To believe the use of the color green on the packaging and the bodies of the four rechargeable batteries, their purchase is certainly a highly ecological gesture (and environmentalist) for the planet and our environment. It's always fun! Otherwise these batteries do their job; they undertake to restore electricity and without flinching. For now and for a month, they work perfectly in conjunction with my cordless phone Siemens Gigaset C595, giving it a range of almost a week (without charge) in moderate use. It seems to me correct!
