Deka YT12B-BS AGM Motorcycle Battery
The Deka YT12B-BS is a 12V AGM powersport battery engineered for dependable starting in motorcycles and scooters requiring the 12B-BS Group size. Its absorbed glass mat (AGM) design delivers strong cranking performance with spill-proof, vibration-resistant construction. Rated at 210 CCA with 10Ah capacity, it’s a smart upgrade when you need an AGM motorcycle battery that holds up to real-world riding. This Deka powersport battery ships as a fresh pack (not factory-activated) for optimal shelf life and performance once properly filled and charged.
YT12B-BS Features:
- AGM Construction – Provides spill-proof safety and excellent vibration resistance for powersport use
- Bottle-Supplied Activation – Not factory activated; includes acid pack for proper fill and requires charging
- Group 12B-BS Case – Narrow profile fits OEM trays that call for 12B-BS
- Low Self-Discharge – Holds a charge longer between rides than flooded batteries
- Powersport Terminals – Top and front connection options ensure easy installation
- Left-Positive Polarity – Always verify your current battery's terminal locations
Note: The 12B-BS case is narrower than a standard 12-BS; this battery is not interchangeable with 12-BS sizes.
