in this video i am going to show you how you can put a rechargeable battery inside your digital multimeter at home easily, i have my Mastech MAS830L Multimeter any you can try this procedure in any multimeter which have 9 volts battery, in this video i am using 2x 3.7 Volts full charged little rechargeable battery, you can also use 2 mobile battery, you just need greater than 7.5 Volts and lower than 9.5 Volts, full charge your 3.7 volts battery because its charge upto 4.2 Volts and you need minimum 7.5 Volts, when you connect 2 battery in series u will get 8.4 volts, and your multimeter works perfectly on this volts.
Now for charging you can use any 9 volt adaptor do not use 12 Volts adaptor, because 8.5 volts is good charging voltage for this battery.
