This guide will give you step-by-step instructions on how to quickly swap out that old battery for a new one.

  1. Remove the five 7mm screws with H1.3 hex screwdriver. Remove the five 7mm screws with H1.3 hex screwdriver.
    • Remove the five 7mm screws with H1.3 hex screwdriver.

    Why is a H1.3 being used here when the screws look like TORX?

    Stuart Kerr - Ответить

    They are in fact TORX bits. A T5 driver fit neatly.

    Matthew Cole - Ответить

    On my watch, it was T6. T5 is pretty loose.

  2. Use a plastic opening tool to remove the face of the device to expose the inner components. There is one metal piece at the top of the face that is loose. This is the GPS antenna which will need to be removed as well. Be careful with the ribbon that connects the motherboard to the display.

    Is there a trick to attaching Ribon back on?

    brad - Ответить

    The GPS antenna is truly loose. It is not attached at all, but has to pins that guide it to a physical contact to the motherboard. It will literally fall out if you turn the open watch over. Replacement can only go one way.

    The ribbon connection end just needs to be used pulled up. No need of force.

    Trick to reattaching?

    brad - Ответить

    You do not need to disconnect the motherboard for this, and it is challenging to reconnect without risking damage. Recommend leave it attached and move onto next step

    Mark - Ответить

    You can remove the display ribbon cable by gently going back and forth with tweezers lifting each side of the connector. It pops straight up off of the motherboard. I initially did not remove this, but then had some issues later with attaching the batter so I removed it. Reconnection just requires lining it up and press with your thumb. It will “click/pop” when it snaps into the connector when reattaching.

  4. Using a T5 screwdriver, remove the two 5mm screws. The motherboard should now move freely.

    Fenix 3 does not have this ribbon.

    Asif Shafiq - Ответить

    Fenix 3 HR does. It goes to the HR reader in the back of the case. The connector was covered by tape so I did not disconnect this. Just be careful not to pull on the cable.

  6. Disconnect wires connecting battery to motherboard.

    Yes, not pulled backwards, just straight up. I wish I had seen this comment before hand. Maybe Victor could add it to the notes? Otherwise a great guide.

    I broke the black piece off the motherboard….. is this fixable?

    Paul Kadletz - Ответить

    This was the most challenging part. It actually took a surprising amount of force with the pointed tweezers to lift this straight up off of the connector. It does not slide in/out to the wire side, but comes straight up off the connector. I thought for sure I was going to break it. I think you could pull up on the wires of the old battery but you may pull the wires out it was so tight. That really doesn’t matter because you are going to dispose of the old battery.

  7. The battery is glued to the motherboard and will need pried off using the nylon spudger.
    • The battery is glued to the motherboard and will need pried off using the nylon spudger.

    This was pretty easy to remove. More of a double sided piece of gummy tape or something. However, the battery from iFixIt does not have the tape so I carefully pealed the tape off of the old battery as I could not find any double sided tape at my house.

    Frederic Huebner Jr - Ответить

  8. Now attach the new battery with adhesive and reassemble.

    Where is everyone getting batteries from? I purchased one off Amazon and it only lasted two hours after charging overnight. Thank you

    jerry quintana - Ответить

    The battery connector PRESSES in from the top. It does not slide in.

    Gale Otterholt - Ответить

    What type of glue should we use to glue back the battery?

    paul homberger - Ответить

    As Gale commented, the connector presses straight down onto the connector. I had a hard time getting both sides of the connector down. It will be level with the top of the black “dock” on the motherboard when it is all the way in. One side on my new battery went in easily, but it took some force to push the other side in. When you reassemble, do a test with no screws in to make sure the watch powers on. The battery has to be pretty well pressed against what I think is the vibrator motor on the left in the picture above (covered by the guy’s fingers) or the motherboard won’t fit back in the case. Easy to spot if it is not in the correct position when you try to reinstall the motherboard/battery.

    When reinserting the motherboard, I had to insert one end first. I think it is the side on the right in the picture above. It would not go straight down into the case. Take this opportunity to wipe off the gasket around the case.

    Frederic Huebner Jr - Ответить

    Any additional information on the glue/adhesive type that should be used? Thanks.

Does anybody do It in a fenix 5?

Fernando Alcaraz - Ответить

Same question. Fenix five /+ guide on the way?

Erik E123 -

Thank you. It saved me around over £100 to change the battery myself. Garmin quoted around £121 for battery replacement for out of warranty watch. I bought the battery around £15 and followed the guide to change the battery myself in my Fenix 3 watch. My watch does not have heart rate monitor, perhaps the ribon at step 5 is for HR monitor as I didn’t have it in my watch. Thanks again for simple, detailed and easy to follow instructions.

Asif Shafiq - Ответить

Where did you get the battery?

Alex -

Amazon or other 3 Party Sellerie use google for search the are tonns of Shops wich sell it

Andreas Kahl -

Howdy,

Followed all your steps but now the new battery will not charge. Could I have missed something in replacing the battery somehow? Pins not making contact or so?

Adrian - Ответить

I had a similar issue, I think you need to make sure the screws on the battery board are firmly tightened. Seems odd but worked for me

adagnall -

I’ve just followed these steps, and with £4.50 for a precision torx set, and £14.50 for a battery that came the next day by UPS, it’s saved me loads. The couple of things I would add are - you can use double sided tape to attached the new battery, and buy a battery with the connector already attached unless you are an electrician it saves the fuss, and make sure the connector is fully in place, it’s easy for it to be marginally out and you’ll get no power.

thanks!

Jason Clarke - Ответить

Can you please post a link to a suitable battery? especially that one with the “already attached solution” seems very interessting to me :) Thank you!

Marcus - Ответить

Do you think there’s room to put a larger MaH battery in there?

Brian Vinci - Ответить

Thank you very much. Clear and easy to follow. I would only add there how to detach the battery. Not to pull but pull up from the motherboard.

Thanks

Stanislav Vincent - Ответить

What about the seal after replacement ? Is it preserved so water does not pernetrate ?

Milen Genchev - Ответить

Has anyone had issues with the waterproofing after this repair?

LikeARabbit - Ответить

Hi,

thank you, that helps a lot!

Are there no new seals necessary and is the Garmin still waterproof?

Thanks!

Tom

thomas - Ответить

In my fenix 5 the battery connector is welded to the socket. Impossible to extract.

Alessandro Rossi - Ответить

Ciao Alessandro,

a breve cambierò la batteria. Davvero hai trovato i connettori saldati??

Puoi dirmi il codice del tuo fenix 3. Non vorrei che anche il mio fosse a saldare….

Ti ringrazio.

PS: sai se esistono batterie un po più capienti per il nostro Fenix3?

Grazie.

I’m looking for a guide for replacing the heart rate sensor on a fenix 5X. The resin covering the sensor is starting to crack and deteriorate after only a year and a half of use.

bat21 - Ответить

I know my Fenix 3HR had an issue similar to this on the sensor. It was a known defect with Garmin and they replaced my watch. I’d check with their customer service.

Ben Eige -

When are you doing a garmin instinct?

dml_222 - Ответить

I bought new battery replaced it with this instructions. Everything is working but the problem is that the new battery is weaker than the old one. It is discharging much more faster. Could it be that I need it to charge couple of times to see? Has anyone had this problem with new battery?

Matus Majersky - Ответить

Hello,

does the fenix 5 battery fit the fenix 3?

Felvégi Richárd - Ответить

Be very careful when disconnecting the wires that connects battery to motherboard (step 6). In my case the black socket broke off from the motherboard. Watch destroyed :-(
