Why can not with the use of old and new batteries

Cells in the daily life of the population plays an important role, whether quartz, razor blades or a calculator, keyboard and so on without her. We had the experience is, the VGP-BPS10 VGP-BPS2 battery should replace all worn, should not be mixed with the use of old and new. Why is this? Is it not more to save the old works and new do?

To answer this question, we talk about the characteristics of the battery itself. Ordinary dry cell batteries have two very important characteristics, it is ε EMF in the circuit, we usually call the voltage U, the other is resistance R, because the batteries and, like all drivers have resistance. Typically, a new dry battery to the electromotive force of 1.5V, the resistance is approximately 0.5Ω. When the battery for a long period of time, electromotive force will be reduced to about 1V, while its internal resistance, but it may increase by several hundred ohms.

Because it is the battery internal resistance in the use we must also be taken into account. Take an ordinary flashlight is concerned, the use of two batteries so the power light emitting filament, when the normal resistance of about 10 ohms, according to Ohm’s law, one can calculate: FRU 92P1141 40Y6799

Circuit current is:

I = ε / (R + r) = 3V/11Ω ≈ 0.27A

The total power as follows:

Total P = Iε = 3V × 0.27A = 0.81W

Power light bulb obtained as follows:

P = I2R = lamp (0.27A) 2 × 10Ω = 0.74W

Power Efficiency:

Lamp η = P / P total = 0.74W/0.81W = 91%

Namely, the power consumption of the electric lamp on the vast majority do is meaningful work, the bulb is very bright. Dell Inspiron B130 battery  Dell Inspiron E1505 battery

Adjust the flow through the former, the electromotive force will be reduced to 1 V, internal resistance was increased to 200Ω. If the old and new batteries, used in the same way that we can calculate the yield of food to 5%. In other words, the power to make the most of current consumption in battery internal resistance alone, used to do useful work for some, not even light bulbs and light so very dark.

The foregoing analysis, we can easily see that the old and new batteries after use, not only can not, but it is a waste of energy. Therefore, the old and new F2024A F2024B batteries can be used with.

Total Station Battery Maintenance Experience

The batteries used in today’s total stations are generally two types: the special lithium battery and Ni-MH rechargeable batteries commonly used. Dedicated lithium-ion battery, lightweight, high capacity, environmental protection, virtually no “memory effect”, but the price is expensive, generic poor. Ni-MH VGP-BPS2 VGP-BPS2A battery is a high capacity battery discharge power of great depth, resistance to overcharge and over discharge, charging time is short and so obvious benefits. The most important is the nickel-metal hydride batteries are inexpensive and versatile.

No matter what type of battery, as the sale with the total station, generally, there will be training in the use of attention, some companies will even print a separate report on guidelines for the use of batteries and chargers. These instructions are some of the most basic but also very necessary to track maintenance as a method of recharging the battery should be selected, time to load. Unfortunately, many users of these instructions are often ignored or shelved. Recommendation: take a little time to read these guidelines, is absolutely necessary.

Users typically replace the PA3285U-3BRS PA3383U-1BRS battery, will acquire the habit of putting the battery in the way, wherever the place is clean and moist. The consequence is that the battery they get dirty easily, easy to contact metal (such as keys), etc. contact, easy to moisture, and it is the enemy of batteries. Recommendation: To avoid problems such as loss of electricity to keep the battery contacts clean and, if necessary, use a soft, clean and dry pasture.

A long time when you are not using total station, you must remove the battery from the machine and stored in a dry, cool environment. We all no objection to this point, but why here to make room for discussion? Because this relates to another question: For the Ni-MH F2024A F2024B battery, the battery must be completely discharged, then save, store, or online? Its two kinds of different views of what should be used? Many people think that we should adopt the first, but I thought that to save the battery charge is reasonable. Because: According to tests, Ni-MH battery to save the best conditions to save about 80% charged. Because the nickel-metal hydride batteries self-discharge high (10-15% a month or two), if the battery is completely discharged, then save it for a long time not to use, self Battery-discharge phenomenon will excessive battery discharge will damage the battery. You think of buying a new nickel-metal hydride rechargeable battery is not all there is electricity, which is the reason.

9 unique skills to save battery power on Win7 notebook

Microsoft recently announced a report entitled “Power Management win7″ the 14-page document white, describes the technology of power management, Windows 7 is the way to reduce power consumption. Windows 7 If you want to know how power and the White Paper will give you the answer. If you just want to look simple and fast, the following will tell you that the primary means of saving 6Y270 Windows 7.

1. Idle power consumption of resources

When a computer starts up, not always running at full capacity, there is a lot of downtime, downtime, energy consumption has become an important technology for energy management. The win7, the idle power consumption is effectively improved when a certain period of time the material does not enter into a state of low power has reached the goal of power. Including the CPU, hard drives, memory and network elements have adopted this technology. For example, a full power operation of the CPU power 35W power consumption during idle time is almost 0, only one will be able to save much power.

2. with the trigger to start the service

System services are generally a time when the system starts at the beginning, and then resides in the background awaiting F2024A appeal. In Windows 7, the part of the service system can not be started until a few triggered by events such as the insertion of a device or change the IP address. This can reduce the lengthy process context where the number of services.

3. Improved power management processor

win7 Village incorporates the latest technology in power management that allows Windows 7 in terms of conditions of the current load and performance requirements to dynamically adjust processor performance.

4. Adaptive adjusting screen brightness

Microsoft said that, usually 10-15 minutes time if no operation, the screen turns off automatically. But in practice, it will be more short-term use of non-operating conditions for improved energy efficiency, technology will reduce the brightness of the screen. In addition, he can enjoy a number of sensor devices to adjust the VGP-BPS2 brightness according to ambient brightness display.

5. Low-Power Audio

Win7 support for low-power Intel HD Audio specification, it allows the codec to enter a low power state. Win7 also supports the selective suspension technology, is in idle state device is turned off, such as microphones and cameras of this type of USB devices.

6. Integration Timer

The current CPU instruction address space by the use of free time to saving energy use, but most energy saving technologies require a certain period of idle time for the energy effect of economy. And this technology by making the Windows kernel at the moment and focus on the termination of the original dispersed multiple timers are eliminated in a short period of time, increasing the downtime of the processor.

In addition, when using the laptop batteries.org/”>battery cases, win7 would reduce the activities of non-critical frequency processes background.

7. Bluetooth devices to improve energy

When win7 detected Bluetooth devices in a state of low power, as they were temporarily closed, ie “selective suspend.”

8. Network equipment to improve energy

win7 in the radio network controller to compatibility mode for low power has been strengthened, and only in the wireless AP devices support low-power mode where only the opening. Vista, because it could not detect in advance whether to support low-power mode, will lead to a sudden interruption of the wireless network connection. Win7 will prevent this from happening, before entering the low power mode will first be tested as to whether the mode of the wireless toshiba-pa3191u-3brs-battery-p-30278.html”>PA3191U-3BRS AP.

9. Typical applications of the optimization program

In addition to the improvements listed above, Microsoft has also turned to specific applications, including search, browse without networking and small game. Here is optimized DVD playback program Part of the occasion:

Without affecting playback performance, according to the principle of maintaining the low power mode so that CPU

By changing the structure to improve manager’s office window and consumption of the GPU

Data caching can intelligently reduce the driving speed

These are the win7 in power management, 9 significant improvements compared to the previous system can save more energy. In addition to these improvements, professionals can also be diagnosed with the management of energy research in May that affects the A1008 efficiency of the problem.

How to take care of the laptop battery

In fact, the problems of Laptop battery, and not simply because manufacturers must design and manufacturing problems. In addition, users in the process of use is incorrect, could cause the battery problem. Therefore, the proper use of laptop batteries are worthy of our consideration.

First, we must properly enable the new battery. Want your laptop battery life, you must be a good start, who spoke of buying the book.

The new laptops in the first start with the battery should be 3% of electricity (which is also a common practice of companies. If you bought the notebook open for the first time and found that the battery is already full, must have been used by others). At this point, you should not use external power, the Dell Latitude D510 battery inside the power more than exhausted, to rest, then the reuse of a charge of external power.

At the same time, we must remember that the first 3 times the charging time must exceed 12 hours, to enable efficient battery to lay a solid foundation for future use.

Secondly, to reduce the number of batteries to use external power. Also, use an external power supply when the battery removed. Friends Chart convenience is often the case with the battery supplying several Plug Power, much damage to the battery. Because each access to external power is equivalent to charging time of battery, battery by a shortened course.

However, so long does not use batteries, can cause cellular aging. I suggested a longtime friend does not use batteries, the average charge and discharge once a month.

Again, the power exhausted after charging, they also want to avoid the loading time is too long. Whether your laptop to use nickel-metal hydride or lithium-electric power, he must take charge after the exhaustion of power is the best way to avoid memory effect. When you charge the hp F2024A battery for the laptop, try to avoid the time is too long, the overall control within 12 hours.

Finally, when your laptop battery is charging, the best people in the other guard, found that abnormalities immediately cut the power off. Try to avoid the moment when no one can charge the battery, but do not sleep when the battery charge.

As for prevention of exposure to prevent damp to prevent erosion of liquid chemicals, avoid contact with battery contacts with metal objects such as attention, not much to mention here too.

In fact, all laptop battery, for any use of the battery, such as cellular phones, digital cameras, batteries, battery science is very important.
