[. . . ] This charger is designed to charge NI-Cd or NI-MH batteries in the following sizes/quantities : - 2 or 4 batteries size AAA / R03, - 2 or 4 batteries size AA / R06 - 1 battery size 9V block/R22/PP3 2. Insert the batteries size AAA/R03, AA/R06 or 9V/PP3 into the charger compartments, taking care to observe polarity (+/-) as indicated inside the charger. [. . . ] The indicator light extinguishes indicating that charging is complete and that the charger has switched to a maintenance charge.

Do not expose the charger to high temperatures or allow moisture or humidity of any kind to come into contact with the charger.
