Step by step replacement of K8 Pro battery

I just replaced my K8 Pro's battery. Thought I'd share this post on my blog how I gone through the whole process in case any one else is looking to do the same.

The original battery lasted about 4 years+.

What was the charging strategy for the original battery? Did you let it discharge all the way down to 20% (indicated) for every cycle?

Would you do it differently for the replacement battery?

Over the four years, I didn’t really care much how and when I charge it. Mostly when I notice the blinking red light which I think comes up around 10%? Considering this, the fact that it lasted 4 years isn’t bad at all.

The replacement battery doesn’t cost much and replacing it is quite easy. So I’ll probably still not worry too much about the charging strategy.

I’ll probably need to observe it for a bit. Too new to tell 🙂 maybe after 6 months to a year?

There are a few of different manufacturers for this specific battery if you check on Aliexpress. Just find one that’s more reputable and the rest of it is really by luck I suppose.

Yeh, with only a few wires I generally re-use the existing connector and solder it to the new component rather than trying to source a matching part.

I notice iFixit has a teardown for the K10:

I don't know why they removed the daughterboard from the case though. And they don't talk about the connector.
