![]() ![]() The charger is a bit slow to start, because it is waiting some seconds for user input. With the compact size the temperature is a bit high at full charge current. With four cells the maximum charge current is 700mA and it is handled fine (Remember my temperature sensor is not mounted on the same cell as the V/A sensors).ĭisplay shows 1944mAh, 2091mAh, 2032mAh, 2091mAh in 3:06, 3:21, 3:15, 3:20 The AAA is no surprise, also perfectly charged. The charger needs some time to reconize a full cell, but it is smart enough to do it at low current.įor some reason the 1A charge current is slightly lower here, but the cell is perfectly charged. The charger is rated to do 1A, but it is at the limit. With 400mA the current is high enough to see the increased temperature when the cell is full. The same with the 3 other slots, all have nice terminations.ĭisplay shows 2049mAh, 2020mA, 2030mA in 3:28, 3:18, 3:23Įven at 200mA current the charger do a nice termination. This charger is smart enough to terminate correctly even at the lower current. The charger reduces current when the battery is nearly finished, this keeps the heat down, but makes it more difficult to terminate correctly. The 1000mA is only available in slot #1 and #4 and only when slot #2 and #3 is empty. The charge mode can select between 200, 300, 400, 500, 7, default is 400mA. Charge will restart charging after power loss, or battery insertion.When not powered it will discharge the battery with 0.4mA. ![]() Notice the metal strips touching the side of the battery, this is probably connected to a temperature sensor. The charger uses a AA/AAA two level slot. The CURRENT button will step between the possible currents. The MODE button is used to select mode for one or for all slots, it is also possible to change mode later on. When working the display looks like this, the DISPLAY button can be used to select what to show (v/h/mA/mAh). ![]() Selftest during powerup shows all the text on the display. When powered on the charger briefly shows the version number of the software. The charger has a barrel connector for 12V power input.Īs all analyzing charger it has a display and a couple of buttons. The box contains the charger, a power supply and a manual. This is a compact 4 channel analyzing charger from Opus. Review of Charger Opus BT-C700 Charger Opus BT-C700 ![]()
