Acer Squ
Rebuilding A Laptop Battery
When your acer aspire 1350 battery is about to give up the ghost, you are probably thinking of the typical three alternatives. The most obvious, of course, is “wow, what a great justification for buying a new laptop”. With laptop prices falling and no such luck with battery prices, this almost makes sense. But, most of us will probably just bite the bullet and buy a new battery. The third alternative would be to replace the cells in the battery you already have.
This article is about the third alternative. If you are not fairly skilled in working on electronics, this is not necessarily a good alternative. But, it is possible. Personally, I was inspired to do this the first time because the small (3-cell) battery for my ASUS laptop was very ill and I couldn’t find a replacement.
Financially, it also looked like a good choice. The out of stock new battery cost $129. I found the cells for a bit over $5 each. So, I ordered the cells and, expecting to have a success, ordered six more for a sick battery for one of my T23 ThinkPads.
The first trick is to open the old battery without destroying the plastic or anything important inside. What you need to do is find where the two parts are glued together and work on the glue line with something sharp until you can open the battery.
In the case of ThinkPad 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 acer squ-302 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 18650. Typically they are in strings of three in series (that gives you about 11V) and then each string is paralleled. But, that may not be the case. Do a bit of analysis before you start cutting wires.
Note that the cell size is not something that indicates that there are at least 18,649 other choices. It is actually the diameter of the cell in millimeters (18) followed by the length in millimeters (650). The big advantage with this system is that if the cell isn’t marked with a size, a metric ruler can help you out.
As Li-ion batteries need special “care and feeding”, you will find a circuit board within the battery pack, Wires will go from the circuit board to each cell junction so that the voltages can be monitored. Also, there will be a thermistor and a thermal circuit breaker within the pack.
There are lots of places that sell replacement Li-ion cells. One is Battery Junction. On their site you will find all the common acer aspire 1510 battery sizes. They also have both PC boards to protect sets of cells and a special 18650 cell with a built-in protection circuit. Assuming you are replacing cells in an existing pack, you just need to buy regular cells. One thing you do need to watch for, however, is tabs. Typically you can ask to have solder tabs spot welded to the cells. This is the right way to go rather than trying to solder directly to the cell which could easily damage the seals.
