The absence of batteries in embedded tablets is typically due to several considerations:

Stability and Safety: Embedded systems often require continuous operation without mobility or charging needs, enhancing system stability and safety. Batteries can introduce safety concerns like overheating, charging issues, and battery lifespan concerns.

Cost Savings: Batteries are a crucial component in mobile devices, but for embedded applications, omitting batteries can significantly reduce manufacturing costs.

Lower Maintenance Costs: Batteries have a limited lifespan and require periodic replacement. In embedded systems, the absence of batteries reduces maintenance costs and ensures long-term system reliability.

Steady Power Supply: Embedded systems are typically powered through a stable external power source, contributing to system stability and reliability.

In summary, the exclusion of batteries in embedded tablets is aimed at improving system stability, safety, cost-efficiency, and reducing maintenance complexity. This makes them an ideal choice for applications that require continuous operation and fixed installation, such as automation systems, embedded controls, and smart homes.
