It is the better choice for all devices, especially those with higher power consumption (e.g. bright light bulbs). The zinc-carbon battery (3R12) is an older, more cost-effective technology for very simple applications.

For which devices is this battery best suited?

It is ideal for devices that require a 4.5 volt power source in this classic flat format. These include large torches, camping lanterns and a variety of experimental and electronic kits for schools and hobby users.

How can I recognise the positive and negative terminals?

The poles are clearly labelled on the battery. The positive terminal (+) is the short, wide contact tab, while the negative terminal (-) is the long, narrower contact tab.
