Deta DF1250 · Truck battery 12V 125Ah 850A

Truck battery Deta DF1250 PowerPRO 125Ah 850A 12V

The Deta DF1250 truck battery is rated at 12 V, 125 Ah and 850 A of cold cranking current (EN) from the PowerPRO range, and is prepared for trucks, buses, tractors and heavy machinery. Its 349 × 175 × 285 mm and the positive terminal on the right make it the exact replacement for the 125 Ah battery fitted as standard to many trucks.

In short: the Deta DF1250 (125 Ah, 850 A, 349 × 175 × 285 mm, positive terminal on the right). Verified equivalent alternatives: Varta J1 and Tudor TF1420.

• 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.

What the Deta DF1250 is for

The Deta DF1250 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 31 kg and B00 hold-down.

Size, terminals and hold-down of the Deta DF1250

In terms of format, the Deta DF1250 measures 349 × 175 × 285 mm (length × width × height) and weighs 31 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 B00 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 Deta does differently

Deta combines German engineering with Exide's industrial capacity. Its Power, Senator and PowerPRO series cover everything from urban cars to construction machinery. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty.

The Deta DF1250: PowerPRO range and conventional lead-acid technology

The PowerPRO is the Deta range the DF1250 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.

How to make it last longer

Keep the terminals clean and tight and the battery firmly secured against chassis vibration. On batteries with filler caps, check the electrolyte level and top up only with distilled water.

Warranty and coverage

The Deta DF1250 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.
