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.

  1. Insert an opening pick into the thin gap between the back cover and the front shell, along the edge of the right grip. Pry up on the back cover to release it from the locking clips.

    • Pry up on the back cover to release it from the locking clips.

  2. Once the clips are disconnected from one edge, the rest disconnect easily. Grip the back cover at the opening you just created and pull it up and away from the device to unclip the long edges. Remove the back cover.

  3. Use a pair of tweezers to remove the piece of foil tape covering the hidden screw on the board shield. If possible, try not to rip or tear this tape so it can be reused. If necessary, you can fashion a replacement by cutting a piece of aluminum foil tape to fit.

  9. Carefully peel the audio cable off of the battery. The audio cable is secured to the battery with some light adhesive. If the adhesive is stubborn, don't force the cable. Lightly heat the audio cable using an iOpener or a hair dryer to soften the adhesive.

    • You may want to tape the audio and button board cables out of the way as you remove the battery.

  12. In order to slice the battery adhesive through two small slits near the bottom of the Steam Deck's frame, two thin cards are needed. Use a pair of scissors to cut a plastic card in half, longways. Round over any sharp corners, as they could scrape or puncture the battery.

  13. 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.

  14. Insert an uncut plastic card between the top edge of the battery and the frame. 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. 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.

    • 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 - 返信

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.
