When it comes to having a well-built watch with an improved and innovative designed battery, look no further than the Garmin watch.  The brand Garmin manufactures its watches providing a rechargeable lithium-ion battery.

Therefore, generally, you don’t need to replace the battery of your Garmin watch unless there is a power-related issue that leads to changing the battery.

Well, in this article, I will cover up the battery-replacing-related issues of your Garmin watch. Besides, I will let you know whether your Garmin battery needs to be replaced and, if so, how you can replace it.

Can your Garmin watch batteries be replaced?

Well, according to Garmin, their outdoor watches with rechargeable lithium-ion batteries are not usually user-replaceable. However, they seem to be user-serviceable batteries.

Replacing the battery of a Garmin watch is usually done when the battery has power issues, such as if your watch battery is not charging or your watch loses battery power quickly. And, you rarely have to change your watch battery due to battery failure.

Moreover, if the rechargeable battery of your Garmin watch dies and you can’t recharge it anymore, only then, it needs to be replaced to ensure the watch’s optimal performance.

However, in most cases, the power-related issues of the battery can be solved by taking some troubleshooting steps.

Yet, if you have gone through all the common troubleshooting steps but can’t solve the problems, you should go to the Garmin Support center to resolve the issues or change the batteries.

You can also replace the battery on your own, as replacing the battery of the Garmin watch in some of their GPS units is pretty simple. And, you can find the replacement rechargeable battery on the Garmin website.

How do you change the battery in your Garmin watch?

So if you need to change the battery of your Garmin watch, you should first determine whether your watch has a replaceable battery with the Garmin GPS units.

You will find this information on your Garmin watch manual. You can also know it by checking the GPS unit’s sides and backs of the watch. However, if there is a battery and you want to replace it, follow the given instructions step by step.

  • First, you need to remove the watch device from the wristband. And then, you have to remove the front battery cover by pulling it off with the help of a small Phillips screwdriver.
  • After that, you need to gently press to slide out and remove the existing rechargeable battery from the battery cavity.
  • After removing the old battery, insert the new rechargeable battery into the battery compartment of your watch. While doing so, make sure that the gasket tabs are perfectly aligned with the appropriate notches.
  • Now, you need to replace the front battery cover again and ensure that it is automatically locked up and secured the battery cover as well. For this, you should firmly tighten the four screws.
  • And finally, insert back your watch device into the wristband, and you are done with it.

Here, I have provided a battery-replacing video of the Garmin watch to help you understand the steps better. Besides, by following the video, you can also learn how to change the battery in your Garmin watch more conveniently on your own.

How long do the Garmin watch batteries last?

I have mentioned before that the Garmin watches feature rechargeable batteries. Besides this battery, the brand Garmin also offers some fitness trackers, GPS, mapping, etc.

Therefore, due to these features, your Garmin batteries usually lose battery capacity over time because of charge and discharge cycling issues.

However, in some Garmin watch models such as Vivo smart, Edge, Forerunner, etc., devices, the original battery capacity remains 80% after a few years of the battery’s frequent charge and discharge cycles as well.

Well, in the case of measured charging time, the battery lifespan of the Garmin watch usually depends on the watch mode, such as Smartwatch mode, GPS mode, expedition with GPS activity, broadcast mode, etc.

With a single and full charge, the rechargeable battery of the Garmin watch can last well up to 5-7 days with typically 3-4 hours of running. And, if you don’t turn on the watch’s mode like GPS mode, it can last well for at least several weeks.

Yet, the battery capacity degradation also depends on factors like exposing the watch to extreme temperatures, leaving the battery entirely charged and discharged for a long time, like more than 2 weeks.

Therefore, if you want your Garmin watch to last a long time, you need to charge it fully and obviously regularly and shouldn’t leave the watch for a long period, either charged or discharged completely.

Besides, you should be aware of factors that shorten your watch battery’s lifespans, such as backlight, smart notification frequency, wrist-based heart rate, etc.

Why does your Garmin watch not hold a charge?

All right, if you’re experiencing that, your Garmin watch doesn’t hold a charge; most probably, the reason is your cable adapter may be depleted, or maybe the battery has a power-related issue.

If the cable adapter is depleted anyway, it doesn’t function anymore, resulting in charge holding trouble. Moreover, as the Garmin watch provides a rechargeable battery that possesses several charge cycles, therefore, after that, the holding charge of the battery will become less. 

Besides, it also doesn’t hold a charge if you expose your Garmin watch to direct sunlight for a long time or put the watch in extreme temperature for too long.

Final thoughts

So, finally, I’m done with it. I hope you have already gone through the article and found out the details about the battery replacement of your Garmin watch.

In most cases, there is no need to replace the batteries. Yet, if you need to change the batteries, you will find them available according to your watch models that are relatively much easier to replace.
