Measuring 238 × 129 × 227 mm and the positive terminal on the right, it is the direct replacement for cars fitted from the factory with a 45 Ah battery of this format. - Good balance of capacity, cranking power and price. - Stable voltage for the vehicle electronics (ECU, sensors, climate control). - Low self-discharge: copes with long stops without losing charge. - Designed to last several years under normal daily use. ### What the Kronobat PB-45.0F is for Designed for passenger cars with conventional starting, without a Start-Stop system, the Kronobat PB-45.0F is the direct replacement when your vehicle uses a 45 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 11.70 kg and 3.0 terminals. ### The Kronobat PB-45.0F: Premium range and conventional lead-acid technology The **Premium** is the Kronobat range the PB-45.0F 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. ### Dimensions, polarity and mounting In terms of format, the Kronobat PB-45.0F measures 238 × 129 × 227 mm (length × width × height) and weighs 11.70 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 3.0 terminals, the system that anchors and connects it in the vehicle. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery. ### Kronobat: the maker behind the PB-45.0F Kronobat is the exclusive brand of baterias.com: batteries made to the same production standards as the leading brands, with a value for money that is hard to match and an official warranty. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty. ### How to make it last longer On batteries with filler caps, check the electrolyte level and top up only with distilled water. 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. ### Manufacturer's warranty The Kronobat PB-45.0F 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. ### When you get it and how to return it Order **before 6:00 pm** 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 **14 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 Kronobat PB-45.0F battery installed in the vehicle? Our blog guide covers it in detail; if the owner's handbook describes a different procedure, follow the manufacturer. Allow 15-30 minutes and a 10 mm spanner. If the car keeps its battery in the boot or under a seat, it can take up to twice as long. What matters most is the terminal order: removing, negative (−) before positive (+); refitting, positive (+) before negative (−). In between, with the engine off and the key out, release the clamp and fit the new battery the same way round as the original, positive on the right (polarity). ### What is the service life of the PB-45.0F model? As a guide, you can expect the Kronobat PB-45.0F to last 4 to 6 years in regular car use without Start-Stop, although the real figure may be higher or lower. Many factors play a part: how it is used (lots of short trips, for example), temperature (cold makes every start harder and intense heat evaporates the electrolyte), the condition of the alternator and charging system, power drawn with the engine off and maintenance, as well as the type of car and whether it has Start-Stop. ### What are the dimensions of the Kronobat PB-45.0F battery? Before buying, measure the space in your car: one extra millimetre can stop the hold-down clamp from closing. The Kronobat PB-45.0F takes up 238×129×227 mm (length, width and height, terminals included). ### On which side is the positive of the PB-45.0F model? On the Kronobat PB-45.0F, the polarity is positive on the right. If your current battery has its positive on the other side, this one is not suitable without longer cables or a reconfigured system (short-circuit risk). To check, stand the battery in front of you with the terminals nearest you: the positive (+) is the one with the red ring. ### Is the PB-45.0F valid for my vehicle? For your own vehicle: type your number plate into the finder (DGT/DVLA/KBA identify model and engine), check the "Compatible vehicles" tab below, listing vehicles verified by our technical team, or message us on WhatsApp with make, model, engine and year; we reply during business hours (Mon–Fri 10:00–13:30 and 16:30–18:00 (Spanish time, CET)). The car manufacturer's specifications always take priority over our tables. ### What are the equivalents of the PB-45.0F model? A direct equivalent needs what this PB-45.0F offers: 238×129×227 mm, positive on the right, the same Ah and CCA and conventional technology. Not just any technology will do: an EFB cannot be replaced with a conventional battery in Start-Stop cars. The "Equivalents" section further down lists the recommended alternatives. ### Kronobat PB-45.0F or Varta B31: which one to choose? It is the verified Varta equivalent for the PB-45.0F tray. Compared with the PB-45.0F it has the same Ah and cranking power. It costs €47.60 more. Decide by price, brand preference and availability: both fit and crank the same. ### Kronobat PB-45.0F or Varta A11: which one to choose? A technology step up: sealed AGM, with stronger cranking and a noticeably longer life than the PB-45.0F when the car draws a lot of power. Compared with the PB-45.0F it has 40 A of cold cranking more. It costs €138.60 more. Choose it if your car required it from the factory or if you want the longest-lasting battery for this size; for normal use without Start-Stop, the PB-45.0F is plenty. ## Equivalent batteries - [VARTA B31](https://baterias.com/gb/battery-varta-b31-12v-45ah-330a) - [TUDOR TB456](https://baterias.com/gb/battery-tudor-tb456-45ah-330a) - [TUDOR TA456](https://baterias.com/gb/battery-tudor-ta456-12v-45ah-390a) - [EXIDE EA456](https://baterias.com/gb/battery-exide-ea456-12v-45ah-390a) - [EXIDE EB456](https://baterias.com/gb/battery-exide-eb456-12v-45ah-300a) - [EXIDE EK454](https://baterias.com/gb/battery-exide-ek454-12v-45ah) ## Technical team (editorial authorship) The FAQs, guides and comparisons on this site are reviewed by the baterias.com technical team — automotive battery specialists since 2012. → https://baterias.com/gb/technical-team --- *baterias.com — Automotive batteries · 2026-11-08*
