| AAA | 1.5V/1.2V | 600mAh – 1200mAh |
How do voltage levels differ among these batteries?
Voltage levels are one of the most significant differences between these battery types:
- 14500 Battery: Has a nominal voltage of 3.7V, making it suitable for high-drain devices that require more power.
- AA Battery: Provides approximately 1.5V for alkaline versions and 1.2V for NiMH versions.
- AAA Battery: Similar to AA, it offers about 1.5V for alkaline and 1.2V for NiMH.
This difference in voltage affects compatibility with devices; using a battery with an incorrect voltage can lead to poor performance or damage.Chart: Voltage Levels Comparison
| Battery Type | Nominal Voltage |
|---|---|
| 14500 | 3.7V |
| AA | 1.5V (alkaline) / 1.2V (NiMH) |
| AAA | 1.5V (alkaline) / 1.2V (NiMH) |
What are the capacity differences between 14500, AA, and AAA batteries?
Capacity indicates how much energy a battery can store and deliver over time:
- 14500 Batteries: Typically have lower capacities compared to AA batteries but provide higher energy density due to their lithium chemistry.
- AA Batteries: Generally offer higher capacities ranging from 1000mAh to over 3000mAh, making them ideal for devices requiring long runtimes.
- AAA Batteries: Offer lower capacities than AA batteries, generally between 600mAh and 1200mAh, which limits their use in high-drain applications.
Understanding these differences helps consumers choose the right battery based on their energy needs.Chart: Capacity Comparison
| Battery Type | Capacity Range |
|---|---|
| 14500 | 600mAh – 800mAh |
| AA | 1000mAh – 3000mAh |
| AAA | 600mAh – 1200mAh |
How do the dimensions of these batteries compare?
The physical size of each battery type affects compatibility with devices:
- 14500 Battery: Measures approximately 14mm in diameter and 50mm in length, similar to an AA battery.
- AA Battery: Standard size is about 14mm in diameter and 50mm in length.
- AAA Battery: Smaller than both at approximately 10.5mm in diameter and 44.5mm in length, making it suitable for compact devices.
The size difference impacts which devices can utilize each type of battery effectively.Chart: Size Comparison
| Battery Type | Diameter (mm) | Length (mm) |
|---|---|---|
| 14500 | 14 | 50 |
| AA | 14 | 50 |
| AAA | ~10.5 | ~44.5 |
What are the advantages and disadvantages of each battery type?
