    • Place a spudger into the small gap between the plastic frame and the battery, opposite the display cable.

    • Carefully pry the battery up and out of its recess.

    • The battery is adhered to the core with mild adhesive. If it feels stuck, lightly heat it with an iOpener or hair dryer to soften the adhesive underneath.

    • Don't try to fully remove the battery just yet, as its connector is still adhered to the core assembly.

    • Use a pair of tweezers or your fingers to remove the battery.

    • Don't accidentally poke or slice the battery with any sharp tools. A punctured battery may leak dangerous chemicals or catch fire.

    • Never reuse a deformed or damaged battery—it's a fire hazard. Replace it with a new battery.

    • To install a new battery:

    • Use tweezers or your fingers to remove the old adhesive from the frame.

    • Use high-concentration isopropyl alcohol (>90%) and a lint-free cloth to remove any remaining adhesive residue.

    • If your replacement battery isn‘t already equipped with adhesive, apply thin, double-sided tape such as Tesa Tape directly to the battery recess where the old adhesive was.

    • Lay the replacement battery in its recess and press down firmly to secure it.

Are there any recommended batteries to replace the OEM one with?

Caleb Angell - Reply

Hi Caleb Angell, while I can't give a specific recommendation, replacement batteries might be found using the part number: EB-BR910ABY (44 mm model) and EB-BR900ABY (40 mm model).

Is this good for the watch 5 pro too?

Antonella Carletti - Reply

Hi Antonella Carletti, I think it's reasonable to assume so from a quick look at the Watch5 Pro specs and look, but I haven't handled the Watch5 Pro myself and was unable to find disassembly resources, so you should take this as more of a guess.

Thanks for your response Manuel, I'll give it a go.
