How to tell if a battery is lithium or alkaline?

Here's a comparison between the Energizer Battery Company E91 (alkaline) and lithium batteries:

E91 Alkaline Battery

• Chemistry: Alkaline Manganese Dioxide
• Nominal Voltage: 1.5V
• Nominal Capacity: 2850mAh
• Shelf Life: Up to 10 years
• Alkaline battery operating temperature: -18°C to 55°C
• Dimensions: 14.5mm x 50.5mm
• Weight: 15g
• Features: Cost-effective, reliable performance; stable discharge; high-drain pulse discharge
• Compliance: RoHS

Lithium Battery (CR2032 for example)

• Chemistry: Lithium Manganese Dioxide (Li-MnO2)
• Nominal Voltage: 3V
• Nominal Capacity: Typically around 220-250mAh for CR2032
• Shelf Life: Up to 10 years
• Operating Temperature: -30°C to 60°C
• Dimensions: 20mm x 3.2mm (diameter x height)
• Weight: Around 3.1g
• Features: Higher energy density; longer shelf life; lighter weight
• Compliance: RoHS

Comparison

• Voltage: Lithium batteries have a higher nominal voltage (3V) compared to alkaline batteries (1.5V).
• Capacity: Alkaline batteries generally have higher nominal capacities compared to lithium batteries, but the actual capacity can vary based on the specific battery model.
• Temperature Range: When compared to alkaline batteries, lithium batteries usually have a larger operational temperature range.
• Dimensions and Weight: Lithium batteries are typically smaller and lighter than alkaline batteries, which can be advantageous in certain applications.
• Cost: Alkaline batteries are generally more cost-effective than lithium batteries, but lithium batteries often offer better performance in terms of energy density and shelf life.

Overall, the choice between an alkaline battery like the E91 and a lithium battery depends on the specific requirements of the application, such as voltage, capacity, temperature range, size, weight, and cost.

Which is better lithium ion AA or alkaline battery?

A number of aspects are taken into consideration when comparing lithium-ion (Li-ion) with alkaline batteries, including cost, environmental impact, and performance. Here's a detailed comparison between the two:

1. Performance:

   • - Capacity: Li-ion batteries typically have a higher energy density and thus a higher capacity than alkaline batteries. This implies that in high-drain devices, they can hold more energy and operate for longer.
   • - Voltage: Alkaline batteries gradually lose voltage during their discharge cycle, whereas Li-ion batteries have a rather steady voltage throughout. This can be advantageous for devices that require a consistent power supply.
   • - Temperature: Li-ion batteries perform better at low temperatures compared to alkaline batteries, which can be beneficial for outdoor use or in cold environments.
   • 
     

2. Price:

   • - Initial cost: Li-ion batteries are usually more expensive initially than alkaline batteries.
   • - Long-term cost: However, Li-ion batteries can be recharged hundreds of times, making them more cost-effective in the long run compared to alkaline batteries, which are disposable.
   • 
     

3. Environmental Impact:

   • - Disposal: Alkaline batteries are considered single-use and must be disposed of properly to minimize environmental impact. Li-ion batteries generate less waste and can be recharged.
   • - Toxicity: Li-ion batteries are thought to be less hazardous to the environment than alkaline batteries, which contain hazardous substances including cadmium and mercury.
   • 
     

4. Applicability to Electronics:

   • - Devices with a high drain: Li-ion batteries work well with devices with a high drain, such as digital cameras, where longevity and performance are essential.
   • - Low-drain devices: Alkaline batteries may work better in low-drain devices, such as clocks and remote controls, when performance and replacement costs are not as important considerations.
   • 
     

5. Conclusion:

   • - Li-ion batteries are generally better for high-performance devices that require long battery life, frequent use, and high energy demands.
   • - Low-drain devices or circumstances where initial cost is a major consideration are better suited for alkaline batteries.

E91 vs Lithium Batteries Conclusion

The choice between Li-ion AA batteries and alkaline batteries depends on the specific requirements of your devices. If you prioritize performance, longevity, and environmental sustainability, Li-ion batteries are the better option. However, if upfront cost and convenience are more important, alkaline batteries may be the more suitable choice.
