I've bought replacement batteries from both Batteries Plus and
Interstate Batteries with positive results.  I like to buy them locally,
since shipping on batteries can be a bitch.  The replacement batteries
tend to have just a few notches more Ah's than the stock ones.  This is
not a problem, you just get a few more minutes of backup power. =)
