laptop battery question

[Stephen Trapani]

So my Lithium-ion battery on my last two iBooks gave out after 13
months. I figure I'm doing something wrong.

I have used the laptop often plugged in, is that the problem?

I bought a new battery recently and I want to make it last longer. My
question is: Is it okay to put the dead battery in while I have it
plugged in at home and switch the batteries out with the good one when
I'm going to use it away from the outlet?

Probably would be more effective, for the overall battery life, to actually
run the system on the battery for the total time period once a month or so.
Allowing the battery to actually discharge to probably the warning level
<10%.
Recharge the battery, or just use the system with AC power connected and the
new battery installed will recharge it.
The operations manual should have relative information about battery care.
?Use it or loose it? IMHO
