Yuasa YBX3642 110Ah 925CCA Battery – Defender & Discovery 2

The Yuasa YBX3642 Super Heavy Duty is a premium commercial-grade starter battery for Land Rover Defender and Discovery 2 that work harder than just a run to the shops. Built on Yuasa’s experience in trucks, buses, agricultural machinery and plant equipment, this SHD battery is designed to cope with vibration, heavy electrical loads and tough duty cycles – exactly the sort of life a proper Land Rover leads.

With 110Ah capacity and 925CCA, the YBX3642 delivers strong, reliable cranking performance for 200Tdi, 300Tdi and Td5 engines, even in cold, damp conditions.

Why Yuasa for Defender & Discovery 2?

Yuasa is a well-known OE battery supplier in commercial, agricultural and industrial sectors. Their SHD (Super Heavy Duty) range is engineered for vehicles that earn their living – so it’s a natural fit for Land Rover owners who:

• Tow regularly or carry heavy loads
• Use their trucks off-road or on farms
• Run winches, work lights or extra electrical accessories
• Need dependable starting in all weathers

Compared with the typical 072/069 “car” batteries, this Yuasa SHD unit uses heavier plates and a more robust construction for much better vibration resistance, longer life and better recovery from repeated cold cranking.

Benefits for Td5 and Tdi Land Rovers

• Strong cold starting – 925CCA gives confident cranking in winter
• Commercial-grade durability – 3D grid design with V3 vibration resistance stands up to rough tracks and chassis vibration better than a typical car battery
• Low maintenance – sealed calcium technology and low self-discharge mean it will sit for days or weeks between uses
• OE-level quality – built to original equipment standards for performance and reliability

If you want a premium branded battery from a manufacturer trusted in industrial and agricultural sectors, the Yuasa YBX3642 is an excellent choice.
