Batteries play a crucial role in ensuring uninterrupted connectivity, providing backup power during outages or in locations without reliable electricity. In networking, batteries are used to power wireless access points, routers, and other critical infrastructure, maintaining essential services even when mains power is unavailable. Choosing the right battery involves considering factors like capacity, voltage, and rechargeability to meet the specific requirements of the network setup. By integrating reliable batteries into their systems, network operators can enhance the resilience of their infrastructure, ensuring continuous connectivity and minimizing downtime for users.
