Dollar Tree has 3 different types of alkaline batteries. All cost $1 per package, but they come 2, 3, or 4 to a package - effectively making the 2-pack cost double the 4-pack. Are the 2-pack batteries worth the extra cost?

tl/dr: No.

Battery testers used:
LiitoKala Lii-500 Smart Charger, around $45
ZB2L3 Battery Discharge Tester, around $3
