Running Hair Trimmer DC Motor (1.2V 600mAh) Directly from AC-DC Adapter—Possible?

First of all I'm in my first year in engineering school and I want to join the electrical dep.

Hey, so as the title says I have a hair trimmer works on a 1.2 rechargable battery 600 mAh, and my problem is it takes hours to be fully charged and only works for less than 5 minutes so I thought of getting an AC-DC Adapter so I can use it directly with recharging it everytime so I bought one and when I tried it it didn't work properly and don't know what the problem is exactly, any help would be appreciated.

thanks.

Hi Shawky Khalil,

your bat v is 1.2 v with a current capacity of 600mah
here you require a charging voltage of 1.44v and a charging current of 60 ma.

you can use the ac -dc adapter , put the range on 3v connect a1 watt 47 0hms resistor in series with the positive terminal of your power supply also connect a diode in series to the resistor make sure the cathode of the diode is connected to the positive of the bat now connect the negative of the power supply to the negative of the bat leave it for 1 hr charge and check the bat voltage if no change or bat getting over heated then change the battery

Hey sir, first of all thank u but u got me wrong I want to use the Adapter to run the trimmer directly "without" using the battery, when I did that the motor was running fine outside the body of the trimmer but when I assembled the trimmer back again it didn't work properly, it almost doesn't work at all.
