Fulmen FG1206 · Truck battery 12V 120Ah 680A

Truck battery Fulmen FG1206 StartPRO 120Ah 680A 12V

The Fulmen FG1206 truck battery is rated at 12 V, 120 Ah and 680 A of cold cranking current (EN) from the StartPRO range, and is prepared for trucks, buses, tractors and heavy machinery. Its 510 × 175 × 225 mm and the positive terminal on the right make it the exact replacement for the 120 Ah battery fitted as standard to many trucks.

In short: the Fulmen FG1206 (120 Ah, 680 A, 510 × 175 × 225 mm, positive terminal on the right). Verified equivalent alternatives: Tudor TG1406 and Exide EG1406.

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

What the Fulmen FG1206 is for

With 120 Ah, the Fulmen FG1206 cranks large-displacement diesel engines in the cold and powers tachograph, fridge and heater during rest stops. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 31.80 kg and B03 hold-down.

The Fulmen FG1206: StartPRO range and conventional lead-acid technology

The StartPRO is the Fulmen range the FG1206 belongs to: it shares the same construction and quality criteria with the rest of the series, and varies in capacity and format to suit each vehicle.

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.

Will it fit your current battery tray?

It has external dimensions of 510 × 175 × 225 mm and weighs 31.80 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, the system that anchors and connects it in the vehicle. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery.

What Fulmen does differently

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. All the Fulmen batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty.

Usage and maintenance tips

In 24 V installations, check periodically that both batteries show the same voltage; an imbalance means one is failing. On batteries with filler caps, check the electrolyte level and top up only with distilled water.

Warranty and coverage

The Fulmen FG1206 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.
