A battery date code sticker indicates D6. What does this mean?

1. The date it was shipped from the factory was December 2006.

2. The date it was shipped from the factory was April 2006.

3. The battery expires in December 2002.

4. It was built the second day of the week (Tuesday).

The correct answer is: The date it was shipped from the factory was April 2006.

The code found on the battery date sticker, such as D6, typically uses a letter followed by a number to signify a specific date format. In this instance, 'D' represents April, as the first letter of the alphabet typically corresponds to January (A), followed by February (B), March (C), and then April (D). The number '6' indicates that it was manufactured in the year 2006. Therefore, when interpreting the code, it indicates that the battery was shipped from the factory in April 2006. This understanding is particularly useful when determining the age of a battery, which can impact its performance and lifespan. Knowing the manufacturing date helps consumers assess how long the battery has been sitting on the shelf, which is critical for making an informed purchasing decision.
