Note: After plugging your Allegro into the wall charger, check the
system tray icons and make sure the charge icon shows a small lightning
bolt next to it, verifying that the Allegro is charging.
Useful Life of a NiMH Battery Pack
Battery packs can be recharged approximately 600 times before they
need to be replaced. This number is dependent on the temperatures
they have been exposed to, operating conditions, and charging and
discharging practices. If the battery does not hold a charge for an
acceptable period of time, it needs to be replaced.
Recycling the NiMH Batteries
The NiMH batteries inside the Allegro battery packs are recyclable.
We are voluntarily participating in an industry program to collect
and recycle these batteries when they are taken out of service in the
United States and Canada.
The recycling program provides a convenient alternative to placing
used NiMH batteries into the trash or the municipal waste system.
Our involvement in this program is part of our commitment to
preserving our environment and conserving our natural resources. If
battery recycling is not available in your area, contact our customer
service to return spent batteries for recycling.
Spare NiMH Battery Packs
Spare battery packs should be stored in a cool location. Avoid
placing battery packs contact side down on a metal surface. Also,
do not stack packs so that their contacts touch one another. These
practices cause the batteries to drain. The shelf-life of a charged
battery pack is about three to fi ve years. Before using a spare pack,
you should fully charge it.
Short-Term Backup Supply
The Allegro has a super capacitor that behaves like a backup battery.
When the main batteries are removed, the capacitor maintains the
RAM for up to fi ve minutes. You need to change batteries within this
time period. The capacitor cannot operate the Allegro. The capacitor
is charged by the batteries. It holds a charge as long as the batteries
or external power are supplied. When a battery pack is replaced, the
capacitor charges up to full capacity in about two minutes.
If power is not supplied to the Allegro for more than fi ve minutes,
the Allegro resets when the battery pack is replaced or charged.
All the programs, data, and applications saved to the disk are safe.
Information that was not saved to the C_Drive is lost.
The super capacitor should not need replacement through the life of
the Allegro.
