Motorcycle batteries operate in demanding conditions subjected to vibration, temperature extremes, and the high discharge demands of modern ignition systems. The Numax NTS12AA is a factory-sealed AGM (Absorbent Glass Mat) motorcycle battery rated at 12V and 12Ah, designed to deliver reliable cold-weather starting and maintenance-free service across a wide range of bike applications.
Manufactured by Numax Batteries, the NTS12AA uses AGM technology in which the electrolyte is immobilised within a fibreglass mat separator. This construction eliminates free acid, prevents spillage, and supports the high-vibration environment typical of motorcycle use. The sealed, recombinant design means no topping-up is required and no acid pack need be added prior to fitment the battery arrives ready to install.
The NTS12AA measures 134mm (L) 80mm (W) 161mm (H) and weighs 4.35kg. Cold Cranking Amps (EN) are rated at 160A, providing sufficient starting current for mid-range single and parallel-twin motorcycle engines. The battery uses a standard Type 2 terminal configuration with positive polarity code 1 (positive terminal to the left when viewed from the front). Hold-down type is B00. No cross-reference codes are currently listed; buyers should verify fitment against OEM specifications before ordering.
The NTS12AA is part of Numax's extensive motorcycle battery range. Related variants within the same family include the NTS12ABS, NTS12B4, NTS12BS, NTS14AA2, NTS14B4, NTS14BS, NTS14LA2, NTS16BS, NTS20LBS, and NTS4LB, covering a broad spread of capacities and case sizes." This battery is covered by a 1-year manufacturer's warranty against defects in materials and workmanship under everyday operating conditions. "Standard delivery: 13 working days within UK mainland. 30-day returns.

A. Yes. The NTS12AA is a factory-sealed AGM battery. The electrolyte is permanently immobilised within the AGM separator at the point of manufacture, so no acid pack is required and the battery can be installed directly without any pre-activation steps.
A. The NTS12AA measures 134mm in length, 80mm in width, and 161mm in height (including terminals). It weighs 4.35kg. Always confirm these dimensions against your battery compartment specification before ordering.
A. The NTS12AA uses a Type 2 terminal configuration. Polarity code is 1, meaning the positive terminal is positioned to the left when the battery is viewed from the front. The hold-down type is B00. Verify terminal positions match your motorcycle's wiring layout before fitment.
A. AGM technology is generally compatible with start-stop applications. However, Numax advises that start-stop suitability should be verified against the product label and the vehicle manufacturer's specification. Do not fit this battery to a start-stop system without first confirming compatibility.
A. No cross-reference codes are currently listed for the NTS12AA. To confirm a direct replacement, compare the voltage (12V), capacity (12Ah), CCA rating (160A), and physical dimensions (134 80 161mm) against your existing battery or OEM specification.
A. The NTS12AA is covered by a 1-year manufacturer's warranty against defects in materials and workmanship under normal everyday operating conditions. The warranty does not cover damage resulting from incorrect fitment, improper charging, or physical misuse.
A. The Numax motorcycle battery range includes a wide variety of case sizes and capacities. Variants related to the NTS12AA include the NTS12ABS, NTS12B4, NTS12BS, NTS14AA2, NTS14B4, NTS14BS, NTS14LA2, NTS16BS, NTS20LBS, and NTS4LB. If the NTS12AA does not match your fitment requirements, one of these alternatives may be appropriate.
A. No. As a sealed AGM battery, the NTS12AA is entirely maintenance free. There are no vent caps to check, no electrolyte levels to monitor, and no distilled water to add. The recombinant cell design prevents gas from escaping under normal operating conditions.
A. The NTS12AA is dispatched via standard parcel service. Delivery to UK mainland addresses takes 13 working days. A 30-day returns policy applies. For full terms, including any restrictions on used or installed batteries, please refer to the PartsForMachines returns policy at the time of purchase.
A. The NTS12AA is rated at 160 Cold Cranking Amps (CCA) to the EN standard. This represents the discharge current the battery can sustain for 30 seconds at −18°C while maintaining a voltage above 7.5V, and indicates its cold-weather starting capability.
