The charging time for AAA batteries can range from 1 to 4 hours, depending on the capacity of the batteries and the charging rate of the charger being used. It is important to follow the manufacturer's recommendations for charging times to avoid overcharging the batteries.
Yes, your charger should be able to charge AAA 1800mAh batteries. It is common for battery chargers to be able to charge multiple capacities of batteries as long as they are compatible with the chemistry (e.g. NiMH, NiCd) and size (AA, AAA). Just make sure to follow the manufacturer's instructions for optimal performance and safety.
With the same load current the AA will last longer that the AAA. This is due to the physical size of the cells. A C cell will last longer that a AA and a D cell will last longer that a C cell. In dry cells as the cells get larger the amp/hours increase.
Assuming each AAA battery has a capacity of around 1200mAh, three in series would provide a total voltage of 4.5V and a capacity of 1200mAh. A 13-watt LED running at 4.5V would draw approximately 2.89A. This setup could power the LED for around 24 minutes before the batteries would need to be replaced or recharged due to the limited energy capacity.
Normal clocks use little power, for example I have one that lasts 1 year with a single AAA battery.

Many different battery brands include AAA batteries some examples of AAA battery brands include two of the biggest battery brands, Energizer and Duracell.
Duracell Rechargeable StayCharged AAA Batteries, 4-Count by Duracell I bought some Duracell rechargeable AAA NiMH Batteries and I would not buy them again because the charge does not It's four triple-A batteries as advertised.
Duracell!!!

All AA batteries are 1.5v "though it should say so on the label"
Battery brand isn't that important. The time to charge is mainly dependent on the capacity of the battery and the capacity of the charger. Any reasonable modern charger should sense when the battery is full and cut power when it's done. It can take some hours for a full charge.
2 days fool!
depends wat on more then a normal battery anyway
Duracell rechargeable batteries costs on average $16.00-$18.00 for a 4pk AA, 4PK AAA, 2PK C, or a 2PK D. If you purchase Duracell rechargeable batteries in a larger quantity, you are sure to find them for as little as $24.00-$28.00 for an 8pk AA, 8PK AAA, 4PK C or a 4PK D.
Guinness world record confirmed that Panasonic's EVOLTA AA batteries are the longest lasting.
