How to select the right 4.5V battery
Before ordering, check the marking on your old battery or in the device manual. If it says 3LR12, 4.5V, 4.5 volt or uses the same flat rectangular shape with two strip terminals, the products in this category are the correct match. The Varta Longlife Power 4.5V battery is a strong option for devices that need reliable energy over longer operating periods.
For best results, always replace the battery with the same voltage and format. Do not try to combine multiple smaller batteries unless the device manufacturer specifically allows it.
Storage and usage tips
Keep your 3LR12 alkaline battery in a cool, dry place away from direct sunlight and moisture. Remove it from devices that will not be used for a long time, especially lamps, toys and seasonal equipment. This helps protect the device contacts and preserves battery performance.
Tip: If your device has weak light, slow operation or intermittent power, replacing the old cell with a fresh 4.5V 3LR12 alkaline battery is often the fastest solution.
