With a battery life of up to 60 hours, the fully rechargeable P17R is a real stayer. Its main selling
 point is its sustainable battery technology, which is predominantly used in electric vehicles: the 
Safety Ytrion Cell. This is one of the safest accumulator cells on the market and with over 5,000 
charge cycles without any significant capacity loss, it is also one of the most efficient. This quality
 extends to its solid casing – elegant black on the outside, gold contacts on the inside.
