CAUTION: alt = throw away battery

I was in the beginning also totally convinced by the device.
After 2.5 years, then weakened the battery.
Batteries are Verbrauchsmateriel and do not last forever even with the most careful treatment.
But since I already like the first reached 8h intercom wanted talk time - and not only 3h as the end - I've asked myself, what can be done.

Information from Cardo:
Throw away and buy another!
An exchange of batteries after the warranty is not provided!

Who can afford to let up after 2 years to buy new parts so happy.
After 2 years, I had about 5 hours of talk time, as far as I can remember, that was already borderline for my taste.

As I know to help me, I have the battery itself then replaced, and documented.
Just search for "Cardo To replace the battery" googling and you land on my instructions.

I can recommend the device therefore only conditionally.
With new batteries the thing works almost perfect, but it is not intended to be to change or replace the battery does not go.
