How many types of batteries are there for the Digital Camera
Two kinds of batteries are widely available: Ni-CD (Nickel Cadmium) and Ni-MH (Nickel-Metal Hydride). There is a third type of rechargeable battery, Lithium Ion, that is becoming increasingly popular.The advantage of a Lithium Ion battery is that it offers better performance than the other two types. The disadvantage is that they do not come in the standard AA battery size, so you can't use them with most cameras.

10 mother tips for your laptop battery from www.my-batteries.net
When there are no power outlets in sight there's nothing more frustrating than a dying laptop battery. We've all been in that situation where we have a couple hours of work left to finish but our battery life is only estimated to last one more. Good news. Often times these situations can be avoided by optimizing the battery performance. Here are 20 tips that will help your laptop batteries last longer.
1. Calibrate your battery - Most laptop batteries these days have internal processors that provide an estimate of your battery life. Calibrating your battery so it shows the correct battery time and percentage is the first step in getting the most performance out of your laptop battery. Ideally, you should do this 3-4 times per year and should consult your owner's manual for instructions.
2. Adjust your settings - Just about every new laptop will have some kind of advanced power options settings. Optimize these settings for maximum performance.
3. Buy the Right Processor - The type of CPU can have a huge impact on how long your laptop will last on a full charge, Newer CPUs even shut down parts of the chip to conserve power. Intel chips tend to be more powerful than the AMD ones with their larger L2 cache but use more power, but you can get your work done faster so the total power used is about the same either way. The newest 65nm Memrons by Intel are extremely powerful and power efficient. Dual cores with 4MB cache and low power. The AMD Turion 64 line when they come out will compete with the Intel Memrons as they will have chips that are even more power efficient. The Pentium M chips use even less power but not as powerful since they are not dual core.
4. Only run programs you need - Having multiple programs running at the same time seems like an unnecessary way to drain your battery. Instead consider running only program at a time. In other words, if you're browsing the web don't leave your email client running in the background, check it when you're done surfing the web.
5. Dim your screen - One of the fastest ways you can kill your battery is by leaving your screen brightness high. Dim your screen to the lowest level you can possibly manage.

Exercise Your
Battery
To increase the life of your batteries, don’t leave them dormant for extended periods of time. Even if you use AC power most of the time, use the battery periodically to keep it fresh and healthy. Unplug your AC adapter when the phone, computer, etc. is not in use.
BatteryStorage
Store batteries in a cool, dry place away from heat and metal objects. Batteries left idle for extended periods of time will self-discharge. Just remember to charge them before use.
BatteryReplacement
If your battery used to last 8 hours and now only lasts 2 hours, it could be memory effort or just time for a new battery. NiCad batteries last approximately 700 charge/discharge cycles, or about one and a half years on average. However, NiMh batteries will normally last for only approximately 400 charge/discharge cycles.
Recycle Dead Batteries
Please be kind to the environment and not throw your batteries in the trash. The environmental protection agency (EPA) estimates that 200 tons of cadmium and 260,000 tonnes of lead enter the waste stream annually. Please send your old batteries to EarthVision for safe recycling (address to "Recycling Dept.) or use one of these organizations:

Break In New Batteries
New batteries come in an uncharged condition. To break in a new battery, we suggest charging and then discharging the battery 2 to 4 times so they can reach their full, rated capacity. You can discharge most batteries by unplugging the AC adapter and leaving them turned on until completely discharged. Some phones have a desktop charger/conditioner which will speed up the process.
Charging Your Battery
Never charge your battery for more than 14 hours. If you are using a Nickel-Metal Hydride (NiMh) or Lithium-Ion (Li-Ion) battery, your charging time should be less than 14 hours. Manufacturers’ manuals normally state not to charge a battery for more than 24 hours, but if you leave it on the charger for more than 14 hours you risk damaging the battery by overcharging.
Eliminate Memory Effects
Nickel-Cadmium (NiCad) batteries suffer from an affliction known as the memory effect. The battery will only charge to the level of which the battery was last discharged due to an accumulation of gas bubbles on the cell plates. If a battery is discharged to 30% and then recharged, the battery will only charge to 30% of its capacity and thus shrinking the battery’s "gas tank."
Burp Your Battery
The best way to eliminate memory and remove the accumulated gas bubbles on the cell plates is to "burp", or condition it. This means draining the battery until your portable phone shuts off, and then recharging it. Again, the desktop charger/conditioner will speed up this process

MP3 Player Shopping Tips
Choosing the right MP3 player isn't that difficult, but one player does not fit all. People will want different things from their players.
Think about how you'll use the player. Joggers will almost certainly want a lightweight, flash-memory-based device, since hard drives don't react well to the shock of bouncing around all the time; audio aficionados who want lots of music at their fingertips should keep their eyes on the highest-capacity hard-drive models. And if you want to view video or photos on the device, the quality of the screen is an even more critical consideration.
Try your favorite before taking it home. We can't stress this enough. Make sure you can use the on-screen display to navigate to a specific song, and ask a clerk to show you how to transfer music to the device, if possible. Always bring your own set of headphones to listen to the sound quality of each unit you're interested in.
Get the largest-capacity device you can afford. Whether you buy a flash- or hard drive-based MP3 player, make sure to choose a model with the largest storage capacity possible. Even if you don't think you'll need it now, you will probably be happy to have it later.
Pay close attention to the user interface. Does the player's menu system make sense to you, and is the interface easy to use? If you can't find the songs, artists, or albums you want to play quickly and easily, keep looking.
Mind your power options. While some flash-based portable players use replaceable alkaline batteries, most hard drive-based units feature a built-in rechargeable battery that cannot be easily removed. While these devices can keep going for tens of hours, if you're not going to be somewhere near a power outlet or a computer with a USB port, you might find yourself out of juice with no way to charge the player.
Look for wide file format support. All players should support the MP3 format; but if you prefer WMA, AAC, or Ogg Vorbis, make sure your player of choice can handle the files.
Consider a player with an FM tuner. Usually found on flash-based players, this feature isn't essential, but it's nice to be able to listen to the radio--especially if you grow tired of your recorded music.
Do you need a carrying case? Some players come with a small carrying case, others don't. The more expensive and more fragile the player (hard-drive devices are the most delicate), the more likely you'll want a custom-fitted case to protect it. Even if the drive mechanism isn't delicate, you should take into account how upset you would be if your new possession were to get scratched.
Shop around, online and offline. MP3 players are widely available in almost every consumer electronics outlet, and their prices fluctuate. You can check prices from a variety of sources before you buy.

Notebook batteries Society
Next notebook computers introduced nickel hydrogen (NlMH) batteries, such batteries have better Xingjiabi and greater power, and "nickel-hydrogen batteries is one of the most environmentally friendly batteries, and pay attention to environmental countries strongly advocated the use of nickel-hydrogen batteries, which are recovered reuse, and the destruction of the environment is also the smallest. But nickel-hydrogen batteries and lithium electricity compared still some shortcomings. charging time, a heavier weight, capacity than lithium -- small, battery discharge time is too short continuing, and memory effects, although unlike its memory nickel cadmium batteries so big, but still need to discharge, the user must be exhausted before charging. Nickel-hydrogen batteries will be lithium-ion (Li-ion) cell replacement. Lithium power long ago have started to use it, not security, often there will be in charge of burning, burst, it might be too active because lithium elements reasons. Later there will be a version of the lithium-ion batteries and joined the active ingredients can contain lithium elements, so that the real power lithium reached safety, efficiency, convenience, and the consequent elimination of the old lithium. They are also very simple distinction, from the logo, we can identify the cells, lithium call for Li, lithium-ion batteries for Li-ion. Now, notebook use of the so-called lithium call actually lithium-ion batteries. Lithium ion battery Chuneng density, may at any time charging and continuous discharge time, the general in about three hours. Battery capacity from the size of the main shows mAh (milliampere hours) to judge the value, such as 3000mAh, 4000mAh, the greater the value, the greater battery capacity
