User manual NOVAK MILLENNIUM

[. . . ] · Excessive charging current can damage batteries­­Maximum charging rates for nickel-cadmium and nickel-metal hydride can be obtained from battery maker. · Never exceed 15 volts DC input power source to power the Millennium. · Gases from a lead-acid battery may ignite if sparks occur when connecting or disconnecting the Millennium's alligator clips­­Using a lead-acid battery as a power source may generate hydrogen gas and should only be used in a well ventilated area. Avoid open flames and sparks which may ignite battery gases. PLEASE FOLLOW ALL INSTRUCTIONS CAREFULLY WELCOME TO THE NEW MILLENNIUM The Novak Millennium is a complete battery management system designed to get the most performance out of your batteries. [. . . ] Solder the black alligator clip to the wire from the negative (­) lower pin. From the Start screen, push the up (C) button three times to go to the Volt Threshold option screen, or once more from the Button Tone screen. The Volt Threshold value entered is the drop in millivolts that the Millennium looks for to determine that the battery pack has peaked. This is adjustable from 4 to 20 mV/cell (refer to Tips & Rec. To adjust, push the ENTER button from the Volt Threshold option screen. You can now use the down (B) and up (C) buttons to change the value. DETAILED CHARGE HISTORY SELECT MENU CB View Charge Info RECOMMENDED SETTINGS (Ni-CD & Ni-MH) From the Start screen, push the up (C) button four times to go to the View Charge Info option screen, or once more from the Volt Threshold screen. Remember that these screens are on a loop, and you can go either direction to get back to a desired option screen. The View Charge Info option gives you detailed information about the last battery pack that was charged. This information can prove helpful in comparing battery packs, and also tracking the performance of your packs. To view the charge history, push the ENTER button from the View Charge Info option screen. If the Millennium has never been used, or it has been reset to factory defaults, all values will be zero. The display shows the battery's peak voltage, 9. 95V 1653sec the time in seconds to charge the pack, the 2185mAh 81316J battery pack's capacity in milliamp hours, and the pack's energy measured in joules. The calculations used are: Capacity (mAh) = {Charge Current (milliamps)} x {Charge Time (hours)} Energy (J) = {Charge Current} x {Charge Time} x {Average Charge Voltage} CHARGE MODE SELECTION SELECT MENU CB Charge Mode From the Start screen, push the down (B) button once, or the up (C) button five times to go to the Charge Mode option screen. Push the ENTER button from the Charge Mode option screen. You can now use the down (B) and up (C) buttons to change the Millennium's method of charging. The choices are as follows: SELECT MENU CB Charge Mode T CHARGE MODE CB NiCd Rev Pulse T Cells Amps Pulse 6 4. 3 8ms DISCHARGING Ni-Cd To maintain capacity, discharge every charge cycle with 30 ohm/10 watt resistor across terminals. Remove when resistor cools to room temp. Ni-MH Do not deep-discharge (No discharge trays, resistors, or light bulbs). LINEAR CHARGING MODE Ni-Cd Charge at 3. 5-4. 5 amps for Sub-C & D cells, and 0. 5-1. 0 amp for AA's. Battery makers specify the charge current at no more than 2. 5 times the capacity (2. 5 x 2000mAh = 5. 0A) & twice capacity for D cells. Ni-MH Charge Sub-C Ni-MH cells at 4. 0-5. 5 amps and trickle charge OFF. REVERSE-PULSE CHARGING MODE Ni-Cd A rev. pulse duration of 12ms will help enhance run times & increase average discharge voltage by lowering battery's internal resistance. [. . . ] During the charge, the LCD cycles through three screens of charge information, including: {charge time & pack voltage}, {# of cells & delta-peak value}, and {charge mode, charge current, charge time, & pack voltage}. At the end of charge, the Millennium will cycle between the charge history screen and a Charge Complete screen accompanied by an audible alert. PRODUCT WARRANTY Novak Electronics, Inc. guarantees the Millennium to be free from defects in materials and workmanship for a period of 120 days from original date of purchase (verified by dated, itemized sales receipt). Warranty does not cover incorrect installation, components worn by use or excessive force, exceeding the recommended input voltage, damage resulting from charging more than the recommended number of cells, or from improper connection or charging of receiver battery packs or enhanced-voltage batteries, any splices to the output wires, damage from disassembling the case, tampering with the internal electronics, allowing water, moisture, or any other foreign materials to enter charger or get onto the PC board.
