batteryIn this article the author by ibm thinkpad t40 battery analyzing the composition and laptop batteries are designed to help people from the current market in the laptop battery business of price and other considerations to choose the best laptop batteries.
Laptop battery is a lithium-ion 18650 batteries with protection circuit board and PVC plastic shell composed of the following items on an analysis of their costs:
1. 18650 lithium-ion battery is divided into three kinds of 2200,2400,2600 mah, IBM ThinkPad R50 Battery a typical laptop battery with eight batteries to assemble (4 strings and 2). If it is a genuine original batteries, typically Japan and South Korea or domestic manufacturers A regular grade 18650 batteries, these batteries have the quality assurance and safety through rigorous testing, the cost is usually based on the different capacities in the U.S. 3 per between about 1, a normal laptop battery (8) costs around 24 U.S. dollars, equivalent to RMB: 170 or so. If B grade, or disassemble batteries (installed after a good quality of the batteries, Japan and South Korea have quality and even safety issues batteries, often in China, dumping) their cost price of between 10-15 yuan Such batteries assembly or re-assembled after an eight batteries of laptop batteries cost 80-120 yuan. In addition, even worse, some manufacturers with more poor illegal 18650, often have security problems, it is easy to blast away with your laptop assembly of low-quality products, its eight batteries in laptop battery costs can be 50 yuan .
2. Laptop battery on the PCB control panel, a good control panel, you can extend laptop battery life to protect the safety, its cost is usually 80 yuan; if it is bad dysfunction PCB battery control panel, or disassemble board, the cost of 30 yuan,
3. With regard to PVC plastic shell, the cost of a good plastic shell of 30 yuan, a bad low-quality goods, at 10 yuan.
Integrated on the complaint, there is a good quality assurance by the laptop battery (8) costs should be around 280, so a good non-first wife laptop batteries (8 batteries) and a lower price, including operations cost and profit to reach the end consumer’s hands should be 350-550 yuan; IBM ThinkPad T43 Battery if it is low-quality goods, B laptop battery (8) costs 120 yuan, the price for 200-300; if it is the lowest quality of laptop battery (8) costs for 80 or so, its price is usually between 100-200.
these new inventions.
Shoujimodian we supposed in? Do not worry, the latest research and development of independent brands “Hubei-made” mobile phone just to wear a
“wrist”, and body temperature can be used to charge their battery phones. Recently, Hubei Chen Holdings Limited Alliance
Shoujimodian, and will no longer have to worry about missing important calls. ibm
thinkpad a30 battery Wear a plastic “wrist”, plus a USB port, they can charge a mobile phone, IBM ThinkPad T43 Battery, IBM ThinkPad R50 Battery, IBM ThinkPad R51 Series Battery, and very environmentally friendly,
convenient. The technology has matured, the product
Is expected to launch later this year.
Dragon Wei told reporters, “wrist” is the use of human body temperature and room temperature, temperature difference, so that e-flow
generated voltage difference (requires 7-8 ° temperature difference), IBM ThinkPad R51 Series Battery and then converted into electricity to charge their battery phones on
the wristband micro-USB access
Head is responsible for the transmission of electric power bridge.
