The lifespan of both brands varies based on type:

1. Alkaline Batteries: Generally last between 5 to 10 years when stored properly.
2. Lithium Batteries: Can last up to 10 years or more due to lower self-discharge rates.
3. Rechargeable NiMH: Typically last around 500 charge cycles before significant capacity loss occurs.

What Are the Advantages of Each Brand?

Duracell is known for reliability and performance in high-drain applications, making it ideal for demanding devices. Energizer often provides better value for low-drain uses and is recognized for its commitment to sustainability through recycling programs.

Both brands have unique advantages:

1. Duracell:
   • Known for reliability in high-drain applications.
   • Offers a wide range of products including specialized batteries.
2. Energizer:
   • Often provides better performance in low-drain scenarios.
   • Has a reputation for being environmentally friendly with recycling programs.

Replacement Options for Lithium-Ion Batteries

For those looking for alternatives or replacements, consider:

1. Nickel-Metal Hydride (NiMH): Offers decent performance but generally has lower energy density than lithium-ion.
2. Lead-Acid Batteries: More affordable but heavier and less efficient compared to lithium-ion options.
3. Solid-State Batteries: Emerging technology with potential advantages in safety and energy density.
