Question about SureFeed Microchip automatic feeder

We have rechargeable batteries, but unfortunately they don't last that long, about 2-3 weeks. Normal batteries certainly last longer. But we always have 1 set already charged, so it works quite well.

Perfect! Thanks for the answer

Difficult question. Never really looked into it. Since I bought the last one last December and the batteries are still holding out, half a year for sure.
