What will cause my battery to lose power?
A battery over time degrades and eventually stops working. In fact
the battery from its very first charge begins a very slow process
that causes the battery to cease from functioning. Collectively the
process is called battery degradation and power loss and it
includes the following: declining capacity, increasing internal
resistance, elevated self-discharge, and premature voltage cut-off
on discharge.
Declining capacity is when the amount of charge a battery can hold gradually
decreases due to usage, aging, and with some chemistry, lack of
maintenance.
The loss of charge acceptance of the Li ion/polymer batteries is due to cell oxidation. Cell
oxidation is when the cells of the battery lose their electrons.
This is a normal process of the battery charge creation process.
The capacity loss is permanent because the metals used in the cells
run for a specific time only and are being consumed during their
service life.
Internal resistance, known as impedance, determines the performance and runtime of a
battery. It is a measure of opposition to a sinusoidal electric
current. A high internal resistance curtails the flow of energy
from the battery to a device. The aging of the battery cells
contributes, primarily, to the increase in resistance as does cell
oxidation. Interestingly energy may still be present in the
battery, but it can no longer be delivered due to poor
conductivity.
Elevated Self-discharge: All batteries have an inherent self-discharge. The self-discharge
on nickel-based batteries is 10 to 15 percent of its capacity in
the first 24 hours after charge, followed by 10 to 15 percent every
month thereafter. Li-ion batteries self-discharge about five
percent in the first 24 hours and one to two percent thereafter in
the following months of use. At higher temperatures, the
self-discharge on all battery chemistries increases. The
self-discharge of a battery increases with age and usage. Once a
battery exhibits high self-discharge, little can be done to reverse
the effect. Be sure never to leave a rechargeable battery at low
charge for long periods, even during storage.
