Good to know!
Factory or after produced batteries...
The manufacturers of a device - do not produce batteries with one-two exceptions (such as Sony, Panasonic, and Toshiba).
The batteries made for orders in battery factories. Usually the only differences between the factory and after produced
batteries are that they are made in different shifts and different stickers, packaging, identities are given to them.
So as the battery factories don't produce notebooks, tool- machines, PDAs, cameras as these manufacturers don't produce batteries.
Which battery is still considered as factory battery, those are available from the formal distributor of the devices and services in factory packaging and with guarantees!!!
1. What is the battery?
Battery can be all kind of equipment, which stores energy for later use. The word battery is used for an electrochemical device, which comprising the chemical energy with the help of a galvanic cell into electricity. A galvanic cell is a very simple structure, consisting of two electrodes (anode and cathode) and an electrolyte solution. The batteries consist of one or more voltaic cells.
The battery is an electricity storage device. The battery does not produce electricity, but stores it. As the chemicals exchanged in the battery, the electricity is stored or released.
In case of rechargeable batteries, this process can be repeated many times. The batteries are not 100% efficient - some energy is lost as heat and chemical reactions occur during charging and discharge. If we use a 1000 watt from the battery, then up to 1200 watts or more is needed to fully charge. The slower rate of charging and discharge is more effective. After a 6-hour charge a 180 Ah battery can be charged up to 220 Ah after 20 hours of charging and can reach 260 Ampere-hours after 48 hours of charging. Usually the efficiency of a graphite-acid battery is 85-95%, the alkaline and Ni-Cd battery approx. 65%.
2. How do I recognize my battery?
The first information you need, the manufacturer and model of the equipment, which will require the battery. E.g.: Toshiba Satellite Pro 400, or Compaq Presario 1283. There is usually a label on the battery and a part of the contained information will help for the sales to identify quickly the necessary battery.
This information includes the battery voltage (note: this is not the same as the power supply voltage), the capacity and the chemical structure of the battery. E.g.: Li-ion, Ni-MH or Ni-Cd. This information is necessary in order to be sure that the provided information is equivalent to what we know about your battery. On many batteries there are numbers on the label, sometimes this help us to identify the battery. We suggest writing down all these information or making sure you have it before calling us. So, we can serve you better.
3.What is the difference between Ni-Cd, Ni-MH and the Li-ion?
Li-ion (lithium.ion). This is the newest type of battery.
However, this is the easiest battery, which is currently available, and it also provides more power than other battery types. We don't know of any memory effect, and can handle the simplest way of this type.
The disadvantage of this, that it has the highest cost of development, so the price is usually considerably higher than the other battery type.
Ni-MH (nickel metallic hydrogen). This model is currently the most commonly used incase of laptops (although Li-ion fast become a top rated.) This type of battery relatively low cost of production, thus generally cheaper than Li-ion. This battery type is prone to memory effect, so it is important to properly manage the Ni-MH battery pack, if you want to achieve the best use of time.
Ni-Cd (Nickel cadmium). It is the oldest type of battery, and usually can be found in older laptops. The main advantage of this type of battery is, that it has also a bigger load, so more portable to electronic tools, or used for equipment which require a lot of energy to operate effectively.
Known to suffer the memory effect. It is therefore very important for the proper use of this type, if we want to make sure the most efficient use.
4. How long will supply power the new battery?
Difficult to determine the battery usage time for a laptop. The actual operating time depends on electricity demands of the equipment. The screen, the hard driver and other accessories may mean additional stress to the battery, significantly reducing the operating time.
The total battery usage time, however, still depends on the implementation of the equipment. Disadvantage of this type of battery that usually a new high-performance battery will continue to operate the equipment with 30 - 50% than the old item was, when it was new.
5. How do I maximize battery performance?
Recommended to condition it several times (fully charge and discharge) the new battery to reach its maximum capacity.
The Ni-MH and Ni-Cd batteries should be conditioned at least once a month. This will reduce the memory effect.
Use the battery at least once a month, even if kept in dry and cool place. Clean the metal connector (which connects to a laptop - usually color gold or silver) with alcohol or other degreaser made for electronic equipment. This ensures better conductivity, which helps the flow of energy from the battery into the Notebook.
Fully optimize the power supply characteristics in the system BIOS and in the operating system, this also improve the battery's performance. Check the instructions that are fully aware of using these settings.
6. How long does the battery last?
Under normal circumstances, a notebook battery life is approx. 1.5 to 3 years. As the rechargeable battery is approaching the end of life, the user will perceive a reduction in the use of time.
7. How to connect batteries?
Warning! When we connect accumulators (batteries) each battery's ampere and voltage rating should be the same! The batteries can be connected in series. The first battery's a positive ending is connected to the second battery's negative ending and the second positive endings connected to the negative ends of the third, and so on. The connected battery's voltage will be the amount of each battery's voltage. Binding of the battery: positive to negative, than this to positive, than this is to negative, and so on. The battery power is unchanged.
The batteries can be connected in parallel. The first battery's positive ending connecting to the second battery's positive ending, the positive ending of the second battery is connected to the third battery's positive ending, the first battery's negative terminal connected to the second battery's negative terminal the second battery's negative terminal is connected to the negative ends of the third negative ending, and so on, while the voltage is unchanged.
For example, 5 x 6V 10AH batteries connected in series resulting a row of battery line, which is 30 voltage and 10 Ah. If we connect these elements in parallel we get a battery line which is 6 Volts and 50 Ah. Usually the power-storage batteries are similarly implemented. Six two-volt cells connected in series gives a 12-volt battery. Many Ni-Cd batteries are arranged similarly.
8. The battery's status, characteristics
Volt: the new battery's voltage must always be the same as the original battery voltage.
MAh: this is the scale of milli-Ah (1 mAh = 0,001 Ah). High rating of Ah means a longer period of use and do not cause conflict.
9. How to charge batteries?
Our Ni-MH chargers are completely automatic.
Connect the charger into a DC outlet (or to an AC switch outlet in case of MH-C204F-CD only) and insert the batteries in the charger corresponding pairs or fours to start charging. Red light indicates that charging is taking place. The light turns green when charging is complete, and then the charger automatically switches to trickle charging. The trickle (leaking??) charging keep the batteries ready to use, fully charged. Read the charging guide about detailed instructions of different varieties of chargers regarding the operation.
10. What is the "memory effect"?
The memory effect is mostly occurs at Ni-Cd, and less Ni-MH batteries. This means that if a battery repeatedly is only partially consumed before uploading, then the battery "forgets" to go further and can be exhausted of its total capacity. To illustrate: If you regularly upload the battery completely, but then use only 50% of it before recharging, then eventually the battery will not be aware of the additional 50% capacity, which will thus remain unused. The battery is still operational, but only 50% of the initial efficiency. In order to avoid the threat of a "memory effect", have to be implemented the whole loading process (to fully charge and then fully discharge the battery) at least once every two- three weeks. To discharge the battery must be disconnected from the device connector, and should be allowed to operate it on until it ceases. This will ensure that the battery remains healthy.
11. What is the complete charge process (cycle)?
The total number of uploads show the number of times a battery can be charged and discharged. Every time you charge or discharge a battery a provisioning process, namely a cycle takes place. The upload number is very important in battery applications such as laptop batteries and batteries for emergency lighting operator. A Ni-Cd battery's full charge is around 500-1000, or can be multiple charge and discharge too.
12. Does it really help if I keep the batteries in the fridge?
Yes, but only if you keep them dry. The higher the temperature, the more ion hostels freely, that may drains the battery itself.
Primary batteries (D, C, AA, AAA, 9V, etc.) in a cool environment slow down the rate of this process. Therefore at every battery we can witness a longer shelf -life, even if it is not in use. Either way, if you do this way, it is important to keep the batteries dry as much as possible, in an airtight container in the refrigerator's driest part - for example, in the doorway. To exposure the battery to moisture in the fridge for a long time can cause corrosion inside the battery. When you remove the batteries from the refrigerator leave to warm up to room temperature before using them.
13. Can I use my old Ni-Cd battery charger to charge the new Ni-MH batteries?
No. With the new Ni-MH charger can be charged to the old Ni-Cd batteries, but should not charge Ni-MH batteries with Ni-Cd charger. The reason is the following: the Ni-MH and Ni-Cd batteries are chemically very similar, and when both are fully charged, the battery's voltage starts to decrease. This is the so called delta voltage (deltaV). The Ni-MH battery voltage is reduced much finer and it is much harder to detect. The Ni-MH chargers usually have an overheat sensor, which turns off to prevent overcharging and also have a sensitive voltage drop - sensor. The Ni-Cd chargers usually use only the voltage drop - sensor to determining the end of charge. If the Ni-MH battery charged in Ni-Cd battery charger, the charger probably will not detect the subtle tension reduction, and will continue to charge the battery which could lead to overheating. Overcharging and overheating can cause internal damage to the Ni-MH battery and reduces battery life.
14. DThe new laptop and/or camera battery does not work! What is the wrong?
The new batteries transported in discharged state, and have to charge them before use. Usually we recommend an overnight (about 12 hours) charge for the Ni-Cd batteries and 24 hours charging for the metallic hydrogen batteries. Please refer to the computer user guide for instructions on charging. Firstly the rechargeable batteries should be subjected to a complete charge process - that must be charge and discharge - 2-4 times to reach their full capacity.
(Warning: it is completely normal that the battery becomes hand warm during charging and discharging.)
