Decent quality battery and seems compatible with Lenovo L430 on newest BIOS
My L430 wouldn't charge the spare 55+ battery I had in my drawer so I I was a bit worried about buying 'compatible' batteries so ordered this apparently genuine +70 one which arrived well packed and next day. When installed the BIOS was happy and started charging it. When full I tested for 1 hour 20 mins and it still had some % so was as described.
The long number on the battery I received seemed to contain 45N1000 so may be slightly older than a 1001 but I am happy with it's performance and compatibility with the L430.
