Compare and buy online. ## LiFePO4: lighter and more usable capacity Lithium iron phosphate (LiFePO4) batteries have a nominal voltage of 12.8 V and are designed as direct replacements for 12 V lead-acid leisure batteries. Compared with lead, they weigh much less, keep a steady voltage during discharge and allow a much larger share of their capacity to be used without damage. They are a popular choice for boats, motorhomes, campervans and off-grid solar systems. We list more than 20 LiFePO4 batteries from Exide, Fulbat and Varta (6 each) and Kronobat (4), from 50 to 200 Ah. Exide's range covers many capacities: - **EV640S** (50 Ah) and **EV1250S** (96 Ah). - **EV1300S** (100 Ah) and **EV1600** (125 Ah, 12.8 V). - **EV1920S** (150 Ah) and **EV2500S** (200 Ah). Kronobat offers 100 Ah models such as the LI12V100Ah and LI12V100AhBT. ## What you need to switch to lithium Use a charger with a lithium profile: see [lithium battery chargers](https://bateriasonline.es/en/lithium-battery-chargers). Check that your alternator charging, solar controller and battery monitor support LiFePO4.

Check each product page: LiFePO4 batteries like these are mainly intended for service use, and whether one can start an engine depends on its maximum discharge current. ### Can I replace an AGM leisure battery with LiFePO4? Yes, in most cases, provided the charging equipment has a lithium setting. ## Choose by brand The same 12 V LiFePO4 lithium batteries, filtered by manufacturer. Each brand has its own page with all its references and a buying guide. - [Exide batteries](https://bateriasonline.es/en/exide-batteries) (6) - [Varta batteries](https://bateriasonline.es/en/varta-batteries) (6) - [Fulbat batteries](https://bateriasonline.es/en/fulbat-batteries) (6) - [Kronobat batteries](https://bateriasonline.es/en/kronobat-batteries) (4) ## Products in this category | Product | Brand | Price | |---|---|---| | [Exide EV1600 · Boat battery 12.8V 125Ah](https://bateriasonline.es/en/exide-ev1600) | Exide | 1.154,64 € | | [Exide EV2500S · Boat battery 12V 200Ah](https://bateriasonline.es/en/exide-ev2500s) | Exide | 2.967,39 € | | [Exide EV1300S · Boat battery 12V 100Ah](https://bateriasonline.es/en/exide-ev1300s) | Exide | 1.539,29 € | | [Exide EV1250S · Boat battery 12V 96Ah](https://bateriasonline.es/en/exide-ev1250s) | Exide | 1.438,93 € | | [Exide EV640S · Boat battery 12V 50Ah](https://bateriasonline.es/en/exide-ev640s) | Exide | 911,99 € | | [Exide EV1920S · Boat battery 12V 150Ah](https://bateriasonline.es/en/exide-ev1920s) | Exide | 780,28 € | | [Fulbat FLP12-100B · Floor scrubber battery 12.8V 100Ah](https://bateriasonline.es/en/fulbat-flp12-100b) | Fulbat | 373,25 € | | [Fulbat FLP12-84/100L · Floor scrubber battery 12.8V 100Ah](https://bateriasonline.es/en/fulbat-flp12-84-100l) | Fulbat | 306,84 € | | [Kronobat LI12V100AhBT · Boat battery 12V 100Ah](https://bateriasonline.es/en/kronobat-li12v100ahbt) | Kronobat | 650,67 € | | [Kronobat LI12V100Ah · Boat battery 12V 100Ah](https://bateriasonline.es/en/kronobat-li12v100ah) | Kronobat | 541,45 € | | [Kronobat LI12V200AhBT · Boat battery 12V 200Ah](https://bateriasonline.es/en/kronobat-li12v200ahbt) | Kronobat | 1.147,87 € | | [Kronobat LI12V200Ah · Boat battery 12V 200Ah](https://bateriasonline.es/en/kronobat-li12v200ah) | Kronobat | 1.038,60 € | --- *bateriasonline.es — Batteries and accessories · 2026-11-11*
