Replacement battery for 15-BA11CL

[Mark160]

Hi,

I am using an HP Notebook product number X7T77UA.

I am experiencing issues with my laptop abrubtly shutting down while there is still a charge on the battery, so i have decided to replace the battery. The life of the battery is also too short now as it has aged. 

On the back of my battery it says to replace with HP part 807956-001.

My current battery is 3 cell and 10.95V.

The batteries i have found under that part number are all 4 cell 14.6V 2200mAh / 32Wh.

(This is the part number my battery says to replace itself with, even though it is different).

HP Shop doesn't offer this battery. It is out of stock and has been for weeks.

Can i upgrade my current battery from 10.95V to 14.6V or is that unsafe?

Either of these batteries is fine:

(21) Battery 

4-cell, 41-Whr, 2.8-Ah Li-ion battery 807957-001

3-cell, 31-Whr, 2.8-Ah Li-ion battery 807956-001

Given a choice you want the 4-cell. HP Shop will not carry a replacement battery on a laptop this long after end of production. However, there is a reliable and robust market for both genuine and aftermarket replacement batteries:

Hard to beat $20 shipping included. Do not worry about the different nominal voltages. 

Post back with any more questions and please accept as solution if this is the info you needed.
