In reply to Zed.

Hi Zed. When you Google on ESR DIY you'll find a lot of them to build. Like these not digital with analog meter, for example:
1. http://www.electronicrepairguide.com/build-your-own-esr-meter.html
or this one:
2.http://electronics-diy.com/electronic_schematic.php?id=856

And I think I even remember having seen Digital versions with a PIC microcontroller and 16x2 Display from a Russian Author who also builds and sells them. And he shares the PIC hex file so anyone is able to replicate it.

But why build them when you can just buy a 12684 ESR/Semiconductor/Resistor/Coils tester KIT too? And at very cheap prices!

There also are other kits and other providers like Banggood and Aliexpress. Hope this helps.

Hi Zed, I can remember for your request for the ESR meter.
I made the esr meter year ago and it was on some printed paper the pcb and schematic.

I will see to check back where I put all that stuff and if I found it I will inform you through the administrator of this blog and of course I will share this info with you.

My best regards.

I would like to make one of your esr sir Christian to be used as a tester on electrolytic capacitors and non polar capacitors. Thank you sir Christian.

Hi!
Thanks for supporting my article, but I really don't know nothing about your project and I also didn't adopt anybodies project.
So, I don't know why you wrote:
"Hi Christian it seems my little project was clearly adopted by you without giving credit to the original thinker."
Maybe you have somewhere also a project posted before mine but that didn't restrict me to write my own text.
I also would read your text and of course I have nothing against to you or your text.
Please give a link to your text so I can read that too.
My best regards.

Hi Christian it seems my little project was clearly adopted by you without giving credit to the original thinker. but I'm glad it was put to good use somehow. I have made this project a long time ago but the only problem I encountered was the four terminal battery which was easy before when there were only three. But I still manage to overcome the problem by exactly doing what you mentioned here in your simple tutorial. The secret is the electronic chipset of the battery which controls the power from the battery. For your info I have a high end smartphone which model is Sky vega no 6. which I altered one of it's battery to use a 10k powerbank battery cell. the cell itself was disconnected to it's charging unit but if ever it will be drained I put it back to its original nesting place. I could provide the picture if you like. by the way I'm not into giving you a headache. it's enough for me to simply contribute my knowledge to the electronic world. Please a little consideration on other people's credit. Thanks and more power.

In reply to Phil Kafesu.

Thanks for supporting my article.
Some time wen I replaced the original battery with an aftermarket battery, in some model I got an error message "wrong battery", I also noticed on some models of aftermarket batteries does they goes warm or they can not last more then a several months or so.
All this situation and other what I'm not listed here is the result of a wrong BSI pin/connector ( whatever ) configuration.
It's better for me to separate the electronic from the batteries and than just join the original pcb from the original battery to the donor battery cells.
But, of course, there are so many possibilities...
My best regards and take care with batteries.

Thanks Chris. Here in Africa new batteries are expensive and sometimes you cannot find batteries of some phone models on the market so we depend on modifying old batteries.

Thanks for advising that batteries with the same values should be used instead of what we were doing here, that is: as long as it fits in the phone, its okay, we ignored other parameters like PTC ......
