This is the dried crystals of electrolyte that leaked out when the batteries died. They can be corrosive to the electrical parts of the device or can cause chemical skin burns. Such leakage is rare with modern batteries as they use steel jackets to contain leaks, but they still sometimes happen. After disposing (recycling if possible) of the dead batteries, this powder should be cleaned off all device surfaces that you find it on with a dampened paper towel or cloth then the surfaces wiped dry.

If the powder got on electronic components sometimes they are damaged irreparably, in this case contact the company that made the batteries that leaked as many have a repair/replacement policy for damage to equipment caused by their batteries.

LED Light Bulbs are based on light-emitting diodes; the most notable advantages of LED light bulbs over conventional light bulbs are LED light bulbs last upwards of 50,000 hours. Additionally, LED light bulbs consume very little electricity. They are also shatterproof, run cool to the touch, and contain no mercury or hazardous substances.

Duracell offers good quality and easy to use rechargeable batteries. There are generic brands of rechargeable batteries out there but they are often unreliable and wear out very quickly.

A 2200 mAh (milliampere-hour) battery carries about 30% more charge than a 1700 mAh battery, but there may be other factors to consider in deciding which one is better for a particular use.

A fully charged battery that is rated for 2200 mAh should be able to deliver, for example, 100 mA (milliamps) of current for 22 hours.

Simply because of the materials they're made from. There will always be degradation in rechargeable cells. Older Nickel Cadmium batteries suffered from 'memory effect' - which depleted their capacity gradually over time. Nickel Metal Hydride batteries don't apparently suffer this effect, and therefore last much longer.

Smallest to Biggest in each category.Cylindrical-AAA < AA < C < DPrismaticLantern < 9-VoltThese are the most common batteries and generally the only ones consumers ever use.

Not long, but its not the apple that limits the life it is the amount of metal electrode surface available that the electrolyte in the apple can corrode that limits the life. Once the metal corrosion stops the battery is dead.

You cannot make a 6 volt battery into a 12 volt batter, but you can make a 12 volt battery out of two 6 volt batteries. Connect two 6 volts batteries together in series and you have 12 volts. Please define "in series".

A battery eliminator is a device that can be used to power a piece of equipment that is usually powered by batteries. It can be used to power things like radios, toys, and small electronic appliances.

Exide batteries are manufactured by Exide Technologies, one of the world's oldest and leading manufacturers of lead acid batteries based in the US with global operations. W. W. Gibbs founded the company in 1888 under the name Electric Storage Battery Company, purchasing patents from inventor Clement Payen. The first battery carrying the Exide label was made in 1900. Exide means "excellent oxide".

Who could say for sure what battery it takes? One thing is for sure, Canon never manufactured a DL-9000 camera. You can also find Nikon DL-9000 and Kodak DL-9000 cameras out there. ALL of these cameras are fraudulent knock-offs. They seem to be similar to the insides of a cardboard camera inside of plastic body. Please do not associate the image quality of this camera with legitimate cameras.

Lithium Ion batteries can be viewed as a balloon that gradually gets smaller. You can blow it up and let it down all you want, but over time you lose capacity. You can damage a lithium cell by too rapid charging but Apple prevents that. Mostly a lithium cell simply ages. If you keep your iPad in the freezer the cell probably would last longer, but I suspect you'd kill the screen. Best idea is replace the battery when it doesn't last long enough. Should be 3-5 years depending how much time you need.

12 hours maximum

The clipses are on the sides facing outside. Insert a small screwdriver on one side, and pull the cap.

Carefully, but firmly, insert a fine tip screwdriver between the bottom cap and the body of the thermometer (on the side that has the on/off button). Do not ever use a knife or cutting edge tool instead of the screwdriver. Once inserted (less than 0.5mm deep) the screwdriver should have unlocked the cap. Even so, you will have to firmly grip and pull the cap with your finger tips.

I believe you can, it may work. I wouldnt try it might explode!!

Braun 5742 disassembly:

1. Remove the cutter screen.

2. Remove the cutters.

3. Use a #8 Torx screwdriver to remove the two screws on the cutter frame. Lowes hardware sells a really cheap Kobalt brand Torx screwdriver with multiple Torx bits. Note that there are small O-rings (orange colored on my shaver) around each screw which you are removing now, around other screws which you will remove later, plus O-rings around the metal power jack posts. Pay attention and do not lose these O-rings. If you do lose one and can't find it, use a small dab of contact cement when reassembling your shaver in order to achieve the same watertight seal where the missing O-ring would be.

4. With the sideburn trimmer retracted, pull on the entire cutter assembly. It helps to pull somewhat more on the side of the cutter frame adjacent to the sideburn trimmer assembly, or at least pull that side of the cutter frame assembly slightly loose first by about one eighth of an inch. It may take some tugging to pull the cutter frame off of the shaver body since Braun uses some sort of silicone based sealant compound to assure that the razor is watertight. Then simply pull off the entire cutter frame.

5. Clean the gasket areas of the cutter frame and shaver body with Q-tips and isopropyl alcohol so that these mating surfaces will be nice and clean when you later reassemble your shaver. A can of compressed air is also handy in order to assure that there is no lint remaining on these mating surfaces. And yes, put on your eyeglasses so that you can see what you are doing!

6. Insert a very small jewelers flat head screwdriver into one of the rubber plug covers over the hidden screws at the rear end of the shaver body and pop out the rubber cover. The screwdriver should be inserted along the side of the cover closest to the power jack. Alternatively you probably can use the straightened out end of a small paper clip instead of a jewelers screwdriver since the rubber plugs are purely cosmetic in function. Do the same for the other rubber plug.

7. Remove the two screws hidden under the rubber plugs.

8. Hold the shaver horizontal and use the eraser end of a pencil to push on one or more of the metal posts in the shaver's power jack. The guts of the entire razor will slide forward inside the shaver case towards the cutter end.

9. Grasp the cutter head end of the shaver guts and simply finish pulling the guts out of the shaver case.

10. Remove each NiCad battery by prying up on the end of the battery which is nearest the plug end of the shaver guts. The pin built into the end of the battery will unsnap and slide up through the channel of the shaver's battery terminal. Note that there is a small band of double-stick adhesive tape underneath the batteries. Roll the battery back and forth and use a jewelers screwdriver to pry the tape away from the battery. Then extract the battery. Do the same for the other battery. Use the jewelers screwdriver to reposition, if necessary, the double-stick tape back onto the frame of the shaver.

11. The NiCad batteries create a fair amount of oxidized film over a few years on the battery posts and on the battery terminals inside the shaver. This film prevents electricity from easily flowing between the battery posts and the terminals. An indication of this condition is that your razor never indicates that the batteries have fully charged. Clean the ends of the batteries by thoroughly wiping them with a cloth slightly dampened with isopropyl alcohol and then clean again with a dry portion of the cloth. Do the same, using Q-tips, for the battery terminals in the shaver frame.

12. If you have already bought replacement NiCad batteries, install them now. If you wish to test the original batteries in order to see if they will take a full charge now that you have cleaned off all oxidation, reinstall the batteries and press the shaver's power button. The shaver's charge light should glow red for several seconds. Then plug in the charger, wait an hour, and see if the charge light is blinking. A blinking light indicates that the shaver electronics have sensed that the batteries have reached a full charge.

Reassembly:

1. Reassembly is the reverse of the disassembly procedure above, but with one additional procedure which must be done before installing the cutter frame: After reinstalling the shaver guts and before installing the cutter frame, make sure that the sideburn trimmer is retracted. Then orient the small spinning brass post on the end of the shaver guts such that the brass post is furthest away from the sideburn trimmer. If the cutter frame does not easily snap onto the shaver body or does not seat fully, then the orientation of this brass post is the problem.

There are several different battery chemistries, each containing different elements.

The common lead-acid battery used with engines contains lead, sulfur, oxygen, and hydrogen along with other elements used in making the case terminals and related components.

Lithium batteries can contain lithium, manganese, oxygen, chlorine, carbon and hydrogen. Other lithium batteries can contain lithium, iron, sulfur, carbon, and hydrogen. Numerous other combinations are also used in commercial lithium batteries

Other types of batteries include zinc oxide batteries, containing silver, zinc, oxygen and hydrogen
