FREQUENTLY ASKED QUESTIONS

Q: How does the NLX31 compare to a traditional Group 31 lead-acid battery in real-world performance?
A: The NLX31 provides double the starting power (1600A vs ~800A), 2X more usable capacity, charges 20X faster, and lasts 20X longer than comparable lead-acid batteries. It also weighs nearly half as much (33 lbs vs 60+ lbs) and eliminates sulfation concerns that cause premature lead-acid failure.

Q: What is included in the complete accessory kit?
A: The NLX31 includes everything needed for installation: removable carrying handle, multiple terminal types (SAE posts, threaded terminals in various sizes), all necessary nuts and bolts, terminal covers and caps, hex keys, and complete documentation. This comprehensive kit ensures compatibility with virtually any Group 31 application.

Q: Can I use my existing Group 31 battery charger?
A: The NLX31 is compatible with most quality battery chargers, but for optimal performance and fastest charging, we recommend NOCO's lithium-compatible chargers. The battery can accept up to 120A charging current for 1-hour rapid recharge capability.

Q: How do the flexible terminal configurations work?
A: The NLX31 features both middle terminals (under the removable handle) and front terminals, allowing you to choose the most convenient connection points for your application. Use the included terminal covers to protect unused connections, and the various hardware options accommodate different cable types and connection preferences.

Q: What does the 5-year warranty cover?
A: NOCO provides a comprehensive 5-year limited warranty covering manufacturing defects and performance degradation. This industry-leading warranty reflects the exceptional quality and longevity of lithium iron phosphate technology compared to typical 1-2 year lead-acid warranties.
