How to rebuild a Li-Ion battery pack

Did you recently notice poor performance of your notebook Li-Ion battery?. Don't be taken aback, this is happening even to the best battery! Now days Li-Ion batteries are widely used in portable devices due to there excellent energy to weight ratio and for the reason they are not suffering from "memory effect".

These two reasons make them the best choice on portable devices, but not suffering from "memory effect" doesn't mean it will last for ever! Chemical conversions inside the battery make it to produce electric energy but these chemical reactions aim to attenuate as time and charge cycles pass over.

When the battery life drops significantly it's time to search for a replacement, but you will recently find out that most of notebook batteries cost almost 1/3 to 1/2 the price of the laptop at the time you will need to replace the battery. So if you want to keep your laptop but don't want to spend much money for battery replacement it's time to think about rebuild it your own, replacing each individual cell inside the pack.

A Russian Colonel story that prevents Word War III

Lieutenant Colonel Stanislav Petrov was the officer on duty at the Serpukhov-15 bunker near Moscow on September 26, 1983, a time when the Cold War was at a peak: just three and a half weeks prior, the Soviets had shot down Korean Air Flight 007, killing all 269 people on board the Boeing 747. It was Lt. Col. Petrov's responsibility to observe the satellite early warning network and notify his superiors of any impending nuclear missile attack against the USSR. In the event of such an attack, the Soviet Union's strategy was to launch an immediate all-out nuclear counter-attack against the United States, as the doctrine of Mutual Assured Destruction required.

REGRETS [Cambridge]

Regrets: a public conceptual artwork

Six to ten purpose-built mobile computer stations publicly located in and around Cambridge collect anonymously submitted regrets from the public to comprise a sociological database of contemporary remorse. Instant feedback to the individual user based on other contributors' similar concerns is algorithmically generated and calculated to 'share the burden'. Random selections and groupings of the regrets are made public across the city through existing signage and broadcast facilities. By engaging users in revelations of a problematic but constructive nature, we aim to bring specificities of individual lives, in this case personal regrets, into the realm of public debate, shared learning, and community.
