Battery health is a top priority for buyers of used EVs

When Kerry Dunstan and his partner set out to buy a new electric car this summer, one of the questions they asked was, “How’s the battery?”.

They’d found a 2021 Nissan Leaf with just 29,000 miles on it, and the dealer told them the condition of the battery, or its state of health (SOH), was still around 93%.

The couple were sold. For £12,500, they got an EV with a big boot and plenty of room for passengers.

Though Mr Dunstan, a cabinetmaker who also owns a somewhat snazzier electric Volvo SUV, hasn’t quite fallen in love with the aging Leaf.

“I like sporty, jazzy cars – and it’s just a bit ‘meh’,” he says.

However, he adds the Leaf has performed exactly as expected during the three months they’ve owned it.

It used to be that age and mileage were the two headline details pored over by would-be buyers of second-hand cars. But as more people shift to electric, scrutinising the health of a car’s battery has become arguably even more important.

How has that battery been treated? Did the last owner regularly fast charge it to 100%, for example? That has the potential to shorten an EV battery’s lifespan.

This battery black box problem has put some consumers off buying a second-hand EV. But battery analytics firms say they can reveal the condition of an old EV’s battery with high accuracy. And industry experts say some EVs are lasting longer than many predicted.

Take Mr Dunstan’s Nissan Leaf. This is a model of EV built without the kind of sophisticated, liquid-based battery cooling system common to many other EVs. While Nissan has rectified this in the latest generation of Leafs, earlier models show a considerable shortening of their range year by year, according to data analysed by US insurance and research firm NimbleFins.

Mr Dunstan is unfazed. “I charge both my EVs to 100% and I put them on charge when I need to charge them – I don’t worry about it,” he says.

For people in the market for a second-hand EV who are plagued by battery anxieties, however, Austria-based firm Aviloo says it has a solution. “We really can, completely independently, determine the state of health of a battery,” says chief product officer, Patrick Schabus.

Aviloo is one of several battery analytics businesses in the market. The company, which provides battery health certificates for major UK outlet British Car Auctions, offers two products.

There’s a premium test, where EV owners plug a data logging box roughly the size of a glasses case into their car so that it can monitor battery performance while they use the car over a few days, going from 100% charge down to 10%.

Or, they can opt for a quicker flash test, which uses a different box to suck up data from the car’s battery management software and then analyse it with the help of a computer model. “We can do this at a standstill in under two minutes,” says Mr Schabus.

The premium test observes battery discharge closely, picking up fluctuations in current or voltage, and can reveal extra detailed information about the health of individual cells in the battery, says Aviloo.

Marcus Berger, Aviloo’s chief executive, says his company’s analytics results sometimes diverge “substantially” from the battery SOH percentages produced by some cars’ own built-in analytics systems.

He challenges conventional wisdom that batteries with an SOH below 80% are too far gone: “An EV with a state of health below 80% can still be a great car… It just needs to be priced [appropriately].”

In New Zealand, EV owner Lucy Hawcroft, who works in a sustainability role for an infrastructure firm, bought a Nissan Leaf with her husband roughly three years ago. She recalls getting an SOH result of 95% or so from the dealership. But a year later an independent mechanic checked the SOH again for them.

“It dropped quite a bit,” she recalls. “My husband was a bit surprised, or concerned, about that.”

However, the car still has a range of around 160km (100 miles) when fully charged. The pair mostly use it for short journeys of up to 10km. Mrs Hawcroft says she has friends whose EVs have much bigger ranges, of around 400km: “That would be ideal.”

For David Smith, sales director at Cleevely Electric Vehicles in Cheltenham, being able to analyse used EVs’ batteries in detail is a deal-maker. Most customers ask for this information, he says. His company uses SOH reports from ClearWatt, another battery analytics firm.

“They’re completely independent. We can’t interfere with the reports,” he says. “Once customers have seen the report, that aids the sale nine times out of 10.”

Matt Cleevely, managing director at Cleevely Electric Vehicles, adds that it’s often possible to replace groups of cells or modules within a battery pack – far cheaper than installing a whole new battery.

As for how you should charge your own EV in order to best take care of its battery, Simona Onori at Stanford University says, “There is likely a sweet spot between frequent fast charging and avoiding it altogether.” However, she adds that, to her knowledge, this is not something that has yet been thoroughly studied.

Despite some consumers’ wariness, battery technology has noticeably improved in recent years, says Max Reid, head of battery costs at market research firm CRU. “The older batteries might last maybe 500 to 1,000 [charging] cycles,” he explains. “Now, it’s 10,000 cycles in some of these new EV cells coming out.”

Batteries that are no longer good enough for the EV they were designed for can still be useful, says Paul Chaundy at Second Life EV Batteries, in Dorset. For instance, some of his customers are businesses that use former EV batteries to store electricity at their premises. They might have, say, six electric forklifts but a grid connection only large enough for charging ports to supply two or three of the forklifts.

Regarding the varying methodologies car manufacturers use to generate SOH reports for their own vehicles, Mr Chaundy says, “We need more standards around that, I think.”

Hair oil, ACs, soaps become costlier: How FMCG companies are dealing with Middle East supply blow – The Times of India

Hair oil, ACs, soaps become costlier: How FMCG companies are dealing with Middle East supply blow – The Times of India


Consumer goods companies in India are facing a sharp rise in input costs due to the ongoing war in the Middle East. Surging raw material prices are forcing firms to track costs on a near-daily basis, review pricing frequently, and focus on short-term decisions instead of long-term planning.As firms are struggling with volatile input costs, company executives have told ET that the sudden spike in inflation has made it harder to manage business, while also raising concerns that higher prices could hurt consumer demand. This comes at a time when consumption had started improving after the government reduced goods and services tax rates on several products last September.Havells India chief executive officer Anil Rai Gupta was cited by the financial agency as saying that the company is taking a cautious approach and reviewing the situation month by month. “I have not seen this kind of price escalation in the recent past or in recent memory. Usually, inflation happens, but it is neither so steep nor spread across all product categories… consumer offtake can get affected if the price hike is too sharp.Bajaj Consumer Care managing director Naveen Pandey said the company is closely tracking input costs and taking decisions almost daily. Speaking during the company’s earnings call last week, he said costs across the business have gone up between 20% and 60%. He added that the war has created “extreme volatility” in the prices of light liquid paraffin and packaging materials. At the same time, prices of mustard and copra have not fallen as expected and are still at pre-war levels. The company is working on cutting costs across its operations.Industry executives said the war has pushed up commodity prices and crude-linked products, increased freight costs, and made imports more expensive due to the fall in rupee. They added that even after a ceasefire, prices have not come down, and uncertainty remains over whether the conflict could start again.In the past month, companies have already raised prices in several categories, including air-conditioners, refrigerators, soaps, detergents, hair oil, apparel, decorative paints and footwear. Some companies have also reduced pack sizes to deal with higher costs. More price hikes are expected by the end of this month.Parle Products vice president Mayank Shah said the pressure on input costs is very high and the uncertainty is “killing”.Retailers are also seeing more careful spending. Trent Ltd, which runs Westside and Zudio stores, said in an investor presentation that while demand was steady at the start of the January–March quarter, the current situation is affecting consumer behaviour.“Consumers are spending with caution, resulting in moderation of discretionary spending on the back of continuing macro uncertainties and potential increase in cost of living. Structurally the demand levels and the underlying market opportunities remain strong. However, the duration and intensity of disruptions in the Middle East along with its second order effect on supply chain, commodity prices and inflation in general has potential implications for near term demand,” the company said.AWL Agri Business executive deputy chairman Angshu Mallick said the company has already increased edible oil prices by Rs 7–10 per kg to pass on higher freight costs. “Being a staples company, we hike or reduce prices immediately. As we are in basic necessities, the volume impact is usually lower,” he said.Meanwhile, the Middle East conflict is inching closer towards the two month mark. The conflict began back on February 28, when the US and Israel launched joint strikes on Iran. In retaliation, Tehran choked the crucial Strait of Hormuz, a pipeline that carries 20% of global energy supplies, straining flow across the globe.

UK retail sales rebound as motorists stock up on fuel

UK retail sales rebound as motorists stock up on fuel



UK retail sales returned to growth last month as they were pushed higher by motorists stocking up on fuel as prices shot higher because of the Iran war, according to official figures.

The Office for National Statistics (ONS) said the total volume of retail sales, which measures the quantity bought, rose by 0.7% in March.

It compared with a 0.6% fall in February, which was revised slightly lower.

The latest reading was also stronger than expected, with economists having predicted a 0.1% dip for the month.

Statisticians said March’s increase was particularly driven by a spike in demand for fuel, which saw sales volumes jump by 6.1% for the month, the highest level since April 2021.

They indicated that this was especially linked to a short period, of less than a week, of particularly elevated sales as unfolding geopolitical events in the Middle East caused a significant rise in prices at the pump.

The value of sales, the amount of money spent, for fuel was up 11.6% amid the jump in petrol and diesel prices.

Recent data from the RAC shows that petrol prices have risen by 18.5% to 157.34 pence per litre, as recorded on Wednesday.

Meanwhile, diesel is up 33.4% to an average of 189.88 pence per litre.

Elsewhere, clothing stores also had a strong month, with sales volumes across the category rising by 1.2% in March amid a boost from better weather conditions.

Technology retailers also saw sales grow after they benefited from new products launches.

However, food sales were weaker, slipping by 0.8% for the month.

The ONS said overall retail sales volumes are up 1.6% for the first three months of 2026, as the industry was also supported by positive growth in January.

ONS senior statistician Hannah Finselbach said: “Retail sales rose in the three months to March, with commercial art galleries doing well earlier in the quarter and sales in beauty products stores rising as retailers reported launching new collections.

“Motor fuel sales were up on the quarter, with retailers commenting that many motorists had been filling up their tanks in March following the start of conflict in the Middle East.”

Elliott Jordan-Doak, senior UK economist at Pantheon Macroeconomics, said: “The first batch of hard data on consumers’ spending since the start of the Iran war was better than expected.

“Granted, stocking up on motor fuels drove headline sales higher, but even excluding petrol retail sales volumes nudged up showing that households largely brushed off the initial shock of higher energy prices.”
