Replacing The Lithium Ion Battery

The lithium-ion battery is a family of rechargeable battery types that the lithium ions  can move from the negative electrode to the positive when discharging, and back when charging. The lithium-ion battery has a variety of performance, safety and cost characteristics. Unlike lithium primary batteries that are disposable, lithium-ion electrochemical cells use an intercalated lithium compound as the electrode material instead of metallic lithium.

Lithium-ion batteries are quite common to be used as laptop battery. They are one of the most popular types of rechargeable battery for portable gadget, like laptop with one of the best energy densities, no memory effect, and a slow loss of charge when not in use. Beyond consumer electronics, the lithium-ion battery are also growing in popularity for military, electric vehicle, and aerospace applications. Now with the research on traditional lithium-ion battery technology, it has made great progress on durability, energy density, intrinsic safety. However, its cost is still high.

Laptop lithium-ion batteries, like all rechargeable battery packs, lose their charging capacity over time. Because new laptop batteries are quite expensive,especially for Inspiron 1526 Battery and  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. If you are interested in it, you can see the instruction below for your reference.

All you should do first is to 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. And then split open a small section of the 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, which you may put forth your strength.

After that, you must note the number of cells inside the case. 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 reassembling. Next you should buy the correct number and type replacement batteries from the electronic online store, like hootoo dot com, based on your battery model and cell specifications.

Once get it,  do 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. And then 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. Finally, just place the new cells inside the case, referring to your diagram or photos if necessary. Glue the battery pack top back on. Charge the new battery for at least 24 hours before using it.

At last, do notice that 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.
