In the knowledge of DIY notebook batteries and maintenance method
Laptop battery replacement
Recycling methods can be used to extend PP2100 battery for quite a long time to solve this problem, in addition to replace the battery (used batteries are very difficult to find the same model), we can also change the battery core. But it also needs to learn more knowledge, with strong battery operation skills. Below is still my notebook computer batteries, for example (notebook computer model is the FMV – 575NU Fujitsu/Y), introduces the replacement battery.
The notebook computer batteries and have two sets of battery power machinery, but using a multimeter laptop battery storage spring contact tests found that -products “+” and “-” metal contact touch edition of the two springs are interlinked, means the batteries are actually two machines in parallel to Presario R3000 (R3000 compaq battery) power supply.
The battery blade on the side of the slit carefully cut open, and found that the batteries battery box 16 monomer, from a single cell voltage and capacity, respectively, 1000mA 1.2 V. Although it’s shape and dimension, generally in the 5th, like nickel cadmium battery, but with – the capacity of the battery market to can not find. Finally, second-hand computer stores to find a 575NS/L Fujitsu FMV – the notebook computer batteries, labels can be seen from the shell of lithium battery (lithium battery voltage 10.8), 2400mA, capacity of V. At the same time, my laptop battery voltage, Fujitsu, but Presario X6000batteries capacity, in their essence is some differences, can replace heart yet, but still spend 180 yuan to buy it.
Home lithium battery cut open, bypass circuit, remove battery monomer, o. 1200mA, 6V single-celled parameters), according to the original permutation of circuit batteries and parallel, then tape tied into a whole notebook computer batteries and six of the battery. From the notebook computer batteries in these two “+” are connected to a touch – choose film, with its battery wires connected to actively, and choose the one with the “-” connect battery anode and spring contacts. Finally, we need the notebook computer linked to two labeled “T” metal interface of the electronic components (the components of notebook computer batteries ZV5000 pavilion ZV5000 (HP) as part of the battery for detecting circuit connected to the notebook computer batteries) removed, solder corresponding position in the spring of laptop computers on the components (if not, use the laptop battery power, the power supply in self test will appear after period of time, the machines automatic shutdown phenomenon). Of course, these business should be closed.
