Most rechargable 9V batteries are made of 6 cells in series, each providing 1.2V thus the 7.2 volts. The following is a quote from a New Zealand Dick Smith Electronics Catalogue: "Unlike most 9V batteries, which are really 7.2V, this is a true 9V battery that delivers 100mAh." It refers to a Varta TR7/8 rechargable battery. The 9V rechargable batteries should work with your recharger if the recharger provides 10mA constant current at over 9V.
