New battery lowers MBP temperature??? Am I going insane?

I got my replacement MBP battery yesterday and, after installing and fully charging it, began using my machine for a long work session.
Previously, the machine ran at an average temperature of 57-59 degrees C, but now it's running at an average of 40-43 degrees C. I haven't changed my useage of the machine in any significant way or stopped using any high-intensity applications, so I'm at a total loss to explain the nearly 20 degree temperature drop.
Surely there can be no connection between the battery and the temperature of the MBP, but I have to trust the evidence of my temperature monitor software and the fact that I can now comfortably rest my hands on parts of the machine that were very warm before.
Has anyone else noticed this or have I totally lost touch with reality? I thought I'd ask here before I ran off to my therapist and asked to be committed.
On edit: I didn't mention that my battery was replaced under the recall scheme, so I'm wondering if maybe the early batteries were, in part, responsible for the machine's high temperature.

Well, I guess I'm one of the lucky ones... I have a mbp week 11, and the machine has worked all day very cool, about 55°C max (temperature monitor, CPU) doing only light stuff like internet browsing, adium and playing music. I just finished some backing up and the mean CPU temp rose to about 65°C, but it's now after 10' down to 54°C. So it's not one of the Cookbooks and for that I'm glad!
The system freezes from time to time, but ever since I made an archive and install, things are working much better.
It has the whine though, but I keep it quiet with ShhMBP. Some people say this kills battery life...I get almost 4h now with the new battery...so I'm very happy with this.
So like I said before, now that the temp is down (new battery) and the whine is gone (ShhMBP), I'm very pleased with this machine!
I just contacted the local Apple store to hear what they do with mbp's that whine and how long it takes to replace the logic board...I still haven't decide if I'm gonna take it in though...it's kinda hard to live without a computer.

Received new battery - Now MBP runs much hotter

My old battery had no poblems - MBP had no problem, now with new battery it is running much hotter and fans come on big time. Had no noise at all with first battery. Guess I'll call Apple and find out what's going on.

I'm trying out the new battery (normal use of MBP is with line current and external kvm). On battery power the CPU temp stays in the fifties -- much hotter when plugged in for some reason. Also, on battery, there is a new, faint but noticeable noise, not steady but about one-second bursts with a microsecond inbetween, so 50-60 Hz. I'm thinking of visiting a genius.
BREAKING NEWS: As the fuel gauge went down below 1:10 hr remaining, the menu bar icon shifted to "Calculating", with a red bar at the left end. System profiler shows all zeros in the Power submenu. Something is definitely amiss.

New battery for MBP wont fully charge

I have a new battery for my mid 2011 macbook pro 13". I installed it and since then i have had some problems.
first i installed the battery, it came with 67%, i let the MBP go all the way to the red and shut itself off, thinking this was the best way to calibrate it.
I plugged the mag safe charger in and let the computer charge
come back to it the next day and its at 0%, click on the battery icon and it says battery isnt charging (clearly is)
restart computer and it starts showing the charge, HOWEVER when i click on the battery icon it sill says not charging, but my light on charger is green, my battery icon has the charge look...
I have seen other threads where they recommend a SMC, i done one and it made my monitor go from the wallpaper to a white screen, i let it play out for 2 minutes before restarting it and it was normal....what does that mean?
im in desperate need of some help and piece of mind i didn't just spend top $$$ on a bum battery, and FYI im 2 hours from a apple store so i try to do all my mac work myself, or with this assistance of youtube.
Thanks

It says replace now, but I just bought the battery yesterday.

A1281 is the battery i got for my 15inch MBP. Is the battery life only 2 - 3 hours for a new battery on this device.

A1281 is the battery i got for my 15inch MBP. Is the battery life only 2 - 3 hours for a new battery on this device.
This is from Apple.
2 to 3 hours seems very low.
what is teh standard or advertised spec for a 15 inch Macbook Pro with this battery.
I would like to know so that i can return it if this is not normal.
Its expensive so comments would be appreciated.

I say it depends on your model? average usage is about 3-4 hours depending on what you use and how you use it. Adobe Flash player eats a lot of battery power so if you are on a web page and has flash player, likely that it's eating up battery because of it's power thirsty.
Also check your systems activity monitor. It could be possible that one of your program/apps did not close right and may be still running. So check for that and end the process if necessary.
If you have a backlight keyboard, in a broad daylight, it's not necessary to have it on.
I also suggest that you use it plugged in most of the time, and it's not going to hurt or damage the battery if you have it plugged in all the time. Only use on battery if you are going to places that has no access to the outlet. If you are at home, then keep it plugged in. Just keep in mind to fully drain the battery until it your MBP turns off on it's own. This is the calibration process so that you have the most accurate battery readings.
The standard for 2011 MBP is 7 hours on battery. Before that model is 10 hours, but i don't believe that previous models will last 10 hours. Last week I calibrated my battery readings from fully charged and it took 9 hours to completely drain out the battery (I have a 2011 model),
If you think it's not normal and that your battery doesn't meet your expectation then set up an appointment with the genius bar and have them test the battery. They will determine whether it is faulty or not.

New MBP, new battery~

Is it necessary to charge a new battery for at least 24 hrs for best performance in the future? Also, is it necessary to leave the MBP alone while charging for the first time?

Apple's directions state that you should use the computer on ac power for two hours after it shows full charge, and then disconnect from electricity and use it on battery until low battery warning, then save your data and close applications, use the computer until it goes to sleep, then either let it sleep for at least 5 hours (preferred) letting rest on battery (not ac til five hours) or shut it down and leave for at least 5 hours without electricity.
To use the computer after that, first reconnect to electricity, then open the computer to wake, or press the power button to wake, then wait for it to come out of hibernation, then use.
The initial use til charged can be divided but the rest needs to be done in good order.
Yes, the five hours rest before ac power is restored is essential.

13" MBP 2010 "Replace Now" battery condition, 1050 cycles, Will i have to pay for new battery?

I have a spring 2010 13' macbook pro. The problem with my macbook is that when i unplug the chager, after it says its fully charged, it automatically turns off. My batteries condition says to "Replace Now". I checked the battery cycle and its at 1050. i understand that my battery is supposed to last for 1000 cycles. Well my question is will i have to pay $129 for a new battery even though I still have a year left on my applecare?

Thanks Clinton (Birmingham, England?). I've actually only had this computer's battery on reserve twice since I bought it, but it generally runs down to 30 to 60% a couple of times a day, then I have plugged it in to top it off. I try to top it off before 30% because on this forum I've seen a couple of times that charging it from 50% twice, is much easier on the battery than charging it once from fully depleted.
So I guess if you charge it from say 70% to capacity three times this counts as one cycle?
Anyway, I'm not going to get obsessed about this. This is my third new or almost new MBP from my company, and I've never had the same one more than two years. I have had to replace batteries, but that is on old ones that have been handed down to my children.

MBP Freezes after new battery installed

I have an original MBP, and the replacement battery I got after the recall, wouldn't hold a charge and would shut my computer off by itself while still holding a charge.
The problem is this: I shelled out the $$ for a new battery, but the new battery makes my computer FREEZE forcing me to hard boot it. Every single time with the new battery in, after about 15 or 20 minutes of usage, I have to shut down and reboot.
Any ideas anybody? Thanks in advance!

They sent me a new battery and it does the exact same thing..
I took it to the apple store, the genius told me she couldn't do anything about it and told me to send it in to be diagnosed. :/ I'm going to try to reinstall the whole computer from a time machine backup and see if the new battery works, otherwise... I guess I'll have to return the battery for a refund!

Macbook OSX 10.5.8 - switches on, makes the usual noise - then screen goes black. Is it dead?! Can't try anything at all as it simply won't stay on. Had a new battery 4 months ago too.

My old macbook switches on briefly, makes the usual sound - then goes black and silent. It has occasionally switched itself off recently - but then come back on again after a moment a few presses of the power button. It has a new battery 4 months ago after the previous one expanded....Given I can't get it to turn on I can't try anything. Should I go straight to Apple Genius bar?

Hi. Are you running 10.5.8 and do you have the install disk? You could try a pram reset. Hold down Command/Option/P/R key on startup for three chimes and continue boot. If you have the install disk, you could boot to it then use the disk utilities off it to check or repair your drive and permissions. If you have a newer operating system you may have a recovery partition.

My macbook pro's screen constantly goes dim. I have set the energy saver settings for battery to 7 mins but it goes dim if the period of inactivity is less than 7 mins. Please help. MBP 13" OSX 10.6.8 (2011)

Doesn't sound like it. It sounds like you're being logged-off.
Does your Mac go through the complete Restart cycle -- black screen, gray and/or blue screen momentarily, startup chime, etc?
If you're not sure, do a Restart just to watch the process; the next time the problem occurs, see if it's the same.
You need to know which it is, as these will have very different causes, and different places to look for a solution.

MBP running slow after new battery is installed.

Hello everyone.
I just had a new battery installed in my Macbook Pro (from May 2008) a couple days ago and since then it runs extremely slow when I run more than one application. I have been trying to run Google Chrome and Microsoft Excel simultaneously and both lock up and shut down. I wasn't having issues before the new battery was installed.Is this problem related to the new battery or is something else going on?

Something else, I'd suppose - isn't that model a simple move two catches battery swap?
anyway - I'd try resetting the pram - http://support.apple.com/kb/ht1379
and smc - http://support.apple.com/kb/HT3964
and perhaps see if console has any clues for us - also see what activity monitor says for memory & cpu use when the slow-downs occur. Are other apps affected? if they shut down/crash - a report might show something relevant. You can also helpfully test in a New User Account

New 15-inch MBP (2008 MPB) battery drained to 84% in 15 mins. Help.

Hi there! I just popped in a brand new 15-inch MBP (square) battery into my 2008 MBP with Lion 10.7.4. It has drained to 84% in about 15 mintues. Is it a defective battery or a problem with caliberation? Thanks!!!

Calibrate it, and then you'll find out whether the problem is/was with the battery or its calibration.

MacBook goes dead as soon as power cord is unplugged..time for a new battery or other problem?

For months now my MacBook has been iffy with the battery percentage. It will show 2hours then within the next minute 25 min then 10 minutes then it shoots all the way up to 3 hours. Now it won't stay on unless the power cord is plugged in...and says "not charging" at the top of the screen. Am I in need of a new battery? Or is it something else? Have never had this problem before...my MacBook is approximately 3 years old...

You are posting in an iMac forum. I'd recommend re-posting in the MacBook forum.

Is it possible to use a new battery for a MBP 15" in a MacBook Pro (15-inch Early 2008) ?

i have an old MacBook Pro (15-inch Early 2008) and my battery is as close to dead as it can be. I was wondering if I could replace it for a new battery that works for the latest models.

No, that's a 60 watt. You need an 85 watt.
