This inexpensive universal battery charger has an automatic timer that charges AA, AAA, C, and D batteries for various times ~4-8 hours, depending on the type and capacity of the battery and then switches to trickle charge mode to assure a full charge. For 9 volt batteries it takes longer, ~10-15 hours, and there is no trickle charge.
