Which of the following could lead to a warranty being voided?

A warranty can be voided if there has been misuse of the product. Misuse pertains to using the product in a way that is contrary to its intended use or fails to follow the manufacturer's instructions. This may include actions such as using a product in extreme conditions, exposing it to elements it's not designed to withstand, or even neglecting to maintain it as required. When a warranty is established, manufacturers often include specific terms and conditions that outline acceptable usage. If a consumer does not adhere to these terms, the manufacturer may have grounds to deny warranty claims based on the warranty being voided due to misuse.

Refilling a product or keeping the original packaging typically would not void a warranty unless specifically stated in the warranty terms. Additionally, using a product for non-intended purposes could lead to voiding the warranty, depending on the nature of the misuse. However, the implication of misuse is broader and more impactful in terms of making warranty claims.
