NTX16BS Numax AGM AGM Motorcycle Battery With Acid Pack 12V 14Ah, 1 Year Warranty

Motorcycle batteries must endure repeated high-current discharge cycles, vibration, and temperature extremes that quickly degrade conventional flooded cells. The Numax NTX16BS addresses these demands as a sealed Absorbent Glass Mat (AGM) unit designed for reliable cold-start performance across a wide range of medium to large-displacement motorcycles. Supplied complete with an acid pack, it is ready to activate and fit without specialist tools or workshop equipment.

Numax engineers this battery using AGM technology, in which the electrolyte is suspended within a tightly compressed glass mat separator rather than held as free liquid. This construction eliminates acid stratification, reduces internal resistance, and provides the consistent 220 CCA (EN) output required to turn over higher-compression engines in cold conditions. The sealed, maintenance-free design also means no topping-up of electrolyte is required throughout its service life. The technology is confirmed to support start-stop system architectures, though fitment to start-stop vehicles should be verified against the product label before installation." The NTX16BS measures 150 mm 88 mm 161 mm (L W H including terminal) and weighs 4.91 kg. It operates at 12 V with a rated capacity of 14 Ah (C20) and 220 CCA (EN). The battery uses a Type 2 terminal configuration with polarity code 1 (positive terminal to the right when viewed from the front) and a B00 hold-down specification. It carries the cross-reference code YTX16-BS and is a direct equivalent replacement for batteries listed under that designation in OEM and aftermarket fitment guides. "The NTX16BS is one model within the broader Numax motorcycle AGM range. Alternative capacities and case sizes are available under SKUs including NTS12AA, NTS12ABS, NTS12B4, NTS12BS, NTS14AA2, NTS14B4, NTS14BS, NTS14LA2, NTS16BS, and NTS20LBS, covering a wide spectrum of motorcycle applications.

This battery is backed by a 1-year manufacturer warranty, providing cover against defects in materials and workmanship under normal operating conditions.
