I bought this set of 10 batteries in November 2013 al origin for radio control my roller shutters but I did not because from a trial it n 'was inconclusive .Surprise is this type of battery which equipped the remote control of my car so all telling when in January 2014 the message Low Battery appears in my auto.Remplacement battery, everything works perfect. If I put this message this morning is that the message "low battery" comes again appear, but I must point out to you that this is the sixth time in 13 months !!!! These batteries take on average two months for normal use when the original battery held 3 years. (I'm confident about the 10 Battery Sales m there are two left !!!!!)
