The MariCell 12.8V 40Ah CCA500 is the ultimate starting solution for small to midsize motors, engineered to provide the high-burst "cold cranking amps" (CCA) needed to fire up outboards and engines instantly. Unlike standard deep-cycle batteries, this specialized cranking battery delivers a 500CCA punch, ensuring your motor turns over even in chilly mornings. With integrated Bluetooth monitoring and a high-discharge BMS, it offers the perfect blend of starting power and intelligent safety. Compact and rugged, it is designed to replace heavy lead-acid starting batteries, shedding significant weight from your boat’s transom while delivering 10 years of reliable service.
Voltage: 12.8V
Capacity: 40Ah (512Wh)
Cranking Amps: 500CCA
Weight: 11 lbs
IP Rating: IP65 Waterproof
Dimensions: 7.75 x 5.12 × 7.80 inches

Take the guesswork out of your engine's health. With built-in Bluetooth connectivity, you can use our mobile app to check your battery’s real-time voltage and State of Charge (SOC) from the captain's chair. Ensure you have plenty of juice for that next ignition cycle without ever opening the battery compartment.
Equipped with a specialized Battery Management System designed for high-current bursts, this battery handles the intense demands of engine starting. The BMS provides critical protection against over-cranking, short circuits, and extreme temperatures, ensuring the LiFePO4 cells remain stable and safe during every ignition.
Built for the vibrations of a speeding hull and the spray of the open sea, this battery features an IP65-rated housing. It includes advanced cold-temperature protection, ensuring that even when the frost hits the docks, your 500CCA output remains ready. Using Grade A LiFePO4 cells, it offers a lifespan of 4,000–15,000 cycles—lasting up to 10 times longer than traditional lead-acid starting batteries.
At just 11.5 lbs, the MariCell Lithium 40Ah Cranking battery is a fraction of the weight of traditional Group 24 starting batteries. This reduction in "stern heavy" weight improves your boat's holeshot, top-end speed, and fuel efficiency, all while fitting into the tightest battery trays and compartments.
While designed as a dedicated starting battery, it can be connected in parallel (up to 4P) to increase cranking headroom or capacity for larger vessels. It is the perfect companion to our deep-cycle "Mini" series, creating a comprehensive, lightweight power system for your entire boat.
We stand by our power with a standard five-year warranty and 24-hour professional support. Register your battery after purchase to extend your coverage to a full 7 years, ensuring your time on the water is backed by the best service in the industry.
