Title: not worthy the trouble of replacing the battery in the Norelco
Review: I first tried to replace the NiCd battery with the new Metalhyride battery since they have a much larger current storage capacity. It turns out that the MH batteries tend to leak current so their voltage will drop steadily even without use. I then decided to replace the original NiCd battery with this one from Amazon.com (supposed to be exactly like the original one in my Norelco shaver). The battery turns out to last at most 14 shaves (ie two week) rather than the over 20 shaves I used to get from the original battery. After several charges I am getting only 10 shaves per charge. If this number drops further I would throw away the shaver. If I had known earlier that the replacement batteries are so much inferior to the original ones I would have bought a new shaver.
