It’s not dangerous. It just degrades the batteries.
Comment on My charger wouldn't fit D-batteries, so I made an adapter. Printables link, with F3D file, inside
IMALlama@lemmy.world 1 year agoThis is true, but at the default 500 mAh charge rate it seems unlikely that much heat will be generated? Worst case of 100% of input voltage getting converted to heat would be 700mW or so of energy needing to get dissipated per cell.

If “10,000 mAh” (if they’re half that I’ll be happy) batteries are heating while charging at 500mA odds are they’re not in great shape to begin with.

Yeah, the big cells can handle that just fine. The charger would overheat first unless a cell is shorted, which only possible with NiMH/NiCd if the charger malfunctions or the battery is physically damaged.

The charger circuitry should be designed to avoid that issue entirely.
