It's been many years that I use only rechargeable batteries. The biggest problem is that unused batteries run out quickly. The day you need it sometimes remains no more than 30 or 40% load. So sometimes I spell my spare batteries and I load security, but it reduces their life ...
So the big plus of those Duracell batteries is that they retain 80% of their one year. Regarding life, I have to AAA for 1 year, it is a fair bit to judge.
For cons, I note that they may be charged an average of 300 times, while others can be 1000 times.
