Looking for the longest battery life laptop ?


We’ve yet to see a Windows laptop with battery life longer than 5~7 hours, unless we add an extended battery to the system. But when hpand dell launched its new series of laptops last week, one big push wasfor longer battery life.

When you purchase your notebook, charge the battery to 100 percent,discharge it completely, and then fully charge it to 100 percent againto help the battery remember exactly how much electrical charge it canhold. From then on, you’ll never need to completely discharge the laptop battery again, but always make sure when charging it that you let it reach 100 percent. DeHoop told us to “remember to plug in the laptop AC adapter(or dock/port replicator) whenever you get a chance. Most notebookswill recharge quickly.” Salinas had another tip for your batteries:“Keep them cool. Exposure to high temperatures can be a battery’s worstenemy,” he said

Hope the list can give you some help when you purchase a laptop or battery:

How to Open a Laptop Battery & Replace the Lithium Ion


Laptop batteries, like all rechargeable battery packs, lose their charging capacity over time. Because new Laptop batteries are expensive, replacing the individual cells inside the battery casing can save a lot of money. However, rebuilding a battery sometimes does not work as expected, so it’s important to be willing to purchase a new laptop battery if the procedure fails.

1、Allow the laptop battery to run down completely. Turn off your laptop, then remove the battery. Write down the model number located on your battery to help identify the type of Li-ion replacement cells you need to purchase.
2、Split open a small section of the laptop battery pack (at the seam) with a screwdriver or craft knife. Continue to pry the plastic case loose moving around the outer edge until the entire top is free. This may take a bit of force.
3、Note the number of cells inside the case (usually four to eight). Write down the part number and voltage information printed on the cell casings. Draw a diagram showing the arrangement of the cells and how they are connected, or take a few photos to help with reassembly.
4、Purchase the correct number and type replacement batteries from online shop such as udtek.com, based on your battery model and cell specifications. Six Li-ion cells typically cost around $30 to $40.
5、Carefully remove each cell using a craft knife and wire cutters as necessary. Each battery pack is different, but the cells are usually wrapped in a plastic casing with metal contacts attached to one end. Lay the metal contacts, wires and casing material aside.
6、Use double-sided tape or a solder gun (only if necessary) to attach the metal contacts to the cells and circuit board. When finished, the old cells should be completely stripped (naked) and the new cells should look like the old ones as much as possible.
7、Place the new cells inside the case, referring to your diagram or photos if necessary. Glue the battery(Compaq DV6000 Battery) pack top back on. Charge the new battery for at least 24 hours before using it.
Tips & Warnings
Keep an eye on the new battery while it charges for the first time. If the contacts are not connected properly, the battery could overheat and cause damage to the laptop.

    Dell Inspiron 6000 (approx 4 years old) has an issue with the power cord internal connection? Battery and Power cord/adapter are fine. Computer constantly switches from battery to AC when powered on. ...


    The input jack that is soldered to the motherboard (where the AC jack plugs in) probably has a cold solder joint. Thus the laptop switches from battery to AC power. You can try to have the solder joints
    re-soldered.
