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 is 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.
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.
One thing that can cause that whole problem to be avoided is to keep spare laptop batteries. This allows one to be charged while the other is being used. This makes it an excellent alternative for people who are going on long trips, or are going to be in long meetings and won't be able to charge their battery. It just takes a moment to change out one battery for the other and the laptop is ready to go for another few hours.
Another benefit of the lithium-ion Toshiba laptop battery is that it doesn't have any memory. This refers to an effect that many rechargeable batteries have. Each time they are charged and drained, they "remember" how far that charging goes, and how far down they are drained. If the battery doesn't get fully drained every time it gets used, it starts charging only to that level. For example, if it only gets drained 90% each time it gets used, after some time it only charges to 90%. Eventually, the effective use life of the battery gets down to the point that it can't be used without being constantly hooked into a charger but li-ion laptop batteries don't have that problem. They do not need to be fully drained to be recharged and they will always empty and charge to their full extent.
