Continuous discharge rating of a battery cell, in amps. The WINDBAR Ohm's law and battery calculators compare amp draw to CDR.
CDR is a cell safety label, not a vape setting. If amp draw approaches CDR, lower wattage, raise resistance, or use a cell with a higher continuous rating.
Also called: continuous discharge

CDR questions
How is CDR different from a battery mAh rating?
mAh estimates capacity; CDR is the continuous amp limit. High wattage on low ohms can hit CDR before you empty the mAh — check both in the battery calculator.
What if amp draw is close to CDR?
Add headroom: lower wattage, raise resistance, or use a cell with a higher continuous rating. Pulse ratings are not the same as CDR.
