I’ve been using the HM-RC-Key4-3 with my Keymatic system for a while now, and I’ve noticed an issue with the battery life that I wanted to share and get some advice on. Despite only using it sporadically—about 2-3 times a week—the battery seems to drain completely within a month. I’ve tried different brands of batteries, but the result is always the same: extremely low residual voltage after about four weeks. I’ve even returned the device twice and purchased an extra one from another retailer, but the problem persists.
I’m curious to know if this is normal behavior for this device or if there’s something I might be missing. Maybe there’s a setting or a usage tip that could help extend the battery life? I’d love to hear from anyone who has experience with this or similar devices.
In the meantime, I’ve started keeping spare batteries on hand to minimize downtime. It’s a bit of a hassle, but it’s better than being caught without a working remote. If anyone has any suggestions or insights, I’d really appreciate it! Let’s keep the discussion going and help each other troubleshoot this issue.
