Rated 5 out of 5

Original price was: KSh7,000.00.Current price is: KSh5,900.00.

Key Features

  • 100% Maintenance-Free Operation: Features a completely sealed, “fit-and-forget” design that eliminates the need for acid top-ups or checking electrolyte levels for the entire life of the battery.

  • 35Ah–40Ah High Performance: Specifically rated for small to mid-sized petrol vehicles, providing consistent power for essential electronics like alarms, radios, and central locking systems.

  • Strong Cold Cranking Power (300–400 CCA): Delivers a reliable burst of energy (typically 330A to 360A) for instant ignition, ensuring your car starts smoothly even on cold mornings or after days of inactivity.

  • Advanced Calcium-Calcium (Ca-Ca) Technology: Built with high-purity lead-calcium alloy plates that resist grid corrosion and minimize self-discharge, significantly extending the battery’s service life.

  • Tropicalized for Local Climates: Engineered with high heat resistance to prevent “thermal runaway” and battery swelling, making it perfect for the high-temperature driving conditions in Kenya.

  • Vibration and Shock Resistant: Housed in a reinforced, durable casing designed to withstand the mechanical stress of rough roads and off-road terrain without damaging internal components.

  • Integrated Safety Features: Equipped with a built-in flame arrestor to prevent external sparks from igniting internal gases and a central degassing system for maximum safety under the hood.

  • Visual Health Indicator (“Magic Eye”): Includes a built-in hydrometer that allows you to check the battery’s charge status and health at a glance without any tools.

  • Low Self-Discharge Rate: High-quality construction keeps the self-discharge rate below 3% per month, ensuring your vehicle remains ready for the road even if driven only occasionally.

  • Compact JIS Standard Fitment: Designed specifically for popular Japanese and European compact cars such as the Toyota Vitz, Passo, Probox, Nissan March, Honda Fit, and Mazda Demio.

Description

NS40 Sealed Maintenance-Free (SMF) Car Battery: Reliable Power for Compact Vehicles

The NS40 Maintenance-Free Car Battery is the go-to power solution for small to mid-sized petrol vehicles. Specifically engineered for the compact engine bays of Japanese and European salon cars, this battery combines high-performance starting power with a completely “fit-and-forget” design.

Utilizing advanced Calcium-Calcium (Ca-Ca) technology, the NS40 (also known in newer JIS codes as 36B20 or 40B19) is designed to deliver a high burst of energy for instant ignition while maintaining exceptional charge retention. As a Sealed Maintenance-Free (SMF) battery, it eliminates the need for acid top-ups, making it the perfect choice for busy urban drivers in Nairobi and beyond.

Why the NS40 Maintenance-Free Battery Stands Out

  • 100% Maintenance-Free: The sealed design features a built-in labyrinth system that traps evaporated electrolyte and returns it to the cells. You will never need to open the caps or add distilled water.

  • Strong Cranking Power: Despite its compact size, the NS40 delivers impressive Cold Cranking Amps (CCA)—typically between 330A and 370A—ensuring your car starts first time, every time, even after sitting idle for days.

  • Calcium-Calcium Longevity: The use of calcium alloy on both positive and negative plates reduces internal grid corrosion and minimizes water loss, extending the battery’s service life to 3–5 years with proper alternator care.

  • Vibration Resistance: Built for the realities of the road, the NS40 features a reinforced polypropylene casing that protects delicate internal plates from the mechanical shocks of rough terrain or speed bumps.

Product Highlights

1. Tropicalized for Extreme Heat

Kenyan driving conditions often involve high ambient temperatures and heavy traffic jams. The NS40 is tropicalized, meaning it is formulated with heat-resistant technology that prevents “thermal runaway” (swelling), a common cause of failure in standard batteries in hot climates like Mombasa or Kisumu.

2. Visual Health Indicator (“Magic Eye”)

Most premium NS40 models come equipped with a built-in hydrometer or “Magic Eye.” This allows you to check the battery’s health at a glance:

  • Green: Fully Charged

  • Black/White: Needs Charging

  • Red: Replacement Required

3. Low Self-Discharge

High-purity lead materials ensure that the NS40 loses very little charge when the vehicle is not in use. This makes it an ideal choice for occasional drivers or vehicles that stay parked for weeks at a time.

Ideal Applications: Which Cars Use the NS40?

The NS40 is the standard fitment for many of Kenya’s most popular fuel-efficient vehicles, including:

  • Toyota: Vitz, Passo, Probox, Corolla (older models), Belta, and Noah/Voxy (as an auxiliary).

  • Nissan: March, Note, Wingroad, and AD Van.

  • Honda: Fit, Airwave, Insight (Auxiliary), and Civic (older models).

  • Mazda: Demio and Verisa.

  • Suzuki: Swift, Alto, and Wagon R.
