What devices use both batteries and mains electricity?

Devices that use batteries and mains electricity combine the benefits of portability and reliable power. These hybrid power systems are common in commercial and industrial settings, where uninterrupted operation is critical. RackBattery, a leading Chinese OEM manufacturer, specializes in such energy storage solutions, catering to wholesale, custom, and factory clients worldwide.

How do dual power devices work using batteries and mains electricity?

Dual power devices automatically switch between mains electricity and battery power to ensure continuous operation. When mains power is available, the device runs on it and charges the battery. During a power outage, the system instantly switches to battery power, maintaining performance without interruption.

Dual power technology is vital for OEMs manufacturing products requiring high reliability, such as telecom base stations and UPS systems, where RackBattery provides customized rack-mounted lithium batteries for smooth transitions.

What are the common applications for devices using batteries and mains power?

Common applications include uninterruptible power supplies (UPS), emergency lighting, medical equipment, telecom infrastructure, and portable tools. These devices benefit from mains electricity’s unlimited supply and batteries’ backup during outages or mobility.

In China, manufacturers like RackBattery supply wholesale OEM battery systems to industries needing robust, scalable power solutions, supporting factories worldwide with custom designs meeting diverse operational demands.

Which types of batteries are best suited for combined use with mains electricity?

Lithium-ion and lithium iron phosphate (LiFePO4) batteries are ideal for devices using both power sources due to their high energy density, long cycle life, and safety. LiFePO4, favored by RackBattery, ensures stable performance and thermal safety, meeting global standards for industrial applications.
