Correct voltage for external battery 6d ?
I have bought a power adapter from ebay which should be put into the battery slot and connected to a DC source of about 7.2...8 volts. So a sixpack NiMH AA should work, but the open voltage when fresh charged is 8.1...8.4 volts measured with my multimeter. Normal AA rechargeables have an open voltage of 1.35..1.4V when freshly charged, so this is correct as it is exactly 6 times that voltage. Because of this (slight) overvoltage I am reluctant to connect it.
Does this damage the camera ?
