Battery Varta 4120 Longlife D Mono 1.5V — Primary zinc-carbon D size, 1.5V

Varta 4120 Longlife D Mono 1.5V is a primary zinc‑carbon D‑size battery intended for low‑ to medium‑drain devices. It provides standard 1.5V output in the familiar D cell format and is compatible with torches, portable radios, toys, and many household appliances that accept D batteries. The Longlife series focuses on delivering reliable, cost‑effective energy for both occasional and continuous use while maintaining simple drop‑in replacement and broad compatibility.

Advantages

The battery offers stable 1.5V voltage suitable for devices with moderate power demands. Its zinc‑carbon chemistry gives an economical option when long shelf life and cost efficiency are priorities. The D size provides higher capacity compared with smaller cells, reducing the frequency of replacements in devices like flashlights and battery‑powered radios. The cell is single‑use (primary) and ready to install without charging.

Suitable for

• Flashlights and portable lighting
• Children’s toys and electronic playthings
• Portable radios and small audio devices
• Household appliances that accept D‑size batteries (clocks, certain fans, etc.)

Key specifications

• Chemistry: zinc‑carbon (primary)
• Nominal voltage: 1.5 V
• Cell size: D (Mono)
• Intended use: low‑ to medium‑drain devices
• Storage: long shelf life when stored in a cool, dry place

How to use

Insert the battery into the device ensuring correct polarity according to the device markings. For best performance, replace all cells in multi‑cell devices at the same time with the same type and brand. Do not attempt to recharge this primary battery. After use, remove depleted cells from devices to avoid leakage and dispose of them according to local regulations for battery recycling or hazardous waste.

Recommendations

Store unused batteries in a cool, dry location away from direct heat and metal objects. For devices with continuous or high power demands, consider using higher‑capacity chemistries such as alkaline or rechargeable alternatives to extend run time. Keep batteries out of reach of children and follow the device manufacturer’s guidance for battery replacement.
