Batteries

Either the battery has a dead cell and needs replacing or something is on pulling power from the battery.

If yo uare tired of paying the high prices for batteries you may be wondering which companies sell rechargeable batteries. Rayovac, Duracell, and Energizer all sell rechargeable batteries.

If you only do this once, not much of a difference in battery performance should occur. However, if you leave it on (doing nothing) for too long many times, some battery problems will arise.

Yes the Dollar Tree does sell batteries.

One of the best ways to recharge batteries is to do so only until the battery is fully charged. Most battery chargers will have indicator lights that let you know the batteries are ready. Remove the batteries from the charger instead of leaving them on for an extended period of time after charging is complete. Overcharging batteries will decrease their life. Plan ahead for an optimum time to charge batteries, and set a timer to remind you to take them off the charger.
Some types of battery can be recharged (called secondary batteries). Others cannot (called primary batteries). You recharge a battery by connecting it to a power supply set to a higher voltage than the battery, usually through a current limiting resistor, connecting it to a special purpose power supply called a battery charger. To avoid damage to the battery, there are limits to how much current you can put into it, and this limit changes as the battery charges. These conditions are different for each type and size of battery. Consult the manufacturer of the battery if you need details. If you are actually asking "How is it that batteries can be recharged?" that is a different question. simply, batteries generate current by way of chemical reactions that generate free electrons that constitute the electric current output. Secondary batteries have a type of chemical reaction that can be driven in the opposite direction by applying an external current.

Brand names do not perform any better than cheaper brands. The only important factor in selecting batteries is that they are labeled as alkaline batteries and are not heavy duty. Heavy duty batteries are made poorly and don't last very long.

Using a remote control similar to those ones used to turn on electronic devices. The infrared rays can switch the light bulb on, since it has a small transistorised circuit that can actuate a tiny relay to put the light bulb in series with the electric circuit.

Depends on the drain.

if the drain is 1500mAh it'll laso one hour before the voltage drops too low.

If the drain is 500 mAh it'll last 3 hours.

150mAh, 10 hours

3000mAh, 0.5 hours.

cellphone batteries are made of LITHIUM ions. u all must have noticed the symbol "Li+", on the battery which denotes lithium ions. cellphone batteries are made of LITHIUM ions. u all must have noticed the symbol "Li+", on the battery which denotes lithium ions.

We searched on "batteries freezer" and also looked at several battery manufacturer's web sites to find the answer to this question. The search results led to a very detailed frequently asked questions (FAQ) page about AA and AAA cell batteries, as well as its related battery myths page that provided a plethora of information about batteries. According to these sources, storing batteries in the freezer (or refrigerator) will make them last longer, but it depends on what kind of battery you're using. And in the long run, it may not be worth the hassle. For alkaline batteries (the most common kind of household battery), putting them in the freezer will extend their shelf life by less than 5%. And cold batteries can't be used immediately -- you have to wait until they've warmed up to room temperature first. If you need those batteries for a flashlight in an emergency, this could prove problematic. When stored at room temperature, alkaline batteries retain 90% of their power, and the average shelf life of alkaline batteries is five to seven years. For NiMH and Nicad batteries (often used for electronics), storing them in the freezer might be more practical. These kinds of batteries lose their charge after a few days when kept at room temperature. But they'll retain a 90% charge for months if you store them in the freezer. Just like alkaline batteries, you'll need to wait until they've warmed up before using them. However, this isn't a problem when you need new batteries for your digital camera or other electronic gadget. Battery manufacturers tend to agree. Kodak says "refrigeration is not necessary, nor is it recommended" and "freezing is not recommended" for its alkaline batteries. Duracell advises: "Do not refrigerate Duracell batteries. This will not make them last longer." Both recommend storing batteries in a cool, dry place.

Here are some tips to keep your iPod charge lasting longer.

- overcharging kills the battery. Charge it only when you need to.

- make sure apps are closed. If you want to make sure they are completely closed turn off your itouch, turn it back on bit leave it in sleep mode.

- lock your itouch. Aka, put it to sleep. It saves a lot of battery.

- if you select a playlist and sleep your itouch then you will lose just about 1-2% battery life per hour. Don't change or interact with your itouch. It will use more battery that way.

- simply give your battery a break. Sleep it or run it off for an hour or so a day without using it. It will cool down the battery and save juice.

- let it cool off. The battery needs a break. Like a computer the battery can overheat and lose battery fast it die.

- don't use a cover that suffocates your device. Let it breathe. Take off the cover if your using safari or a game. The battery will heat up and suck battery if it cannot breathe through the case.

- turn your itouch to airplane mode. It will turn off most battery sucking apps and processes.

- once every two weeks or month charge your itouch all the way to 100%. Then run music or a game or both until the battery empties and the itouch goes to sleep. Once it does let it breathe and leave it for an hour or three. Then charge it all the way to 100% but do not use it while it is charging from 0-100%. This will reset the battery and will make the battery last longer during uses as well as it's life as a battery. This is probably the best tip in saving and conserving battery life.

I hope these tips help.

Ah stands for Ampere hours. It is a measure of capacity, how much electricity the battery can hold.

Eg: A 12 volt 5 Ah battery can deliver 12v at 5 amps for 1 hour. Or 12v at 0.5 amps for 10 hours and so on.

Remember. Voltage is supplied by the battery but current/ amps are drawn by the appliance. Power in watts is calculated as volts x amps. So for instance a 12 volt bulb drawing 2 amps is: 12x2=24 so it is a 24 watt bulb. so on a 12v 5ah battery it will burn for about 2.5 hours. This is why car batteries are quite big for only a 12 volt battery, the massive current drawn by just turning the engine would flatten a small battery, and probably still wouldn't start even then.

They don't. It's a chemical reaction. Which means that primary batteries ( like Duracell) convert stored chemical energy into electrical energy meaning flowing electrons. As you use a device, the electrons are used to power it. Over time, the chemicals in the battery have no more electrons to give and the battery "dies,"

Every kind of battery has its own history on how they stop producing electricity.

Basically, as the first answer stated, its a chemical reaction, but none of them stops the same way.

They're rated at 1.5v, but, as you may know, when brand new, they supply a little more, like, 1.7v, and supply only 1.3 when they're running out of juice

9 volts (that's what the 9 means)

Further Explanation:

This sounds like a silly question, but a battery is not always at its' nominal voltage. In general, non rechargeable batterys of the same type will have a higher terminal voltage than rechargeable. Over time, as the battery becomes used, its' voltage will sag until it is no longer useable.

Rechargeable battery cells are usually rated at 1.2 volts. When fully charged, they will be slightly more than this; as they age, they may become less. For cheap rechargeable 9 volt batteries, the manufacturer might use 7 cells - 8.6 volts; others might use 8 for 9.6 volts. Non rechargeable usually have 6 cells rated at 1.5 volts each (6 x 1.5 = 9).

well, generally, the more cells a battery contains, the more capacity a battery has. the batteries have different working hours because of the number of the cell. what's more every cell has a "3.7 V normal volt" and the maximum volt is 4.2V, the Volt of a battery finally depends on the number of the cells and the series circuit/parallel circuit. i

It actually depends on what you're using it for. For example, a camera will drain more energy than a remote control.
Approximatley 6 months to a year depending on usage. If you, say, listen to a sports radio an hour a day every day, it'll probably last 3 months. If you have a tv remote and use it every day, probably a year. The main difference between Energizer and generic is the self discharge rate. The self discharge rate is how much power a battery cell loses even if its not in use. The avergae self discharge rate is between 8 and 20 percent of totally power over a year period. Energizer is closer to 8 while generic is closer to 20.

Wash it out with plenty of water and go immediately to the hospital.

The acid in a battery is sulphuric acid. It is highly corrosive and hazardous to touch. Acid spills must be carefully cleaned with products which neutralize the acid. Personal protective wear, at a minimum gloves and face protection, should be worn when cleaning acid spills.
