We have a Xiaomi Mijia 1C robot vacuum that we purchased in 2020.

It has been a great product until yesterday.

We set it running and bumped the suction up to the highest setting (usually just use the default).

It partially completed it's work and said it was going to recharge and complete the job later (which is what it is supposed to do of course).

Several hours later I noticed it was still showing as 'charging' - but the percentage was stuck about 50%.

I have since tried:

Cleaning the charging contacts (they were clean anyway)
Powering the vacuum right off
Removing the battery for an hour (would be very easy to replace on this model).
Factory reset

It still just shows the 'pulsing' Home button when it docks and the battery %age doesnt increase.

I suspect that maybe at 4 years, the battery has failed.

There were a few of these sold in NZ - Has anyone had a similar issue of managed to source a 'decent' replacement battery?

Aliexpress has a lot of 'replacements' but it is Aliexpress....

I would still go with Aliexpress. Let's face it most of the stuff we have in our devices come from the same factories :)

Yes - I guess so.

Probably just try and find the vendor with the most sales of that item and the best feedback.

In case anyone else ends up looking for something like this.....

I purchased this from Aliexpress:

They said they had sold around 600 when I ordered - it now shows 800+ sold - and had positive feedback.

They have 5600mAh, 6800, 9800 and 12800 options.

The original was officially 2600mAh.

I selected the 9800mAh variant that was $38 + around $6 for delivery ($44 all up).

You can never be really sure how legit the 'increased' battery capacity on Aliexpress actually is but figured over 3 times the original capacity would be great if it was true.

I ordered the item on 8 July and it said expected arrival date was 14 September (over 2 months). I figured it was coming by sea.

On 23 July (15 days after purchase), the courier dropped it off at the front door - nice.

Took the old battery out and popped the new one in and left it overnight to charge - though the battery was actually something like 80% when I installed it.

It charged fine, reached 100% and the charging lights went off as they should (but weren't with the old battery).

Next day I got it to do the whole ground floor - it went for 65 minutes and battery went from 100% down to 74%. Normally it would have been pretty low after a complete clean - so it does seem to have extra capacity compared to the original.

It has been run a few times since then and the battery seems ok. Fingers X'd it has a reasonable life span.

Nice, glad to hear it worked out well.

Thinking of doing the same for my Eufy L60.

Update: Nothing on Ali for that model.

Wonder if it is/was sold under another brand name?

I have had a look and agree they seem pretty hard to find - there are official sites, but they dont ship to NZ.

The local support seems to be https://www.myanker.co.nz/

Might be worth giving them a go?

Yeah prefer not to go down the official route as I want a higher capacity.
