🤷🏻♂️
When i turn the light on, the writings fade..any idea? my battery doesnt show its low...thank you
You can try to adjust your LCD display contrast, but this can also be a sign that your battery soon will need to be changed :)
@@atlantisfreediving i see..Thank you
@@atlantisfreediving i contacted the store, they will replace it, they said its a defect.
i don't think anything about the mares matrix battery
Bizar, I think I did all that, but still my computer (2 of them) started leaking water. The only thing I did maybe wrong was putting too much grease on the o-ring, could that be the problem?
@Hmbucker yes, this can be the problem. Too much grease can cause a leak.
friend could make the mares matrix or tell the battery code
CR 2430 is the battery code
can i use Vaseline instead of grease? Thanks
well, I used vaseline lol. Ill keep you guys posted. I think I used it in the past with no problems anyway
@@blink882 Normally I wouldn't recommend Vaseline, as it can react with the Oring and swell it up. Let us know how you got on :)
I just noticed that you put strips other way around :-p
OMG another OCD case HAHAHA! Good eye ;)
The manual specifically states:
"NOTE
Do not lubricate the o-ring! Lubrication
causes the o-ring to twist when the cover is
put over it, causing the watch to flood."

This is very weird, and you are right, the manual says this, however we noticed that battery kit contains already pre-lubricated O-ring, generally O-rings are lubricated to prevent the exact issue, make sure not to OVER lubricate the O-ring would be the right message. That said, we have been changing batteries in this and other computers following the same steps and never experienced any floods. It is needed to say that back cover does not twist in to the watch, it sits straight on it, no twisting needed to apply, just push straight down, once aligned with alarm connectors and screw holes. Good luck!
You made a mistake when you mounted the belt... Need change the halves...
Hello, by halves you mean the screws? I often don't feel they need to be changed if they are fine, so I keep the old ones :)
@@atlantisfreediving No, no, I mean halves of the strap...
@@romanermashov1578 maybe I did 😅
@@atlantisfreediving I am a very attentive viewer😁 Thanks for video, today I'm changed the battery in my Mares Smart. All was fine...
@@romanermashov1578 yes i see... 😅 thank you for commenting 😇
you made the video wrong, put the straps back on upside down, which prompted me to do the same, please delete and repost maybe?
Yes you are correct, however it is not a fundamental mistake, we won't delete the video but we will make an element to address this mistake. Thank you for the comment 😊🙏
