What is the best citrus fruit to make a battery out of?
Well, in my science experiment, apple is the best fruit battery, then the lemon, then the orange. Remember to change the V--- on the left of the voltmeter and make sure it's 2000m.
If you have no battery acid in the battery yes it can no longer hold or maybe hold for very little time hold charge inside of the battery You need battery acid to keep the cells charged and not to be dryed out. Good question
How can you recharge a cell phone battery?
1]- Open your mobile cover.
2]- Take out your battery.
3]- Take two to three fresh leaves of peepal/pipal/ashwattha tree.
4]- Touch the stub of these leaves on your mobile battery terminal for a
minute.
5]- Clean the mobile battery terminal with the soft cloth.
6]- Put your battery again in your mobile and switch it on.
7]- Now you can see the result.
8]- If required repeat the process with fresh leaves.
PS- Works with any cellphone battery and not only with NOKIA
The above is completely untrue! You can't charge a mobile this way, not even with fruit or potatoes can you get enough charge on the battery. See
http://www.hoax-slayer.com/peepal-leave-phone-charge.shtml
What you can do is remove the battery and hold it in the palm of both hands for a few minutes to warm it up. If you are lucky the battery will regain a minute amount of charge to enable you to read a phone number on it, unless the battery is completely dead, but you probably won't be able to make a call or have it switched on for more than 30s.
There are different types of batteries, made from different materials. As an example, a car battery usually uses lead, and sulphuric acid as active ingredients - as well as plastic separators to keep everything in place.
The battery was invented in 1800 by Alessandro Volta. Batteries were invented in order to power objects that needed an electrical current and also needed to be portable.
Does a battery last as long when it is recharged?
Ni/Cd or Nickel Cadmium rechargeables and many of the metal hydride batteries recrystallize as they heat and cool due to the action of the electric charge. This affects their ability to store charge. Lead acid batteries develop sulfur based corrosion on their metal plates and this affects their ability to recharge. Lithium batteries don't seem to have this effect to the same degree, but do eventually "age" as in this article (see link below).

The short answer is yes, batteries like almost everything else have a limited lifespan. Different batteries have different lifespans and care instructions, so pay attention and choose a battery product with the best lifespan where it matters.
What is a basketball's main components?
The four main components of a basket ball are the cover, the stitching, the lining and the bladder. The surface of basket balls or coverings are made up from synthetic leather and not full grain leather (as used in the past) because leather has a tendency to absorb water causing the ball to become very heavy. Synthetic leather is typically made from polyurethane and poly vinyl chloride. DIS DUDE IS GAY
How do you know if your golf cart batteries are bad?
If you have a manual charger follow the charging instructions. After a full charge, do an On-Charge Voltage Test. Get your volt meter out and set it to 200v dc with the charger on. We will be checking individual battery voltages, start with the #1 battery (where the positive lead goes to the cart) placing the positive lead of the voltmeter on battery positive and the negative lead of the voltmeter on battery negative, move down the line until the last battery. For 36v carts with six 6v batteries we want each battery to read at least 7.0v. For 48v carts with six 8v batteries were looking for at least 9.3v on each battery. Put your safety glasses and safety gloves on. Remove all battery caps. Get your hydrometer out and start with the #1 battery take your sample from each battery cell and write it down. You should have readings of 1100 to 1300, 1100 being close to water and 1300 being acid. Start with the #1 battery. If there is a difference of 50 points or more between cells you have a bad battery. Here is an example of a good battery. 1265 1275 1265 Here is an example of a bad battery: 1265 1175 1265
What is a battery in baseball?
Because like a battery they are the ones that make everything go. Every play in baseball starts with the pitcher (pitching the ball) and the catcher (giving signs and directing the defense) -- If you dont have the pitcher and catcher, you cant play baseball.. kind of like if a car doesnt have a battery it cant go anywhere
How long would I charge a 4.8v 400mah air soft battery?
Well what you do is you get the mAh and divide it by the output of the charger.
Ex
1100mAh/20output=5
So that was an example and i got 5 hours.
Hope This Helped!!( :
How long does a battery on an electric paintball gun last?
It depends completely on the Paintball gun and how fast you fire it, if you keep it on between games, and the battery voltage and type. I would estimate a 9v in a tippman may last two straight days or so without firing.
Why is it not a good idea to throw used batteries in trash?
if they get breached the chemicals in them will poison the environment

What are some ways to increase your track and field running speeds?
To run faster, you have to practice at faster running speeds. No shortcuts, just good ole hard work?
One of the very best ways to improve running speeds is hill running. Run up hills, walk down, repeat. These build the strength you need for faster running without the wear and tear arising from high speed.
If you want to add weights to your running training, a weight vest provides many benefits.
It most likely means you have a short to ground somewhere. You don't want wires getting hot, unless you want an electrical fire. If you're not comfortable checking electrical systems, then get it checked out ASAP.
What is the best way to increase running speed?
The best way to is add some more speed to your workouts every other week. Don't add too much speed - a quarter mile per hour more will get you a long way. When you add the speed every other week, your body will not get too strained and you will be able to get in a better condition slowly but steadily without over training.
Can you bring batteries on an airplane?
you can take normal AA or AAA or regular usage batteries. Not necessarily Car batteries as they contain acids and stuff.
What happens if you add more batteries to a circuit?
Depends on how you add them. Added in series, the voltage will increase, maybe to the point of damaging the LED. If the LED survives, it will shine brighter.
Added in parallell, the LED will shine the same, and will be able to shine longer before draining the batteries.
More often than not batteries corrode from being in an object for long periods of time, and the contents leak and damage the object the battery was in. The only time a battery will actually explode is when it is subjected to high levels of heat.
What is wrong with your car it only clicks a lot when trying to start but does start with a jump?
clean the battery terminals with baking soda and water. them jump it
A battery consists of five dry cells connected in series if the voltage developed by the battery is?
Approximately 7.5 volts, under no-load conditions, assuming that each cell is exactly at 1.5 volts each (which I assure you, it doesn't really happen that way in the real world, but it's close enough).
When cells are connected in series, the voltage is the sum of all individual voltages. In this case, with 5 cells in series (each at 1.5V), the total voltage would be 1.5V*5 = 7.5V
What are the disadvantages of rechargeable batteries?
They must be replaced
once you have used the non-rechareable batteries they Carnot be used again
