Tudor TX1803 · Truck battery 12V 180Ah 1000A EFB

Truck battery Tudor TX1803 Super Heavy Duty EFB 180Ah 1,000A 12V

The Tudor TX1803 with EFB technology delivers 180 Ah at 12 V and 1,000 A of cold cranking current (EN): what trucks, buses, tractors and heavy machinery demand. It replaces the original battery without adaptation in trucks with a 513 × 223 × 223 mm format: same 180 Ah capacity and the positive terminal on the left.

In short: the Tudor TX1803 (180 Ah, 1000 A, 513 × 223 × 223 mm, positive terminal on the left). Verified equivalent alternatives: Exide EX1803 and Tudor TE1853.

• EFB technology: reinforced electrolyte for many more start cycles.
• Heavy Duty construction for intensive professional use.
• Powerful cold cranking for large-displacement diesel engines.
• Designed for 24 V installations with two batteries in series.

What the Tudor TX1803 is for

The Tudor TX1803 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 46.10 kg.

Will it fit your current battery tray?

In terms of format, the Tudor TX1803 measures 513 × 223 × 223 mm (length × width × height) and weighs 46.10 kg. The positive terminal on the left decides which side the cables end up on: it is the detail that causes most buying mistakes, so check it before ordering. 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.

Why choose Tudor batteries

Tudor is Spain's historic battery brand, today part of the Exide group. Its car, truck, motorcycle and leisure ranges are built with the same technology and controls as the group's original-equipment references. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty.

The Tudor TX1803: Super Heavy Duty EFB range and EFB technology

Within the Tudor catalogue, the Super Heavy Duty EFB series groups the references designed for this use. The TX1803 is the 180 Ah model of that family, with the same performance as its siblings in other sizes.

An EFB is a reinforced flooded battery: its plates retain the active material better and tolerate the cycling imposed by a simple Start-Stop system, at a lower cost than an AGM.

Usage and maintenance tips

During rest stops with active loads, avoid repeated deep discharges: they shorten the life of any starter battery. In 24 V installations, check periodically that both batteries show the same voltage; an imbalance means one is failing.

Warranty and coverage

The Tudor TX1803 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.

Delivery times 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.
