91% liked the ease of recharging, but 9% found it slow
The batteries come in small re-sealable dispenser cards holding six batteries, which is the most convenient thing about them.
These batteries give me at least an extra day, sometimes two, than the cheaper batteries I was using, which is a positive aspect of charging convenience.
The product is perfect for carrying around as it is thin and can fit in the wallet.
I received the packs individually, which makes storing them inconvenient.

90% liked the durable battery construction, but 10% experienced premature wear
I can get at least four days use from the batteries if I wear my aids for about 8-10 hours a day.
I have no complaints about the batteries as they have a similar lifespan as others.
I compared the durability of two battery brands and found that Rayovac batteries last only 2-3 days, while ZeniPower HP brand batteries last 6-7 days.
91% appreciated the easy-to-use design
I will return to purchase from this source because of the good price and delivery times.
I love the dial packaging of the batteries.
I am pleased with the batteries, but there is no information about user-friendly design of hearing-aid-battery chargers.
