Yuasa N-65 / 75B24L EFB (12V 50Ah 500A)

The Hybrid & Start-Stop Essential. Made in Japan for Urban Efficiency.

The “N-65” code represents the Enhanced Flooded (EFB) upgrade over the standard B24 size. This Japanese-made unit is the preferred Original Equipment (OE) replacement because it handles the unique power demands of vehicles that shut off the engine at every traffic light.

✨ Key 2026 Technical Features

• ⚡ Lithium-Carbon Technology:

  The electrolyte is infused with lithium carbon to improve charge acceptance by up to 50%. This ensures the battery recharges quickly during short city trips, keeping the start-stop system active even in heavy Singapore traffic.

• 🔄 2x Cycling Performance:

  Engineered to handle twice the charge/discharge cycles of a conventional battery. This durability is vital for the Honda i-DCD hybrid system and Mazda i-Stop, where the battery must power electronics while the engine is off.

• 🏗️ Reinforced Plate Design:

  Features thicker internal components and a “High-Density Active Material” that provides superior vibration resistance. This prevents the internal damage often caused by Singapore’s many speed bumps and uneven road surfaces.

• 🌡️ Heat-Resistant Alloy:

  Specifically designed for hot tropical climates, the lead-calcium-tin alloy grid minimizes water loss and internal corrosion. This helps maintain a service life of 18–24 months despite the extreme heat of a cramped engine bay.

• 🛑 Direct OE Replacement:

  This is a “plug-and-play” solution for Japanese makes. It fits perfectly into the original battery tray and ensures the car’s Battery Management System (BMS) recognizes the correct charging profile immediately.
