RECHARGEABLE VL TECHNOLOGY

VL technology refers to a rechargeable lithium button cell battery based on lithium vanadium pentoxide.

It must not be replaced with a non-rechargeable CR-type lithium battery, unless the device's circuitry is designed for that purpose. A car key designed for a VL2020 typically recharges the battery via the vehicle's or the key's internal circuitry.

MAIN APPLICATIONS
