I have owned a Wahl 9655-017 for a couple of years and it has worked fine. It will be obvious that I have not used it often because I haven't had to find out what to do when the battery goes flat - until now. I have done a search for a charger and found nothing. I have found an on-line manual, but it says nothing about recharging. I have found a "transformer" available for sale, but there is no information as to whether this is the tool to recharge flat batteries. Is there anyone there to advise, please? If I can find a way of recharging my Wahl 9655-017 I will give it five stars!
