NOVELTY - The device has a cell (100) including an electrical terminal (220). A circuit board (200) is electrically connected to the electrical terminal. A moisture resistant coating is provided on a portion of a surface of the cell and a surface of the circuit board, where the resistant coating is conformal, and creates a minigasket between the electrical terminal and the surface of the cell. The resistant coating does not store or retain charge. A lead plate (310) connects the cell to the circuit, where the moisture resistant coating covers a portion (312) of the lead plate.    USE - Energy storage device i.e. rechargeable battery such as lithium-ion battery, lithium- ion polymer battery, nickel-cadmium battery, and nickel- metal hydride battery, for storing electrical energy for use in a portable electronic device e.g. laptop computer, mobile electronic device such as cellular telephone, and smart phone, mobile computing device such as tablet computing device, digital media player, personal digital assistant (PDA) device, camera, portable electronic accessory such as wireless headphone, wireless headset, mobile speaker, wireless keyboard, and wireless mouse. Can also be used for a fuel cell, ultra capacitor, super capacitor, electrochemical capacitor, battery/capacitor hybrid, and zinc air battery for electric vehicle and equipment, gaselectric hybrid vehicle and equipment, power tool, gardening tool, and exercise equipment and a toy.    ADVANTAGE - The moisture resistant coating prevents moisture from contacting electrical couplings between the cell and the circuit board, and limits or prevents exposure of other electrical components of the circuit board and the cell to moisture, thus protecting the components of the device from external influences in an efficient manner.
