APC Cell Wiring Diagram

Purpose: When an APC battery backup's battery dies, you can manually replace the cells and 'refurbish' the battery. The following diagram is how you rewire the cells.

    %% Define cells and connections
    Cell1["Cell 1<br>Black (Negative) to Black (Negative)"] -.-> AndersonNeg["Anderson Connector Negative<br>(Black)"]
    Cell1 -->|"Red (Positive) to Black (Negative)"| Cell2["Cell 2<br>Red (Positive) to Black (Negative)"]
    Cell2 -->|"Red (Positive) to Black (Negative)"| Cell3["Cell 3<br>Red (Positive) to Black (Negative)"]
    Cell3 -->|"Red (Positive) to Fuse"| Fuse["30A Fuse"]
    Fuse -->|"Red (Positive) to Black (Negative)"| Cell4["Cell 4<br>Red (Positive) to Black (Negative)"]
    Cell4 -->|"Red (Positive) to Anderson Connector Positive"| AndersonPos["Anderson Connector Positive<br>(Red)"]

    %% Define styles
    classDef battery fill:#f2f2f2,stroke:#000,stroke-width:2px;
    class Cell1,Cell2,Cell3,Cell4 battery;

    classDef fuse fill:#ffcc00,stroke:#000,stroke-width:2px;
    class Fuse fuse;

    classDef anderson fill:#00ccff,stroke:#000,stroke-width:2px;
    class AndersonPos,AndersonNeg anderson;

    classDef positive fill:#ff0000,stroke:#000,stroke-width:2px;
    class AndersonPos positive;

    classDef negative fill:#000000,stroke:#fff,stroke-width:2px;
    class AndersonNeg negative;

    %% Define line colors for clarity
    linkStyle 0 stroke:#000,stroke-width:2px; 
    linkStyle 1 stroke:#ff0000,stroke-width:2px; 
    linkStyle 2 stroke:#ff0000,stroke-width:2px; 
    linkStyle 3 stroke:#ff0000,stroke-width:2px; 
    linkStyle 4 stroke:#ff0000,stroke-width:2px; 
    linkStyle 5 stroke:#ff0000,stroke-width:2px;
