Use the Suunto Battery Kit to replace your Suunto 3-series watch.

The Suunto Replacement Battery Kit includes a CR2430 battery, an O-ring, and a new lid, and fits Suunto 3-series watches, including the Vector, X-Lander, Altimax, Advizor, and Yachtsman. When you change the battery, carefully follow the instructions in the manual. Never use an old lid or O-ring. Check that the O-ring is clean and correctly in place before closing the battery compartment. This will ensure that the device remains waterproof.

It's a battery

  • Familiarity:I've put it through the wringer

Not much to discuss. It's a battery and it fits my watch. The amount of packaging was the only surprise.

Unanswered Question

my Vector was picked up at an REI Garage...

my Vector was picked up at an REI Garage Sale a few years ago, so I am guessing it is about 7-10 years old. Is the current battery kit also the same battery older Vectors use?


Everything you would expect

    Unfortunately, when you replace the battery on a Suunto watch, you must replace the rubber o-ring around the cap. The old one becomes distended over time and during removal. This kit comes with the new battery, cap, and o-ring, so you'll be good to go.


    Suunto Battery Kit

      Install kit works great. I bought my Suunto watch in 2007 and this is the second replacement battery. Be sure to make sure the watch back is clean before you unscrew the cover and the O ring is properly sealed.

      I formally bought the replacement kit inside my local REI. Since REI is reducing the SKUs they carry in the store, I was OK buying it on the web.

      do you have a delivery to israel?

      do you have a delivery to israel?

      Although generally we do ship to Israel, we cannot ship Suunto products out of the United States.


      Fits Vector

        This kit works great. I had to do a field expedient battery change and stripped out the plastic slot so badly that I couldn't reinstall it and seal my watch. This replaces the back piece and battery.


        Shipping OVERKILL

          The battery was just fine. But I was appalled by the shipping nonsense. First, the battery was $6.90, and the shipping was over $7. Then I understood why - a couple of days later the BOX arrived (see photo). "Whoa! What's this," I thought. After battling through the packing tape and the bubble wrap I eventually located the puny little watch battery in the bottom. As an outdoor based company, doesn't have some sort of environmental conscience? Wouldn't an envelope be sufficient?

          Shipping OVERKILL

          Suunto the best!

            kit is super easy to use, pop off the old and replace with the new cover and battery.


            Suunto vector battery life

              I've had my Suunto Vector since about 2000. It works fine, and I wear it daily. You do have to replace the batteries every 3-4 years, though. That seems reasonable to me, and the kit is easy to use.

              Is this Suunto Battery Kit is applicable...

              Is this Suunto Battery Kit is applicable to Mares Nemo Sport Dive Computer? You can check my Mares nemo here at

              No. This battery is brand specific to Suunto. I would look for a battery that is specifically made for the Mares Nemo Sport Dive computer.

              Mares makes their products with consumer-replaceable standard batteries available worldwide. Just remove the battery cover, make a note of the battery number and head over to your local hardware or electronics shop and purchase a replacement.

              Will this battery lid fit Mosquito Dive...

              Will this battery lid fit Mosquito Dive Computer?

              Looks like it is just for the 1st Gen. Vector, X-Lander, Altimax, Advizor, and Yachtsman.

              Will this kit have a seal and does it suit...

              Will this kit have a seal and does it suit the mariner watch?
