What warranty entitlement do I have?

What does the SIGMA LOOP-LIGHT-SYSTEM stand for?

Is it possible to replace the MONO’s battery?
Yes, the battery can be replaced. This process can only be conducted by the SIGMA SPORT service department. Lithium-ion batteries are known for losing some of their capacity over time and/or after a high number of charge cycles. The MONO’s lithium-ion battery retains at least 75% of its capacity for the first two years or 300 charge cycles – whichever is reached first. Upon expiry of this warranty period, the MONO’s battery can be replaced by the SIGMA SPORT service department subject to the provision of a purchase receipt. Price on request. If you store the MONO for a long time (more than three months) without use, ensure that you do so at a temperature of between 0°C and 20°C and a low humidity level. The pre storage charge status should be approximately 60%.
Can the MONO RL also be operated with different single-use or rechargeable batteries?
