We agree with iFixIt - you have the right to repair. Below are a few ways we can help you maintain a functional device, forever.

If you know what you're doing, shop for replacement parts here:

https://shop.trmnl.com/collections/replacement-parts

We'll sell you one for $50 (including shipping), or you can get this Waveshare one in US Store or this UK Version. You can order directly from our shop (for OG or for BWRY) and see our disassembly + assembly guides.

Have access to a 3D printer? Check out the open source designs here.

Alternatively we'll send you a native case for $15 + shipping. Email [email protected] and see our disassembly + assembly guides.

Unfortunately we can't send "loose" batteries, but this one (1000mAh) will fit and has been purchased/tested by TRMNL previously.

This 2000mA option would be fit and work properly: Amazon - B0DTHG757X

Here is one more that we have not purchased but hardware team validated (based on listing) as compatible on June 26, 2026: 2000mAh #103450.

Alternatively this option provides 3x the power (3000mAh), but does not fit in the native TRMNL enclosure. If you prefer a longer battery life, consider pairing the larger battery with one of our many 3D printable case designs. Watch this assembly video for installation steps.

This 1200mAh option would fit (it's less wide, so it fits despite not having the dimensions mentioned above) and work properly: https://ampul.eu/en/battery/5825-li-pol-battery-1200mah-37v-753334

This large capacity version would be a very tight fit, it already has a proper connector, a large capacity, and an integrated protection board https://ampul.eu/en/battery/6148-li-pol-battery-3000mah-37v-103665

We'll send you one for $20 (including shipping). Just order directly from our store (for OG or for BWRY) and watch this assembly video for installation steps. We will also flash the latest firmware on your behalf, or you can do so in 1 click here.

We'll send you a new one for free, plus a little help for postage. Email [email protected] and follow these steps to replace it.

Our OG model uses M3-0.5 x 4mm screws to attach the PCB to the back enclosure. Get more with the same specs here.

We can sell you a replacement screen for $70 right in our shop. Feel free to follow our re-assembly guides, or contact support if you want to ship the device back to our warehouse so we can do the repair for you.

All screws are torx, stainless steel, magnetic

Note: The above image has imperfectly aligned screws which can lead to dock connectivity issues.

USB-C

Any cable with power + data should work, but we can sell you one for $5:
