Advanced AGM Technology & QuadFlex Performance
The MotoBatt MB51814 utilizes advanced AGM (Absorbed Glass Mat) technology specifically engineered for demanding powersport applications. This high-density lead-acid battery eliminates common performance issues that affect standard motorcycle batteries, delivering consistent power when you need it most.
QuadFlex Technology Advantage: By reducing internal connection distance between battery cells and terminal posts, this battery delivers power more efficiently than conventional designs. This translates to faster engine cranking and improved performance, especially during cold starts when battery efficiency typically decreases.
The unique terminal configuration accommodates various connection types, making this battery suitable for motorcycles, ATVs, snowmobiles, and utility vehicles without requiring adapters or modifications to your existing setup.
Frequently Asked Questions
Will this battery fit my specific BMW motorcycle model?
This battery is designed as an exact replacement for all BMW models listed in our compatibility guide. The dimensions (7.2" × 3.15" × 6.69") match the original battery compartment precisely, ensuring proper fit without any modifications to your motorcycle.
How long will this AGM battery last compared to my original?
With proper maintenance and charging practices, AGM batteries typically provide 3-5 years of reliable service. The sealed design and advanced construction extend lifespan significantly compared to conventional flooded batteries, while eliminating maintenance requirements.
Can I use my existing battery charger with this AGM battery?
Yes, but ensure your charger is AGM-compatible and doesn't exceed the maximum charge rate of 1.3 amps. Most modern smart chargers automatically detect and adjust charging parameters for AGM batteries. Avoid old-style automotive chargers that may overcharge.
What makes the QuadFlex technology different from standard batteries?
QuadFlex technology shortens the internal connection paths between battery cells and terminals, reducing resistance and improving power delivery speed. This results in faster cranking, better cold weather performance, and more consistent power output compared to conventional battery designs.
Do I need any special tools for installation?
No special tools required. The included stainless steel screws, brass terminals, and spacers provide everything needed for installation. Basic hand tools (screwdriver, wrench) are sufficient for most installations. Terminal configuration adapts to various connection styles.
