What happens if you lose the springs?
I disassembled my watches yrs ago & they're put back somewhere. I'm sure I've lost the springs by now.
I'm thinking about buying a battery & replacing it in one of em. If the springs are necessary for the watch to function, I'm not gonna bother.
I kinda doubt that's the case tho.
Will it work without the springs?
I took voltage measurements again the other day. Straight from battery pins, it was actually over 2 volts. There's no voltage going into puck tho (past the BMS).
I was glad to see the batteries aren't really dead. I'ma try giving em a boost like you suggested & see if anything changes.
I'd think 2+ volts would be enough for the BMS to recognize it and allow charging from normal charge points, but maybe not.
Once I try it I'll come back and let you know how it went.
I'm just now seeing your response. It's actually been awhile since I tested the battery voltage, so I'm not sure where I placed the leads to measure voltage. Thanks for replying cuz I hadn't considered the BMS possibly causing the voltage appear to be 0.
I'm no battery expert either, but I was under the impression lipo batteries cannot be allowed to discharge completely or they can't be revived. I did know the older chemistry rechargeable batteries could be revived. Can't think of what they're called right now.
Thx again for taking the time to respond. Ill check back into my battery when I've got some time & see whether its actually dead or not and try reviving it if so.
Awesome of you to post this DIY. There's hardly any info online regarding the batteries in this bottle.
Why couldn't you solder the protection circuit to the battery you replaced the old one with?
My bf gave me one of these bottles but without a charger. I realized my old Pebble watch charger fit perfectly & tried charging the puck with it but it didn't do anything.
The battery reads 0.00v with multimeter. Since you said the battery has over discharge protection, that likely means the battery needs replacing huh?
I'm gonna go out on a limb and say this is likely the 1st generation model.. No screen.
I say that bc I had the 1s version (the very 2nd band xaiomi came out with) & there were several more components than shown in these photos.
There's no need for a disassembly guide cuz on these older ones cuz once you get into it there's no putting it back 2gtr. They're completely sealed all the way around.. (Like plastic soldered.. If that makes sense). Reason being, to make it waterproof.
The point of this article was obv to provide the info about what electronic components are inside the Mi band & that was done perfectly well.
It's too bad there aren't more ppl like the person who posted this showing components inside other fitness trackers.
yes this is Def not the same as my 7th gen but it's an 8 inch so maybe that's the difference.. all I see is 4 screws holding down the motherboard n I've removed them but still can't get the board loose.. it's like one side of it is held down under these plastic tabs that don't move..
thx 4 this! it showed me it's not rly worth buying this phone off eBay with a battery that needs replacing. while I feel pretty secure that I could replace the battery using this (extremely well explained) guide, I don't rly feel like investing this much energy into something that could potentially further damage my phone, so the search continues to replace my note 4 that had the eMMC bug :/
