I want to put 4 AA NiCad or NimH batteries in a holder (Radio Shack 270-383) and connect two set of positive and negative leads. One to a DC Power Jack (Radio Shack 274-1565) for when the battery pack needs to be recharged and the other to a DC Power Plug (Radio Shack 274-1567) for when I want to use their power. Will this work?
Sounds like a plan to me. 6 volts, I presume?
An AA battery (pronounced either ay-ay or double A) is a dry cell-type battery commonly used in portable electronic devices. Electrical output of alkaline batteries in this size is 1.5 volts, 1800 to 2600 mA·h, while rechargeable batteries commonly output variably 1.25 V. The output of an AA battery is the same as that of an AAA battery, but AA batteries provide power for a longer period (hence their larger size). An AA cell measures 50 mm long, 14.2 mm in diameter, and weighs approximately 23 g (1.97 x 0.56 inches and 0.81 ounces). The capacity of rechargeable AA batteries varies with the technology used. Nickel-cadmium (NiCad) AAs with a capacity of 650 to 800 mA·h are commonly available, while 800 to 1000 mA·h are rarer and more expensive. Nickel metal hydride (NiMH) AAs are available in various capacities ranging from 1400 to 2700 mA·h. NiCad AAs are commonly used by people powering model cars or other (relatively) high-current-draw devices, where the older NiCad technology performs better than NiMH. NiMH AA's designed for high current applications are beginning to become available; these use different construction and have lower capacity (1400-1600 mA·h) than the highest capacity NiMH cells.
in the experience that your digital digicam recosts the batteries by plugging it in (as against removing the batteries and putting them in a battery costr), no remember what the supply of the cost voltage is (AC adaptor or sunlight cellular). you purely ought to have a costr on the astonishing voltage and up to date output, with an adaptive plug that works on your digital digicam. those AC adapter costrs convert AC to DC in the previous than sending it on your kit. And, a sunlight cellular basically places out DC, besides.
It sounds a little scary to me. get the book getting started in electronics, they used to have it at radio shack for $5 or so Then get a multimeter and learn how to use it. In the mean time don't plug anything into the wall, unless it goes through a transformer first that takes the voltage way down. It should say like 250milliamps and 5 volts maybe. Then its ok to play.
It will work fine. What you're describing is a simple parallel circuit. As long as the positive and negative leads don't touch, you should do just fine. One word of caution, you should limit the charge current with either a resistor or a current regulator. NiCds and NimHs should be charged at 1/10 their amp/hour capacity for 10 to 14 hours. Example: A 2200 mAh AA cell should get 220 ma for about 12 hours. Also keep in mind that this pack will only give you about 4.8 volts whereas 4 alkaline AAs will give you 6 volts.
