CRITICAL FACTORY CHARGING & POLARITY WARNING:
**Polatiry Verification:** This is a **"Left Hand Positive" (L-Style)** terminal layout where the positive (+) post is positioned on the front left corner when looking at the battery face. Before finalized installation, verify your original battery's terminal orientation; installing this battery backward will instantly fry your machine's master main fuse or wiring harness.
**Activation Note:** This is an unactivated dry AGM battery shipped with an enclosed precise acid pack. Prior to final installation, the battery must be filled, sealed permanently with the included flush cap strip, and charged using a proper smart AGM charger. Once sealed, it becomes completely spill-proof, leak-proof, and can be mounted at aggressive angles without fluid loss.
