Pardon if this is an absurd question, but is there a power switch that you might not be turning off? I have an H2 and a Q3 and they turn off completely when not in use... The manual says hold the power/ hold button down for 1 second to turn off. <L> On Dec 13, 2010, at 5:16 AM, Frank Strauss wrote: Hello all-As a result of an October post, I bought a Zoom H1 recordedr. It is, for the most part, a very nice little unit. Having said that, the first one I got would discharge a battery in about a day and half, with the unit turned off. I returned it and got a replacement. It also discharges the battery in about a day and a half. If anyone else is using this unit, have you had similar battery performance? Is it possible that you can only use this unit by taking the battery out while it's not being used? I don't mind doing that, but you have to re-enter the date and time info every time the battery is removed and then replaced. Thanks.
