charger design sloppiness norelco shaver arcitec [SEP] as of october the instructions specifically say that you must unplug the norelco arcitec shaver from the charger once it is fully charged if you do not you will hurt the battery i guess you are supposed to baby sit it every few hoursthis is an inexcusable design error and the principal reason i am returning this product for a full refundif norelco had said on the box you have to watch the battery icon till it stops blinking and then you have to unplug the shaver i would not have wasted my time buying it would you
