Hi,

I learned this rule years ago…but it said to wait 2 or 3 minutes. I use 675 Power One batteries in my powerful Phonaks and have gone 3 weeks on a regular basis before changing batteries.
I wear 12 to 13 hours daily usually. Power One are excellent batteries and 675 batteries are really big for hearing aids. I passed this on to my Audi…she didn’t know….and she passed on to her patients. I generally change a day or two ahead of the 3 week limit so as not to be caught short and to have time to let them come up to full power. I have had them go longer than 3 weeks during the lockdown to see how much further they go. I also switch batteries from left to right and right to left every morning as I tend to remove the left one earlier.
So I think it’s valid Information that you should let these batteries with stick on tabs take the time to rev up to full power.

BTW my library recycles old batteries so I keep a ziploc baggie of used batteries until it’s full and take it over. Boy do we use a lot of batteries between my house and my daughter’s house. You wouldn’t think so with all the recharging devices we both have.
