Batteries

It's not healthy, but yeah. The trouble with a charging battery is hydrogen buildup from lead-acid (car) batteries.

Why? Because people needed a way to store electricity. The battery was invented around 2,000 years ago if you believe the Baghdad battery discovered in 1936 was a real battery. The Voltaic battery was invented in 1780. The Rechargeable Lead Acid Automobile Battery we use today was invented in 1859.
i think they invented batteries because back then people did not have electricity and they needed some kind of elecricity that would power things and that would be helpful for light and that would be helpful for things that needed to be powered for electricity jessica lampmer 3rd grade
Batteries were made for electricity storage.

it's only good for one day, but don't use it to much couse u might run out before the end of the day.

positive, sends out electrons, is live, Negative, grounds it (where the current ends up)

mAh, milliampere-hour, is used as an informal measure of energy stored in a battery - the product of the current (in mA), and how long this current can be sustained (in hours). More mAh (or Ah) is therefore better.

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.

The popular battery type are AA, 18650, AAA, 14500, CR123A, etc.

One is on the vault the other is by that big old tv

hit ur psp with a hammer with full force it will break open, take out the battery if it survived somehow n throw rest of the psp away.

No, a CR1620 battery cannot replace a CR1632 battery. The numbers indicate the dimensions and capacity of the batteries: the CR1620 is 16mm in diameter and 2.0mm in height, while the CR1632 is also 16mm in diameter but 3.2mm in height. Because the CR1620 is thinner, it may not fit securely in devices designed for a CR1632, potentially leading to poor contact or malfunction. Always use the battery specified by the device manufacturer for optimal performance.

It can be dangerous, but it is possible. I have lost chargers and had to do it. But I wouldn't recommend it unless you pay close attention to it. The way I do it is I take a phone base. (A cordless phone base). I have 2 pieces of tin foil. I fold both pieces of tin foil so you have 2 long skinny pieces of tin foil, I then place each piece of the tin foil on the metal charging pieces of the wireless phone base. Then place one piece of tin foil on the - and one piece on the + of the battery. I then tape the tin foil to the battery and let it charge. Make sure you pay close attention to the battery so it doesn't over charge and start a fire.

Also, if you have a computer, you can take a USB cord and cut off the part that you would connect to a device (not the USB piece) then carefully separate the red wire and the black wire from the rest, Remove the casing from the wires. Place the red wire on the + on the battery, and then place the black wire on the - on the battery, then tape it on and let it charge, pay close attention, if it gets hot then you did something wrong and immediately remove the battery.

They will most likely not work. The best thing to do is to put it into uncooked rice in a plastic bag for a few days. It doesn't always work, but it worked when my phone got wet.

Jewelry is usually made of highly conductive metals and could easily short across the battery terminals if the jewelry comes into contact with them.

Energizer's, Duracell's, Rayovac's, & most Radio Shack & CVS Pharmacy brand are made in the USA. The CVS Pharmacy brand are made to look like Duracell's, and they were made in the USA leading me to believe they could be made by same, they have the same heft to them unlike some of the lower-priced brands. Walgreen's, Sony, are Indonesia, Sunbeam & AC Delco are China.
Some made in USA. Some Singapore and japan. Barely any are made in China

Every motherboard includes a battery, as well as several other components. The battery is there because it powers the computer. Most batteries have between 2 and 4 hours of life before they have to be plugged in.

1. Carbon zinc Battery

2. Alkaline Battery

3. Mercury Battery

4. Lithium Battery

work done=ev.

1electron=1.6x10^-19

therefore, 1.6x10^-19 X 12

The answer is 1.9x10^-19

The seven physical fitness batteries is as follows: Shuttle runs the 5.50 meter dash, Sit-Ups, Sit and Reach, Arm flex hang, Standing long jump and 12 minutes long distance run. The test is used to simply test your strength and endurance.

Either one, depending upon the type of battery. You can get Alkali Batteries for your toys and flashlights. Car batteries contain acids. It requires one or the other to create the ionic differences that produce the current flow.

The 960 mAh battery rating is an eight-hour rating. This means you can expect eight hours of operation at 120 mA. Even though mAh means milli-ampere-hour, the rating is non-linear, and it is normalized to an eight-hour rating, so you should expect somewhat less than one hour of operation at 960 mA.

Keep in mind that this is a relativistic rating, intended to be used to compare similar batteries with different mAh ratings. Actual performance could vary

The D-LR20 is a single use 1.5 volt alkaline "D" cell. There are a number of manufacturers of these cells, and they carry many brand names including Sony, Panasonic, Memorex and more.

No two path

There are at least two ways to interpret this question. The most likely case is that you are simply asking why batteries need to be inserted into a preexisting device, such as a portable radio, with their positive and negative contacts oriented in a particular way. The reason why batteries need to be oriented in a particular way is that most electronic devices require that the current flows through them in one specific direction to work properly. If it does not, the devices will not work, and likely will fail, perhaps in a spectacular fashion. (Current [electron flow] is from the negative to the positive terminals of the battery.) Devices that consist of a simple resistive element like an incandescent light bulb (not an LED), generally are not actually sensitive to the direction of current flow, and will work if the batteries are inserted backwards, although the mechanical contacts in the battery compartment may not touch the battery ends properly. If you are asking why batteries in general need to be placed in a particular place within an electronic circuit, then you need to take an entire course in electronics just to get started on the subject!
