How to Rebuild a Laptop Battery

Level of difficulty: Intermediate

A laptop battery’s charging capacity regresses through time and use and this often goes unnoticed by any ordinary computer user. A laptop battery costs a lot. This is the reason why it is more practical to have the worn-out battery rebuilt rather than replacing it with a new one. A laptop battery consists of individual and distinct cells within the battery casing and these cells usually lose their efficiency through time and computer use. Replacing these cells rejuvenates the laptop’s function and efficiency by allowing the machine to have more charging capacity; hence, a longer period for usage.

Materials Needed:
- Xacto knife or Wirecutter
- new battery cells corresponding to the laptop’s battery
Step 1
The user must first completely drain the laptop’s battery prior to removing it from the laptop computer.
Step 2
Read the label on the laptop battery and look and read for the label of the battery pack. The battery label is usually located near the warning written on the battery pack stating 'Don’t do this and so on and so forth'. Within the same vicinity of this same warning, the battery pack’s model number can also be seen.
Step 3
Snoop on the battery pack’s cover somewhere near the Lithium Ion Battery Pack No. in order to reveal the battery’s individual cells. These individual cells are bunched up together within the battery casing.
Step 4
Search for the part number of the battery cells. This is usually printed directly on every cover of each battery cell. After finding the part number, search for the part number in the Internet to reveal the manufacturer of the battery cells.
Step 5
Use a wire cutter or a xacto knife to slowly and carefully separate the battery casing from their individual cells. Every battery pack is usually distinct from other battery packs so be very careful in disposing the old ones.
Step 6
Remove all the metal contacts on the battery until all that is left and appears before the user is a completely empty battery tray. Battery cells often come with wires connected to something. Not all wires have to be removed or disconnected in the battery tray. Only the black and red wires should be removed while the remaining wires should be left untouched in order to avoid accidental short-circuiting.
Step 7
Get the tops and coating from the old batteries. Slowly transfer them to the new batteries. Upon completing these steps, the user will have bare old batteries and fresh batteries that appear to be old.
