I'm reaching out regarding a solar-charged filter I own. It seems the battery has reached the end of its life cycle, and I'm wondering if there's a way to access the filter to replace the battery. Do you have any manuals or tips on how to safely perform this replacement? Additionally, the filter is malfunctioning; it won't turn on and exhibits a sparking issue, with a blinking light happening erratically. Any advice on troubleshooting this problem would also be appreciated. Thanks!
