Macbook Battery Issue?

Hi

With regard to battery power on my Macbook 5.1 OS X Leopard 10.5 I'm only getting 10min of battery time when not connected to a power chord. Even though battery status confirms full, the Mac automatically shuts down at 85%. In system preferences battery settings are at computer sleep 20min and display sleep 15min, but this occurs only when the Mac is inactive.

Why isn't the Mac consuming it's full battery time of say 2hrs.

Did you ever calibrate it?

Try resetting the SMC. Also, calibrate your battery using the instructions in the CALIBRATION section of the following link.

The link below should answer most, if not all, of your battery/charging questions. If you haven't already done so, I highly recommend you take the time to read it.

Read the instructions, it confirms,

Quote:
With the computer still on, disconnect the power adapter and continue to use your computer.

When you see the low battery warning, save your work and close all applications. Keep your computer turned on until it goes to sleep.
This is totally not possible as when i disconnect the PA there is no time for a battery warning as the Mac shuts down automatically after 10 min.

It's been suggested my Mac battery is dead and will need to replace it. I purchased the macbook in 2009 and have almost certainly always used it vie the power adapter not battery back up. Given this info would anyone else recommend a battery replacement ?

You have given conflicting information about your MacBook. The MacBook 5,1 is the aluminum model initially released in October, 2008. You claim you bought yours in 2005, which isn't possible, since the first MacBook model was released in May, 2006. Enter your serial number here to find accurate specs for your model.

You can also find specs on all Apple products:
I wouldn't trust or recommend any non-Apple battery, due to the number of problems reported with "knockoff" batteries. Also, there is no assurance that knockoff batteries have the same charging technology that Apple uses, involving the battery, the MagSafe adapter and the Mac's logic board.

Sounds like you do need a new battery.

You might want to check this, if you haven't already. It'll tell you what state your battery is in.

It's not worth risking a $2-3000 computer on a knockoff battery, just to save a few bucks.

I would prefer to go with GGJstudios recommendation by purchasing the original Apple battery for the macbook as opposed to replacing it and installing a third party battery. Just gives peace of mind in knowing you've got the real thing.

Is it still possible to purchase an internal battery for a 13-inch aluminum 2009 Macbook?

Sure. Just take it to Apple and they will replace it for you.

Assuming that is the new battery, it is not detected. Have you tried resetting SMC? Battery might be bad or then the battery connector in the machine is bad. I have owned Macbook and disassembled it but I cannot remember whether or not the battery connector was directly soldered to the motherboard or if it was replaceable, like it is in my Macbook Pro.

Hold up. I see your cycle count is extremely low. If you nag the guy at the apple store enough he'll probably replace your battery for free.
