It replaces the original battery without adaptation in cars with a 238 × 129 × 227 mm format: same 45 Ah capacity and the positive terminal on the left. - Direct replacement for the original battery in size and terminals. - Original-equipment build quality without the dealership price. - Conventional lead-acid: the most proven and economical technology. - Reliable cold starts, even after weeks without driving. ### What the Kronobat PB-45.1F is for Designed for passenger cars with conventional starting, without a Start-Stop system, the Kronobat PB-45.1F 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-45.1F: Premium range and conventional lead-acid technology The PB-45.1F is part of the Kronobat **Premium** range. Choosing the right reference within the series comes down to capacity, dimensions and terminals: technology and quality are common to the whole family. Conventional lead-acid is the benchmark against which other technologies are compared: good cranking current, great tolerance to alternator charging and the best price per amp-hour. ### Dimensions, polarity and mounting In terms of format, the Kronobat PB-45.1F measures 238 × 129 × 227 mm (length × width × height) and weighs 11.70 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 3.0 terminals, 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 Kronobat does differently With Kronobat we offer an own-brand alternative without compromising on quality: European manufacturing, original-equipment controls and the direct backing of baterias.com for warranty and advice. We guarantee that every Kronobat arrives new, charged and with the manufacturer's full warranty. ### How to make it last longer Avoid leaving lights or accessories on with the engine off: most batteries fail not through defects but through repeated deep discharges. 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. ### Official warranty The Kronobat PB-45.1F 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. ### Delivery times and returns 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-45.1F battery installed in the vehicle? Before you start, check the car handbook: the manufacturer's procedure always comes first. Our full step-by-step guide is on the blog. With a 10 mm spanner, swapping in the Kronobat PB-45.1F takes 15 to 30 minutes on most cars; if the battery sits in the boot or under a seat, allow 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 left (polarity). ### How many years does this battery last? Estimated lifespan of the Kronobat PB-45.1F: 4 to 6 years in regular car use without Start-Stop. Treat it as an approximate guide, as every case is different. Actual lifespan varies with climate (cold starts, heat evaporating the electrolyte), with usage and short journeys, with the condition of the alternator and charging system, with power draw while parked and with maintenance; the type of car and Start-Stop also count. ### What size is this battery? The Kronobat PB-45.1F takes up 238×129×227 mm (length, width and height, terminals included). Before buying, measure the space in your car: one extra millimetre can stop the hold-down clamp from closing. ### On which side is the positive of the PB-45.1F model? The PB-45.1F has the positive on the left: that is its polarity. Face the battery with its terminals nearest you and see which side the positive post (+, red ring) is on. Compare it with the battery you are replacing: if it does not match, cables must be lengthened or the system reconfigured, with a risk of short circuit. ### Will the Kronobat PB-45.1F battery fit my car? The PB-45.1F typically fits a wide range of European vehicles thanks to its standard DIN case format. The quickest way is to enter your number plate in the finder: DGT/DVLA/KBA detect model and engine. You can also look at the "Compatible vehicles" tab, verified by our technical team, or send us make, model, engine and year on WhatsApp; we answer 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. ### Which interchangeable batteries are there for this one? The "Equivalents" section of this page gathers the recommended options with equivalent performance; remember that in Start-Stop cars an EFB should not be replaced with a conventional battery. A direct equivalent needs what this PB-45.1F offers: 238×129×227 mm, positive on the left, the same Ah and CCA and conventional technology. ### Kronobat PB-45.1F or Varta B33: which one to choose? The Varta alternative that fits where the PB-45.1F goes, with the same polarity. Compared with the PB-45.1F it has the same Ah and cranking power. It costs €49.80 more. A straight swap with nothing to adapt; the difference is the price and the brand you prefer. ### Kronobat PB-45.1F or Varta A11: which one to choose? A technology step up: sealed AGM, with stronger cranking and a noticeably longer life than the PB-45.1F when the car draws a lot of power. Compared with the PB-45.1F 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-45.1F is plenty. ## Equivalent batteries - [VARTA B33](https://baterias.com/gb/battery-varta-b33-12v-45ah-330a) - [TUDOR TB457](https://baterias.com/gb/battery-tudor-tb457-45ah-330a) - [EXIDE EB457](https://baterias.com/gb/battery-exide-eb457-12v-45ah-300a) - [VARTA A11](https://baterias.com/gb/battery-varta-dynamic-agm-a11-45ah) - [EXIDE EK457](https://baterias.com/gb/battery-exide-ek457-12v-45ah) - [TUDOR TK457](https://baterias.com/gb/battery-tudor-tk457-12v-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*
