the negative pole of cylindrical batteries is the smooth end.
The metallic element that serves as the negative pole in a common flashlight battery is zinc.
The negative electrode in a common flashlight battery is typically made of zinc.
The positive pole on the battery is the anode. The negative pole is the cathode.
Positive + and negative-
First you must disconnect the negative(-) pole, then disconnect the positive(+), connect the new battery begining with the positive(+) pole, then the negative one.
To get 24V from 2 12 V battery's Yo hook up the positive pole + of one of the battery's to the negative pole - of the other one. you will be left with a positive pole on each battery wit no connection on them The voltage between them is 24. If you want the battery to have the same voltage but have more amperage you connect positive to positive and negative to negative.
The battery ... without that it can't be a flashlight.
When the flashlight is turned on, electrons move from the negative terminal of the battery through the wires and components of the flashlight to the positive terminal. This movement of charges creates an electric current that powers the light bulb or LED in the flashlight, causing it to produce light.
Hi there is a red plastic on the 1 pole that is positive and a black plastic on the other that is the negative
