A potato battery is an electrochemical battery, otherwise known as an electrochemical cell. An electrochemical cell is a cell in which chemical energy is converted to electric energy by a spontaneous electron transfer. In the case of the potato, the zinc in the nail reacts with the copper wire. The potato acts as a sort of buffer between the zinc ions and the copper ions. The zinc and copper ions would still react if they touched within the potato but they would only generate heat. Since the potato keeps them apart, the electron transfer has to take place over the copper wires of the circuit, which channels the energy into the clock. Presto! You have potato power.

Car battery does not hold charge in cold?
The cold weather slows down the chemical reaction that goes on inside the battery.
Does the DS have better battery life if you plug it in while playing or if you only charge it when the battery is low?
You ant to charge the lithium Ion battery before the battery reaches a 20 percent charge, so when the light goes red.Charge it while you are playing so you can sit there with no battery loss
Can you charge a battery while still fitted to a car?
yes..... Simply disconnect the positive and negative cables from the battery,then clean the posts on the battery and the inside of each terminal with a post cleaner (inexpensive tool found at parts stores)or a wire brush until both posts and both terminals shine like new. Then just connect the battery charger directly to the battery posts red goes to positve(+) black goes to negative(-). Once the charger is finished charging the battery then turn off the charger and remove the connectors..then put the battery cables back on the battery and try starting the car...
What is a potato when it goes bad?
A potato gone bad. Garbage. Wasted money.
Can a laptop battery become overcharged while using it?
A laptop battery can be charged while using it, but it would not be likely to become overcharged when the laptop is in use, unless the laptop goes into a sleep or dormant state.

How do stair lifts work when the power goes out?
While there are many stair lifts that might not run when the power goes off, some are battery operated and would still work. There are other kinds that are electrical, but have battery back ups as well that will run when the power goes off.
How is the wiring on a 1979 Ford F-250 alternator red for battery what is the black and white wires for?
White wire is for signal voltage and the black wire sends the voltage to the battery, orange/red wire is your field wire that goes out to your external regulator, also there is a signal wire that goes to your battery gauge inside the cab.
Potato battery or lemon battery?
You can make a battery out of both a lemon or a potato - if you want to see how just do a net search on "potato battery" or lemon battery. In science we have been conducting an experiment to see which of the fruits/vegetables creates a larger flow of electrons- for us it was the potato so it may make a better battery than the lemon. u make it by putting a penny in a lemon and a nail on different sides, then use a battery meter to see how much electricity the object has.
Car goes click click when you try to start but turns over with a boost?
The battery does not have sufficient voltage to start the car when it's cold. Have the battery checked out. If it still goes click click after running the car for a while, have the alternator checked also. A bad battery will not hold a charge and a bad alternator will not recharge the battery, (That is the reason to have the battery checked first). Make sure the connections at the battery are clean and tight.
