IMPRES BATTERY SYSTEMS
state-of-the-art IMPRES technology allows communication between the battery
and the charger. The result is a radio system thats charged and
ready to go whenever you need it.
battery maintenance - Manual tracking and recording of battery use are
a thing of the past. IMPRES uses a unique communications protocol to facilitate
adaptive reconditioning the charger evaluates the details of the batterys
usage pattern to determine the optimal reconditioning interval. This automated
process works to diminish memory effect and optimize the cycle life of the
battery and maximize talk time
that communicate - IMPRES multi-unit chargers are available with a two-line
display module. Your customers have access to valuable information such as:
Battery capacity (in mAh and percent of minimum rated
capacity) and voltage while charging and at completion of charge
Time remaining to complete rapid charging (NiCd and NiMH
Current battery charge status
The batterys unique serial number, part number and chemistry
is power - Now you can make informed decisions on battery replacement
and asset management
friendly - IMPRES chargers have technology that avoids overcharging and
our single-unit IMPRES chargers with external power supplies consume 40 percent
less energy in standby mode than required by the U.S. Energy Independence
and Security Act of 2007.
Long-term safe charging - IMPRES batteries may be left in IMPRES chargers
for extended periods without heat damage due to the charger and will be monitored
so that they are charged and ready to go whenever they are needed.
- Support for
mixed battery inventories - IMPRES chargers are compatible with non-IMPRES
Motorola batteries, making the migration to all IMPRES much easier. However,
automatic reconditioning and all other IMPRES features are realized only when
using Motorola IMPRES batteries and chargers.
warranty - When used exclusively with IMPRES chargers, IMPRES batteries
carry extended capacity warranties that continue six months longer than Motorola
Premium battery warranties.
- Proven tough
- IMPRES batteries are subjected to the same rigorous testing and held to
the same high standards as all Motorola Premium batteries. Actual results
of Drop, Vibration and ESD (Electrostatic Discharge) tests prove that Motorola
batteries outperform the competition.
- IMPRES products
are smarter because they talk to each other
Motorolas industry-exclusive IMPRES technology allows communication
between the charger and the battery, which enables automated battery reconditioning,
display of critical charging information and other key benefits. IMPRES batteries
have a memory chip that stores all usage information, which can then be accessed
and evaluated by any IMPRES charger. IMPRES chargers have built-in reconditioning
capability that is automatically utilized any time an IMPRES battery requiring
maintenance is inserted.
- IMPRES chargers
perform adaptive reconditioning
Before the availability of IMPRES chargers with automatic, adaptive reconditioning,
battery maintenance technicians had to guess at the correct reconditioning
intervals. Reconditioning too often wasted battery cycles; not reconditioning
often enough resulted in diminished battery performance. IMPRES has changed
all that. IMPRES chargers evaluate the actual usage pattern of every battery
to establish the optimal reconditioning interval.
- IMPRES offers
long-term safe charging
Most conventional chargers transition to a maintenance charge mode at the
completion of a charge cycle. Maintenance charge is constant power applied
to a battery in an effort to keep it charged over time. This results in long-term
heating that can damage a battery, resulting in lost capacity. IMPRES chargers
automatically turn off at the end of a charge cycle yet continue to electronically
monitor IMPRES batteries every 5 minutes to determine when more energy should
be applied to the battery. This process assures that the battery maintains
a very high state of charge without sustaining heat damage due to the charger.
- Fully charged
doesnt mean full battery capacity
Most conventional chargers have an LED to indicate charge status. Red indicates
charging and green indicates charge complete. But what does charge complete
really mean? The charger is saying that it did the best it could given the
condition of the battery and it is done. However, the resulting battery capacity
could be far less than the original stated capacity for an old or defective
battery, yet the user has no way of knowing that with only an LED indication.
IMPRES chargers with displays provide the actual charge capacity of the battery,
so youll know exactly how much usage you will get from each battery.
- IMPRES charger
LED indicators give additional information
IMPRES chargers have additional LED indication capability to supply you with
even more information during a charge cycle. The alternating red/green LED
indicates batteries have fallen below a certain capacity threshold (typically
less than 60% of rated minimum capacity). An IMPRES battery exhibiting a red/green
indication is not defective it has simply reached a capacity level
that may limit its usage.
batteries are IMPRES compatible
Competitive battery manufacturers often claim to be IMPRES compatible.
While it may be true that some competitive batteries can be charged in IMPRES
chargers, there are still significant limitations and concerns. The communication
between an IMPRES battery and IMPRES charger that enables automatic reconditioning,
display of IMPRES data on display chargers and other IMPRES features is a
Motorola exclusive technology and will only occur with the combination of
IMPRES batteries and IMPRES chargers. Motorola does not test the charge compatibility
or safety of competitive batteries in IMPRES chargers.
