Cell battery Varta 146202 4.5V Alkali-Mangan — 4.5V micro battery

Varta 146202 is a 4.5V alkaline‑manganese micro battery designed to deliver a stable fixed voltage for small electronic devices and replacement applications. The cell offers reliable performance where a compact, single‑cell 4.5V supply is required, suitable for household instruments, portable electronics and legacy devices that specify a 4.5V battery format.

Advantages

The alkaline‑manganese chemistry provides steady voltage output and a long shelf life compared with some primary cell types. The compact micro size and durable casing make the cell easy to install in confined compartments and resistant to typical handling during replacement. Its consistent nominal voltage simplifies device compatibility when a 4.5V fixed supply is specified.

Suitable for

• Portable measuring instruments and meters
• Small household appliances and toys that require 4.5V
• Replacement in legacy equipment designed for a single 4.5V cell
• Battery compartments with constrained space where a micro cell is needed

Key specifications

• Chemistry: alkaline‑manganese
• Nominal voltage: 4.5 V
• Form factor: single micro cell (compact cylindrical design)
• Typical use: primary (non‑rechargeable) single‑use cell
• Operating temperature range: suitable for normal indoor use conditions

How to use

Install the cell according to the device manufacturer’s instructions, observing the correct polarity markings in the battery compartment. Ensure contacts are clean and free from corrosion before insertion. Do not attempt to recharge the cell; it is intended for single‑use only. After depletion, dispose of the battery in accordance with local regulations for household batteries and recycling programs.

Recommendations

Store unused cells in a cool, dry place away from direct heat and moisture. Replace batteries in matched sets when multiple cells are used together and check device contacts for secure connection to maintain reliable performance.
