Your iPod uses a lithium ion battery. That is not the round kind found in a flashlight. Rather, it is a light, thin battery that is more powerful than conventional batteries. Using your device causes the battery to drain – simple enough. However, every time you charge your iPod battery, it loses some of its total charge. Over time, it will simply run out of power and you will have to replace the iPod battery with an iPod battery replacement kit.

You are walking along, listening to your favorite tunes when your iPod shuts down. You go home to charge it up, and after a few hours, you are ready to go. You pop in your headphones, turn it on and nothing. Your iPod battery has died.

Now before you shake your fist in anger or frustration, it is good to understand why your iPod mini battery has kicked the bucket. It might not be of much consolation now, but knowing how iPod batteries work is always useful information to have.

Let us say that an iPod mini battery holds enough power to play for one hour. After an hour, it dies out, so you charge it again. It is now full, but instead of an hour, it only plays 59 minutes. Over time and repeated charges, the battery simply cannot hold a charge any more. Once that happens, it is time to change the iPod battery.

Now, you may be asking yourself why your iPod does not use conventional batteries. Here is the answer: find any size battery in your home and try to place it in your iPod. You will soon figure out why lithium ion is the weapon of choice for iPod mini batteries. They are smaller, longer lasting, and have the juice to power today’s high-performance devices.

When an iPod battery dies, you can easily purchase an iPod mini battery replacement kit, instead of purchasing an entirely new unit. According to Apple, iPods are designed to last for years to come.

Therefore, the key to long iPod battery life is to only charge it when you have to. And remember, dead iPod batteries are those that won’t hold any charge at all. An iPod battery with some charge left can hold some charge can still be useful, but you will still want to consider purchasing an iPod replacement kit.

Also keep in mind that when your iPod mini battery does die, it requires a proper funeral inside a proper container. No, you don’t need to buy a casket and a plot, but you do need to adhere to local laws when it comes to battery disposal.

You may have a good reliable vacuum for cleaning most of your home, including your carpets, wood flooring or vinyl floors. There are very many good electric vacuums to choose from. But sometimes, it is a good idea to have a cordless vacuum to clean certain hard to reach areas, or your auto, or just for quick cleanups when you don’t want to drag the big vacuum out.

You will find that a good cordless vacuum will come in handy for many situations, and they are available at very reasonable prices, especially if you can look for them on sale. There are many brands and styles to choose from so you can choose the one you like that meets your budget. Just about any department store, appliance store or home improvement center will carry a wide variety.

One of the best and most common uses for a cordless vacuum is to reach hard to reach areas. Sometimes you cannot reach a ledge or top of a piece of furniture, or perhaps you want to vacuum the blades on the ceiling fan and you cannnot use your big electric vacuum, but you can lift the cordless job up to where you can get the job done. This light weight peice of equipment can do a lot of jobs like this for you.

Cordless vacuums run on battery power. You don’t have to change batteries, however, most of them come with a battery charger; you plug the charger into the wall when you are not using the vacuum so it is charged up when you are ready to use it. They usually can be used for up to two hours without an additional charge.

Another common use for a cordless vacuum is to clean out cars and trucks. With the car in the driveway or at the curb, you may not be able to reach it with electricity, so a cordless is ideal. Most cordless vacuums come with attachments that are small enough to reach into tight spots in vehicles.

I bought a multimeter from Radio Shack awhile back without paying close enough attention to its capabilities. By the time I got around to testing it, it was too late to take it back — but apparently there's no way to make it sensitive enough because a fresh battery barely moves the needle.

Santa brought me a simpler battery tester but it tells me a battery is full strength when its near the end of its life (e.g., digital camera says its dead and a flashlight is fairly dim).

So, I've hit both ends of the sensitivity spectrum without getting what I need! I just want to be able to test my rechargeable batteries to see when they're charged, weak, or problematic and needing to be replaced.

Do you have a Batteries Plus Store near where you live?

They have a some battery tester online like this one:

The great thing about Batteries Plus is that, if you go there with your equipment, they have a tech center and will be able to figure out why the devices you bought are giving faulty information.

They've always test my battery equipments free of charge. Give them a shot .

I thought that you need a physical contact between the charger and the battery so the electricity actually arrives inside the battery.
Now my new electrical toothbrush seems to work differently. It has a battery, the manual confirms. It also has a charger. But all I need to do is to put the toothbrush on the charger.

How does that work? Both parts are plastic covered.
Yes, a Sonicare product.

Its using induction charge principle. Essentially the primary coil side of the transformer is built into the base and the secondary coil is built into the toothbrush.

The primary winding of the inductive charger transmits charging power to the secondary winding, inside the target device, without making direct electrical or mechanical contact with it. In the target device, power is received with a coil and then rectified by a diode. This DC voltage is used in charging the battery of the device.

I tried jumpstarting my car battery with a booster battery. I think my booster battery is getting old. I do have 2 booster batteries available. Neither of them work stand alone.

You are risking an explosion. Make sure that the starter is not the problem. By connecting three batteries together you have the potential to damage your car permanently. One good battery should work to jump your car. Remove the battery in the car and put a known good one in. If the car still will not turn over, you have a starter or other problem.

When you own a battery powered lawn mower, you will want to pay close attention to the lawn mower batteries you purchase. Therefore, the first thing you will need to do is understand about all the different types of lawnmower batteries that are available and which ones you should be buying.

There are two general types of lawnmower batteries available for lawn mowers, these are the nickel cadmium and the lead acid batteries. Each have their advantages, however, many people are turning to nickel cadmium batteries because they are environmentally friendly and provide for better performance. All lawnmower batteries are rechargeable, however, they do not have unlimited life, they will have to be replaced occasionally. If you find that the mower is running strangely, or have troubles starting it up, it may be time to replace look for lawnmower batteries. There are two different types of batteries used in a lawn mower, 12-volt, and 6-volt. To find which type of battery you need for your lawnmower, the best thing to do is refer to your owners manual.

When it comes to lawnmower batteries, some of the most popular brands are snapper and Toro. Because battery powered lawnmowers comes in several styles such as push behind and riding lawnmowers, it is essential that you understand which batteries work well with your specific lawnmower. People choose battery powered lawnmower for a variety of different reasons. One such reason is the money saved when compared to the cost of gas-powered lawnmowers. With a battery, you can recharge it and get many uses out of it. With a gas-powered lawnmower, you have to constantly purchase gasoline to mow your yard and if you have a large yard, that could prove to be a costly task. Another reason for the popularity of a battery powered lawnmower, is that they are typically quieter and much more economical. Of course, as with anything, there are some disadvantages, such as the battery running dead before you are finished, or the amount of lawn it can mow with one charge.

What is great about lawnmower batteries is that you can find them almost anywhere, such as outlet stores, department stores, specialty stores, or even various places online. When looking online for a lawnmower battery, make sure that you only buy the battery from a reputable company.

Talk to your friends and family to determine where they buy their batteries from and who they would recommend. Make sure the battery comes with some form of warranty to protect you from a bad investment and that the dealer knows what they are talking about when making recommendations.

Your car’s electrical system runs because of several essential
components including: a battery, fuses, and an alternator. When
any one of these components fail, your car won’t run or it will
perform poorly. Unfortunately, it isn’t always apparent which
part is giving you the trouble. We’ll examine each component,
discuss its unique characteristics, and outline simple
maintenance options to help you make the proper diagnosis.

1. Alternators. Car
alternator problems are usually noticed when you realize
the juice to your headlights has been reduced. No longer can you
see hundreds of feet in front of you, instead the light barely
makes it past the front bumper. Check the wires leading to the
alternator and make sure that they are secure and free of
corrosion. Examine your alternator belt for cracks as well as
for tension. If your headlights are still dim, then it is likely
your alternator will have to be replaced. Don’t put it off as
the alternator can drain your battery.

2. Batteries. If your car won’t start, your battery may
be to blame. Most cars come equipped with sealed, maintenance
free batteries. Still, “maintenance free” isn’t an entirely
correct designation as corrosion can build up on the terminals
causing an otherwise fine working battery to fail. Remove the
cables, clean with a wire brush, and reattach the cables. Apply
lubricant to each terminal to limit future corrosion. If your
car’s battery is not “maintenance free” add distilled water to
each cell as needed. Use a good set of jumper cables to get your
car started. If the car still won’t start the battery is either
completely shot or the starter or solenoid [relay] are not
working. Battery life varies depending on what type of battery
is in your car and usage; consider replacing your battery every
3-5 years before problems arise.

3. Fuses. Your dash lights may be working, while your
left rear blinker has failed. If that is the case, it is likely
your electrical problems are with the fuses. You can pull off
the fuse panel [usually located under the dashboard] and check
to see which fuse has burned out. Today’s cars use transparent
blade style fuses that are rectangular in shape. Observe each
fuse and see if the internal wire has burned out. You can find
the fuse fast if the auto manufacturer has labeled each one by
circuit. If not, you will have to determine by a process of
elimination which fuse has failed and replace it.

Batteries and fuses are widely available at auto supply stores
and most will carry a selection of alternators too. If you find
prices for your Ford
alternator or BMW
alternator are too high, you can save plenty of money on
original equipment manufactured parts with some of the reputable
online providers. Shop with those retailers who have the widest
selection of inventory, the best prices, and the most favorable
shipping and return policies.

Like other portable consumer electronic devices digital cameras use batteries as their power source. All batteries have one major drawback: they only last for a limited time. In this article we will explain what camera features consume the most energy and how you can squeeze more life time out of your digital camera battery.

There are many types of battery. Your digital camera might be using disposable batteries or maybe it uses rechargeable ones. Rechargeable batteries use a variety of technologies such as nickel cadmium, lithium ion or lithium polymer. Battery technology has advanced in the last years but batteries life time is still considerably short. It is very frustrating to come across a great photo opportunity just to find out that you have run out of batteries.

When it comes to power consumption not all digital camera features are equal. Some of the digital camera greatest features are high energy consumers. By knowing which features consume the most energy you will be able to avoid or minimize using those features save energy and get more life time from your batteries.

The biggest energy consumers in a digital camera are the LCD screen and the motors that move the mechanical components of the camera such as the lenses when focusing or zooming. Digital cameras allow viewing of photos that were just taken on a small LCD screen. Some of them also allow shooting photos using the LCD instead of the traditional viewfinder. An LCD screen consumes relatively a lot of energy. This is the reason why all digital cameras turn off the LCD after a certain amount of time of no usage.

The other big energy consumers are the motors. Digital cameras have motors the move the lenses either to change the zoom or to focus. Motors consume relatively a lot of energy when moving the digital camera optical components. And finally the flash is a big energy consumer too. Shooting photos using the flash consumes more energy that shooting photos without flash.

So what can you do in order to minimize power consumption and get more life time from your batteries?

In conclusion until battery technologies improve to the extent that battery life is so long that it practically lasts forever you will have to be conscious about how you use your digital camera in respect to power consumption. Following a few simple guidelines can significantly improve power consumption and make your batteries last longer.

Disasters can strike at anytime and it’s important to always be prepared. Severe weather conditions like hurricanes can cause loss of power, but those are not the only things you have to watch out for. A power outage can occur during a heavy thunderstorm or a blizzard. Use the following tips to make sure you’re ready in case of emergencies.

Batteries are the most important to have, since they provide the power necessary to keep us going until the lights come back on. Be sure to keep a large supply of batteries of every type. Sometimes, the power can come back on in a short time, but there’s always the possibility that it could take hours or even days. Make periodic checks of dates on the batteries, so you will always have a fresh supply. It’s also good to have a lot so you can share them with neighbors who might not have any.

Radios

A battery operated radio can keep you notified of important updates, where you can go for help and if it’s safe to leave the home. They also provide comfort in knowing that you are not alone in the situation. Make sure you have the proper sized batteries to keep it running.

Flashlights

When the lights go out, one of the first things we reach for is a flashlight. Since there is no way to predict how long you will be without lights, having extra batteries will make sure that you won’t be left in the dark. You can also get battery operated lamps to put in rooms. You don’t have to hold them and they turn on with the push of a button.

Water Purifiers

Having a fresh supply of water during an emergency is extremely important. Boiling water will purify it but if the electricity is out, this might not be an option. Having a battery powered purifier means that you will always have a drinkable supply of water for you and your family.

Fans and Heaters

Since the power can go out at anytime, keep battery powered fans and heaters in your supply kit. This way you can stay cool in the summer and warm in the winter

Medical Equipment

Losing the electricity can be particularly frightening for people who rely on medical equipment that require electricity to work. A lot of this equipment has battery back ups, so make sure you have a good supply of the required batteries on hand.

Centralized Supply Location

Have a centralized location for your supplies. Dedicate a whole area just for batteries and keep them in size order. This way if the lights go out, you won’t have to stumble around in the dark trying to find your supplies. They’ll all be in one place, so you can easily get your hands on them.

By following these tips you will find it much easier to endure the aftermath of emergencies while you wait for power to be restored.

I want to buy a battery tester but, they all say they test 1.5v AA & AAA batteries. Rechargeable Nimh’s are 1.2v. and that’s mostly what I want it for. This is the tester I am looking at. We don’t have any department stores in town so I am stuck with paying Radio Shack prices.

Much Obliged!

Buy a volt meter. They are more accurate and can be used for other purposes. Overall, your best buy.
