UNDERSTANDING LITHIUM-ION BATTERIES
Rechargeable lithium-ion batteries have quickly become the emerging
standard for portable power in consumer devices due to their light weight,
high energy density, lack of memory effect, and charge longevity. They are
also more environmentally friendly as they do not contain toxic materials
such as Cadmium or Mercury.
Understanding common phenomenon with rechargeable lithium-ion
batteries can help you better care for your Battery Pack and answer many
common questions regarding usage.
Lithium-ion batteries do not suffer from the memory effects that are
associated with other types of battery chemistries. This means that
the battery does not need to be completely discharged before charging.
Upon initial use or after a prolonged storage period, lithium-ion
batteries may require 3-4 charge/discharge cycles before achieving
their maximum capacity.
Lithium-ion batteries will self-discharge when unused; therefore, it
may be necessary to recharge the battery after a storage period.
The amount of charge lithium-ion batteries will hold will gradually
decrease due to usage and aging. Over time, the actual battery capacity
decreases as less and less active material within each lithium-ion cell
is available to electrochemically store a charge. This loss in capacity
(aging) is true for all rechargeable lithium-ion batteries.
It is normal for a lithium-ion battery and its AC power supply to
become slightly warm to the touch during charging and discharging.
BATTERY PACK STORAGE
Charge to approximately 40% of capacity before storage.
Store in a dry, cool place away from heat, direct sunlight and
metal objects.
