How long does a 8800mAh battery last for?
It depends on the laptop. If you have a small laptop like an EEE PC you could see 10-12 hours. If you have a mid-range laptop with a power-efficient processor you could get 6-8, and if you have it in a gaming rig laptop you may see around 3 hours.
Can you use lithium batteries instead of alkaline batteries?
Careful Answer: SOMETIMES. But ALWAYS check the label of the lithium battery in question to make sure it is rated for "1.5v" before attempting to use it as a replacement for an alkaline battery.
Explanation:
Alkaline primary batteries have a nominal voltage of 1.5v per cell.
Lithium primary ("primary"=disposable) batteries USUALLY have a nominal voltage of "3v" per cell.
There are some Lithium primary cells, AA's for example, that have a nominal voltage of 1.5v per cell which makes them a suitable replacement for alkaline batteries.
To complicate matters, however, there are rechargeable lithium-ion cells in the AA format which have a nominal voltage of 3.6v per cell, and more commonly there are "Lithium Phosphate" AA's which have a nominal voltage of 3.2v or 3.3v per cell. Using either of these as a replacement for alkaline batteries would be potentially destructive for both the batteries and the device you install them in.
How do you replace the battery on a Dell Inspiron 1100 laptop?
The old battery will not just slide out. You have to either press the release button or the latch. Then you place the new battery in the slot where the old one was located and you got your new battery installed.
How does batteries hurt the envoirment?
Rechargeable batteries are considered environmentally friendly because although they still contain metals and chemicals that are toxic, they are good for the environment compared to non-rechargeable batteries. Rechargeable batteries often last hundreds of times longer, meaning that less waste is produced and less resources have to be used to replace them.
Also, most other environmentally friendly devices such as solar panels require rechargeable batteries in order to function. Since solar energy is not available all the time (like at night) the power must be stored in a battery, which of course has to be rechargeable. "Environmentally friendly" cars such as hybrids and fully electrical cars rely on rechargeable batteries as an alternative to fossil fuels. Basically, rechargeable batteries cut down on waste and resources needed while making other environmentally friendly devices possible.
Are cr2032 and cr2025 batteries interchangeable?
Nope. I am no battery expert, but I have, in my hot little hand, one CR2025 and one CR2032. The two have the same diameter and both are 3 volts, but the CR2032 has a considerable amount of extra depth. My camera remote requires a CR2025. I have some extra CR2032's laying around for a scale, so I thought I would give it a shot. The CR2032 does not fit.
Where can you buy a battery charger for a Work Force cordless drill P10001?
Your best bet would be meijer.com. However, they are out of stock. That leaves you with a few options. 1. Contact Meijer directly and ask them when they will be back in stock. 2. Try the Craftsman 19.2V C3 Ni-Cad Only 1 Hour Battery Charger 12V- 19.2 Volt. It is available on Amazon. 3. Buy a new drill. I've had my Ryobi for years and have never had a problem with it. You get what you pay for.
What happens when batteries of the same voltage and polarity are connected in parallel?
If you connect both poles of the same battery together, it will make a short circuit, because the electricity isn't going anywhere, just in one side and back to the other, it will cause whatever you used to connect them VERY hot. Electricity is a type of energy, and MOST energy (i say most because I am not 100% positive they have found an exception in this world) will have some connection to heat. But if you plan on doing it, get a lantern battery, one of the REALLY big batteries, and lay a paperclip on the top of it, or some other conductor on both poles of the battery, and back up. And if you are gonna remove it, wear an oven mitt :D
Which stores have replacement watch batteries?
There are many many stores that can do this, but your best bet is to visit your local jeweller or watch store. They have all the equipment needed to do it properly. Even local markets sometimes have a stall there that can do it at a reasonable price.
The Ever Ready company issued a "PP" series of batteries (standing for 'power pack'), and the PP3 was the small nine-volt battery in that series.
When to change cell phone battery?
Changing your cell phone battery is a rare event, and you should look at a few critical points before changing your cell phone battery:
- Does it charge? A battery needs replacing if it does not charge.
- If it does charge, how long does it last? A battery needs replacing if the charge does not last as long as it should for your phone.
- Is the battery corroded or damaged in any way? A batter needs replacing if any part of the battery is corroded or damaged in any way, which could be potentially dangerous when using it.
What is one of the chemicals in a battery?
This varies depending on the specific battery "chemistry" used.
- the old carbon-zinc batteries used - carbon, zinc-mercury alloy (with iron grains contamination in the zinc), zinc chloride paste, water, manganese dioxide (to suppress hydrogen gas formation), porous paper separator
- modern alkaline batteries use - carbon, zinc, potassium hydroxide paste, water, manganese dioxide (to suppress hydrogen gas formation), porous paper separator
- lead-acid batteries use - lead, sulphuric acid, water
- nickel cadmium batteries - nickel oxide hydroxide, cadmium, potassium hydroxide paste, water, porous paper separator
- lithium manganese batteries - lithium, manganese dioxide, lithium perchlorate paste, propylene carbonate, propylene dimethoxyethane, porous paper separator
- lithium ion batteries - lithium nickel manganese cobalt oxide, carbon, lithium perchlorate paste, ethylene carbonate, porous paper separator
- etc,
How long will a laptop battery hold it's charge?
A lot of factors have an effect on the quantity of time that a transportable computer battery can deliver energy ahead of it has to be recharged. These
elements include the configuration (processor, memory, and so forth.), kinds of applications becoming run and display brightness.
Dell uses market regular benchmarks for battery run time claims. For far more information on battery run occasions and benchmarks, the white paper,
"Understanding Battery Life in Transportable Computers" is obtainable at:

Is an AAA battery an rechargeable battery?
There are rechargeable AA batteries that are sold.
One should NOT attempt to charge regular AA batteries. This can result in the batteries leaking or exploding. Charging regular batteries can result in injury or fatality in a number of ways including fire. If they do not say rechargeable then they are probably not chargeable.
What are the effects of wasting electricity?
power demand will increase in generating stations
tariff will go up
savings of energy for future is very important
What type of managemnet style do you work best with?
There are three philosophies of management that I subscribe to:
1. Situational Management - the style of management needs to adjust to the situation.
2. Management by Exception - typically 80% of an organization will run itself, so the manager needs to focus on the exceptions (the areas that are having problems).
3. Ideal Management - a manager should groom his organization to run itself. Remove the obstacles that prevent workers from getting their job done or that make them inefficient. Management is a non-contributive overhead for the company and should be eliminated whenever possible.
if you constintly run what you have the battarie in it takes about 8 or 9 days for it to start to go away if you put the battarie in a flash light you see how long it takes because of the light getting dimmer.
They last about 4 hours but depending on the size. If litholeom then much longer like maybe 7-8 hours. But if rechargeable then about 3 hours. Battery life is dependant on use - the more you use it the less time that it will last
4 hours
Depends on what it is powering. One AA will last for months in a clock.
They can last months in any small appliance that doesn't have many electronic objectives. Clocks do one thing, slowly, constanly. Others do more than one constanly.
The average AAA Duracell battery can last about 19 hours in a flashlight. If you test it in a clock, it can last much longer, because clocks are low drain power systems. If placed in a high drain power system, like a camera, it may only last up to about 10 hours. YOUR WELCOME! :D

It depends on the size of the battery and what you're using it on. For example, AA Duracell batteries in a flashlight. Your question is terrible, give more info.
Is there a cordless battery or rechargeable hair dryer available for purchase?
yes ther is
www.batterypoewred hairdyer.com like ayit
No it is not. Log onto eBay or amazon and you'll find a real rechargeable hair dryer just launched by tek maker co.
I considered importing the Tek Maker dryer and thus had a sample sent. In my opinion the battery does not last more than about 12 minutes, takes hours to charge and is nowhere near as good in performance as the Ioneat gas/battery driven portable dryer found at www.ioneat.co.UK
gas? is it safe ?
Change battery in a gruen wrist watch?
The battery in a wrist watch is replaced by removing the retaining screws and prying the bottom off. The battery is then slid out of place and a new battery put in.
Can 10.8v battery replace 11.1v battery?
yes it can, the replacement battery's voltage must not lower than the original battery
How long will a battery last at 20ah draw?
5 hours till dead flat but you really only want to take it to 50% so 2.5h
Where is energy stored in batteries?
Within a battery, energy is stored as chemical energy. When the battery is attached there is a chemical reaction happening inside having to do with a flow of electrons that gives the battery the power to make something work.
