What is better batteries or electricity?

Batteries produce electricity, too. Probably what you mean is whether direct current (from batteries) or alternating current (from electric companies) is better...\n\nDirect current electricity is better than alternating current electricity...\n\nDirect current electricity produce more work with less energy than when using alternating current electricity...Although, availability of a.c. electrictiy is better than d.c. electricity.

no that is why our electricity is ran house to house in ac.  it is safer to operate ac and also more energy efficient.

Light is faster because electricity has to interact with the atoms it finds as it moves along a wire. Electricity is only a BIT slower than light, but you cannot tell the difference in real-life situations.

Very low, as most of the funtions are controlled by minute electrical impulses, you dont want to be messing around with anything stronger that a AA battery.

Hi there...\n\nProfessional battery equipment is needed to recondition any battery, and the LITHIUM ION are the most deadly .... \nIn battery shops accross the country, the service technicians will generally not TOUCH a lithium Ion. \n Where I am located, there is a shop, and they tell me that they would have to install a fire-brick fume-hood, with explosion proof shielding, and other specialized bomb disposal stuff, before they could work on the Lithium ion batteries.\n As one other answer stated, the batteries, despite being " no memory " unlike Nickle Cadmium batteries, which "remember" being both not fully charged, and not being fully drained, the Li Ion batteries just plain die. Another answer gives you a link to NI-Cads, which is useless. The charging and cycling of Li-Ion and Ni-Cad are completely different. With old Ni-cads, you can use an ordinary capacitor to zap the batteries back to life, once. The professionals use very sophisticated machinery to revitalize older Ni-Cads. Nickle Metal Hydride are in the middle of the pack, with a different set of characteristics.\n  YOUR batteries are the worst.\n\nIf over heated, they will bloat, crack, and gas will escape in a foot long flame  that will cut through solid bone.. ie ... it can ampute an arm or leg if you happen to get in the way. There are reports around the world of people being " burned" and in the hospital, from Cell phone Li-Ion batteries. Cell phone Li-Ion batteries that are bloated are capable of cutting through the side of an airplane, including the hydraulics, frames, and wiring....\n\nUnfortuneately, in your case, you are forced to just replace the battery pack... do not play with it!\n\nIn the future, you might want to charge the battery as often as you can - the battery WILL remember slowly dying by lack of use. If it is always kept charged, it will last longer. People are lazy and don't bother to charge batteries until they " have to ", and this will shorten the life of any battery.\n\nGood luck

Heat drains out battery power. To help them last longer place them in the refrigerator! Keep new batteries in original package, or place them in a plastic bag to fight against moisture. Remove the batteries from the refrigerator 2 hours before using.\nhttp://foodgeeks.com/resources/householdtips.phtml?cat_id=10\nMore info on\nhttp://www.straightdope.com/mailbag/mbattcharge.html

Batteries use the different potential that certain chemicals have. Battery consists of 2 chemicals which potential different are significantly enough to generate voltage difference. Reaction happening in a battery is redox (reduction-oxidation) which allows electron transfer. Positive terminal of the cell has the higher potential.\n\nAs the reactant are all used up, reaction reaches equilibrium. This is when we found out that the battery is 'dead'.

Just use standard. Even though the others recharge. After you use them the charge doesnt hold as long and it becomes a hassle keeping your equiptment working.

No, generally speaking larger laptops use more power, usually because they are more powerful and have larger displays (which takes more electricity).  Smaller laptops tend to be less powerful, less features, and smaller screens, so therefore use less power.\nThis explanation does not apply to battery life as well though, if you are interested in this.  But since you mentioned Energy Star, I'm assuming you are most interested in Energy Conservation, not battery life.  For this, you will be best off with the smallest profile of laptop, the subcompact laptop, if it suites your needs.

depends on how good of a make is it and the ratio of the player is and were it originates from and most of all what kind of batteries does it run best off.there for if its worth as much as it is u should receive as much as its worth.

Take a look at your electric bill.  It will tell you what your average daily electrical consumption is.  You will need some form of electrical production that meets that amount every day.\n\nMost home battery systems use 12 volt batteries connected in series to obtain a high voltage.  Then the batteries are connected to an inverter to produce 120 volts AC.  You can buy inverters that are rated for about 5 kW.  If you have a pair of those, one on each leg of your electrical connection (L1 & L2) it is good for 10 kW of power which should be enough for a most homes.  The reason for being able to handle high power is that sometimes the refrigerator, A/C, stove and TV may be on at the same time and draw a lot of power even if it is for a short time.\n\nThe size of your battery bank will depend on your generating system.  If you can generate continuously, the battery capacity can be reasonably small.  If you are relying on solar and wind energy and have to account for a few days of overcast skies and no wind, the batteries have to be quite large.  Sizing the batteries takes a bit of research.

This is the best answer you'll get -\nhttp://electronics.howstuffworks.com/battery.html

Rechargeable lasts longer in digital cameras and such.  Regular AA batteries will die in like 20 minutes if not before.  They just drain real quick.  Buy the rechargeable and get a battery charger.  They are cheap.

All you really need is a source of high current. A car battery would work fine. The real question is what are you going to use as a "rod" and "flux"  Those are the critical issues.

yeah, both have been done. Neither were very useful, but that may change if solar cells get more effeicient, and batteries get better.

i think its acid..........The kind of batteries you have in your toys and CD player are wrapped in nickel-plated steel. This steel case has a thin plastic coating on the outside. Inside are the three main parts of a battery: the anode, the cathode, and electrolyte. The anode is made of zinc metal, and electricity travels from the anode through a circuit back to the cathode. The cathode is made of manganese dioxide and graphite. The electricity then passes back to the anode through the electrolyte, which is a salt and water solution. Batteries may have other parts inside made of plastic, brass, and other materials. For a look inside a battery, check out this Duracell page.
