YTX14AHL-BS Lithium Battery Replacement (LiFePO4)
The YTX14AHL-BS Lithium Battery Replacement is a premium upgrade designed to outperform traditional lead-acid and AGM batteries. Built with advanced LiFePO4 (Lithium Iron Phosphate) technology, this battery provides higher starting power, faster charging, and a significantly longer lifespan. Not Yuasa brand.
Perfect for motorcycles, ATVs, UTVs, scooters, and personal watercraft, this lightweight lithium battery ensures reliable performance and consistent power delivery in all conditions.
🔋 Lithium Power Advantage
Unlike traditional batteries, lithium technology delivers more usable energy with less weight. Even with a lower amp-hour rating, it provides equivalent or better performance.
- Capacity: 12Ah PbEq (Lead-Acid Equivalent)
- Actual Capacity: ~5Ah Lithium
- Cycle Life: 2000+ cycles
- Weight Reduction: Up to 70% lighter
Lithium batteries require less amp-hour capacity to deliver the same starting performance as traditional lead-acid batteries.
⚡ High Performance Starting Power
- Strong cold cranking amps (CCA) for reliable starts
- Fast recharge capability
- Low self-discharge for seasonal storage
- Consistent voltage output
🛠️ Easy Installation
This battery is designed as a direct replacement for YTX14AHL-BS and installs quickly with standard terminal connections. No modifications required.
