Date: Wed, 17 Dec 2003 11:18:38 -0700 New alkaline batteries are significantly above their 1.5v nominal value when unloaded. My recollection is 1.8v or more. 4x1.8v = 7.2v, which will damage electronic parts. Even 4x1.5v = 6v exceeds the typical "absolute max" voltage of 5v parts (5.5v). When you put alkalines in, you probably will get away with it because the unit will draw them down pretty quickly to the safe voltage range, hopefully without damaging anything. Even if there is no damage apparent, you are stressing the parts which can cause premature failure. Personally, I see no point in risking a $200++ unit, even if the batteries were free. gvb > -----Original Message----- > From: owner-rockbox_at_cool.haxx.se [mailto:owner-rockbox_at_cool.haxx.se]On > Behalf Of eD\/ARd0 F/\KEn^M3 > Sent: Wednesday, December 17, 2003 11:46 AM > To: rockbox_at_cool.haxx.se > Subject: Re: Batteries? > > > ----- Original Message ----- > From: "Brian" <GCRockboxer13_at_columbus.rr.com> > To: <rockbox_at_cool.haxx.se> > Sent: Wednesday, December 17, 2003 7:26 AM > Subject: Re: Batteries? > > > snip > > and a few seconds after each HD spindown there was a very > loud noise as if > > the hard drive was trying to stop and go at the same time. > > > > Moral of the story: alkaline batteries = never. > > Actually, that sounds like what will happen when the HD can't > get enough > juice to spin up properly.This will happen with any type of battery. > > ****************************************** The information contained in, or attached to, this e-mail, may contain confidential information and is intended solely for the use of the individual or entity to whom they are addressed and may be subject to legal privilege.
