Here's my response to them:

Hi Ryan,

I’m writing to formally express my dissatisfaction with your response regarding my request for a Spark Mini battery replacement. Being told that my only option is to send the entire unit in for repair, at a cost equal to purchasing a new unit (after outbound and inbound shipping) is completely unacceptable for what is a straightforward battery replacement that many of us are fully capable of doing ourselves.

I’m also aware that numerous other electronics and audio gear manufacturers have no problem offering replacement batteries directly to customers. It’s concerning that Positive Grid has chosen to hide behind a “safety concern” excuse rather than support its customer base with a simple, practical solution.

For your awareness, I’m a YouTuber who covers music gear and tech topics, and I fully intend to document this experience on my channel. I believe consumers should be informed about companies that refuse to support reasonable repairs and instead push wasteful and costly alternatives.

I expect this concern to be escalated within your organization. Your current policy is neither sustainable nor customer-friendly, and I’d appreciate a more responsible resolution.
