Cellonic

CELLONIC is a German battery and accessories brand owned by subtel GmbH, a Berlin-based specialist in power solutions for mobile devices. The brand develops and sells rechargeable batteries, chargers, power adapters, cables and related accessories for everyday consumer electronics, positioning itself as a direct-from-manufacturer alternative to original equipment manufacturer (OEM) parts. Its catalogue covers more than 2,700 battery models compatible with over 100,000 devices, spanning laptops, tablets, smartphones, cameras, cordless tools, robotic lawnmowers, vacuum cleaners, loudspeakers, headsets, navigation devices, smartwatches and fitness trackers, games consoles, smart-home devices and barcode scanners. The brand's central proposition is sustainability through repair: "Replace the battery, not the device." CELLONIC argues that everyday devices usually fail because of their battery rather than the device itself, so a suitable replacement extends product life, saves money and reduces electronic waste. Products are designed and tested in Germany, dispatched from Germany, and sold across Europe with a three-year warranty. Orders, dispatch and customer service are handled through the parent company's shop, subtel.eu, without intermediaries. CELLONIC traces its expertise to 2004, when subtel GmbH was founded in Berlin. The brand itself is presented as having more than 21 years of experience in batteries. It serves both consumers and business customers, with multilingual support and a logistics network described as stretching from Lisbon to Helsinki. Because it is an own brand rather than a white-label reseller, subtel says it develops, tests and takes full responsibility for the products. As a private-label product brand of a privately held German company, CELLONIC does not trade on a stock exchange and does not publish separate financial results. Its identity is closely tied to its parent, subtel GmbH, which handles the commercial infrastructure behind the brand.

CELLONIC is the in-house battery brand of subtel GmbH, a Berlin-based company specialising in power solutions for mobile devices. According to the brand's own account, subtel GmbH was founded in 2004, and CELLONIC presents itself as drawing on more than 21 years of battery expertise. The brand was created around a simple observation: everyday devices rarely fail because of a fault in the device itself; they fail because of the battery. From that premise, CELLONIC built a catalogue of replacement batteries, chargers and accessories intended to let users keep their existing devices rather than replace them. The brand operates as an own brand rather than a white-label product line. subtel states that CELLONIC products are developed, tested and fully accounted for by the company itself, with design and testing in Germany and distribution throughout Europe. Orders, dispatch and customer service run through the parent company's shop, subtel.eu, with no middlemen. The brand describes its logistics and support network as stretching from Lisbon to Helsinki, with multilingual customer service and dispatch from Germany. Over time, CELLONIC expanded its range beyond a narrow set of device categories. Its catalogue now covers more than 2,700 battery models compatible with over 100,000 devices, spanning laptops, tablets, smartphones, cameras, cordless tools, robotic lawnmowers, vacuum cleaners, loudspeakers, headsets, navigation devices, smartwatches and fitness trackers, games consoles, smart-home devices and barcode scanners, alongside essentials such as cables, power adapters and power banks. The brand markets a three-year warranty across its products and serves both consumers and business customers. CELLONIC's public messaging centres on sustainability and repair. Its slogan, "Replace the battery, not the device," frames replacement batteries as a way to extend product lifecycles, save money and reduce electronic waste. The brand also emphasises independence from manufacturers' charging cycles and the ability to keep a favourite device working after its original battery has failed. As a private-label brand of a privately held German company, CELLONIC does not report separate financial results or trade on a stock exchange.
