Features of Symbo Battery’s Custom 0.4mm Ultra Thin Lithium Battery
- Our ultra-thin battery can be designed to a thickness as low as 0.4mm, making it one of the thinnest card-type batteries currently available on the market. This design meets the stringent thickness requirements of various card-type devices, enabling truly lightweight end products.
- Our ultra-thin battery can support continuous discharge of 200 mA and pulse discharge of 300 mA, stably powering the high-frequency communication and sensing functions of smart cards, avoiding device response delays caused by insufficient power supply.
- Our ultra-thin battery can be operated within a widely varying temperature range of -40°C to +70°C, ensuring reliable operation in ETC vehicles in cold northern regions and even in hot southern outdoor environments.
- The annual self-discharge rate of our battery is less than 1% at 20°C, enabling stable storage for over 5 years after delivery and helping customers reduce inventory management and equipment maintenance costs.
- We also offer OEM/ODM customization services for ultra-thin batteries, including adjusting thickness, capacity, and pin layout to meet your device requirements.
