1. What Are Primary Batteries?

Primary batteries are single-use batteries that cannot be recharged. They convert chemical energy to electrical energy through irreversible chemical reactions.

2. Common Primary Battery Types

The calculator shows information about these primary battery types:

• Zinc-Carbon
• Alkaline
• Lithium
• Mercury
• Silver Oxide

3. Characteristics of Primary Batteries

5. Frequently Asked Questions (FAQ)

Q1: Why use primary batteries instead of rechargeable?
A: Primary batteries have higher energy density, longer shelf life, and are often cheaper for infrequently used devices.

Q2: Are all primary batteries 1.5V?
A: No, voltages vary. Lithium batteries are typically 3V, while silver oxide is 1.55V.

Q3: Which type has the longest shelf life?
A: Lithium primary batteries can last 10-15 years, making them ideal for emergency devices.

Q4: Are mercury batteries still available?
A: Most countries have banned mercury batteries due to environmental concerns.

Q5: What's the most common primary battery today?
A: Alkaline batteries dominate the market due to their balance of cost and performance.
