Hello,

I have a problem with most of my equipments, and it’s because they are battery operated. I would really like to remove the batteries once they die, in order to replace them with a cable plugged to the sector.

For example, I have right now a hair clippers that can totally run if it’s wired and if the battery is okay, but refuses to run once the battery is dead, even plugged in.

I have only basic electrical knowledge amd I’m afraid to simply make a bridge to replace the batteries. Would someone of you know what is the best/easiest solution ?

Thanks for your attention !

    Those don’t look like AAA batteries. They look like 18650 or some other sized lithium batteries which are far FAR more dangerous. A short in even a “discharged” battery could cause a fire.

    Op would need 4.2v (x2) to get the same voltage, and depending on the device god knows how many amps those batteries are capable of delivering.

      Except on the battery you can clearly read “SUPPO HS-AAA0.75”, which is indeed a NiMH 1.2V AAA battery with 750 mAh capacity.
