Kronobat LI12V100AhBT 12V is a LiFePO4 lithium service battery for boats, designed to power onboard loads (fridge, fishfinder, GPS, lights, inverter) through deep daily discharges. 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 bankdaily discharges to 80 % with no capacity loss
- 60 % less weight on boardthe same energy as lead-acid in far less space
- Built-in BMS, maintenance freeprotects against overcharge, over-discharge and short circuit

What the Kronobat LI12V100AhBT is for
With 100 Ah, the Kronobat LI12V100AhBT 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 11 kg.
Technology inside the Kronobat LI12V100AhBT
Within the Kronobat catalogue, the LI12V100AhBT is the 100 Ah model designed for this application.
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.

Frequently asked questions
How is the Kronobat LI12V100AhBT battery installed in the vehicle?
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 our blog. 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 LI12V100AhBT model?
Expected lifespan of the Kronobat LI12V100AhBT 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 LI12V100AhBT 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 LI12V100AhBT 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 LI12V100AhBT typically fits a wide range of European vehicles thanks to its standard DIN case format.
Which batteries are equivalent to the Kronobat LI12V100AhBT?
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.
