Can anyone help me about battery replacement of Nihon Kohden Tec-7621K Defibrillator?

I replaced the battery with a fully charged one but the device is still giving "time to replace battery" message.

Welcome to the forum. smile

Check out the manuals available at Frank's site.

It looks like the manual headed Nihon Kohden TEC 7600, 7700 covers the TEC-7621K as well.

Take a look at page 4.14.

If you don't inspect ... don't expect.

Hello Fuat, in defibrillator TEC 75XX or higher i think there's a resistor called R0831 positioned on facedowmn of motherboard that is 10ohm value. This resistor should be change with another resistor of a new value of 49,9ohm 1/5 watt

I hope that you solve your problem smilewink
