Key features

At only 2.0mm thick, this card-form-factor battery slides into slim wearables, smart badges, and compact consumer devices where standard cells simply cannot fit. Enables truly flat, pocketable product

Delivers 400mAh / 1.48Wh of usable energy in a 2.0 x 44 x 57mm footprint. Optimized for low-power compact devices such as smart ID badges, electronic shelf labels, thin remote controls, and wearable s

Rated for over 500 charge-discharge cycles. Low self-discharge below 3 percent per month means the battery holds charge during long idle periods, ideal for intermittent-use devices.

Flat discharge curve maintains consistent voltage throughout use. Reliable power for Bluetooth beacons, RFID readers, and small LED indicators that demand steady operating voltage.

Soft-pack aluminum laminate construction weighs only a few grams and can tolerate minor bending during assembly. Far lighter than rigid cylindrical or prismatic alternatives.

PCM protection circuit available to guard against over-charge, over-discharge, over-current, and short circuit. JST and custom connectors supported.

UN38.3, CE, RoHS, and KC certified. Safe for air transport and compliant with consumer electronics standards in EU, North America, Korea, and global markets.

Smart badges, employee ID cards, electronic shelf labels, thin remote controls, Bluetooth trackers, portable medical patches, smart jewelry, wearable sensors, and credit-card-sized IoT devices.

Custom voltage (3.7V / 3.8V / 3.85V), wire length, connector, and branding supported. Factory-direct supply with engineering support for thin-form-factor custom battery designs.
