Batteries
Batteries are sources of chemical energy that are used in circuits to provide electrical energy for a wide range of useful devices. Any questions and answers regarding batteries or other power supplies would be welcome here.

What chemicals do batteries have in them and are all batteries the same?
Depends what kind of batteries
All batteries do the same thing. Have the same purpose and can conduct electricity.
- The alkaline battery can take the square or cylindrical form that we all know so well. The contents are contained safely within a steel casing. The cathode, which is the negative part of the battery, is a compressed mixture of manganese dioxide paste and carbon powder. The center of the cathode is hollow and lines with a conductive separator to prevent the cathode and anode materials from mixing, but allowing their varying electrical potentials to pass from one to the other. The anode is the positive part of the battery and contained within the center of the cathode. It's a gel of potassium hydroxide and zinc powder.
- The box or exterior of the Zinc-Carbon battery doubles as the anode, being made entirely of zinc. It contains a mixture of manganese dioxide and carbon powder as the cathode. The cathode floats within a solution of ammonium chloride and zinc chloride dissolved in water.
- Nickel-cadmium batteries are better known as NiCad or rechargeable batteries. They are made of two thin plates of nickel oxy-hydroxide and cadmium which are flattened together and rolled up into a cylinder shape. The nickel oxy-hydroxide acts as the anode, and the cadmium acts as the cathode. The catalyst is the electrolyte fluid which fills the battery, known as potassium hydroxide. This causes an electrical charge to build between the anode and the cathode.
How you get power to TV using AAA battery?
Yes, but you might need a lot of AAA batteries, because they don't have a lot of available power.
Can I recharge all types of batteries using an energizer battery charger?
For each Energizer battery charger, there will be a product specification sheet that will come with the item you purchased or that you can find online. This will tell you what batteries it is compatible with.
How long is the alienware 17's battery life?
Generallythe battery life in any alienware is of a better grade than the ordinary.
How does the potato help in identifying the positive terminal of the battery?
The positive terminal is slightly larger than the negative terminal. I never heard of this potato deal.
What is draining your van battery?
many things can do it suck as junk battery, junk alternator , or leaving anything on in the car
What is a control group for a science fair project on battery life?
Take a battery from each different battery type (prefferably three). Leave those out in the same conditions as the ones being tested when the one being tested is determined "dead", take a voltmeter and compare the control battery with the tested battery.
Why does your wipers run when the key is on and it sits overnight and the battery goes dead?
Not knowing what vehicle you have, you may have a faulty switch or pulse board. Remove the fuse for the wipers when it is not raining until you can get to a garage for repair.
Can you use a 12 volt battery charger to heat water?
Yes it could be possible. There are two parameters that have to be met. You will need a 12 volt DC submersible heater. The wattage of the heater must be low enough so as not to draw more amperage than the battery charger's output can supply. The formula to use would be I = W/E. Amps = Watts/12.
An example would be, for a 120 watt heater, A = 120/12 = 10 amps. If your battery charger has a higher output than 10 amp then you can make the battery charger heat water.
Can a loose battery cable cause a battery to go dead?
Yes. If it is loose on the side that comes from that alternator, then the alt. is not getting the opportunity to charge the battery. So basically you're running your car on pure battery and it will go dead accordingly
What are some chemical reactions that occur around the house?
They occur often in the kitchen and especially the bathroom.
Some of the Chemical changes in a kitchen are:
Baking a cake
Striking a match
Burning toast
Spoiling milk
Sugar dissolving in tea
Printing
baking a cake is not an example of chemical its physical
No lithium batteries don't leak. There the bestS ones to get.
What might be the cause of overnight battery drain in a 1993 GM diesel pickup?
Assuming it's actually a drain and not a bad battery, check for:
-aftermarket electrical equipment such as plow, cell phone, alarm
-door or glovebox not closed
-bad alternator diode (may be intermittent)
-corrosion at starter B terminal
-something else
Can 2700mAH NiMH battery be used instead of 2300mAH NiMH battery?
If it will physically fit in the space, then yes, the 2700 mAh battery should work fine.
How much is bail set for a battery charge in lake county Indiana?
Bail is a variable amount set by the judge in response to several factors and inputs - your criminal record (if any) - the seriousness of the crime - the recommendation of the prosecutor - the noteriety of the case - etc).
What indicates that the charge on the CMOS battery could be getting low?
As far as I know, there is really no advanced warning, until the battery starts to fail. For example, on my computer, after using it for several years, the computer started to be unable to maintain the current time. I eventually figured out that this was a result of a weak CMOS battery.
What colour is terminal on a car battery charger?
I'm not sure what you're asking but maybe its this: Red is Positive (+) and Black is Negative (-).
This is slang for flak, sometimes called AA fire, othertimes known as tirple A (or AAA anti-aircraft-artillery). AA stands for Anti-Air fire. The German name for AA is Fliegerabwehr. The name flak came from the German name Flugabwehrkanone. Which loosely translates as air defense cannon. Others say the name came from the sound of flak making an ack ack sound. 'Ack, ack' does not come from German, but from the alphabet used by British signallers in the First World War. The alphabet involved saying 'ack' for 'a', 'beer' for 'b' and so on...hence AA when transmitted by signallers would be transmitted as 'Ack, ack'.
Both. German 88 also called in basic German Acht-acht, eight-eight and also the British use ack-ack. Although the latter is more likely what is being referred during WWI and WWII, seeing that both refer to AA, with the former being more specific, I'd say, this information just gives more insight of use.
