Which? reveals the best vs worst AA disposable batteries

Our tough battery tests have discovered that the best AA batteries last more than two and a half hours longer than the worst in your most power-sapping devices. And up to seven hours longer in devices like games consoles. Our latest tests included AA batteries from 15 different brands including Duracell, Energizer, and Panasonic, as well as own-brands from the likes of Aldi, Amazon, Asda, Lidl, Sainsbury’s, Tesco and more.

We know that Which? members use batteries in a range of different devices, so we test batteries in three different scenarios to identify which batteries last the longest in your devices. We’ve also discovered that price is no indicator of quality – we’ve discovered bargain Best Buys, as well as expensive Don’t Buys.

AA disposable battery reviews

Our tough lab tests revealed a big difference between the best batteries and the worst.

Put a set of one of our Best Buy AA disposable batteries in your most power-hungry devices, such as a camera or torch, and they will last nearly two and a half hours longer than the worst. Put them in a medium-drain device, like a games console, and you’ll get nearly seven extra hours. It’s important that you choose the right battery for your device.

As our graph above shows, Best Buy 1 is great in higher-powered devices, but you wouldn’t want to waste it in a low-drain device, like a clock, as it doesn’t last as long as its rivals.

Don’t forget to recycle your batteries

Which? members are pretty good at recycling batteries, our latest survey found.

Some 65% of you always recycle your disposable batteries, and a further 11% do so often. However, 9% rarely recycle batteries and 7% said they never do so. Batteries chucked in the bin can end up in a landfill, where the chemicals they contain could leak into the ground.

No one needs to find recycling a chore, and the good news is that recycling your batteries has never been easier. Aldi, Asda, Lidl, Morrisons, Sainsbury’s, Tesco and Waitrose all have collection points in their stores – ask if you can’t immediately see them. Any retailer selling more than a pack of AA batteries per day (over 32kg of batteries sold per year) has to have a collection point (the rules are different for car and industrial batteries).

Your council website should also list your local household waste recycling centres. Many town halls, libraries, schools and charities will take them too.

New Fairy bottle made from 100% recycled plastic

A new recyclable Fairy washing-up liquid bottle is launching next year, which the manufacturer says aims to tackle the problem of plastic waste. The innovative bottle will be created using a mixture of ocean plastic collected from beaches around the world, and post-consumer recycled plastic. Keep scrolling for the details.

The new Fairy Ocean Plastic bottle

In a bid to raise awareness over the issue of ocean plastic, Procter & Gamble (P&G) is planning on selling a Fairy washing-up liquid bottle made from 100% recycled plastic. The new bottle will arrive next year, with the UK launch seeing 320,000 bottles go on sale. In a press release, the group highlighted its commitment to recycled plastic, revealing that it diverts 8,000 tonnes of plastic from landfill every year for use in transparent bottles.

So how will the new Fairy bottle be created? Plastic that washes up onto the UK’s beaches will be collected by volunteers, ground into pellets and then transported to P&G. From there, the material is transformed into Fairy Ocean Plastic bottles.

The bottles are fully recyclable, so their plastic will continue to be reused when you’re finished with them.

Earlier this week, Lisa Svensson, Global director for Ocean UN Environment, described the problem of ocean plastic as a ‘planetary crisis’. She added: ‘In a few short decades since we discovered the convenience of plastics, we are ruining the ecosystem of the ocean.’ We’ve seen other big-name brands addressing the issue of ocean plastic in the past few months, too.

Earlier this year, Adidas unveiled the EQT Support ADV sneaker, which is knitted from yarns made of recycled plastic waste.

It’s the perfect time of year for big gatherings of friends and family, but once the crowds disperse, the task of scrubbing and scraping your way through piles of plates begins.

Don’t pay more than you need to

Washing-up liquid probably isn’t the priciest item on your shopping list, but you can still save money without compromising on cleaning power. Our tests revealed one great value Best Buy washing-up liquid which costs less than GBP1 per bottle – that’s less that a third of the price of the most expensive option (per 100ml). Plus, Best Buy washing-up liquids can power through more grimy plates than others, so you’ll buy fewer bottles in the long run.

Ever splashed out for ‘premium’ options? We found one washing-up liquid that did just as well as its ‘premium’ counterpart, so you could be paying for ‘extra power’ that isn’t really there. Read all of our washing-up liquid reviews[2] to find out which it was.

Plus, our tests also revealed four Don’t Buy washing up liquids[3] that you might be best to avoid.

New, tough tests

Anyone who has tackled a cheesy lasagne dish or a gravy-encrusted roasting tin will know that baked-on fat is the most difficult foodstuff to wash off by hand. In 2015, we added a new ‘tough grease’ element to our washing-up liquid tests that revealed big differences between products. This year, we’ve enhanced this part of the test to make it even more realistic.

First, we bake tough grease into a metal tile. Then, we wipe it with even strokes of a sponge containing each washing-up liquid and count how many strokes it takes for all the baked-on grease to be completely removed. The results really separated the best from the rest – one standout performer cleared all the grease in just seven swipes, while the worst hadn’t shifted it after 100 strokes.

Our tests also measure how well each washing-up liquid removes lighter fat and grease, and how long the foam lasts when you’re cleaning everyday grime. That means that the washing-up liquids that score top marks are good all-round choices, while those that score poorly will leave you using extra elbow grease. For all the details on our rigorous testing process, find out how we test washing-up liquid[4].
