7.The charger has a 3-year worldwide warranty, however, damages from misusing the charger will not be included in the coverage of

warranty.

At the beginning stage of operation, the charger provides the largest current with 14.4Vdc of output voltage (for 12V batteries) to

charge batteries. The LED indicator will lighten in red and the built-in fan will spin to dissipate the heat (360W only). After a period of

time (probably a couple of hours, based on the capacity of batteries), the charging current will decrease gradually. After reaching 10%

of its maximum value, the charger will go into "floating-charge" stage. The fan will stop spinning, charging voltage will decrease to

13.6Vdc, and the LED indicator will turn to green. The relationship between charging current and charging voltage for each operation
