Introduction

The Motorola Moto 360 is very delicate. Utmost caution must be taken when using the tools. Use this guide to replace the battery in your device. The battery part numbers are FW3S and FW3L for the 42mm and 46mm respective case sizes.

  1. Heat an iOpener and place on the rear cover to soften the adhesive underneath.
    • Heat an iOpener and place on the rear cover to soften the adhesive underneath.

  2. Insert an opening pick or opening tool in the small notch by the microphone hole, underneath the plastic trim ring.
    • Insert an opening pick or opening tool in the small notch by the microphone hole, underneath the plastic trim ring.

    • With the opening tool under the plastic ring, move the tool around the edge of the watch, gently prying up the ring as you go.

    • Use fingernails or an opening tool or pick to pry the plastic trim off of the button.

      • Be careful to apply even pressure around the ring when prying, as there are three retainer prongs that can be broken if the ring is twisted or tilted while being pulled out.

    • Use a small six pin spanner to unscrew the button from the case.

      • If you don't have access to the proper spanner, you can use a pair of tweezers or a very small screwdriver to unscrew the button assembly.

      • There is blue thread locker on these threads, so light heat on the button side of the case may help.

    • Completely unthread this and remove the button assembly from the case.

    • Insert a prying tool into the notch near the microphone and slide the tool around the edge of the assembly while gently prying the assembly out.

      • The assembly is fitted very tightly into the case—it may take a little force to get your tool past the o-ring.

    • Do not fully remove the internal assembly yet. There is a flex cable connecting the assembly to the watch display that needs to be disconnected before the assembly is completely removed.

    • Use tweezers to remove a rubber strip on the back of the connector.

    • Use a fingernail or the tip of a spudger to lift the small locking flap on the connector and disconnect the ribbon cable.

    • Gently pry the battery out of the case.

      • The battery adhesive is stubborn, and the shield over the motherboard may come off with the battery. This is okay; use an opening pick to separate the battery and the shield, then snap the shield back onto the motherboard.

    • Do not pull the battery all the way out after you separate it from the shield. There is a fragile battery cable that must be disconnected before the battery is completely removed.

    • Remove the grey plastic piece that sits next to the battery.

    • Use tweezers or the tip of a spudger to disconnect the battery connector.

Do not pry out the inside of the watch like this says you will break the watch. The side button needs to be unscrewed first, I broke my watch by doing it like they say,
