CTEK M15 Automatic Marine Boat Battery Charger Maintainer 12V Lead Acid Lithium

$508.70 AUD

The CTEK M15 charges a wide range of marine batteries quickly and effectively. The rugged, impact-resistant casing means it can handle the toughest environments, so these chargers can be used on many different marine products and power a range of vessels, from fishing boats or weekend cruisers, to the outdoor adventurer using their boat for water skiing or wakeboarding.

The M15 has a unique maintenance program that means it can be connected to the battery indefinitely, if the boat is moored for longer periods of time, or if the boat is taken out of the water for the Winter.

It has a range of functions, including a Recond mode for reconditioning deeply discharged Wet and Ca/Ca batteries, and a temperature sensor which optimises the charge if the temperature deviates from +25ºC. It also has a dedicated mode for lithium ­batteries (LiFePO4, Li-Fe, Li-iron, LFP). The CTEK M15 comes with a long 4m ­cable with M10 eyelets for easy installation on your boat.

Ensure your boat is ready to go whenever you are with the CTEK M15.
