There is a way of getting a but more power out of almost dead battery's and that is by rubbing them the friction warms them up and gets a bit more out of them. you can do this with 1 battery as well.

What are two examples of voltage sources?
batteries and generators
How many AA batteries will you need to make a 100 watt light bulb last for two weeks?
Depends entirely on the batteries - all types and brands will have a rating, usually in mWh - you need to work it out from that. You also need to allow for the rated voltage of the lamp. Educated guess - very many thousands.
Explain why a 24v system that runs off of 4 batteries which includes a 12v feed- that's powered by two of the batteries are getting no charge from the alternator.. the other two are charged well.?
With the batteries in series, the alternator provides the same current, and therefore the same charge to all the batteries. The alternator can take no account of any current being drawn from the 12V take off point. Part of the charge current is being fed to the 12V load and not to the batteries. Therefore, the 12-24V batteries are being fully charged while the 0-12V batteries are being partially charged. Over a period of time, the difference between the charge levels will become more obvious.
How do you connect two 12 volt batteries into a 24 volt hitachi ex60 excavator?
Connect the two 12 volts batteries in Series. Battery 1 & 2. Connect the negative post (-) of battery 1 to the negative (-) ground cable. Then connect the positive (+) post of battery 1 to the negative (-) post of battery 2. Connect the positive (+) post of battery 2 to the positive (+) cable. You now have 24 volts as the batteries are wired in series.
Who is the discoverer of electricity?
Electricity was first noted by the Greeks over two centuries ago. They found that rubbing items such as animal fur and amber created an attraction between them.By the 1600s, a great number of experiments and discoveries had occurred, including the naming of the phenomenon by the Englishman, William Gilbert in 1600. He called it 'electricus' in his ground-breaking book; "Magneticisique Corporibus" (trans; On the Magnet). Gilbert was fascinated by the concept of magnetism and made many of the earliest, proven discoveries in the field.The word 'electricus' derives from the Latin word ēlectrum, which, in turn, came from the Greek word ēlektron for amber, the very material the the ancient Greeks used to generate static electricity. In this sense, Gilbert gave credit for the original discovery to the ancient Greeks.Further, Benjamin Franklin certainly did not discover electricity or lightning.
How is static electricity generated?
Static electricity is generated by rubbing two nonmagnetic objects together.
Why do charges appear on rubbing two objects together?
because the rubbing creates static, this static is a type of electricity
What kind of electricity can be caused by rubbing two materials together?
Static
Can the body produce two much electricity where the batteries in watches can go dead?
No
How static electricity produced?
friction. two objects rubbing against each other.
How could you increase a magnets power without electricity?
By rubbing two magnets together.
Why does rubbing wool against plastic create static electricity?
Rubbing wool against plastic doesn't actually "create" static electricity. However, rubbing wool and plastic together does increase the surface area of the two materials that are coming into contact. When this happens electrons are exchanged between the two surfaces creating an imbalance. It is this imbalance of electrons that we see as static electricity.
Give an example of two renewable energy resources and how they make electricity?
The two most obvious are wind and sunlight. The wind will turn windmills which are attached to generators. Solar cells contain chemicals which produce electricity when sunlight hits them. This electricity can be stored in batteries and used when needed.
How can static electricity be generated?
The most common method is by rubbing two different substances together.
How could you increase a magnet's power without using electricity?
By rubbing two magnets together.
What are the two types of electricity describe each?
There are two types of Electricity, Static Electricity and Current Electricity. Static Electricity is made by rubbing together two or more objects and making friction while Current electricity is the flow of electric charge across an electrical field.not sure of answer but hopefully its correct
What causes static electricity to build up?
A static charge builds up when two things are rubbing together.
