Introduction

Use this guide to safely remove and replace a worn out or dead battery in a Steam Deck.

To minimize risk of damage, turn on your Steam Deck and allow the battery to fully discharge before starting this procedure. A charged lithium-ion battery can be very dangerous if accidentally punctured. Heating a charged battery is a fire hazard. If your battery looks puffy or swollen, take extra precautions.

Note: The battery is strongly adhered to the Steam Deck, requiring repeated heating and prying cycles. The heat produced by an iOpener may not be sufficient to loosen the adhesive, so a heat gun (or, alternatively, a hair dryer) is recommended for this procedure.

Before you begin, unplug all cables from your Steam Deck. Remember to follow general electrostatic discharge (ESD) safety procedures while repairing the device.

Don't reuse the battery after it's been removed, as doing so is a potential safety hazard. Replace it with a new battery.

    • To minimize risk of damage, turn on your Steam Deck and allow the battery to discharge completely before starting your repairs. A charged lithium-ion battery can be very dangerous if accidentally punctured.

    • Before starting this guide, power down your Steam Deck and unplug any cables.

    • As an extra precaution, Valve recommends putting your Steam Deck into battery storage mode within the BIOS before starting any internal repairs. Read how to do that here.

    • If you have a microSD card installed, make sure to remove it before opening the Steam Deck.

    • Use a Phillips driver to remove the eight screws securing the back cover:

    • Four 9.5 mm screws

    • Four 5.8 mm screws

    • Throughout this repair, keep track of each screw and make sure it goes back exactly where it came from to avoid damaging your Steam Deck.

    • The battery is strongly adhered to the Steam Deck. The adhesive loosens with constant, steady force, and it will require repeated heating and prying cycles.

    • Heating a charged battery is a fire hazard. Make sure you've completely discharged your battery before starting this step.

    • Don't reuse the battery after it's been removed, as doing so is a potential safety hazard. Replace it with a new battery.

    • Use a heat gun to heat the adhesive underneath the battery for 1-2 minutes.

    • Alternatively, a hair dryer may also be used.

    • Try your best to not overheat the battery. Keep the heat gun or hair dryer ~2 inches above the battery and constantly moving at all times—don't keep it heating one place for too long.

    • Insert a second plastic card between the right edge of the battery and the frame.

    • Don't use excessive force or pry at the battery with metal tools.

    • Try your best not to deform the battery during this process. Soft-shell lithium-polymer batteries can leak dangerous chemicals, catch fire, or even explode if damaged.

    • The battery most likely won't budge at this step, but these cards will be helpful as leverage as you continue.

  15. Steam Deck Battery Replacement, Reheat the battery adhesive: step 16, image 1 of 1
    • You'll need to repeatedly reheat the adhesive to further soften it. The adhesive is tough and it may take a few tries to get a card started under the battery.

    • Try your best to not overheat the battery. Keep the heat gun or hair dryer ~2 inches above the battery and constantly moving at all times—don't keep it heating one place for too long.

    • Insert a plastic card along the bottom edge of the battery to pry the battery away from the frame.

    • Lift the battery up, away from the Steam Deck to fully separate it from all adhesive.

    • Don't use excessive force—try your best not to deform the battery during this process.

    • If you're having trouble, repeat the heating and prying process around all edges until the battery becomes loose.

  19. Steam Deck Battery Replacement, Remove the battery: step 20, image 1 of 1
    • Remove the battery.

    • Don't reuse the battery after it's been removed, as doing so is a potential safety hazard. Replace it with a new battery.

    • To install a replacement battery:

    • Dampen a lint-free cloth with some isopropyl alcohol (>90%) and use it to remove any remaining adhesive from the battery well.

    • Peel and discard one side of protective liners on the new adhesives and apply them to the new battery, using your old battery as a reference for where they should adhere.

    • Peel and discard the remaining side of adhesive liners. Lay the battery in place and press firmly.

    • Remember: Don't reconnect the battery connector until you've finished reassembly!

Is it safe to apply small amounts of >90% isopropyl alcohol under the battery to loosen the adhesive bond? Or would that drip into the screen or other components and potentially cause damage?

RikiGuitarist - Reply

Your mileage may vary. Isopropyl alcohol may be an effective method to loosen the adhesive, but you run the risk of excess leaking onto or into the display or other components, due to the cutouts on the battery tray. Your second sentence is spot-on, hence the recommendation to carefully use heat instead.

Carsten Frauenheim -

Why couldn’t they of used pull tabs for the adhesive so this process would not be so difficult and tedious. It would also be less risk of over heating the battery/steam deck or puncturing the battery. This is really the only design choice I can criticize of the steam deck. Pull tabs would of made this a repair the average person could achieve.

It seems crazy to me that they made this process so difficult, surely battery is one of (if not THE) most common things that you'll need to eventually replace? I suppose they must have been limited by what they could achieve?
