It is not a starting battery: it replaces the lead-acid service bank at around 60 % less weight. ## Why this lithium marine battery? - **Deep-cycle service bank** daily discharges to 80 % with no capacity loss - **60 % less weight on board** the same energy as lead-acid in far less space - **Built-in BMS, maintenance free** protects against overcharge, over-discharge and short circuit 🔌 Voltage 12 V 📏 Dimensions 340×175×220 mm ⚙️ Technology LiFePo4 ⚖️ Weight 11,5 kg 🏷️ Model LIFEPO4 ## Description ## Marine battery Kronobat LI12V100Ah 100Ah 12V 12*V* Voltage 100*Ah* Capacity 11*kg* Weight With **100 Ah** at **12 V**, the **Kronobat LI12V100Ah** is built for motor and sailing boats, both for engine starting and onboard services. Its 340 × 175 × 220 mm make it the exact replacement for the 100 Ah battery fitted as standard to many boats. - Resistant to humidity and salt air. - Sealed: no spills or gases in the locker. - Ready for starting outboard and inboard engines. - Built-in BMS protecting the battery and the vehicle. ### What the Kronobat LI12V100Ah is for The Kronobat LI12V100Ah is designed for motor and sailing boats, both for engine starting and onboard services. If it is your starter battery, run the services from a separate battery; if it is a service battery, avoid routinely discharging it beyond 50%. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 11 kg and M08 terminals. ### Dimensions, polarity and mounting In terms of format, the Kronobat LI12V100Ah measures 340 × 175 × 220 mm (length × width × height) and weighs 11 kg. It uses M08 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. ### Technology inside the Kronobat LI12V100Ah The LI12V100Ah 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. A LiFePO4 battery starts with the same nominal voltage as a lead-acid one but with far less weight and a service life several times longer. It requires a lithium-compatible charger. ### Why choose Kronobat batteries 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. ### Manufacturer's warranty The Kronobat LI12V100Ah comes with the **manufacturer's official warranty** against manufacturing defects. Deep discharge from winter lay-up without charging is not covered. ### Usage and maintenance tips At the end of the season, charge the battery fully and, if possible, keep it on a charger over the winter lay-up. Protect the terminals with dielectric grease and check the fixing: vibration and swell loosen connections. ### Delivery times and returns 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 LI12V100Ah model in my boat? 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. ### What is the service life of the LI12V100Ah model? Expected lifespan of the Kronobat LI12V100Ah 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 size is this battery? Dimensions (length × width × height) are 340×175×220 mm — also written as 340x175x220 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. ### Is the LI12V100Ah valid for my vehicle? 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 LI12V100Ah typically fits a wide range of European vehicles thanks to its standard DIN case format. ### Which interchangeable batteries are there for this one? 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 · 2026-10-12*
