R20 (Carbon-Zinc): Cheaper but weaker, suited for low-drain devices.
Rechargeable Alternatives:
NiMH (1.2V, e.g., EN-95, ~3000–10,000 mAh)
Li-ion (3.7V, requires adapter for 1.5V devices).
Storage & Disposal Tips:
Store in a cool, dry place (avoid heat/humidity).
Remove batteries from unused devices to prevent leakage.
Recycle properly (many stores accept used alkaline batteries).
