Battery-operated

A rechargeable battery or storage battery is a group of one or more electrochemical cells. They are known as secondary cells because their electrochemical reactions are electrically reversible. Rechargeable batteries come in many different shapes and sizes, ranging anything from a button cell to megawatt systems connected to stabilize an electrical distribution network. Several different combinations of chemicals are commonly used, including: lead-acid, nickel cadmium (NiCd), nickel metal hydride (NiMH), lithium ion (Li-ion), and lithium ion polymer (Li-ion polymer).

Rechargeable batteries have lower total cost of use and environmental impact than disposable batteries. Some rechargeable battery types are available in the same sizes as disposable types. Rechargeable batteries have higher initial cost, but can be recharged very cheaply and used many times.

Li-ion

A lithium-ion battery (sometimes Li-ion battery or LIB) is a member of a family of rechargeable battery types in which lithium ions move from the negative electrode to the positive electrode during discharge and back when charging.

Edition 04/2016 - Kann man bei dieser Fahrradlampe noch überhaupt etwas Positives festhalten, dann, dass es immerhin noch ein paar Modelle gibt, die sogar noch schlechter abschneiden. Obwohl die Sigma recht günstig ausfällt, ist selbst das nicht genug, um das Gerät noch irgendwie interessant zu machen. Das Modell lässt sich nur extrem schwer montieren, besitzt einen schwachen Akku und zeigt auch bei der Ausleuchtung von Fahrbahn und Straßenrand keine Glanzleistungen. Einen triftigen Grund, sich ausgerechnet für die Roadster USB zu entscheiden, gibt es also nicht.
