A backup battery (also referred to as a standby battery or auxiliary power source) is a secondary battery designed to provide power to a system when the primary power source fails or is disconnected. Its core function is to ensure uninterrupted operation, protect data integrity, and prevent downtime in critical applications.
Backup batteries come in various chemistries and form factors depending on the application. Common types include:
Lithium coin cells (e.g., CR2032) – used to maintain real-time clocks, BIOS/CMOS settings, and memory retention in computers, industrial controllers, and embedded systems.
Sealed lead-acid (SLA) batteries – deployed in uninterruptible power supplies (UPS), security systems, and emergency lighting for short-to-medium runtime backup.
Lithium-ion (Li-ion) and Lithium-polymer (LiPo) packs – integrated into portable electronics, medical devices, and network equipment where rechargeability and high energy density are essential.
Nickel-metal hydride (NiMH) backup cells – found in some legacy systems and applications requiring cost-effective rechargeable backup.
Key characteristics of a well-designed backup battery solution include:
Reliability – long service life and consistent performance under varying conditions.
Low self-discharge – minimal capacity loss during idle periods, especially critical for standby applications.
Fast switchover capability – seamless transition from main power to backup without system interruption.
Temperature resilience – ability to operate within the required environmental range of the host device.
Backup batteries are integral to a broad spectrum of industries, including consumer electronics (laptops, smartphones, gaming consoles), IT infrastructure (servers, storage arrays, networking gear), medical equipment (patient monitors, infusion pumps), industrial automation (PLCs, robotics), automotive electronics (ECU memory keep-alive), and smart home devices (alarm systems, smart locks).
Selecting the appropriate backup battery involves evaluating factors such as required backup duration, physical space constraints, rechargeability requirements, operating environment, and regulatory compliance. Proper design ensures that critical systems remain operational during power anomalies, safeguarding both hardware and data.

Button cells are used to power small portable electronic devices such as wrist watches, pocket calculators, and remote key fobs. Wider variants are usually called coin cells. Devices using button cells are usually designed around a cell giving a long service life, typically well over a year in continuous use in a wristwatch. Most button cells have low self-discharge, holding their charge for a long time if not used.
