- What are alkaline AA and AAA batteries?
If you don't use a lot of batteries and the devices that you do have are not gobbling up your alkalines - you can still use them, you can't beat em for convenience and initial cost. However, if you use lots of them like many people do you are wasting money and you need to consider using rechargeable batteries.
- What are AA AAA used for?
AAA batteries are commonly used in small electronic devices, such as TV remote controls, MP3-players and digital cameras. Devices that require the same voltage, but have a higher current draw, are often designed to use larger batteries such as the AA battery type. AA batteries have about three times the capacity of AAA batteries. However, with the increasing efficiency and miniaturization of modern electronics, many devices which previously were designed for AA batteries-remote controls, computer mice, and keyboards-are being replaced by models that accept AAA cells.
- What's the difference between a rapid charger and a fast charger?
Both terms are essentially meaningless. There is no standard in the industry, so manufacturers can use the terms in different ways. One of the problems with terms like these is that the amount of time it takes to charge a battery is dependent on the capacity of the battery being charged. A charger that can charge a standard capacity AAA NiCD battery (180 mAh) in just one hour might take 8 hours to charge a high capacity NiMH (1500 mAh) battery. It's best to ignore such terms and make a rough calculation of how fast a charger can charge batteries.
