Overview of Flashlight Battery Types
At OBO Bright Flashlight Vendor, we understand that selecting the right battery is crucial for reliable lighting. Flashlights use several battery types, each with unique characteristics:
Quick Reference Battery Comparison Table
| Battery Type | Nominal Voltage | Capacity Range (mAh) | Typical Runtime (hours) |
|---|---|---|---|
| Alkaline AA | 1.5V | 1500 – 3000 | 1 – 10 |
| NiMH AA | 1.2V | 800 – 2800 | 2 – 8 |
| Lithium CR123A | 3V | 1300 – 1700 | 1.5 – 5 |
| Li-ion 18650 | 3.7V | 2000 – 3500 | 3 – 20 |
| Li-ion 21700 | 3.7V | 4000 – 5000 | 6 – 24 |
💡 Pro Tip: Not all batteries are created equal – choose wisely for optimal performance!

Comparing Battery Chemistries: Pros and Cons
| Battery Type | Pros | Cons |
|---|---|---|
| Alkaline | Affordable, widely available | Lower capacity, non-rechargeable |
| NiMH | Rechargeable, eco-friendly | Self-discharge over time |
| Lithium | High energy density, lightweight | More expensive |
| Li-ion | Long lifespan, high capacity | Requires specific chargers |
How Battery Capacity Impacts Flashlight Runtime
Battery capacity directly influences how long your flashlight will operate. For example:
- An 18650 Li-ion battery with 3500 mAh can last significantly longer than an Alkaline AA rated at 2500 mAh
- Higher capacity means extended runtime, especially in high-drain situations
- Lower brightness settings can dramatically extend battery life
