Lithium AA batteries have a higher energy density compared to alkaline and rechargeable options, allowing them to store more energy in a smaller size.
| Battery Type | Energy Density (Wh/kg) |
|---|---|
| Lithium AA | 150-200 |
| Alkaline AA | 100-120 |
| NiMH Rechargeable | 60-100 |
2. Shelf Life
Lithium batteries excel in shelf life, making them ideal for emergency kits and devices that are not frequently used.
| Battery Type | Shelf Life (Years) |
|---|---|
| Lithium AA | 10+ |
| Alkaline AA | 5-7 |
| NiMH Rechargeable | 3-5 |
3. Performance in High-Drain Devices
Lithium AA batteries maintain consistent voltage output even under heavy load, making them suitable for high-drain devices like digital cameras.
| Battery Type | Voltage Output (V) | Performance in High-Drain Devices |
|---|---|---|
| Lithium AA | 3.7 | Excellent |
| Alkaline AA | 1.5 | Moderate |
| NiMH Rechargeable | 1.2 | Good |
Relation to Lithium LiFePO4 Batteries
Lithium LiFePO4 (LFP) batteries are a specific type of lithium battery known for their safety and thermal stability. While lithium AA batteries are designed for smaller devices, LFP batteries are used in larger applications such as electric vehicles and renewable energy systems. Both types share the advantages of lithium technology, including longevity and efficiency.For clients or importers with wholesale or OEM requirements, we recommend our LiFePO4 Batteries, which provide superior performance and reliability across various applications.
