These batteries do not hold as long as those of the big brands in my Renault remote. For the price we say that even if the changes more often it is cheaper still. The first lasted almost a year, but the others had less and less time as the date of use is reached. 5 results in 2 years. If you do use one at a time, it is best to buy 2 in a good brand such as Duracell.
