Duracell cells last an average of 107 hours.
Many users are disappointed that the 312 size battery needs to be replaced every month.
I purchased a batch of batteries in 2015 and found that they do not last as long as the previous ones I purchased.
77% praised the long-lasting battery life, while 23% experienced shorter duration
I compared the battery life of the original Power One batteries with the new ones I purchased and found that the new ones had a shorter battery life of approximately 7 days, whereas the original ones lasted 9-10 days.
I estimate that the batteries will last less than a year.
I compared the battery life of the product with ENERGIZER brand battery and found it to be poor. The product's battery life is only 2 days compared to ENERGIZER's 6-7 days.
In my hearing aids, the batteries only last for 3 days.
85% liked the durable battery construction, but 15% experienced premature wear
Power One cells last an average of 124 hours, which is 15% more than Duracell cells.
I have noticed that the new batteries are not as durable as I was hoping for, despite having the same habits as before.
