Operating Instructions for the LG1485 Battery Charger
Foreword
Dear Customer,
Please read these operating instructions carefully before you use the LG1485 Battery Charger.
Pay particular attention to the safety notices on the following pages.
Keep these instructions for future reference and pass the documentation on to any future owners.
Brief Description and Functionality
The LG1485 Battery Charger is a charger and testing device for up to four rechargeable batteries, featuring an integrated
System Management Bus (SMBus).
The device can be used to charge any combination of two-cell (7.2 V) and three-cell (10.8 V) rechargeable lithium ion
batteries.
The battery charger communicates with the batteries via the SMBus. When a battery is inserted into the charger slot, the battery
charger automatically checks whether the battery only needs to be charged or requires a full testing cycle (conditioning).
To measure and optimize battery capacity and to recalibrate the SMBus system, the device alternates between charge and
discharge cycles during the full testing cycle. Once the testing cycle is complete, the battery is ready for use. The battery
status is shown by the testing LED (see the table on the following page).
The testing cycle can be started and stopped individually for each battery by pressing the corresponding button.

Commissioning the Device
• Before connecting the device to the power supply, check that the voltage indicated on the system label matches the
mains voltage in your building. Connecting the device to an improper power supply may cause severe damage to the
device and personal injury.
• Do not insert any objects such as metal wires or tools into the inlet or outlet vents. Caution: This may lead to electric
shocks.
• If you do not use the device for an extended period of time, we would recommend that you disconnect the mains plug.
• The use of accessories and replacement parts that are not recommended by the manufacturer may cause damage to
the device and injury.
• Use only the rechargeable lithium-ion batteries listed below with the LG1485 Battery Charger:
Philips P/N: M4605A (3S3P)

Instructions for Use for the LG1485 Battery Charger
Charging the Battery
• Insert the rechargeable battery into any free charger slot. Do not use force when inserting the battery.
• The device will detect the battery type and will switch automatically to the required charging mode.
• The device will detect whether the battery requires a testing cycle (conditioning).
• If the testing LED flashes yellow, a testing cycle is required.
• To stop or start the test manually, press the button.
• If no testing cycle is required, the battery will be charged in standard mode. While charging is in progress, the charging
LED will flash yellow.
• When the charging LED turns green (and the testing LED is off), the battery is fully charged and ready for use.
• Remove the fully charged battery from the battery charger.
Testing Cycle (Conditioning)
• If a testing cycle was started, either manually or automatically, the testing LED will flash yellow until the battery is fully
discharged. The test consists of three steps:
 Step 1: First battery charge cycle, if the battery is not yet fully charged.
 Step 2: Battery discharge cycle.
 Step 3: Second battery charge cycle.
• The measured capacity is then displayed by the testing LED lighting up permanently
(green = good, yellow = reduced capacity, or red = replace the battery).
• When the charging LED turns green, the charging process is complete. The LED displaying the measured capacity will
continue to light up.
• Remove the fully charged battery from the battery charger.
• When conditioning, up to two batteries can be discharged at the same time.
Battery Errors
• If the battery charger detects a battery error, both LEDs will flash red. To clear the error display, remove the battery.
• Never use a faulty battery.

It is recommended to clean the material in both air filters regularly. Depending on the frequency of use and the ambient
conditions (dust, etc.), the air filter material should be cleaned or replaced every 6–24 months. You can clean or replace the
air filter material yourself.
• Disconnect the mains plug from the socket.
• The air filters are on the right and left sides of the device.
• Remove the two screws and the filter cover.
• Remove the air filter material and shake it out or replace it.
• Reinsert the air filter material, the cover and the screws.

connect the LG 1485 to an external PC via a USB cable (type B USB 1.0/2.0 connector).
For more information about firmware updates, see the description for the relevant software package, which can be provided
if required.
Safety Notice for Repair and Service
Repairs may only be carried out by qualified professionals working for the manufacturer. Never try to repair the device
yourself!
Caution
The device must be disconnected from the mains power supply before it is opened.
The intermediate circuit capacitor in the inbuilt switch-mode power supply may still contain a dangerous electrical charge
over one hour after the device is disconnected from the mains.
Test operation may only be performed by trained professionals using a safety isolation transformer.
When the fans are running, the rotor blades inside the device present a risk of injury.
