## Description

## 12V 74Ah 680A battery (L3): Kronobat PB-74.0 and its equivalents

The **Kronobat PB-74.0** is a conventional car battery with **74 Ah and 680 A** cold cranking in the L3 format (278 × 175 × 190 mm, positive on the right). It is baterias.com's value option for this size: the same maintenance-free lead-acid technology as the premium brands, with a 2-year warranty. If you prefer a premium brand or the Kronobat is out of stock, these batteries have the **same dimensions and polarity** and fit the same cars:

| Battery | Range | Height | Current price |
|---|---|---|---|
| Varta E11 | Blue Dynamic | 190 mm | See price and stock |
| Tudor TB740 | Technica | 190 mm | See price and stock |
| Exide EB740 | Excell | 190 mm | See price and stock |
| Varta E38 | Silver Dynamic · 750 A | 175 mm | See price and stock |

### When to choose the Kronobat PB-74.0

Cars without Start-Stop, daily use and a tight budget. It matches a premium brand of the same size in cranking and capacity; the difference is expected service life (4-5 years versus 5-7) and price.

### When to choose Varta, Tudor or Exide

Cars with heavy electrical loads (climate control, heated seats, audio), short city trips, or if you want the longest life. The Varta E11 and the Tudor TB740 are the two best sellers of this size at baterias.com.

### Check before you buy

- Dimensions: length 278 mm and width 175 mm are fixed; height is 175 or 190 mm depending on the car (measure your current battery).
- Polarity: positive on the right with the terminals facing you. If yours is on the left, you need the "1" version of the format.
- If your car has Start-Stop, none of these fit: it needs an [EFB or AGM battery](https://baterias.com/gb/car-batteries-equipped-with-start-stop-system).
- Enter your number plate in the finder above and we confirm the exact fit.

## Frequently asked questions

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

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 — 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 many years does this battery last?

Expected lifespan of the Kronobat PB-74.0 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 Kronobat PB-74.0 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.

### Will the Kronobat PB-74.0 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 PB-74.0 typically fits a wide range of European vehicles thanks to its standard DIN case format.

### Which batteries are equivalent to the Kronobat PB-74.0?

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.
