Replacement laptop battery cell

With the capacity recovery method can only be used to extend the PP2100 battery for some time, to solve the problem, in addition to replace the entire battery outside the (second-hand laptop batteries is very difficult to find the same model), we can also change the battery core. But it also requires you to understand more of the battery knowledge, with a stronger operating skills. The following is still my notebook computer batteries, for example (notebook computer models is Fujitsu's FMV-575NU / Y), introduced the replacement battery cell.

While the notebook computer batteries at the same time there are two sets of batteries to power the machine, but with the multimeter test laptop battery store spring touch films, found the battery marked "+" or "-" the metal of the two springs in contact Touch tablets are interlinked, meaning that the battery is actually two machines in parallel to the Presario R3000(compaq r3000 battery) power supply.

Battery with a blade along the slits on the side of the battery carefully cut open and found the battery box a total of 16 monomers, which can be converted out of a single cell voltage and capacity, respectively: 1.2V, 1000mA. Although its shape and size and the general on the 5th, like nickel-cadmium batteries, but with the capacity of the battery on the market can not find. Finally, a second-hand computer store to find a Fujitsu FMV-575NS / L notebook PC batteries, the label can be seen from the shell of the battery is Li-ion battery (Li-ion), voltage is 10.8V, capacity is 2400mA. And my laptop battery while also Fujitsu, but the voltage, capacity and Presario X6000batteries are some discrepancies in their nature, can replace the heart has not been at the end, but still spent 180 yuan bought it.

Home to the lithium battery cut open, rounding the circuit board inside, take out the battery 6 monomer, its single-cell parameters are: 3.6V, 1200mA), according to the original arrangement of the circuit board to the battery 22 in parallel, and then in series, using adhesive tape to six batteries tied into a whole and into the notebook computer's battery warehouses. From the notebook computer batteries in the two positions with the "+" connected to a spring-touch film arbitrary choice, use it with the battery wire connected to the positive; also choose one with the "-" connected to the spring touch tablets and batteries connected to the anode. Finally, we need the original laptop batteries connected to the two labeled "T" word of the metal interface of an electronic component (this component is estimated notebook computer Pavilion ZV5000(hp zv5000 battery) as part of the battery identification circuit for detecting whether the battery connected to the notebook computer) removed, solder the corresponding position in the notebook computer touch of spring on-chip (if not this component, use the battery to the notebook computer power supply, the Power On Self Test will appear after some time the machine automatically power off of the phenomenon). Of course, these operations should be carried out in the shutdown state.
