Breaking the battery apart was probably the single most painful moment of this entire article

There will come a day when the rechargeable laptop and not charge and instead serve better as a paper weight. As the battery is used more frequently, the battery will lose capacity more and more until finally not accept a charge and goes flat. Battery replacement is easy, but the price of the new battery could be so strong that costs more than the laptop is worth. Buying a refurbished battery can lower the price even lower, but what if you are super cheap? Well, we cover this last option, which means that is destroying the old battery and fix it yourself.

Disassembly process



Breaking the battery also was probably the most painful moment of this entire article. I had no documentation to work, the plastic halves of the battery were glued together, and all I had was a sniper mini. I started to take off the sticker on top open exposing the cells under the light. After that I took my little pruning shears for plastic, and cut the small piece by piece until the entire top was removed. I had black plastic bits flying everywhere, I think anyone can even drink. The end result was a battery for dell latitude d830 box that is brutally to 100 percent safe for future use.



Once all the excess plastic was removed, the cells could be replaced. All these were glued in place, so prying with a screwdriver was the only option. As I slowly lifted each group form the plastic case without shorting any circuits, I took my clippers to the metal bridges to fully disconnect the batteries. During this time he also made special mention of the wires out of the charging circuit and where they connected for future use.



Finding the right replacement cells



Who would have thought finding something as simple as batteries US18650BR would be so hard? In reality, it took two of us about 30 minutes to find a site selling equivalent batteries. Now the standard name for the battery size we were looking for was 1650, and took one at random, as there were plenty of options to choose from ... and I was too lazy to run the calculations on the correct cell capacity. With the selection of cell blocks in the batteries, and sat patiently until he arrived.



Build Day



Once the new batteries arrived at the office, I worked on preparing to install batteries. I have checked the battery orientation of the images of the old assembly, and began to weld together the pairs of cells. I used some old wire to bridge together each group on the positive and negative, and coupled to the battery for the first time the red power cable. The next step was soldering together the second group, bringing back the first group, and solder the two leads the charge in place. Past was the third group of soldiers to the back of the second, and setting the black wire to the back of the battery group. The end result does not instill much confidence in a non-firey demise, but it ended. To add a layer of security that puts a bit of packing tape on the battery groups exposed, and mashed the "reconstruction" of the battery in the bottom of the notebook. To the surprise of all around me, the battery will not turn into a ball of flames, and actually started charging.
