Larger-capacity motorcycle applications demand a battery that can deliver sustained cranking power without sacrificing long-term reliability. The Numax NTS20LBS is a 12V, 20Ah AGM factory-sealed motorcycle battery rated at 270 CCA (EN), designed to meet those demands across a broad range of mid-to-large displacement bikes and powersports applications.
Built on Absorbent Glass Mat technology, the NTS20LBS immobilises the electrolyte within a fibreglass mat separator, eliminating free acid, enabling spill-proof operation, and providing superior resistance to vibration-induced plate damage. The factory-sealed construction means no acid filling is required prior to fitment – the battery arrives ready to install. Numax's motorcycle range is engineered to deliver dependable cold-weather cranking and consistent charge acceptance across everyday riding conditions.
The battery measures 175 mm × 87 mm × 155 mm (L × W × H) and weighs 6 kg. Terminal type is 2, with polarity code 0 and hold-down reference B00. No cross-reference codes are currently listed; buyers should verify fitment against OEM battery dimensions and CCA requirements. The product label should be consulted to confirm start-stop system compatibility, as the AGM technology supports such applications subject to vehicle-specific verification.
The NTS20LBS forms part of the broader Numax motorcycle battery range, which spans an extensive selection of case sizes and capacities. Related variants within the range include NTS12AA, NTS12ABS, NTS12B4, NTS12BS, NTS14AA2, NTS14B4, NTS14BS, NTS14LA2, NTS16BS, and NTS4LB, among others.
This battery is covered by a 1-year manufacturer warranty, providing assurance of reliable service life under normal operating conditions.
Standard delivery: 1–3 working days within UK mainland. 30-day returns.
