BBC Radio 4 - Sliced Bread, Batteries

Do more expensive AA batteries really last longer?

Do AA batteries from brands that promise to last longer and cost extra, really do so?

In the run up to Christmas, many parents will be checking on their battery supplies ahead of Santa bringing gifts that require them. But do branded batteries, that promise more power and longer life at a higher price point, really deliver it?

Listener Peter got in touch asking just that, as well as whether batteries have an expiry date? 

Greg Foot recruits some year 7 pupils and their teacher to help him perform a test to find out, and speaks to one of the country’s leading scientists about what gives a battery more power, or helps it store more energy. 

You can also hear more about the difference between single use, and rechargeable batteries in our longer podcast episode on BBC Sounds. 

This series, we’re testing and investigating your suggested wonder-products. If you’ve seen an ad, trend or fad and wonder if there’s any evidence to back up a claim, drop us an email to sliced.bread@bbc.co.uk or you can send us a voice note to our new WhatsApp number: 07543 306807.

While Sliced Bread takes a break, we serve up... Toast.

While Sliced Bread takes a break, we serve up... Toast. Sean Farrington examines the spectacular failures of wonder products and businesses which had promised so much.

While Sliced Bread takes a break we serve up... Toast. A study of the spectacular failures of brands which had promised so much to consumers.    

In each episode, the presenter and BBC business journalist, Sean Farrington, examines one big idea. What did it promise? Why did people back it? Why did they get burnt?  

Some of the world's most successful businesses have also brought us some of the world's most remarkable failures. So, what led them to be toast? And what can we learn from their stories today? 

Sean unpicks all the early optimism, hype and ambition. He learns about the tremendous success of a brand before hearing how it faltered, with help from expert commentators and people who were directly involved. How do they view things now and what, if anything, could have been done differently? 

The self-made millionaire and serial entrepreneur, Sam White, is alongside him, analysing the missteps that changed a brand's fortunes and reaching her own, often instructive, conclusions.  

From big tech to high street retail and, of course, food, Toast tackles the business ideas that, one way or another, ended up cooked. 

Sliced Bread returns for a new batch of investigations in February. In the new series, Greg Foot will investigate more of the latest so-called wonder products to find out whether they really are the best thing since sliced bread. In the meantime, Toast is available in the Sliced Bread feed on BBC Sounds.

Toast is a BBC Audio North production for BBC Radio 4.
