Smaller-displacement motorcycles and scooters demand a battery that delivers reliable cold cranking performance within a compact footprint, without requiring pre-activation. The Numax NTS4LBS is a 12V 4Ah AGM factory-sealed motorcycle battery designed to meet that requirement directly from the box, with no acid filling or initial charging required before fitment.
Manufactured using Absorbent Glass Mat technology, the NTS4LBS immobilises the electrolyte within a fibreglass separator, eliminating free acid, reducing internal resistance, and enabling superior charge acceptance compared with conventional flooded motorcycle batteries. The factory-sealed construction means the battery arrives fully charged and maintenance-free." The NTS4LBS measures 113mm (L) × 69mm (W) × 85mm (H including terminal) and weighs 1.41 kg. It delivers 50 CCA (EN) and uses a Type 2 terminal configuration with polarity code 0 and hold-down classification B00. No cross-reference codes are supplied; buyers should verify fitment against their vehicle's battery specification before ordering. The technology supports start-stop systems – confirm compatibility on the product label. "This battery is part of the Numax Motorcycle range, which covers an extensive selection of sizes. Related variants available within the range include NTS12AA, NTS12ABS, NTS12B4, NTS12BS, NTS14AA2, NTS14B4, NTS14BS, NTS14LA2, NTS16BS, and NTS20LBS." The NTS4LBS is covered by a 1-year warranty against manufacturing defects under normal operating conditions. "Standard delivery: 1–3 working days within UK mainland. 30-day returns.

A. AGM stands for Absorbent Glass Mat. The electrolyte is held within a fibreglass separator rather than being free liquid. This eliminates acid spillage risk, reduces internal resistance, improves charge acceptance, and makes the battery maintenance-free — advantages particularly relevant for motorcycles with limited battery access.
