T400 Ultrabay Battery Issue

I just ordered and received a new Lenovo-branded Ultrabay slide-in battery for a T400.  It fits perfectly (appears to) but shows an error in the battery display and cannot even read the part number.


What came out was an FRU 42T4679  (10.8V, 2.7AH, 30WH).

What I received was an FRU 51J0508 (10.8V, 2.9AH, 32WH).

 

Does anyone know if this is likely just a bad battery, or an incompatible battery?


Thank you!

Re: T400 Ultrabay Battery Issue

not sure what is the battery cell manufacturer? check in your Thinkvantage Power Manager.

The Manager will not read anything.  It looks and feels TOTALLY like a Lenovo piece, and has the SKU noted above.  The Manager simply posts "ERROR' and does not read a manufacturer or anything else.  

 

Thanks.

I think you need to talk to the seller and ask for an exchange or return.

Re: T400 Ultrabay Battery Issue

Thanks for your help.  Strangely, it has appeared to start working and charging this morning.  One of the mysteries of life....
