Overlapping Batteries
A Button lithium battery is shaped as shown below. It has exposed positive and negative metallic surfaces with a thin cylindrical seal, called the gasket, in between. When batteries are overlapped or mixed together in a disorder way, their positive and negative terminals touch each other, causing short circuits.
Batteries put in a Metallic Container or on a Metallic Plate
Similar to the overlapping battery problem, when batteries are put in a metallic container or on a metallic plate, their positive and negative terminals may short circuit through the conductive surface depending on the placement
When a Battery is Held with Tweezers
When held with a pair of metallic tweezers as shown below, the battery short-circuits through the tweezers
When Battery Lead Plates Touch Each Other
When battery lead plates bend and touch each other or either terminal, the battery short-circuits.
Solder Bridges
Solder may bridge between board conductors, short-circuiting and draining battery.
Short-circuited though Soldering Iron
Similar to solder bridging, when the circuit board wiring is short-circuited by a soldering iron for an extended period, the battery is drained and consumed. Complete manual soldering within 5 seconds.
Shorts through Piled Circuit Board
When circuit boards with batteries are piled on top of one another, their conductive traces may touch, and form a battery discharge circuit that consumes the battery's power. 8 Document Outline EEMB CO., LTD Specification Battery Structure Scope Features and Applications Battery Basic Characteristics Performance and Test Methods Characteristics Curve Matters Needing Attention !
