YOU are the one killing your Lithium-Ion or Lithium-Polymer batteries by
not understanding how to maintain them properly......
Sellphone bois just love to show their dicks by bragging how long their
sellphone will run between charges....a week, a month, etc. This penis
envy is what kills the Li-xx batteries very prematurely.
Unlike Ni-Cd or Ni-Mh rechargeables that SHOULD be fully discharged at
some interval and stored in a discharged state, Li-XX batteries are more
like your lead acid car battery. Deep discharging them without really
good reason except vanity consumes them in short order.
Inside each Li-xx battery is a custom IC that controls the battery's
charge and discharge cycle. You don't ever see, I hope, your sellphone
go "dim" from a dead battery, because the IC in the battery is set to
prevent you discharging it past about 50% of its capacity, half
discharged. This is the only way to prevent permanent damage, which
deep cycling a Li-xx battery does, irreparably.
If you'd like to get 4, 5, even 7 or 8 years out of one battery, the
solution is very simple....never deep discharge it. Plug it in at every
opportunity and recharge it until the IC cuts off the charge, even
though you've only used it a couple of hours and it shows full scale on
the meter. The chemistry just loves to be float charged, just like lead
acid does, but for a different reason.
I have an old 120GB MP3 player that's going on 6 years old. It's a
Digital Mind Xclef 500 and, though simple, is still my favorite because
of its sheer monsterous memory that can store days of music without
playing the same song over. Even today, 120GB is pretty large. It has
no DRM or nanny games you boys know I hate. Plugged into any PC,
Windoze treats it as just another external hard disk drive and will load
it accordingly. It also records MP3, has an FM radio that actually
works great, and is just plain simple to use with its side-mounted
multifunction jog lever you can use driving without looking away from
the road.
The battery in it is a Korean Li-Ion hard wired into it like an iPhone.
It has never been replaced and will still run it all day and have 60%
charge left when I plug it back in for tomorrow. Its real leather case
has worn the paint off the aluminum case, I think improving its looks.
It's a large, heavy beast that uses standard laptop drives even a
standard battery, if I ever need one. Feed it +5VDC from any charger
and plug it into your stereo and you're ready for music!....
