What is the difference between Ni-Cd, Ni-MH and Li-ion batteries?

Batteries in portable consumer devices such as a laptop, camcorder, cellular phone, etc., are typically made using either Nickel Cadmium (Ni-Cd), Nickel Metal Hydride (Ni-MH) or Lithium Ion (Li-ion) battery cell chemistry. Each type of rechargeable battery chemistry has its own unique characteristics:

Ni-Cd and Ni-MH:

The main difference between the two is that Ni-MH battery (the newer technology of the two) offers higher energy density than Ni-Cd. In other words, the capacity of a Ni-MH is approximately twice the capacity of its Ni-Cd counterpart. What this means is for you is increased run-time from the battery with no additional bulk or weight. Ni-MH also offers another major advantage: Ni-Cd batteries tend to suffer from what is called the "memory effect". Ni-MH batteries are less prone to develop this problem and thus require less maintenance and conditioning. Ni-MH batteries are also environmentally friendlier than Ni-Cd batteries since they do not contain heavy metals (which present serious landfill problems). Note: Not all devices can accept both Ni-Cd or Ni-MH batteries.

Li-ion

Li-ion has become the new standard for portable power in consumer devices. Li-ion batteries produce the same energy as Ni-MH battery but weighs approximately 20%-35% less. This is can make a noticeable difference in devices such as cellular phones, camcorders or notebook 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 or Mercury.

Is it Possible to Upgrade the Device's Battery to a newer Chemistry?

Maybe. Ni-Cd, Ni-MH and Li-ion are all fundamentally different from one another and cannot be substituted unless the device has been pre-configured from the factory to accept more than one type of battery chemistry.

Please refer to your manual to find out which rechargeable battery types the particular device supports or use our Battery Quick Finder Wizard to find all the compatible battery for your device. It will automatically list all of the battery types supported by the your specific device.

My new battery isn't charging. Is it defective?

Usually NO. New batteries come in a discharged condition and must be fully charged before use. It is recommended that you fully charge and discharge the new battery two to four times to allow it to reach its maximum rated capacity

It is generally recommend an overnight charge (approximately twelve hours). It is normal for a battery to become warm to the touch during charging and discharging.

When charging the battery for the first time, the device may indicate that charging is complete after just 10 or 15 minutes. This is a normal with rechargeable batteries. New batteries are hard for the device to charge; they have never been fully charged and not brokenin. Sometimes the device's charger will stop charging a new battery before it is fully charged. If this happens, remove the battery from the device and then reinsert it. The charge cycle should begin again. This may happen several times during the first battery charge. Don't worry; it's perfectly normal.

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:

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.

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.

Exercise the Battery - Do not leave the battery dormant for long periods of time. We recommend using the battery at least once every two to three weeks. If a battery has not been used for a long period of time, perform the new battery break in procedure described above.

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. Ni-Cd, Ni-MH and Li--on batteries will self-discharge during storage; remember to recharge the batteries before use.

Sealed Lead Acid - (SLA) batteries must be kept at full charge during storage. This is usually achieved by using special trickle chargers. If you do not have a trickle charger, do not attempt to store SLA batteries for more than three months.

What is a "smart" and "dumb" Battery?

Smart batteries have internal circuit boards with smart chips which allow them to communicate with the notebook and monitor battery performance, output voltage and temperature. Smart batteries will generally run 15% longer due to their increased efficiency and also give the computer much more accurate "fuel gauge" capabilities to determine how much battery running time is left before the next recharge is required.

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.

How to prevent the battery memory effect?

Is very simple, only the use of mobile phones at the time of each battery completely used up on the list. This will greatly extend the battery life.

when the battery memory effect occurs when you can try this approach?

wrap the battery with a newspaper before being placed in plastic bags, wrapping well into the freezer for three days (newspapers can absorb excess moisture).

Three days later, two days out at room temperature decentralization.

two days after charging the battery, charge mobile phone saturation, yellow wrap test (estimated to save80%-90%).

the battery is not charging the common-sense reasons and solutions?

Charger and the battery connection is not correct, be properly connected;

Charger or the battery contacts are not clean, need to clean, dry;

Battery has aged, and need a new battery.

the battery power faster than normal, common-sense reasons and solutions?

(1) Bad cell phone coverage in weak signal areas, so that power consumption accelerated in the normal coverage area does not experience this problem.

(2) Mobile phone antennas in use is not stretched, so that power consumption to accelerate in the use of mobile phones to form the habit of pulling the antenna could be saving.

(3) A new battery or long-term do not use the battery in use after the first three can be had to the normal standards of performance.

(4) The old batteries, or battery memory effect occurs battery depletion of a very short time, when the battery needs to be replaced.

(5) Batteries when used in extreme temperatures, high or low temperatures can significantly affect battery performance, the need for frequent battery recharging.

the battery maintenance of a few common sense?

(1) In order to extend battery life, the charging time of no more than the necessary charge period (5To7Hours); but the first three to use a new battery must be discharged to the phone automatically shut down after the recharge8-12Hours! This ensures that the battery capacity is sufficient to stimulate them;

(2) Only when the manufacturer first wife with the purchase of the charger;

(3) Battery contact with metal or non-contact with grease fittings, pay attention to moisture;

(4) Battery Do not immerse in water or thrown into the fire;

(5) Batteries, such as the refrigerator, not on the low-temperature, high temperature, such as near the stove;

(6) Handling the battery, use of special facilities;

(7) For changing batteries, use only approved mobile phone battery type;

(8) For a memory effect of battery, each battery should be used up, rechargeable, or the battery memory effect occurs, greatly reducing battery life.

(9) Battery life is normally calculated by the number of charge-discharge and, therefore, adequate electricity, run out of electricity, to maximize battery life.

How to maintain your laptop battery?

1, the majority of notebook computers need to be fully charged for eight hours, but in general in the first four hours, they can charge a good 75% of the electricity, while the remaining 25% will take more time.

2, the new battery before charging the battery in power must take place finish, and then charge, charge off the best course of charge, until the power indicator light green or off. After a few full charge and discharge the battery in order to achieve the best results.

3, there is a dedicated power management software must be installed on the laptop, the system can be preset settings let you get a good battery life results. Not have a dedicated power management notebook, be sure to take advantage of the system built-in power management projects.

4, the battery will automatically discharge when not in use, in storage when the need for its adequate electricity. If you do not have a long battery every few months, we must fully discharge and charge.

5, without rendering the battery short-circuit or the use of metal packaging, pay attention to moisture, moisture.
