Sennheiser's new Momentum 5 Wireless headphones claim up to 57 hours of battery life with ANC on, nearly double rivals like the Sony WH-1000XM6 and Bowers & Wilkins Px7 S3. The headphones also feature a battery that users can swap themselves by removing four screws under the ear pad, though the replacement battery isn't yet sold separately. They support a wide range of audio codecs including aptX Lossless and offer both wired and USB-C lossless playback.

Canadian auto parts maker Magna International is investing an additional $35 million into Yuma Energy, a Bengaluru-based battery-swapping startup spun out of Yulu in 2023. The new funding raises Magna's stake beyond the 51% it held since the joint venture began, diluting Yulu's share, though the exact new split wasn't disclosed. Yuma has completed over 60 million swaps and has roughly 100,000 batteries deployed for electric two- and three-wheelers.

In 1799, Italian physicist Alessandro Volta built a stack of alternating zinc and copper discs separated by brine-soaked paper, creating the first device to produce a steady electric current. His invention, later called the voltaic pile, was a direct rebuttal to fellow scientist Luigi Galvani's theory that dissected frog legs twitched due to an innate 'animal electricity' generated within living tissue. Volta argued instead that the electricity came from the contact between two different metals, with the frog's moist tissue merely acting as a conductor.

Researchers led by CSIRO's James Quach built a quantum battery prototype that charges in femtoseconds using a phenomenon called superabsorption, where organic dye molecules packed between two mirrors respond collectively to laser light. Unlike conventional batteries, this device charges faster as more molecules are added, and the team successfully extracted a small electrical current from it, extending earlier 2022 research that only showed rapid energy absorption.

The Open Battery Information project has retired its old Python/Tkinter desktop app in favor of a new web-based interface, OBI-1, that connects directly to an Arduino or ESP32-C3 via Web Serial. The tool lets users read and reset battery management system (BMS) faults without installing any software, including flashing firmware straight from the browser.

Bentley let Ars Technica ride in a camouflaged prototype of the Torcal, its debut battery-electric model, shorter than the Bentayga but similarly spacious inside. The SUV shares underlying engineering with the Porsche Cayenne EV and targets roughly 300 miles of EPA range with 400 kW DC fast-charging, producing over 850 PS and more than 1,000 Nm of torque.

Xiaomi has released the Redmi Note 17 Pro Max worldwide, featuring a massive 10,000mAh silicon-carbon battery, though European units get a slightly smaller 9,210mAh version. The device supports 100W wired charging, promising a full charge in 80 minutes and all-day power from just a 20-minute top-up, plus 27W reverse charging but no wireless option. It also boasts rugged durability with IP68/IP69/IP69K ratings and Gorilla Glass Victus 2 protection, though it runs a downgraded Snapdragon 6 Gen 5 chip compared to its predecessor.

Leaks ahead of Apple's confirmed September 9 event point to a foldable iPhone Ultra launching seven years after Samsung's first foldable phone. Reports describe a nearly crease-free inner display, an ultra-thin body powered by the A20 Pro chip and a vapor chamber for cooling, and a liquid-metal hinge built on technology Apple licensed more than 15 years ago.

A Korean leaker claims Samsung built several Galaxy S27 Ultra prototypes, including one with a 7,000mAh battery and versions that dropped the S Pen to fit it. Samsung is said to have abandoned that extreme option, instead settling on a 5,700mAh to 6,000mAh target, possibly using silicon-carbon battery technology.

After the April 2025 blackout across Spain and Portugal shut down its production lines and spoiled tonnes of meat, Spanish processor Fribin lost hundreds of thousands of euros in a single incident. The company has since bought two five-megawatt-hour battery storage modules, together worth about €1.5m, partly funded by EU Next Generation grants, to keep operations running during future outages.
