Keeping battery in G4 when plugged in

Message #1 - Posted 2004/01/06 - Karen

Finally got the G4 powerbook and have yet to start it up (time and exhaustion) but once it's up an running I'm concerned about the effects on the battery when plugged in the AC outlet. I unknowingly destroyed the battery in my second Tosh Sat Pro by keeping the battery in when using the machine plugged into the wall (sometimes for 18 hours a day, I use computers a lot). With my new Tosh 6100 I remove the battery most of the time and just use the wall AC outlet and periodically charge the battery, then remove it.

Is this necessary on a G4 powerbook? Can harm be done by removing the charged battery and using it on AC power only or is it like they claim with the iPod, that the battery *cannot* be overcharged. I don't want to have a dead battery in a years time, or one that will never again hold a charge from long term AC usage.

Thanks,

Karen

FWIW, My PB's over 2 years old (Mercury) and I use it mostly plugged in with the battery sitting at 100%. But about once a week I unplug the charger cable and use the PB until I get the battery-low warning, then plug it back in again. This way I cycle the battery once in a while. However, with this type battery, I don't think this exercise is really required.

I leave my Mac PowerBook (1998 model G3 Wallstreet) plugged in all the time with the battery in. Does not hurt the battery, and provides power backup in case of power line transient. When I travel, I just unplug it, put it to sleep and carry it with me. Works fine.

I think all the Mac laptops since about 1997 have Lithium-Ion batteries. I understand these do not need to be cycled trough full discharge and back to full charge to keep their charge capacity. Further, I believe the life of these batteries is measured in charge-discharge cycles, so keeping it fully charged may prolong the number of years you get on a battery.

All rechargeable batteries of any type eventually die, so don't expect more than a few years life from a battery no matter how you treat it.

Using the PowerBook and AC/battery combination in any manner with never a problem will be the first of many pleasant surprises for you. Enjoy.

Both batteries and the charger/manager in the laptop
has come a long way since that Toshiba was made --
not to worry. Leave it connected.
