FAQs about the Varta V28PXA specialty battery

What do the designations 4LR44, PX28A or A544 mean?

These are alternative designations for the same battery type from other manufacturers or according to different standards. The Varta V28PXA is compatible with all batteries bearing any of these designations.

Can I replace this battery with a silver oxide version (4SR44)?

Yes, this is possible in many devices. A silver oxide battery (4SR44) offers a more stable voltage profile, which can result in more accurate exposure metering in some cameras. For most applications, however, the alkaline version V28PXA offers a better price-performance ratio.

Why does this battery have a voltage of 6 V?

Inside the V28PXA are four small 1.5 V alkaline button cells (LR44), which are connected in series. The series connection adds up the individual voltages (4 x 1.5 V = 6 V). This voltage was and is required for many analogue camera systems and other special electronics.

How should this battery be disposed of?

Specialty batteries must not be disposed of with household waste. Please take the empty battery to the designated collection points in retailers or municipal recycling centres to ensure environmentally sound recycling.
