Later, nimh for now and rechargeable lithium battery of fast circuit, has been a very good power

detection, you can use the pulse-fast high-current charge, and also to maintain the battery in the

normal temperature range, and to close Full capacity soon, in order to prevent the charge-off,

the circuit from the high current pulse is converted to a gradual narrowing of the trickle charge,

so that even if the full power detect some deviation, the more close to full power due to the

smaller the current, at the last moment Charge current has been close to 0, no damage to the

battery, which is why lithium batteries that 80% of the pre-charge 1 hour to complete, and full of

the last 20% of the electricity it 4 hours.

Green curve for the PowerBook G4 battery charge curve, we can see that power (voltage) of the

stage before the very rapid rise in the latter stages of a very gentle, corresponding to the charge

current is that there is orange.
