The reading when I turn the HT on straight off of the charger is 8.6V. I have it attached to a Signal Staff OSJ collapsible J pole. I use the standard FNB83 battery. I'm using the standard Yaesu drop charger:

I have three FNB83 batteries: one came with the used unit, the other two I bought one year ago and a couple of months ago respectively. All three of them seem to eat up juice at a faster rate than usual, although that's a subjective measure. This happens even when I'm not transmitting, with the HT just turned on. Once the charge drops to about 7.8V I'm told my Tx is very scratchy. Once it drops below 7.6V I can't transmit. This just seems rather odd, three different batteries of different ages displaying this behavior.
