High-displacement motorcycle engines demand a battery capable of delivering substantial cold cranking power without compromising cycle life or maintenance requirements. The Numax NTX20LBS is a 12V 18Ah AGM motorcycle battery supplied complete with an acid pack, designed to meet the cranking and standby demands of larger-capacity bikes where reliability at first turn is non-negotiable.
Built on absorbent glass mat technology, the NTX20LBS immobilises the electrolyte within tightly compressed glass fibre separators. This construction eliminates free acid, enables spill-proof operation in any orientation, and delivers low internal resistance for strong, sustained cranking performance. With a cold cranking amp rating of 250A (EN), the battery provides the starting authority required across a wide range of ambient temperatures.
The NTX20LBS measures 175mm 87mm 154mm (LWH inc. terminal) and weighs 5.86kg. It carries a Type 2 terminal configuration with B00 hold-down and standard polarity (positive terminal left, Polarity 0). It is a direct replacement for the widely referenced YTX20L-BS fitment code. Note that this technology supports start-stop systems; verify compatibility with the product label before fitment.
The NTX20LBS is part of the broader Numax motorcycle battery range, available across multiple case sizes and terminal configurations including NTS12AA, NTS12B4, NTS14BS, NTS16BS, and NTS20LBS among others providing coverage across a wide spectrum of motorcycle applications." This battery is backed by a 1-year warranty covering defects in materials and workmanship under normal operating conditions. "Standard delivery: 13 working days within UK mainland. 30-day returns.
NUMAX motorcycle batteries offer great performance at a budget price. The range is vast covering almost every size of bike battery ever made. Each NUMAX motorcycle battery comes complete, either with an acid pack or factory sealed.

A. The NTX20LBS is a 12V battery with a rated capacity of 18Ah (C20) and a cold cranking amp (CCA EN) rating of 250A, making it suitable for larger-displacement motorcycle engines.
A. The NTX20LBS is a direct replacement for the YTX20L-BS fitment code, which is widely referenced across a range of cruiser, touring, and large-capacity sport motorcycles.
A. The battery measures 175mm (length) 87mm (width) 154mm (height including terminal) and weighs 5.86kg.
A. The NTX20LBS uses a Type 2 terminal configuration with a B00 hold-down bracket type. Polarity is standard (Polarity 0), with the positive terminal positioned on the left when viewed from the front.
A. The NTX20LBS is supplied complete with an acid pack. The electrolyte must be filled prior to first use in accordance with the instructions provided with the battery.
A. AGM (absorbent glass mat) technology immobilises the electrolyte within compressed glass fibre separators, resulting in a spill-proof, maintenance-free construction. This reduces internal resistance, supports reliable cold-weather starting, and extends cycle life compared with conventional flooded batteries.
A. The AGM technology used in the NTX20LBS supports start-stop operation; however, compatibility with a specific vehicle's start-stop system should always be verified against the product label and the motorcycle manufacturer's specification before fitment.
A. The NTX20LBS is covered by a 1-year warranty against defects in materials and workmanship under normal operating and charging conditions.
A. Yes. The Numax motorcycle AGM range includes multiple variants such as the NTS12AA, NTS12B4, NTS14BS, NTS16BS, and NTS20LBS, covering a wide range of case sizes and terminal configurations for different motorcycle applications.
