Thanks.
The answer is yes, but as Oliver mentioned, how much is totally dependent on the CF card. Test results have shown that certain SanDisk cards will decrease power off battery life by as little as 0.5% while certain Buterfly CF cards can decrease power off battery life by as much as 10%. When the Visor is "on" the power used by the CF card in its "stand-by" state is insignificant compared to the overall power drain.
What this means is that if your normal power-off battery life is 30 days (for example), keeping a CF card in all the time could reduce that by as much as 3 days for a power hungry CF card or as little as 3.6 hours for a good card. Probably not a big concern either way for most users, but if your Visor sits idle most of the time, the difference could add up to one set of AAA batteries a year.
