Okay, so these Rayovac size 13 batteries? Total game-changer for my hearing aids. I was skeptical at first, but they actually last a full week (sometimes more!). No more mid-week panic when my aids start dying during meetings.

The packaging is super convenient too – just a slim card of 60 that slips right into my bag. I stash one everywhere: purse, car, office drawer. Battery emergencies? Solved.

Price point is great for how long they last. My Bluetooth-enabled hearing aids chew through power, but these keep up no problem. Way better than the pharmacy brands I used to buy.

Pro tip: The orange tabs make them easy to spot in my battery case. And fresh expiration dates mean I'm not stuck with duds. Will absolutely keep repurchasing!
