Three New Laptop Batteries failed on EliteBook 1040 G4

[hustle1]

Hello All,

I ordered a replacement battery for my 1040 G4 but all 3 new batteries report this error or Blown fuse.

 

I ordered the batteries from iFixit and from the first battery I installed had this error and it refused to calibarite on bios then would randomly Hard shut down whether plugged in or on battery.

The computer would also run very very slow, run on AC only and refuse to charge the battery. Only charge if I reset the battery by holding down Power button.

I reached out to iFixit and quickly got a replacement 2nd battery still same error.

Got another replacement 3rd  battery same error.

Only original battery is working, which I realized HP Support assistant/hardware diagnsotics was reporting as weak 27% capacity left but that was with the maximize battery life setting, with that off it jumps to 70% capacity but out of nowhere reports critical battery failure on bios but next day its okay.

All hardware diagnostics show no error with original battery and works fine even holds charge for 3 hrs. 

The weak capacity error on HP support Assintant made me order the replacement  but as you can see below orginal battery is now normal.

I have updated to the latest BIOS just last week. As you can see and using the orignal battery now:
