The **Exide EG1203 truck battery** is rated at **12 V**, **120 Ah** and **680 A** of cold cranking current (EN) from the **Start PRO** range, and is prepared for trucks, buses, tractors and heavy machinery. Measuring 513 × 189 × 223 mm, it is the direct replacement for trucks fitted from the factory with a 120 Ah battery of this format.
- Powers tachograph, fridge and heater during rest stops.
- Better tolerance to deep discharge than a conventional starter battery.
- Good balance of capacity, cranking power and price.
- Resistant to constant chassis vibration.

### Vehicles compatible with the Exide EG1203

This battery appears as compatible in more than 720 vehicles from manufacturers such as Fiat, Volvo, Deutz-Fahr, John Deere, Fendt and Komatsu. For anyone who needs to replace the **battery in their Fiat** or Volvo, this Exide EG1203 reproduces the original specifications. The compatibility list also includes models from Claas, Khd, Gueldner, Case, Bührer, Caterpillar, Bourgoin and Stavostroj. It covers 25 original-equipment references, one of the widest coverages in its format.

### Dimensions, polarity and mounting

In terms of format, the Exide EG1203 measures 513 × 189 × 223 mm (length × width × height) and weighs 32.50 kg. Before replacing it, measure your current battery tray: if all three dimensions and the terminal positions match, the swap is direct and needs no adapters.

### What Exide does differently

Exide is one of the world's largest battery manufacturers and an original-equipment supplier to many car makers. Its European plants produce starter, industrial and leisure batteries under original-equipment quality controls. All the Exide batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty.

### The Exide EG1203: Start PRO range and conventional lead-acid technology

The EG1203 is part of the Exide **Start PRO** 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.

### 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 Exide EG1203 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

Orders placed **before [[ks:cutoff]]** with the battery in stock ship the same day. Delivery in mainland Spain and Portugal takes 24-48 working hours; for the Balearic Islands and the rest of the European Union allow 3 to 5 working days. You have **[[ks:return_days]] days** to return an unused battery; in mainland Spain and Portugal collection is free. We email you the tracking number as soon as the parcel ships.

## Frequently asked questions

### How do I change this battery step by step?

In most trucks it fits in 15-30 minutes with a 10 mm wrench; if the battery is under the seat or in the boot the time can double. See the step-by-step guide on this page. Quick summary: 1) switch off the engine and remove the key; 2) locate the original battery (engine bay, boot or under seat); 3) disconnect the negative (−) terminal first, then the positive (+); 4) loosen the hold-down clamp and remove the old battery; 5) fit the new one in the same orientation — match the polarity shown on the product sheet; 6) connect the positive (+) first, then the negative (−). On trucks with Start-Stop or BMS, register the battery via OBD so the alternator applies the correct charging profile.

### How many years does this battery last?

Expected lifespan of the Exide EG1203 is 4 to 6 years in regular truck use without Start-Stop. In cold regions it drops slightly due to cold-start stress; in very hot regions it also drops because of electrolyte evaporation. To extend its life: avoid deep discharges (headlights on with engine off), have the alternator checked yearly, and keep the battery clean and properly secured.

### What are the dimensions of the Exide EG1203 battery?

Dimensions (length × width × height) are 513×189×223 mm — also written as 513x189x223 mm — following the European DIN standard. Always measure the space in your truck before buying: even one extra millimetre can prevent the hold-down clamp from closing. The height shown includes the terminals.

### Will the Exide EG1203 battery fit my truck?

Three options to confirm: 1) enter your number plate in the finder (DGT/DVLA/KBA auto-detect your model and engine); 2) check the "Compatible vehicles" tab on this page, where we list every vehicle verified by our technical team; 3) if you cannot find your model, message us on WhatsApp with brand, model, engine and year — we reply during business hours (Mon–Fri 10:00–13:30 and 16:40–18:00 (Spanish time, CET)). The EG1203 fits 360 verified vehicle versions in our database.

### Which batteries are equivalent to the Exide EG1203?

Directly interchangeable batteries (same dimensions, same polarity, same Ah and CCA) are the OEM equivalents from leading brands: Bosch, Tudor, Exide and, depending on the model, Banner or Yuasa. Exact equivalence depends on technology — an EFB cannot be replaced with a conventional battery in Start-Stop trucks. See the "Equivalents" section to view recommended options at the same performance level.
