Sl-5500 Battery Life

I recall reading somewhere in my sl5500 manuals that the battery is good for about 400 charges.  The number of charges is apparently a more critical factor than the number of hours of use.

Now, what _isn't_ clear is what counts as a charge.  Sometimes, as in after doing a soft reset, the charging light comes on even though it's been running on wall power via the adapter the whole time.

Don't know whether it's the number of times the light comes on, or the number of REAL charges that's important.  Anybody know?

TIA,

 400 Charges?? Ops, better to start looking for a new battery  

 I think they are talking about "real charges"

 I already built my own power pack with 8 x 2500 Sony AA batteries, an works pretty well

think they're talking to empty-to-full charge cycles

also how to prolong life of lithium based batteries

which basically says, they keep longer if you leave them half-charged, and keep them cool
