Fulmen FG1406 StartPRO · Truck battery 140Ah 800A

Truck battery Fulmen FG1406 StartPRO 140Ah 800A 12V

The Fulmen FG1406 with conventional lead-acid technology delivers 140 Ah at 12 V and 800 A of cold cranking current (EN): what trucks, buses, tractors and heavy machinery demand. Its 510 × 175 × 225 mm and the positive terminal on the right make it the exact replacement for the 140 Ah battery fitted as standard to many trucks.

In short: the Fulmen FG1406 (140 Ah, 800 A, 510 × 175 × 225 mm, positive terminal on the right). Verified equivalent alternatives: Tudor TG1406 and Exide EG1406.

• Better tolerance to deep discharge than a conventional starter battery.
• Powers tachograph, fridge and heater during rest stops.
• Resistant to constant chassis vibration.
• Good balance of capacity, cranking power and price.

Will it fit your current battery tray?

In terms of format, the Fulmen FG1406 measures 510 × 175 × 225 mm (length × width × height) and weighs 33.50 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 B03 hold-down and 1 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.

What the Fulmen FG1406 is for

The Fulmen FG1406 is designed for trucks, buses, tractors and heavy machinery. In 24 V installations with two batteries in series, replace both at the same time to avoid imbalance. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 33.50 kg, 1 terminals and B03 hold-down.

The Fulmen FG1406: StartPRO range and conventional lead-acid technology

The FG1406 is part of the Fulmen StartPRO range. Choosing the right reference within the series comes down to capacity, dimensions and terminals: technology and quality are common to the whole family.

Conventional lead-acid is the benchmark against which other technologies are compared: good cranking current, great tolerance to alternator charging and the best price per amp-hour.

Why choose Fulmen batteries

With more than a century of history, Fulmen offers complete ranges for cars, trucks, motorcycles and leisure with the industrial quality of the Exide group. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty.

Warranty and coverage

The Fulmen FG1406 comes with the manufacturer's official warranty against manufacturing defects. An important note for commercial vehicles: most trucks use two batteries connected in series (24 V installation). If you replace only one, the new battery works alongside the old one, which has already lost capacity; that imbalance shortens its life and the manufacturer may treat it as misuse. Always replace both at the same time.

Care and maintenance

Keep the terminals clean and tight and the battery firmly secured against chassis vibration. In 24 V installations, check periodically that both batteries show the same voltage; an imbalance means one is failing.

Shipping, delivery and returns

Same-day dispatch from our warehouse for in-stock orders placed before 6:00 pm: 24-48 working hours in mainland Spain and Portugal, 3 to 5 days in the islands and the rest of Europe. Returns are accepted for 14 days if the battery has not been used (free collection on the Iberian mainland). You will receive tracking by email.
