My TC1 Tester used to discharge in few days without use. I thought the battery was small. I replaced the cell with a larger capacity. But the problem didn't solved. After watching this video, I done the same. Now my cell continuously work without any problems. THANK YOU VERY MUCH SIR . ❤❤❤❤❤❤❤❤❤❤❤❤

For the lesser mortals, you didn't say that you must switch the unit ON when you need to charge it. 🙂

[@Joftec]

Yes that is true, the charge indicating led confirms that too.

[@mikepanchaud1]

I did the same, but used a small toggle switch so i can easily tell when it's off by looking at it. It's definitely worth doing..

[@surgingcircuits6955]

Will do that to mine immediately. Nice and simple. Switch ON for charging!

[@Joftec]

Yes switch has to be on for charging, confirmed by the red charging LED

Thanks for the video. I have several instruments that could use a mod like this. You might consider gluing a ring around the switch so it can't be activated when the instrument is bumped. I have that trouble with one instrument.

You could file the button down a bit also. Or just round off the edges.

[@Steve_Coates]

I used a slide switch for mine as the case I keep it in is a tight fit.

I'm going to pretty much just install any small toggle switch I have on hand;
a simpler, cheaper, and faster modification.
I've also not found any "micro" style push-on/off button switches that are electrically reliable for any reasonable amount of time before I'm replacing them.

[@Jogmaster9]

Great idea, mine is exactly the same, where did you get the switch?

[@Joftec]

AliExpress, pretty sure they are available on eBay and probably others too

[@G1ZQCArtwork]

I have the T7 version of this tester, they seem to have fixed the problem, I can leave it for months and it does not go flat in storage.

[@Joftec]

Good to know thanks

[@pault6533]

Same here. However, it can get locked up when attempting to test some 3 pin devices which o suppose are not in its database. The only way to reset it is to temporarily remove the cell or let the cell discharge. Therefore I put a switch on mine for reset purposes.

[@saydmarschany8321]

Hi, I like your modification procedure. Would you please tell me what the switch is called and where to find it? Having the same problem with my tester. Thank you.

[@Joftec]

Hi, the switch was purchased from Aliexpress. I think it is called a Self Locking / UNlock Push Tactile Power Micro Switch . The size is 5.8mm x 5.8mm long button. Hope that helps

[@saydmarschany8321]

Thank you very much for your response, went ahead and purchased from aliexpress. Will have fun when it arrives.

[@Johny666EU]

i wonder, if you turn off battery is not reseting calibration settings?

[@Joftec]

Hi, yes that may be the case. I do the calibration every time I need accuracy anyway .

[@jamesrodemeyer7544]

Nice that you admit making a mistake. Good show.

[@Joftec]

Thank you sir
