Li-Ion Batteries
The Li-Ion batteries used in the XO-1 and XO-AP are
excellent batteries for portable, outdoor applications.
They have a high energy density (energy per weight)
compare to other rechargeable battery technologies
(NiCd, NiMH, Alkaline, Gel Cells), are low
maintenance, and offer superior performance at low
temperatures.
For best performance after long-term storage, Telex
recommends the batteries be charged to 30% - 50% of
capacity before being placed in storage. This is the
typical battery capacity left after a sporting event, such 
as a football game. Li-Ion batteries retain nearly all
their capacity, after longterm storage, if stored in dry,
cool temperatures with only 30% to 50% charge. They
can lose up to 20% capacity if stored for long term
right after being fully charged.
It is also a good idea to charge the XO-AP and XO-1
batteries once every 6 months for three hours then take
off charge. Do not fully charge. This helps to maintain
the battery's performance and prevent any
over-discharging.
