12*V* Voltage
125*Ah* Capacity
760*A* Cold cranking
29.50*kg* Weight

The **Exide EG1251 truck battery** is rated at **12 V**, **125 Ah** and **760 A** of cold cranking current (EN) from the **Start PRO** range, and is prepared for trucks, buses, tractors and heavy machinery. Its 349 × 175 × 285 mm and the positive terminal on the left make it the exact replacement for the 125 Ah battery fitted as standard to many trucks.
- 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 Exide EG1251 is for

Designed for trucks, buses, tractors and heavy machinery, the Exide EG1251 withstands constant chassis vibration and discharges during stops with active loads. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 29.50 kg, EN taper post terminals and B0 hold-down.

### Dimensions, polarity and mounting

It has external dimensions of 349 × 175 × 285 mm and weighs 29.50 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. It uses a B0 hold-down and EN taper post terminals, the system that anchors and connects it in the vehicle. 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.

### Exide: the maker behind the EG1251

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. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty.

### The Exide EG1251: Start PRO range and conventional lead-acid technology

The **Start PRO** is the Exide range the EG1251 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.
In a conventional battery the electrolyte is liquid and the lead plates are immersed in it. It is a mature, economical and easily recycled technology, ideal for starting vehicles in normal use.

### Usage and maintenance tips

On batteries with filler caps, check the electrolyte level and top up only with distilled water. During rest stops with active loads, avoid repeated deep discharges: they shorten the life of any starter battery.

### Official warranty

The Exide EG1251 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 6:00 pm** 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 **14 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 is the Exide EG1251 battery installed in the vehicle?

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 our blog. 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 — with positive on the left 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.

### What is the service life of the EG1251 model?

Expected lifespan of the Exide EG1251 is 4 to 7 years in regular use (depends on technology and climate). 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 size is this battery?

Dimensions (length × width × height) are 349×175×285 mm — also written as 349x175x285 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.

### What polarity does the Exide EG1251 battery have?

Polarity: positive on the left. To identify it, place the battery in front of you with the terminals facing you and check which side the positive (+, marked with a red ring) is on. Before buying, verify the polarity matches your current battery: switching polarity forces longer cables or system reconfiguration, with short-circuit risk.

### Is the EG1251 valid for my vehicle?

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 EG1251 fits 210 verified vehicle versions in our database.

### Which batteries are equivalent to the Exide EG1251?

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.
