How to change the battery?

[EvolvePlease]

Mudi works without connection to battery pack - we have verified. No battery, no problem.

@biorkar

many thanks for taking the time to share pictures of the battery disassembly. Mine turned into a spicy pillow to the point it broke three cover clips.

I was already about to dispose of the battery but reading other posts, I'm planning to remove the PCB/BMS in case someday I can get a third-party battery replacement. Any advise on how to do it? The battery seems dangerously swallowed swollen and I’m concerned it might rupture.

As a side note, my experience with the Mudi, from the modem upgrade limitations to now realizing I can't get a battery replacement, has honestly made me distrust GL-Inet and their products. Running OpenWRT, supposedly being possible to upgrade or repair was what led me to buy this mobile router and spend almost 200€. In the future my intent is to avoid any GL-inet products. Maybe Mudi was too ambitious to begin with, maybe it was me that didn't fully understand what Mudi was meant to do, but not providing a way to replace the battery is against consumer rights, even if when it was released GL-inet wasn’t mandated by law to provide spare parts. At least, unlike other devices, Mudi works without a battery plugged in, I’ll give it to them.

Edit: swollen, not swallowed. My spellchecker must have taken a day off.

Regarding MUDI, I have not seen anything similar in terms of a compact 4G router.

If you know of any, please post here.

As for replacing the battery, I agree that it would be great if users could replace the battery themselves without throwing away the device, so as not to pollute our already dirty world.

I don't know why GL.INET isn't working yet? => Modular Router !

It's beneficial both economically and environmentally.

All users would buy batteries or other parts from the company that sold them the device.

Here's a great example of how it works.

Checking in 1.5 years later – my replacement 605065-based battery pack is still working and keeping the mudi alive and kicking.

Hi @Matrix
Thanks for your feedback.

If you have a photo of the battery you replaced and it’s working properly, please attach it here; I’m sure it will be helpful to other users.

Nice work bro.

If anyone has statistics on how long the battery lasted from the time of purchase until it failed, it would be interesting to know.
Is it two years or more, depending on usage?

1. Are there any third-party manufacturers selling such batteries?
2. How can I extend the battery’s lifespan?
3. Is it possible to buy a new battery from GL.iNet?

Hello! I managed to separate the two swollen pouch cells from the charging controller and spot-weld two 18650 cells in parallel in their place. They fit perfectly inside the battery compartment, and everything is working great so far.
