In this article the author by analyzing the composition and laptop batteries(thinkpad x60 battery , thinkpad x60s battery , thinkpad x61s battery) are designed to help people from the current market in the notebook battery business of price and other considerations to choose the best laptop batteries.

Laptop battery is a lithium-ion 18650 cells 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, a typical thinkpad x61s battery with eight cells 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 different in the U.S. according to the capacity of 3 yuan 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 notebook 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 notebook assembly of low-quality products, its eight batteries in laptop battery costs can be 50 yuan .

2. With regard to the control panel PCB laptop batteries, a good control panel, you can extend thinkpad x60s battery life to protect the safety, its cost is usually 80 yuan; if it is bad dysfunction PCB battery control panel, or disassemble panels, cost 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 notebook battery (8 cells) costs should be around 280, so a good non-first wife laptop batteries (thinkpad x60 battery ,thinkpad x61s battery) and a lower price, including operations cost and profit to reach the end consumer’s hands should be 350-550 yuan; 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 cells) costs for 80 or so, its price is usually between 100-200.

Before I file a complaint, the outrageously expensive part now, Sony needs to get it one last chance. The house Vaio Power Management tool (see screen) you can activate namely, a “battery care”. This is apparently the thinkpad x60 battery only to 80% each (or less, charged depending on the setting). This has probably lead to a lower wear. At least I take the somewhat meager description in the corresponding menu of the software. Perhaps this will solve my problem?

If not, this would have the 2nd Return / reclamation of this equipment. The last time was in the course of recalling changed the webcam, because it could lead to the inspiron 1501 battery overheating. Still, it went very quickly (2 days donated) and Sony, as a consolation a USB stick with 2 GB, which makes since to me in the car well.

But if the thinkpad t60 battery is really scrap, I probably bad deal anyway. Since one gets from a maximum of 6 months after purchase or to grace a replacement. So only the hope remains that the laptop ansich somehow draws electricity when it is switched off or in sleep mode. That should indeed not normally be the case
