Measuring 238 Γ— 129 Γ— 227 mm and the positive terminal on the left, it is the direct replacement for cars fitted from the factory with a 45 Ah battery of this format. - Low self-discharge: copes with long stops without losing charge. - Designed to last several years under normal daily use. - Good balance of capacity, cranking power and price. - Stable voltage for the vehicle electronics (ECU, sensors, climate control). ### Dimensions, polarity and mounting In terms of format, the Kronobat PB-45.1T measures 238 Γ— 129 Γ— 227 mm (length Γ— width Γ— 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 1.0 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 the Kronobat PB-45.1T is for Designed for passenger cars with conventional starting, without a Start-Stop system, the Kronobat PB-45.1T 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 1.0 terminals. ### The Kronobat PB-45.1T: Premium range and conventional lead-acid technology The **Premium** is the Kronobat range the PB-45.1T 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 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. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty. ### Official warranty The Kronobat PB-45.1T 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 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. On batteries with filler caps, check the electrolyte level and top up only with distilled water. ### When you get it and how to return it Same-day dispatch from our warehouse for in-stock orders placed **before [[ks:cutoff]]**: 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 **[[ks:return_days]] days** if the battery has not been used (free collection on the Iberian mainland). You will receive tracking by email. ## Frequently asked questions ### How do I fit the PB-45.1T model in my car? 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 this page. 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 (βˆ’) 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 β€” match the polarity shown on the product sheet; 6) connect the positive (+) first, then the negative (βˆ’). On cars with Start-Stop or BMS, register the battery via OBD so the alternator applies the correct charging profile. ### How long does the Kronobat PB-45.1T battery last? Expected lifespan of the Kronobat PB-45.1T 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 Γ— width Γ— height) are 238Γ—129Γ—227 mm β€” also written as 238x129x227 mm β€” 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-45.1T 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 β€” we reply during business hours (Mon–Fri 10:00–13:30 and 16:40–18:00 (Spanish time, CET)). The PB-45.1T typically fits a wide range of European vehicles thanks to its standard DIN case format. ### What are the equivalents of the PB-45.1T model? 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 β€” 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. ## Equivalent batteries - [VARTA B34](https://baterias.com/gb/battery-varta-b34-12v-45ah-330a) - [TUDOR TB455](https://baterias.com/gb/battery-tudor-tb455-45ah-330a) - [EXIDE EB455](https://baterias.com/gb/battery-exide-eb455-12v-45ah-300a) - [EXIDE EK457](https://baterias.com/gb/battery-exide-ek457-12v-45ah) ## Technical team (editorial authorship) The FAQs, guides and comparisons on this site are reviewed by the baterias.com technical team β€” over 25 years of experience validating automotive batteries. β†’ https://baterias.com/gb/technical-team --- *baterias.com β€” Automotive batteries Β· 2026-10-06*
