Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 14.47 kg and F4 terminals. ### Dimensions, polarity and mounting It has external dimensions of 198 × 166 × 171 mm and weighs 14.47 kg. It uses F4 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. ### Kronobat: the maker behind the ES45-12 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. All the Kronobat batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty. ### The Kronobat ES45-12: AGM Deep Cycle range and AGM technology Within the Kronobat catalogue, the **AGM Deep Cycle** series groups the references designed for this use. The ES45-12 is the 45 Ah model of that family, with the same performance as its siblings in other sizes. In an AGM battery the electrolyte is absorbed in glass-fibre separators: there is no free liquid, it cannot spill and it can be mounted at an angle. That construction lowers internal resistance, speeds up recharging and multiplies cycle life compared with a conventional battery. ### Usage and maintenance tips Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators. Use the original charger or one compatible with the battery technology (AGM/GEL) and always replace both batteries in the set together. ### Official warranty The Kronobat ES45-12 comes with the **manufacturer's official warranty** against manufacturing defects. If it fails through a defect within the warranty period, we replace it at no cost to you. ### When you get it and how to return it Orders placed **before 6:00 pm** with the battery in stock ship the same day.

We email you the tracking number as soon as the parcel ships. ## Frequently asked questions ### Is the Kronobat ES45-12 an AGM battery and what are the benefits of AGM? Yes: the ES45-12 from Kronobat uses AGM (Absorbent Glass Mat) technology, a sealed lead-acid battery whose electrolyte soaks a glass-fibre mat. It tolerates heat better and handles more cycles than a conventional battery. ### What are the measurements of the ES45-12 model? The Kronobat ES45-12 takes up 198×166×171 mm (length, width and height, terminals included). Before buying, measure the space in your device: one extra millimetre can stop the hold-down clamp from closing. ## Equivalent batteries - [MK POWERED M45-12 SLD M](https://baterias.com/gb/battery-mk-m45-12-sld-m-12v-45ah) - [MK POWERED M50-12 SLD M](https://baterias.com/gb/battery-mk-m50-12-sld-m-agm-12v-50ah) - [Q-battery BATTERY-12LCP-50](https://baterias.com/gb/battery-q-battery-12lcp-50-12v-50ah) ## 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 · 2026-11-11*
