ANSMANN Alkaline battery 3LR12A (1.5V) – 3LR12 size, single cell

ANSMANN Alkaline battery 3LR12A (1.5V) is a single-cell power source in the 3LR12 size that provides a steady 1.5-volt output for devices designed to accept this format. This alkaline cell is intended for equipment such as portable lamps, radios, measurement instruments and other battery-operated tools. The battery is manufactured to offer stable voltage during discharge and an extended storage life when kept unused.

Advantages

The battery delivers consistent 1.5V output for reliable device operation and is made with alkaline chemistry for improved energy density compared with standard zinc-carbon cells. It is designed for long shelf life and low self-discharge, which helps retain capacity during storage. The single-cell format makes replacement straightforward in devices requiring the 3LR12 size, and the construction supports common ambient temperature ranges encountered in everyday and professional use.

Suitable for

• Handheld torches and portable lighting
• Battery-powered radios and communication devices
• Measurement tools such as multimeters and environmental sensors
• Portable medical devices and monitoring equipment that accept 3LR12 cells
• Other consumer and professional devices specifying 3LR12 alkaline cells

Key specifications

• Cell type: Alkaline single cell
• Nominal voltage: 1.5 V
• Format/size: 3LR12 (also known as 3R12/4.5V-compatible battery housing alternative size)
• Typical applications: low- to medium-drain portable devices
• Storage characteristics: low self-discharge for extended shelf life

How to use

Install the ANSMANN 3LR12A alkaline cell into the device following the polarity markings indicated in the battery compartment. Ensure contacts are clean and free of corrosion before insertion. Replace the cell when device performance decreases or when the device indicates low battery. Dispose of used batteries according to local regulations for battery recycling and hazardous waste.

Usage recommendations

For optimal results, store the battery in a cool, dry place away from direct sunlight and heat sources. Avoid mixing new and used batteries or different chemistries in the same device to prevent leakage or reduced performance. Check device requirements to confirm compatibility with the 3LR12 size and 1.5V nominal voltage prior to use.
