Battery Pack Charge Status - 3M Versaflo TR-830 User Instructions

• 3M™ 4-Station Battery Charger TR-944N: Insert the 3M™ Battery Charger TR-640 into one of the charging ports on the TR-944N and slide
back to lock into place. (Fig. 1b). (NOTE: the TR-941N power cord is not used with the TR-640, when the 4-station Charger is used.) Insert
the DC supply cord supplied with the kit into the 4-station base. Plug the power cord into an AC power source (100-240V), such as a wall
outlet. You may charge any combination of up to four 3M™ Battery Packs simultaneously.
NOTE: The 3M™ Battery Charger TR-640 and 3M™ 4-Station Battery Charger TR-944N do not use the same power supply. Use only the power
supply supplied with your charger kit.
4. Battery charging: Ensure the gold electrical contacts on the battery and charger are clean and free of debris. Insert the battery pack into the
3M™ Battery Charger Cradle TR-640 by sliding the back end of the battery pack in first. Set front end down into place (Fig. 2), charging will
begin. Refer to Fig. 4 and Table 1 in the "Specifications" section of these User Instructions for a list of charger LED displays and meanings, and
battery charge times.
5. Removal:
• Lift up on battery pack to remove from cradle.
• The 3M™ Battery Charger TR-640 can remain attached to the 3M™ 4-Station Battery Charger TR-944N if desired. To release the cradle
from base, press down on the oval release tab on the base, slide cradle forward and lift out. Be careful not to pinch fingers as the cradle
slides forward.

Battery Pack Connection to TR-800 series PAPR
Refer to the User Instructions for the 3M™ Versaflo™ Powered Air Purifying Respirator TR-800 assembly for specific directions on connecting and
disconnecting the battery pack from the PAPR unit. The fastener requires a 3/32 inch hex head hand tool. NOTE: Do not overtighten.

Battery Pack Charge Status

Battery pack charge status is indicated by pressing the indicator button on the top of the battery (Fig. 3). Number of bars illuminated indicates
approximate battery pack charge capacity (5 bars: 80-100%; 1 bar: less than 20%).
NOTE: As the battery pack ages, it will normally lose capacity. An older battery pack or one that has been exposed to temperature extremes may show
less than 5 bars after completing a charge cycle (i.e. after a charge cycle, only 4 bars light indicating 60-80% of original capacity is available).
The Lithium-ion battery packs do not require a learn cycle to calibrate or re-calibrate the battery pack charge indicator. However, it may take up to
three complete charge/discharge cycles for the battery to reach its maximum capacity and claimed run times.
