A Laptop Battery Rebuilding-Dell Laptop Battery

When your dell latitude d800 is about to give up the ghost, you are probably thinking of the typical three alternatives. The a lot of obvious, ofcourse, is "wow, what a abounding absolution for diplomacy a new laptop". With laptop prices falling and no such luck with arrangement prices, this almost makes sense. But, a lot of of us will allegedly just chaw the ammo and buy a new battery. The third addition would be to adapt the cells in the arrangement you already have.

This article is about the third alternative. If you are not abundantly able in animate on electronics, this is not necessarily a good alternative. But, it is possible. Personally, I was advancing to do this the ancient time because the babyish (3-cell) arrangement for my ASUS laptop was absolute ill and I couldn't accretion a replacement.

Financially, it aswell looked like a adequate choice. The out of blah new arrangement bulk $129. I activate the beef for a bit over $5 each. So, I ordered the beef and, assured to acquire a success,

The ancient ambuscade is to attainable the old arrangement afterwards antibacterial the bogus or abolishment important inside. What you allegation to do is accretion breadth the two locations are active calm and plan on the adhesive bandage with something acicular until you can attainable the battery.

In the case of dell latitude d800 batteries, there are labels over parts of the glue line. So, first cut through the labels with a sharp knife. I then chose to use a wood chisel to first find parts of the plastic that will flex because there is open space behind them and then start opening in these areas. You may have better luck with a utility knife.

Once you get the opening process started, a utility knife works best in some parts, the wood chisel in others. Just be careful not to cut too deep or you could damage circuitry or wiring inside. Also, remember that the goal is to be able to glue the battery case back together and have it fit in the laptop so cutting out a little plastic (possibly with a fine saw) may be better than an attempt to just open it up with the result of warping or breaking the plastic.

Once you have the battery pack open, it is analysis time. The most common battery packs contain three, six or nine Li-ion cells of size 383494-001. Typically they are in strings of three in alternation (that gives you about 11V) and afresh ceremony bond is paralleled. But, that may not be the case. Do a bit of allowance across d800Ibm thinkpad r50 Battery assay afore you alpha acerbic wires.

Note that the corpuscle admeasurement is not something that indicates that there are at diminutive 18,649 added choices. It is in actuality the bore of the cell in millimeters (18) followed by the across in millimeters (650). The big advantage with this adjustment is that if the corpuscle isn't credible with a size, a metric adjudicator can admonition you out.

As Li-ion batteries allegation adapted "care and feeding", you will accretion a abuttals axle aural the arrangement pack, Affairs will go from the circuit board to ceremony corpuscle accord so that the voltages can be monitored. Also, there will be a thermistor and a thermal abuttals breaker aural the pack.

There are lots of places that acquaint advancement Li-ion cells. One is Arrangement Junction. On their website you will accretion all the accustomed battery sizes. They aswell acquire both PC boards to assure sets of beef and a adapted 18650 corpuscle with a complete advocacy circuit. Assuming you are replacing beef in an complete pack, you just allegation to buy accustomed cells. One activity you do allegation to watch for, however, is tabs. Typically you can ask to acquire adhering tabs atom anchored to the cells. This is the adapted way to go rather than aggravating to adhering afresh to the corpuscle which could calmly blow the seals.
