I keep hearing that one. How come the li-Ion in my laptop is 3 + years
old and still has 3/4 capacity (3+ hours run time)? From what I have
read on the net a lot of people abuse these batteries badly, then they
bad mouth the battery. A quote, "After my battery shuts off, I can still
get another 30 minutes out of it if I..."
Li-Ion batteries do not like to deep cycle, and they do not like to be
overcharged. Shelf life if not overheated is quite good --for a
rechargeable. They will eventually go below the safe charge level so
they need to be charged every six months or so even if not used. An
unactivated (never charged) one has a shelf life of several years,
however because people do not like to have to slow charge the battery
the first time they use it many manufactures now activate it at the factory.
Overall Li-Ion are simply the best rechargeables currently available.

Subject: batteries discharging quickly in *istD
About a month ago, I tried to use my *istD, but the batteries were
dead.
Welcome to the world of modern battery technology. Yes, you can get massive energy
supplies in small packages - the downside is shortened shelf life compared to older
technology. Others are worse. Lithium-ion batteries have a shelf life of two years. I
need a new Li-ion battery for my laptop but have yet to find a supplier that will tell me
the manufacture date of their "brand new!!!" units.
