When purchasing batteries, there are several important factors to consider:

A. Size: CR2032 is a small, lithium-based battery with a 3V high density and high power output. Batteries come in various sizes, and it is crucial to choose the correct size. The digit numbers indicate the battery size, so ensure the four digits match the original.

B. Safety: Batteries have a 3V high voltage and high capacity, despite their small size. Reputable brands will have their name printed on the package and the battery itself. It is essential to buy high-quality batteries from trusted brands or manufacturers to avoid potential leakage or explosion hazards.

C. Stability: Different technologies and materials affect the battery's stability. Batteries with nickel-plated shells, a rare and more expensive metal, can achieve up to a 5-year shelf life without leakage, as they are better sealed and more stable.

D. Durability: Good batteries should last as long as possible. Durability is related to the battery's capacity, which is marked as XXXmAh on the packaging or description. Higher capacity typically means longer-lasting batteries.

E. Freshness: Lithium batteries are single-use, and reputable brands will clearly mark the manufacturing date on the batteries to help consumers identify and avoid old, low-power stocks.

F. Mercury-free: Responsible manufacturers use mercury-free materials to protect the environment, making the batteries safer, more stable, more durable, more precise, and more reliable.
