What the AI looks for in D Batteries
- True D vs shelled cells
- Check whether a rechargeable D is full-size or an AA-sized cell inside a sleeve Shelled D cells give a fraction of true D runtime.
- Emergency kits
- Store cells outside the device and check expiry dates Leaks in stored flashlights are the most common failure.
Brands that matter
- Energizer: Max alkaline D.
- Duracell: Coppertop alkaline D.
- Rayovac: Value alkaline D.
- Panasonic: Alkaline and eneloop D options.
What to avoid
- Rechargeable D cells with capacity no higher than an AA
- Leaving D cells installed in stored flashlights
