Hi...

I was just wondering about the ave life of your powebook batteries... Thought it might be interesting to post some details, and see who gets longer battery life and why. I see some people say batteries last between 300 and 500 cycles... Well, mine is on 461 (see info below)

My powerbook:
17" 1.5GHz, 768MB
Age: 1 year and 2 months

These details from System Profiler...

Battery Information:

Battery Installed: Yes
First low level warning: No
Full Charge Capacity (mAh): 4005
Remaining Capacity (mAh): 4004
Amperage (mA): 0
Voltage (mV): 12504
Cycle Count: 461

I get bit over 2hours while surfing wirelessly. Usually I let mine drain fully before charging again. In other words, I mostly have full charge cycles, whenever possibe that is...

Lets see
Bye

Have you ever calibrated your battery? Your full charge capacity looks ridiculously low for a PowerBook's battery that is only 1.5 years old. What kind of PB do you have?

Applecare only covers defective batteries.

Apple.com says:

My PB is about 7 months old now. The battery just died last week and so I had Apple send me a replacement. I have no clue how the battery just died like that, but I got a new one! These are stats from the replacement battery.

Wow, bigbadwolf! 5144 mAh!!!!
Impressive for a pb bought back in 03...
Must be your lowish cycle count, or is that a new battery?

Anyways, no one here with a cycle count of over 500. I it might be true then, batteries last between 300 and 500 cycles (although scifrog has only 222 on his dying battery!!). Well, I'll reach 500 soon so I will see. Does the full charge capacity fall quite quickly once it starts falling?

PowerBook 17.



I also have an extra battery since I fly often and the ability to sleep swop a battery on 15s and 17s is a plus.

Ouch, I think your the winner of this thread. I picked up a extra battery for my 12" PB off craigslist from some guy in Culver City for $20 still lasts for 2 hours full capacity is 3.426Ah not too bad.

My capacity sat at about 75% for months and then recently has started dropping. So yeah, once the battery starts going it goes relatively quickly.

Ah well. Not too bad. Gets used everyday for quite a few hours. Still lasts the train journey home.

It might be new in Tiger. I don't recall seeing it before. Click on Power, under the Hardware category. And you have to have "Basic Profile" or "Full Profile" selected under the "View" menu to see the Power setting.

it's right, in tiger it's under hardware/power then on the right hand side of the screen you have the battery info, at the bottom of the list.
