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

Well you really cant just make sure that your acid doesnt all dry out inside of a battery if it all doesn then battery wont hold charge and if you top it off after its already dry it will have weak charge because it have done it too late, make sure to top off battery acid fluid when it doesnt touch the dips in plastic covers. Batterys will go bad no matter what i have a f550 here in a shop and had to chage out 2 of them because they were over 6 years old and even though fluid is topped off it still doesnt hold charge.

Check all your fluid levels every 1st and 15th of a month. Best way to keep your car in good shape.

Might last a little less, but being 2mm thicker may provide better contact, and since it is a bit smaller, if the battery socket is just a slide in clamp, yes you can interchanged them. Not so from a 2430 to a 2032, that one is a no no.

the best way is to replace with a known good battery also a voltmeter - read battery under load - it should be near 9 volts

Electrolyte acts as a good conductor in liquid state. It makes the cations and anions to move towards cathode and anode respectively thus conductiog current.

Who invented the potato battery? Alessandro Volta.lol maybe that's why it's maybe called volts

It really depends on what you do on the iPod. Most times, the battery can last for 2 hours if you are playing a game,1hour if you are playig a 3D game and other different times depending on what you're doing

The function of a battery snap is to stop the current from the battery from flowing whenever you want to, and so that its safer.

Around 1800 Count Alessandro Volta invented a wet battery called a Voltaic Pile and later John Frederic Daniell invented the Daniell Cell in 1836, which was a big improvement in the battery.

So the original term for the battery was a Volatic Pile.

Walmart for one, but try this interstate website locator tool http://www.interstatebatteries.com/content.aspx?dsNav=Ntk~SearchGroup|InterstateAllBatteryCenter|3|,N~2147384905,A~Part+Number&searchTerm=InterstateAllBatteryCenter

You can remove the batteries and test their voltages individually. Looking at the weakest one, 1.50 or more volts is good and will have a long life. 1.0 volts or less is almost dead. Sometimes you can tell the battery is weak by the contrast on the screen, but that's a matter of experience with that calculator.

The function of a bios battery is basically to reset your bios if something goes wrong and you corrupt it. Bios batteries usually contain a little bit of information on them. Therefore, when you remove a bios battery, it goes back to default settings.

**Note**

removing a bios battery is usually a last resort to reset your bios. There are several other ways to reset your bios such as a jumper cable or (included in some never motherboards,) a reset bios switch.

Smoke alarm batteries are easy to replace, once you find where they go. The design varies from brand to brand.

Usually, the battery is located on the side of the alarm, either in a "drawer" or a swinging compartment. There may be a small plastic latch holding it closed. Occasionally, it is necessary to remove the alarm from the wall or ceiling to find the battery compartment. This can be done by rotating the entire alarm counter-clockwise until it releases. The battery compartment is designed not to close if the battery is inserted incorrectly.

Many smoke alarms have an option to permanently screw the battery compartment closed. This is typically done in rental units to prevent tenants from removing the battery during a false alarm. In this case, the landlord is required by law to change the battery. If you are the landlord, consult the alarm documentation (which can be found online) for instructions on how to remove the locking screw.

If by bounce you mean like a rubber ball bounces:

The bounce, or not is determined by the mechanical properties of the battery, and these doesn't change with the battery being charged or not.

Dead, or fully charged, a battery will behave just the same when dropped.

Well the flat of the battery is the negative side.
