FAQs about the Varta Longlife 4R25 battery

For which devices is this battery mainly intended?

This battery is ideal for devices with low, but long-lasting energy requirements. These include, above all, construction site warning lights, flashing lights, large camping lanterns and electric fencing devices.

What is the difference to an alkaline version (4LR25)?

The main difference is in the cell chemistry. The zinc-carbon version (4R25) is the more economical choice and perfect for devices with low, constant power consumption. The alkaline version (4LR25) is more expensive, but offers higher capacity and performance. It is better suited for devices with higher power consumption (e.g. bright halogen hand lamps) and for use at very low temperatures.

What is the advantage of the spring contacts?

The spring contacts enable very easy, tool-free and quick installation. They provide a secure and firm fit of the lamp head or connection cables and ensure a reliable power connection that is insensitive to vibrations.

Is this battery rechargeable?

No, the Varta Longlife 430 is a primary battery and cannot be recharged. Attempts to charge are dangerous and can cause the battery to leak or burst.

How should this battery be disposed of?

Batteries must not be disposed of in household waste. Please take the empty battery to the appropriate collection points in shops or municipal recycling centres to ensure environmentally friendly recycling.
