Q: my macbook pro 13 mid 2009 doesn't recognise the battery

You may have to use the original installation disk with the AHT instructions on it.
Note that an error free AHT is not definitive.
Ciao.

I run AHT (cmd + D) and an error 4SNS/1/40000000 TB3T-128.000 (i think that's the right number)
After a Google search this is an error on the battery temperature sensor!!
That is correct, it is a battery sensor error. Make plans for an appointment at an Apple store genius bar. This is a hardware issue that only they can rectify.
Ciao.

Jan 27, 2015 8:42 AMby Allan Jones,Your battery report looks very odd, especially in what is missing from it. Is this the original battery or is it a replacement battery? If a replacement, from where di you get it?
Here is what the first section of the "Power" screen looks like on my 2013 13-inch MBP with its original battery:
You report has nothing above "Charge information" section, other missing items, and a lot of zero values. I doubt a failed battery temp sensor would wipe out all those values. That is what makes me ask if is this a replacement--I'm thinking counterfeit.

Jan 27, 2015 11:17 AMby djg-macris,I had problem with the original battery,it had been swelled…then i removed it from MBP while i had ordered the new one.
I was running MBP without battery installed! Without battery installed i ran this: MacBook Pro SMC Firmware Update 1.5
After that i installed the new battery and when i was opening the "power" section in System Information there was a message: an error occurred (something like that)
For 15-20 days there was a battery icon in menu bar but MBP didn't charge the battery,when i was unplugging the magsafe power adapter the system was going to sleep!!
Now there is an X in the battery icon in menu and when i unplug the adapter system is shutting down hard!
Here is the battery i installed:

Jan 27, 2015 11:39 AMby spudnuty,Have you tried resetting PRAM and SMC?
Reset SMC

Reset NVRAM

Otherwise you might try doing a hard reset of SMC. Follow the instructions for "a battery you can remove" You'll have to open up the MBP and remove the battery.
Otherwise maybe bad battery. Greek?
