User manual NOVAK BATTERY CARE SHEET

[. . . ] Ni-MH BATTERY CARE SHEET Basic Ni-MH Battery Care Ni-MH packs should be charged at a maximum rate of 4. 5-5. 0 amps until warm (not hot), and used as soon as they are done charging for optimum performance. If the pack sits for more than 10 minutes you will not get full performance. [. . . ] We highly recommend using an equalizing discharge tray that has a userselectable cut-off voltage like the Novak Smart Tray (#4500). The Smart Tray also features individual status LEDs to let you know when each cell has completely discharged. Using the Novak Smart Tray before each charge will give you the best possible performance from your batteries. Packs That Continue To False-Peak Some customers may experience false-peaks with sport packs, receiver packs, or packs that have been previously abused or are very old. This can be due to lower quality cells or the construction of the packs. The Ni-MH cells in these packs are often never discharged properly so the cells can be very problematic. The first thing that should be done for these packs is to discharge them and let them cool completely. If it the pack continues to false-peak you may need to set the charger up differently. The Ni-Cd Linear charge mode found in the Novak Millennium Pro and the Novak Ionic chargers uses voltage threshold to determine the battery's peak. For a problematic Ni-MH pack, this may be the only way to get it to take a full charge. Set the charger at your desired current with the voltage threshold set to 4 mV/cell. If false-peaking continues, increase the voltage threshold by 2 mV/cell. If you reach this setting and repeated false-peaking continues, you can activate the Trickle charge in the Millennium Pro by turning this feature on in the Edit Charge mode. If a false-peak occurs now, the trickle mode will continue to charge the pack at a very slow rate. Let the trickle charge continue for about 10 minutes, then restart the normal charge cycle. [. . . ] When you use the packs again, discharge them to 0. 9 volts per cell and let them cool completely before charging. The discharge before charging will give the best performance and should help prevent false-peaking. www. teamnovak. com www. teamnovak. com AD-NIMH-1 · 2/2004 [. . . ]
