I want to have it in series. Code as follow:

1. When use laptop battery, pls recharge after battery exhaust. Charging the battery up full one time. Don't charge or discharge it halfway. Do make the battery is in best case.

2. Take out battery from the laptop, if the computer won't be used for a long time (over two weeks).

3. Make sure battery is far away some easy electroconductive material(as water or metal product), which avoid the laptop battery short circuit and unavailable.

4. Make sure don't place the laptop battery alone over six months without charging.

I like to see very much

what Lithium Ion ?

Lithium Ion: Lithium-Ion (Li-Ion) has become the new standard for portable power in consumer devices. Li-Ion batterys produce the same energy as NiMH battery but weighs approximately 20%-35% less. This makes a noticeable difference in devices such as cellular phones, camcorders or laptop computers where the battery makes up a significant portion of the total weight. Another reason Li-Ion batteries have become so popular is that they do not suffer from the "memory effect" at all. They are also environmentally friendly because they don't contain toxic materials such as Cadmium

How can I maximize the performance of my battery?

There are several steps you can take to help you get maximum performance from your battery:

1. Prevent the Memory Effect - Keep the battery healthy by fully charging and then fully discharging it at least once every two to three weeks. Exceptions to the rule are Li-Ion batteries which do not suffer from the memory effect.

2. Keep the Batteries Clean - It's a good idea to clean dirty battery contacts with a cotton swab and alcohol. This helps maintain a good connection between the battery and the portable device.

3. Exercise the Battery - Do not leave the battery dormant for long periods of time. If a battery has not been used for a long period of time, perform the new battery break in procedure described above. 4. Battery Storage - If you don't plan on using the battery for a month or more, store it in a clean, dry, cool place away from heat and metal objects. NiCad, NiMH and Li-Ion batteries will self-discharge during storage; remember to recharge the batteries before use.

The Do's and Don'ts of Battery Use

Battery Do's:· Fully charge/discharge battery up to 4 cycles before achieving full capacity of a new battery. · Fully discharge and then fully charge the battery every two to three weeks for battery conditions.· Run the device under the battery's power until it shuts down or until you get a low battery warning. Then recharge the battery as instructed in the user's manual.· Remove from the device and stored in a cool, dry, clean place if the battery will not be in use for a month or longer. Recharge the battery after a storage period.· Ensure maximum performance of the battery by optimizing the device's power management features. Refer to the manual for further instructions.

Battery Don'ts:· Do not short-circuit. A short-circuit may cause severe damage to the battery. · Do not drop, hit or otherwise abuse the battery as this may result in the exposure of the cell contents, which are corrosive.· Do not expose the battery to moisture or rain. · Keep battery away from fire or other sources of extreme heat. Do not incinerate. Exposure of battery to extreme heat may result in an explosion.

Should I Recycle the old battery?

Yes. Do not throw these batteries in the trash. For recycling nearest you, please call 1-800-822-8837 or visit www.rbrc.org. Please be kind to the environment and Recycle.

Laptop Battery Life

1. Exercise the battery monthly. They stagnate if not used regularly. Battery University states the exercise is needed after every 30 charges (cycles). Apple is likely trying to simplify so I go with the 30 (partial) cycles as I don't use it as frequently.

2. If not to be used in the near future, discharge it to 40 - 66% and store in refrigerator (NOT FREEZER; keep above 0°C/32°F). I keep my extra battery there and warm it then charge it for flights.

3. Never allow to fully discharge and leave at that state. This is what likely killed the camcorder battery for Herman. Canon (mine is a ZR50) states to remove the battery from the camcorder when not in use as it will discharge it even if in off position.

4. Avoid leaving it plugged into the charger for prolonged periods such as sitting at a desk for weeks. Though I believe it's the least problematic, Li-ion batteries don't like being at a fully charged state for long periods either. As Herman said, it's best to use them or they will crystallize and lose life.

5 Step: Laptop Upgrades You Can Do Yourself

Your notebook may be old, but that doesn't mean its days are numbered. We'll show you how to breathe new life into your portable by opening the hood and upgrading some basic components.

Want better performance from your laptop? The conventional wisdom has long held that you should simply buy a new one. You can put such conventional wisdom aside: Upgrading a laptop may not be for the timid or the impatient, but if you're handy with a screwdriver, and the sight of a circuit board doesn't scare you, an upgrade can be a far more affordable solution.

We took tools to hand and worked our way through eight common (and not so common) laptop upgrades, in some instances stripping our test machines--a Dell Inspiron E1505 and a Dell Inspiron 6000--down to the bare chassis. We can't fit complete step-by-step, unscrew-this-and-unplug-that instructions for everything into this article, but we can provide tips to help with each process.

And note that every laptop varies: Even machines from the same vendor can have very different designs and therefore wildly different disassembly methods.

Before you start, keep these essential points in mind:

* Many of these upgrades will void your laptop's warranty.* Some upgrades can damage your laptop. If you are at all uncomfortable with such tinkering, leave it to a pro.

* Most vendors provide disassembly instructions in their products' service manuals, which can usually be found on their Web sites' support sections.

* Unplug your laptop and remove the battery before attempting any upgrade. Also, to avoid damage from static electricity, use a grounded wrist strap.

* You'll need a collection of small screwdrivers, including flathead, Phillips, and possibly even Torx.

* Speaking of screws, keep them organized as you remove them. We like to use Dixie cups for each step. Just write "LCD assembly" or "keyboard" or whatever on each cup as you go, to help you remember which screws go where.

* Pay special attention to wiring. Laptops have intricate channels where the wiring must run; stray wiring may get pinched or may prevent other parts from fitting together correctly.

* No matter what machine you're working on, first upgrade your BIOS. You'll need up-to-date BIOS code to support many newer components.

* Not every laptop component can be upgraded. Some may be soldered or otherwise permanently attached
