I recently had a battery fail pretty spectacularly in a Huawei 5G router, which had spent most of its short (3 years) life sitting charged to 100%. Admittedly the replacement battery was cheap, but the failed battery was a messy hassle to change since it had swollen up so much it almost blew the housing of the router apart. And potentially dangerous if it had split open or caught on fire. If Huawei had a "limit charge" feature in this device, it would probably have avoided all that hassle!
