VICTRON ENERGY BLUE SMART 24 VOLT BATTERY CHARGER - IP22 - 180-265VAC THREE OUTPUTS 16 AMP CHARGING UK PLUG WITH BLUETOOTH INSIDE APPLICATIONS: AUTOMTIVE, FLOODED, AGM, GEL, LIFEPO4 (LITHIUM) BATTERIES Big Features in a Small Size at a Small Price Blue Power IP22 Battery Charger: The highest efficiency ever! With up to 94% efficiency, these chargers generate up to four times less heat when compared to the industry standard. And once the battery is fully charged, power consumption reduces to 0,5 Watt, some five to ten times better than the industry standard. NIGHT and LOW setting When in NIGHT or LOW mode, the output current is reduced to max. 25% of the nominal output and the charger will be totally noiseless. The NIGHT mode automatically ends after 8 hours. The LOW mode can be ended manually. Storage Mode: Less maintenance and aging when the battery is not in use The storage mode kicks in whenever the battery has not been subjected to discharge during 24 hours. In the storage mode float voltage is reduced to minimize gassing and corrosion of the positive plates. Once a week the voltage is raised back to the absorption level to ‘equalize' the battery. This feature prevents stratification of the electrolyte and sulfation, a major cause of early battery failure.
