### Will it fit your current battery tray?

The Deta DB442 is made in the 207 × 175 × 175 mm format and weighs 10.60 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. 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.

### What the Deta DB442 is for

The Deta DB442 covers the needs of passenger cars with conventional starting, without a Start-Stop system: reliable starting, stable voltage for the electronics and a service life of several years in daily use. Check that it matches your current battery in size and terminal position. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 10.60 kg and B13 hold-down.

### The Deta DB442: Power range and conventional lead-acid technology

The **Power** is the Deta range the DB442 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.

### What Deta does differently

Deta is the German brand of the Exide group: batteries built with original-equipment technology and a very complete range for cars, Start-Stop, trucks, motorcycles and leisure. All the Deta batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty.

### Manufacturer's warranty

The Deta DB442 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.

### How to make it last longer

Keep the terminals clean and tight, and check that the resting voltage does not drop below 12.4 V: below that it is time to recharge. Avoid leaving lights or accessories on with the engine off: most batteries fail not through defects but through repeated deep discharges.

### When you get it and how to return it

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.

## Frequently asked questions

### How is the Deta DB442 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.

### How long does the Deta DB442 battery last?

Expected lifespan of the Deta DB442 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 size is this battery?

Dimensions (length × width × height) are 207×175×175 mm — also written as 207x175x175 mm and correspond to the European LB1 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 DB442 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.

### Is the DB442 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 DB442 fits 306 verified vehicle versions in our database.

### Which batteries are equivalent to the Deta DB442?

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.
