  • What Causes Lithium-ion to Age?
    The lithium-ion battery works on ion movement between the positive and negative electrodes. In theory, such a mechanism should work forever, but shelf life, cycling and temperature affect the performance. Because batteries are used under many demanding environmental conditions, manufacturers take a conservative approach and specify a battery life between 300 and 500 discharge/charge cycles. Life cycle testing is easy to measure and is well understood by the user. Some organizations also add a date stamp of three to five years; however, this method is less reliable because it does not include the type of use.

    Battery conditioning is the practical way to extend the Li-Ion battery capacity.
    Are you sure? This action cannot be undone.

    Most of the cell-phone manuals have a wrong take on this. They still ask to follow the old method with Ni-Cd cells, that is recharge the battery only after it is completely discharged. But this method does not hold good with 'Li' batteries which are used widely these days in cell phones and other portable devices. This sadly decreases the number of charging cycles.
