It measures 530 × 230 × 220 mm, the format sought by anyone replacing a 200 Ah battery in boats. - Tolerates the daily cycling of a boat in season. - Powers onboard services: lights, sounder, GPS, fridge. - Reinforced case against vibration and swell. - LiFePO4 lithium: minimal weight and almost zero self-discharge. ### What the Kronobat LI12V200AhBT is for With 200 Ah, the Kronobat LI12V200AhBT covers motor and sailing boats, both for engine starting and onboard services. At the end of the season, charge it fully before winter storage. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 20 kg. ### Technology inside the Kronobat LI12V200AhBT The LI12V200AhBT is one of the Kronobat references for this type of use; it shares the same manufacturing and quality-control criteria as the rest of the brand's catalogue. Lithium iron phosphate (LiFePO4) offers far higher energy density than lead: the battery weighs a fraction, hardly self-discharges and withstands thousands of cycles. A built-in BMS monitors voltage, temperature and cell balance. ### Dimensions, polarity and mounting It has external dimensions of 530 × 230 × 220 mm and weighs 20 kg. 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 LI12V200AhBT 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. ### Usage and maintenance tips Store the battery at 50-70% charge if it will be unused for months. At the end of the season, charge the battery fully and, if possible, keep it on a charger over the winter lay-up. ### Manufacturer's warranty The Kronobat LI12V200AhBT comes with the **manufacturer's official warranty** against manufacturing defects. Deep discharge from winter lay-up without charging is not covered. ### When you get it and how to return it Orders placed **before [[ks:cutoff]]** with the battery in stock ship the same day.

In most boats 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 (−) 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 boats with Start-Stop or BMS, register the battery via OBD so the alternator applies the correct charging profile. ### How long does the Kronobat LI12V200AhBT battery last? Expected lifespan of the Kronobat LI12V200AhBT is 10 to 15 years, equivalent to 3,000-5,000 cycles at 80% DoD. 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 LI12V200AhBT battery? Dimensions (length × width × height) are 530×230×220 mm — also written as 530x230x220 mm — following the European DIN standard. Always measure the space in your boat before buying: even one extra millimetre can prevent the hold-down clamp from closing. The height shown includes the terminals. ### Will the Kronobat LI12V200AhBT battery fit my boat? 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 LI12V200AhBT typically fits a wide range of European vehicles thanks to its standard DIN case format. ### What are the equivalents of the LI12V200AhBT 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 — an EFB cannot be replaced with a conventional battery in Start-Stop boats. See the "Equivalents" section to view recommended options at the same performance level. ## Technical team (editorial authorship) The FAQs, guides and comparisons on this site are reviewed by the baterias.com technical team — automotive battery specialists since 2015. → https://baterias.com/gb/technical-team --- *baterias.com — Automotive batteries · 2026-10-10*
