National broadband users will have to pay for back-up batteries
The government said the battery program and an increase in the number of the National Broadband Network points of interconnect were among the most important decisions recently finalised. Cheap TOSHIBA PA3534U-1BAS Battery for toshiba laptop that uses pa3534u-1bas battery.
An increase in the number of premises covered by the NBN could push the cost of supplying back-ups above $163 million, up $13.5m from earlier estimates.
Battery back-ups are crucial. In case of a power outage, they ensure emergency phone calls can still be made over the new fibre network that will replace Telstra's copper lines.
The NBN Co corporate plan, released yesterday, says the company will "install a power supply unit, including a suitable HP Pavilion dv6000 Battery" for free at the time network termination units are fitted at NBN premises.
Once the free back-ups run out of juice, people would have to pay a retail price of about $40 to buy new lead batteries -- expected to last three to five years. "Maintenance of the battery, including replacement, will be the responsibility of the end-user or retail service provider," the plan says.
NBN Co has the buying power to purchase the Dell Latitude D820 Battery at wholesale rates -- expected to range from $8.20 to more than $13.50, according to the McKinsey-KPMG implementation study.
The study concludes that supplying 11 million phone subscribers with back-up batteries would cost taxpayers between $90m and $150m annually.
However, the NBN Co plan confirmed 12 million premises would be connected to the fibre network within 10 years.
An NBN Co spokeswoman would not say how much the additional one million premises would cost, but said battery back-ups were included in the $35.9 billion total capital expenditure for the network rollout.
"This information is commercially sensitive, as we have yet to implement a procurement process for battery back-up," she said.
"We cannot signal to prospective vendors what we expect to pay, but the costs were included in the capital expenditure estimate," the spokeswoman said.
NBN Co initially did not plan to subsidise back-up batteries but the government insisted it do so after industry concerns over users' ability to make emergency calls during a power failure.
When a blackout occurs, cordless phones don't work on Telstra's copper line and won't function on the NBN.
"Devices which require local power such as cordless phones or those connected to the NTU data ports will not operate during loss of mains power as they are not protected by the battery back-up solution," NBN Co's business plan says.

Choosing the right battery for industrial applications
Industrial applications have unique power needs and the choice of battery is important. While consumer products demand high energy density to obtain slim and elegant designs, industry focuses on durability and reliability. Industrial batteries are commonly bulkier than those used in consumer products but achieve a longer service life.
Batteries are electro-chemical devices that convert higher-level active materials into an alternate state during discharge. The speed of such transaction determines the load characteristics of a battery. Also referred to as concentration polarization, the nickel and lithium-based batteries are superior to lead-based batteries in reaction speed. This attribute reflects in good load characteristics.
Discharge loads range from a low and steady current flow of a flashlight to intermittent high current bursts in a power tool, to sharp current pulses on digital communications equipment, laptops and cameras. In this paper we evaluate how the various battery chemistries perform in a given application.
What's the best battery for video cameras?
Nickel-cadmium batteries continue to power a large percentage of professional cameras.HP Pavilion dv9000 Battery(hp dv9000 battery), HP EV087AA Battery, HP EX942AA Battery HP Pavilion ZT3000 Battery, This battery provided reliable service and performs well at low temperature. nickel-cadmium is one of the most enduring batteries in terms of service life but has only moderate energy density and needs a periodic full discharge.
The need for longer runtimes is causing a switch to nickel-metal-hydride. This battery offers up to 50% more energy than nickel-cadmium. However, the high current spikes drawn by digital cameras have a negative affect and the nickel-metal-hydride battery suffers from short service life.
There is a trend towards lithium-ion. Among rechargeables, this chemistry has the highest energy density and is lightweight. HP EV087AA Battery, A steep price tag and the inability to provide high currents are negatives.
The 18650 cylindrical lithium-ion cell offers the most economical power source. "18" defines the cell's diameter in millimeters and "650" the length. No other lithium-ion cell, including prismatic or polymer types, offers a similar low cost-per-watt ratio.
Over the years, several cell versions of 18650 cells with different Ah ratings have emerged, ranging from 1.8Ah to well above 2Ah. The cells with moderate capacities offer better temperature performance, enable higher currents and provide a longer service life than the souped up versions.
The typical 18650 for industrial use is rated at 2Ah at 3.60 volts. Four cells are connected in series to obtain the roughly 15 volts needed for the cameras. Paralleling the cells increases the current handling by about 2A per cell. Three cells in parallel would provide about 6A of continuous power. Four cells in series and three in parallel is a practical limit for the 18650 system.
Lithium-ion requires a protection circuit to provide safe operations under all circumstances. Each cell in series is protected against voltage peaks and dips. In addition, the protection circuit limits each cell to a current about 2A. Even if paralleled, the current of a lithium-ion pack is not high enough to drive digital cameras requiring 10 to 15A peak current. Tests conducted at Cadex Electronics have shown that the 18650 allows short current peaks above the 2A/cell limit. This would allow the use of lithium-ion on digital cameras, provided the current bursts are limited to only a few seconds.
What's the best battery for still cameras?
The power requirement of a professional digital camera is sporadic in nature.HP Pavilion dv9000 Battery(hp dv9000 battery), HP EV087AA Battery, HP EX942AA Battery HP Pavilion ZT3000 Battery, Much battery power is needed to take snapshots, HP EX942AA Battery some with a powerful flash. To view the photo, the backlit color display draws additional power. Transmitting a high-resolution image over the air depletes another portion of the energy reserve.
Most non-professional cameras use a primary lithium battery. This battery type provides the highest energy density but cannot be recharged. This is a major drawback for professional use. Rechargeable batteries are the answer and lithium-ion fits the bill but faces similar challenges to the video cameras.
What is the best battery for medical devices?
One of the most energy-hungry portable medical devices is the heart defibrillator. The battery draws in excess of 10 amperes during preparation stages. Several shocks may be needed to get the patient's heart going again. The battery must not hamper the best possible patient care.
Most defibrillators are powered by nickel-cadmium. nickel-metal-hydride is also being used but there is concern of short service life. In a recent study, however, it was observed that a defibrillator battery cycles far less than expected. Instead of the anticipated 200?cycles after two years of seemingly heavy use, less than 60 cycles had been delivered on the battery examined. 'Smart' battery technology makes such information possible. With fewer cycles needed, the switch to higher energy-dense batteries becomes a practical alternative.
Sealed lead-acid batteries are often used to power defibrillators intended for standby mode. Although bulky and heavy, the Lead-acid has a low self-discharge and can be kept in prolonged ready mode without the need to recharge. Lead-acid performs well on high current spurts. During the rest periods the battery disperses the depleted acid concentrations back into the electrode plate. Lead-acid would not be suitable for a sustained high load.
The medical industry is moving towards lithium-ion. The robust and economical 18650 cells make this possible.HP Pavilion ZT3000 Battery, The short but high current spurts needed for defibrillators are still a challenge. Paralleling the cells and adding current-limiting circuits that allow short spikes of high current will help overcome this hurdle.
What is the best battery for power tools?
Power tools require up to 50 amperes of current and operate in an unfriendly environment. HP Pavilion dv9000 Battery(hp dv9000 battery), HP EV087AA Battery, HP EX942AA Battery HP Pavilion ZT3000 Battery,The tool must perform at sub zero temperatures and endure in high heat. The batteries must also withstand shock and vibration.
Most power tools are equipped with nickel-cadmium batteries. nickel-metal-hydride has been tried with limited success. Longevity is a problem but new designs have improved. lithium-ion is too delicate and could not provide the high amperage. Lead-acid is too bulky and lacks persistent power delivery. The power tool has simply no suitable alternatives to the rugged and hard-working nickel-cadmium.
In an attempt to pack more energy into power tools, the battery voltage is increased. Because of heavy current and application at low temperatures, cell matching is important. Cell matching becomes more critical as the number of cell connected in series increases. A weak cell holds less capacity and is discharged more quickly than the strong ones. This imbalance causes cell reversal on the weak cell if the battery is discharged at high current below 1V/cell. An electrical short occurs in the weak cell if exposed to reverse current and the pack needs to be replaced. The higher the battery voltage, the more likely will a weak cell get damaged.
