Our Cardo units are powered by a lithium-ion battery. Gradual reduction in battery capacity over time is a natural occurrence. you can slow down the deterioration pace considerably by following these easy-to-implement practices:
Avoid draining out your battery. Deep, full charges stress your power unit. Prefer more frequent shallow discharges and charges, reducing strain on the battery. We advise to charge your Cardo unit when it reaches about 20-30% battery left and – if you can – unplug it once it reaches around 80-90% battery.
Don’t store your unit for long periods without charging it periodically. Your battery naturally discharges over a long period of time, even when the unit itself is switched off. This leakage is common and expected. Don’t leave your battery empty for long, otherwise, you’ll find its full capacity has diminished when you finally take it out of storage and charge it. As a rule, charge your communicator at least once a quarter.
Protect your charging efficiency by using genuine chargers and cables made for your device and avoid cheap hardware from questionable sources.
