That’s exactly why I’m sold on rechargeables 
Sorry to hear about your battle with COVID-19 - I hope you’re now fully recovered. I think you would’ve found rechargeables a boon in hospital. Just pop your HAs in the charger/drier each night. No need to possibly impose on family to get you batteries.
And it’s really no hassle to give the rechargeables a short pre-event boost before your romantic evening . How can you be sure your batteries won’t give up just as your partner’s sharing sweet secrets with you?
