Do you know I think I may need to replace the batteries for my aging G4 PowerBook.
In their prime they would last at least three hours sometimes longer.
Today the first only lasted just over seventy minutes!
Batteries do wear out and I think I may need new ones or is there someway of refreshing old batteries.
At £89 apiece for new ones, I think I might try and see if there is a way of refreshing them.
