"Note: 3V 10mA" vs. "Note: 3V 100mA''?

My wireless keyboard office has a rating of 3 V and 10 mA, while the wireless optical mouse is 3V and 100mA. I was not a science major in my school years: 1) Can you explain the meaning of the difference between 3V 10mA 3V and 100mA? (I used 1.2V 2500mA rechargeable) 2) when the mouse does not work because of 2 x 1.2 V batteries, a battery is measured 1.1V, while the other is 0.9V. Why? Any feedback is appreciated. 3) I use both batteries died to make my mini vacuum cleaner and Vacuum for work hours!

1] The difference between 3V and 3V 10 mA 100 mA is: The first note using your keyboard uses a 3v battery volts and consumes about 10 mA current for function. (which is 10 millionths of an ampere). The second (mouse) Assessment is 3V, but draws 100 milliamps (or 100 millionths amplifier). 10 times more power, but at the same voltage. A good analogy is with a garden hose. If you put the hose on the slow, a small amount water passes through. When the pressure is increased, more water is passed in the same area. This is the analogy being. 2] Batteries May show tightness, but now they are also important. The batteries can be about 2 volts between them, but later left in them does not to "push" the line voltage.

Battery prices? Duracell? Everready? Energizer?

I need individuals, the exact price please. [1 set, 2 AA batteries] have the exact price of a science project. I need a suggestion. I will choose as best answer or if u give me.

AA is not sold in pairs. The minimum you can buy sets of 4 or 8 or 16 years. The set of 8 costs $ 5.68 at Wal-Mart here in a while. Cal I am sure that prices will change from region to region.

Should I buy rechargeable batteries or a loading dock for my Wii?

I heard that Li / Ni-Mh that come with loading bays longer than AA, but I really want to put skins on the remote, keep them as clean and have a handful of Nice. I also heard of some defects in the loading docks, Ni-Mh battery can only achieve half load (?) In the long term. So what do you think should receive? Any advice?

I have the Nyko Charge Station and works very well. The disadvantage is that it really could not put a skin it because it comes with a new grip again (X2), and has little contact charge to help you, but you can charge 2 remotes at both. I highly recommend it.

The batteries are all .. Energizer brand

Although batteries have greater capacity than either C May 5000, D 10000. But are more expensive. Cheap C and D, using NiMH AA batteries in a plastic tube that fits C or D Cell!

How often you change batteries in smoke detectors?

Whenever it starts and ends daylight saving time, as the battery manufacturers' d like to think is necessary, but the batteries last for 2 years or more? Although the detectors are ways to test the viability Battery? Do you recycle batteries and their toxic components? How many tons of heavy metals are not needed in the waste stream as "fall"?

You do not have to replace twice a year, only proves that (press the test button on the detector). There are ten cells available year, then just test every six months, and should only have to replace the batteries every ten years or less. Much of the scrap metal lighter.

How do I know if an alkaline battery has been shelved for how long?

I've always wondered. Is there a number or alphabet indicates the date of manufacture. Do you have an alkaline battery loses power if left on the shelf for a while?

Each manufacturer has its own code, and is usually some type of 365 days of appointment. But is not usually something you want a consumer to collect easily. Yes, all batteries a little life lost sitting on the shelf. The warmer the temperature, the more you lose. If in doubt, see them all at a price of several meters. May that give an idea of what is in everyone. You can also place them in the refrigerator to prolong shelf life.

I have a Dell Inspiron 5100, about 4 years old. The battery of my current Sanyo is a 14.8V, 12C Lithium-Ion battery that comes with the system of values, and I'm lucky to get 2 hours with light to moderate use. I tend to rarely charge the deep cycle – most of my use is on AC power. On the occasions where you need to use the system on the drums, really need more than 2 hours! I want to find the biggest, baddest drummer out there who will give me time to work as long as possible. Can anyone give me a baseball stadium in that kind of time you could leave a good battery? How do I determine a list of approximate life of the battery data (from now mean nothing to me)? Help, please, all high-tech people smart!

Hi-Cap, which is in turn higher MaH … But the problem with laptops is as follows: Each model is equipped with a different battery and for this reason Hi-battery manufacturers CAP does not mind. Apple, meanwhile all use the same battery (CFP INTEL-mode/model) the Most of what you can get a battery of 9 pm, but the batteries last value of more than 5 hectares, with a twinkle below and WiFi off. With everything I have on my iBook 4.5-5, 3.5-4 on my MacBook. Best laptop for battery life are Fujitsu. Also keep in mind a battery Li-Ion battery is only good for 500 charge cycles … But Dell is not to say anything …
