Duracell Ultra 123 3V Lithium Battery x2 - DL123B2

These batteries are commonly used in high-drain devices such as digital cameras, tactical flashlights, home security system sensors, and some portable medical equipment due to their stable voltage and long-lasting power.

No, Duracell Ultra Lithium CR123A batteries are primary (non-rechargeable) cells. Attempting to recharge them can be dangerous.

Duracell Ultra Lithium CR123A batteries typically have a long shelf life, often up to 10 years when stored properly in their original packaging at room temperature. The packaging usually provides a 'best by' date.

No, `CR123A` batteries are not interchangeable with AA or AAA batteries. They have a different voltage (3V vs. 1.5V) and different physical dimensions. Always use the specific battery type recommended by your device manufacturer.

The standard dimensions for a `CR123A` battery are approximately 17.0mm in diameter and 34.5mm in length.

Lithium batteries should not be thrown in regular household trash. Please recycle them at designated battery recycling centers or collection points, which can often be found at electronics stores or municipal waste facilities. Check your local regulations for proper disposal.

First, double-check that the batteries are inserted with the correct polarity (`+` to `+`, `-` to `-`). If correct, try replacing with a fresh set of batteries, as even new batteries can occasionally be faulty. Ensure the battery compartment is clean and free of corrosion.

Verify that your device is specifically designed for `CR123A` batteries and is not drawing excessive power. Check for any settings in your device that might be consuming more power (e.g., high brightness, constant connectivity). Extreme operating temperatures (very cold or very hot) can also impact battery life.

Confirm that your device requires `CR123A` batteries. While `CR123A` has many equivalent names, its physical dimensions (17.0mm diameter, 34.5mm length) are standard. If your device specifies a different battery type or size, these batteries will not be compatible.

This could indicate low battery charge or poor contact. Replace the batteries with a fresh pair. Also, inspect the battery terminals in your device for any dirt or corrosion and clean them carefully if necessary.
