What 'should' the full charge capacity of a new Macbook battery be?

The new Late 2008 batteries are nominally 4400 MaH.

Charge Information:
Charge remaining (mAh): 4212
Fully charged: Yes
Charging: No
Full charge capacity (mAh): 4212

I actually got paranoid when I tried to do a search online; there was an old discussion over at Macrumors and people were getting about 5200-ish on their full charge capacity. Can anyone be sure that our current full charge capacity is normal? My Macbook is only 3 days old and I'd be really upset if I got a dud battery.

5200-5500 MaH is the typical full charge capacity of the older models' batteries. What you are seeing is correct. The new models have a 50 watt-hour battery - 4.2 Amps x 12 volts for 1 hour nominally or about 50 watt-hours.

Thanks, Kappy! That's really reassuring... Now I can sleep well :P

My new mb 2.4ghz is usually around 4210 to 4270. I was wondering if this is normal as well because my 6 month old mbp was always around 5530.

My 2.4GHZ model has five charge cycles on it and it is now showing 4254 as the full charge capacity. I hope this doesn't keep declining. My old white plastic macbook battery was bomb. This has gotten better after each charge cycle though. I went about 3 hours and 45 minutes today and still had 33% left when I plugged it in. I really hope I start seeing closer to five like my other one is able to achieve.

These are the figures I'm getting - seems to be a little low from the numbers I'm seeing above. I haven't seen the estimated time remaining on the battery much more than 3 hours after being fully charged (currently at 2:40 - after only just unplugging it with about 3/4 brightness).

What time estimates are people seeing when web-browsing (nothing running in the background)? I'm wondering what a 100mAh drop actually has on the effective battery life. Anyone think these numbers are abnormal? Can I expect these to improve at all after full charge cycles (I'm guessing not)?

Cheers.

My charge time has improved significantly. I had my computer running off battery power during class yesterday from 9:30 in the morning until about 1:20. It had 33% when I put it to sleep and charged all the way back up to 100% in about 3 hours and 45 minutes. The battery is lasting longer too, now that it has gone through 5 charge cycles. I'm running on battery now with screen brightness at 50% and I have 97% remaining (says 4 hours). I'm on safari, listening to iTunes, and I also have mail and iCal open. I think the battery needs to go through a few charge cycles before its true potential is realized.

After 1 full discharge/recharge - I've now got an extra couple of mAh on my capacity! Now if I just do this another 100 times...

Another strange thing - even though I literally just unplugged it, I've already used 51mAh?

where do you find this information re the battery?

This is my first MB so is it like the iphone where the battery gets better over the first few weeks - should i be running it down fully and going through a few full charge cycles to maximise my battery life?

found the info - is less then everybody else's - help - will this improve?

My two week old Macbook seems on the low side too... the full charge capacity just recently dropped below 4000 mAh, and when I run it off battery power, the estimate is usually only 2-3 hours. I tried calibrating the battery, it didn't help.

Hi,
my 2 weeks old MacBook also suffers from draining power.

CoconutBattery shows the following data:

Current capacity: 4038 mAh (constantly falling)
Original capacity 4100 mAh

Should I ask for a new battery ?

I've got a 2yo 15" MacBookPro (C2D generation, October 2006), and I've just ordered a brand new battery to replace the old one (which had less than 30 minutes of capacity). The new battery just arrived (10 minutes ago), and shows the following numbers:

- Full charge capacity (mAh) 5569
- Cycle count 0 (well, its only been in the machine for 10 minutes now)
- Amperage (mA): 784
- Voltage (mV): 12257
