#Battery

Keycard Shell uses a replaceable 800 mAh BL-4C battery, designed to last for years. The battery is commonly used for older Nokia mobile phones and various other portable electronics. You can find the battery in many electronics stores or online. Smart tip: use your card as a lever to pop out the battery from your Shell.

If the battery fails during the Keycard Shell's warranty period, please contact us at support@keycard.tech for support.
