How dell 1691p batteries work?

DELL 1691p batteries have a negatively charged terminal and a positively charged terminal. In the dell 1691p battery, energy from electrochemical reactions causes electrons (negatively charged particles) to collect at the battery's negatively charged pole. Charged particles are attracted to opposite charge, so if you connect a battery to a circuit, the electrons will flow from the negative pole, through the circuit and to the battery's positively charged pole. In other words, the battery generates a moving charge, or electricity.
