Its dimensions are 4.40 x 2.90 x 3.42 inches, with polarity Negative on the left and Positive on the right. It’s a maintenance-free unit suitable for smaller displacement bikes or an auxiliary battery setup, designed to deliver reliable starts in a compact form.
Buying Guide
- Battery chemistry: AGM SLA batteries are sturdy and maintenance-free, offering good vibration resistance and spill-proof design, while lithium variants like NLP20 and TYKOOL offer lighter weight and higher power-to-weight ratios but may require different charging considerations.
- Cranking amps vs. capacity: For cold starts, higher CCA improves reliability in cold climates. For weight-sensitive builds, lithium options can reduce overall bike weight significantly.
- Fit and polarity: Confirm case dimensions and terminal locations match your bike’s battery tray and wiring harness. Incorrect fit can lead to improper mounting or grounding issues.
- Weight: Lighter lithium batteries reduce unsprung weight and may improve handling, but ensure the vehicle’s electrical system supports lithium charging profiles.
- Maintenance and charging: AGM/SLA batteries require less maintenance but a proper charger is still recommended. Lithium batteries often include smart BMS features and may require a compatible charger.
- Durability and runtime: Consider climate and vibration exposure. AGM designs excel in broad temperatures, while lithium units maintain consistent performance and cycle life when properly managed.
- Compatibility: Verify that the selected battery is compatible with your motorcycle model, including group size, voltage, and mounting orientation.
