Car battery Exide EA406 Premium 40Ah 350A 12V

The Exide EA406 car battery is rated at 12 V, 40 Ah and 350 A of cold cranking current (EN) from the Premium range, and is designed for passenger cars with conventional starting, without a Start-Stop system.

In short: the Exide EA406 (40 Ah, 350 A, 187 × 127 × 220 mm, positive terminal on the right). It is a conventional battery for cars without Start-Stop: if yours has Start-Stop, it needs an EFB or AGM battery of the same size. Verified equivalent alternatives: Exide EA386 and Tudor TA406.

• Stable voltage for the vehicle electronics (ECU, sensors, climate control).
• Good balance of capacity, cranking power and price.
• Designed to last several years under normal daily use.
• Low self-discharge: copes with long stops without losing charge.

What the Exide EA406 is for

Designed for passenger cars with conventional starting, without a Start-Stop system, the Exide EA406 is the direct replacement when your vehicle uses a 40 Ah battery of this format. Before buying, compare dimensions, terminals and capacity with the battery you are replacing. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 9.90 kg, JIS terminals and B1 hold-down.

Will it fit your current battery tray?

In terms of format, the Exide EA406 measures 187 × 127 × 220 mm (length × width × height) and weighs 9.90 kg. The positive terminal on the right decides which side the cables end up on: it is the detail that causes most buying mistakes, so check it before ordering. It uses a B1 hold-down and JIS terminals, the system that anchors and connects it in the vehicle. For a direct replacement, the current battery tray must accept these dimensions and the same terminal layout; otherwise adapters will be needed or the hold-down will change.

The Exide EA406: Premium range and conventional lead-acid technology
