Enhanced Long Life Battery System

This paper presented an Enhanced Long-Life Bat-tery System that combines a Lithium Primary Battery, MCP1700 Low-Dropout Voltage Regulator, Arduino Nano, and low-power sleep-mode programming to re-duce energy consumption and extend battery life. Ex-perimental results demonstrated stable operation and improved power efficiency. The proposed system is compact, economical, and suitable for embedded and IoT applications where long battery life is essential.
