With **74 Ah** at **12 V** and **680 A** of cold cranking current (EN), the **Deta DB740** from the **Power** range is a starter battery built for passenger cars with conventional starting, without a Start-Stop system. Its 278 × 175 × 190 mm and the positive terminal on the right make it the exact replacement for the 74 Ah battery fitted as standard to many cars.
- Stable voltage for the vehicle electronics (ECU, sensors, climate control).
- Good balance of capacity, cranking power and price.
- Designed to last several years under normal daily use.
- Low self-discharge: copes with long stops without losing charge.

### What the Deta DB740 is for

Designed for passenger cars with conventional starting, without a Start-Stop system, the Deta DB740 is the direct replacement when your vehicle uses a 74 Ah battery of this format. Before buying, compare dimensions, terminals and capacity with the battery you are replacing. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 16.60 kg and B13 hold-down.

### Dimensions, polarity and mounting

It has external dimensions of 278 × 175 × 190 mm and weighs 16.60 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 B13 hold-down, 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.

### The Deta DB740: Power range and conventional lead-acid technology

The DB740 is part of the Deta **Power** range. Choosing the right reference within the series comes down to capacity, dimensions and terminals: technology and quality are common to the whole family.
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.

### Deta: the maker behind the DB740

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.

### Warranty and coverage

The Deta DB740 comes with the **manufacturer's official warranty** against manufacturing defects; the exact period is stated in the brand's conditions. If it fails through a defect within the period, we replace it free of charge.

### Usage and maintenance tips

Avoid leaving lights or accessories on with the engine off: most batteries fail not through defects but through repeated deep discharges. In normal daily use the alternator keeps the battery charged; if the car stands for weeks, a maintenance charge once a month prevents deep discharge.

### Delivery times and returns

Order **before [[ks:cutoff]]** with stock available and it leaves today: mainland Spain and Portugal receive it in 24-48 working hours, the islands and the rest of the EU in 3 to 5 days. You have **[[ks:return_days]] days** to return it if it has not been installed, with free collection on the mainland, and shipment tracking by email.

## Frequently asked questions

### How is the Deta DB740 battery installed in the vehicle?

In most cars 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 right match the polarity shown on the product sheet; 6) connect the positive (+) first, then the negative (−). On cars 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 DB740 model?

Expected lifespan of the Deta DB740 is 4 to 6 years in regular car 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 Deta DB740 battery?

Dimensions (length × width × height) are 278×175×190 mm — also written as 278x175x190 mm and correspond to the European L3 case size — following the European DIN standard. Always measure the space in your car before buying: even one extra millimetre can prevent the hold-down clamp from closing. The height shown includes the terminals.

### What polarity does the Deta DB740 battery have?

Polarity: positive on the right. 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.

### Does this battery fit my car?

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 DB740 fits 181 verified vehicle versions in our database.

### Which batteries are equivalent to the Deta DB740?

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 cars. See the "Equivalents" section to view recommended options at the same performance level.
