    internal resistance of battery

    Hi! I wonder how important is the internal resistance(ohm) of batteries? During changing, an ISDT charger shows resistance per cell. Some shows 10-15, and other shows 20-30. Could you tell beyond certain value could be dangerous or not efficient to use anymore, etc?

    battery safety question , based on internal resistance

    Hi, I have a question about battery safety , based on internal resistance. Have you checked internal resistances? I recently checked a couple of batteries and ISDT charger shows very different values per battery and cell. The video is saying if one of the cells shows different values, it’s...
