Unless there's a longer string (of which the Dell part number is a part), it's almost certainly not an original Dell battery.

Hi. Thank u so much for reply.

My new Battery No. is  CN-04YRJH-48630-535-O01M-A03...........1. so is it original?

while of old one is

                                        KR-08NH55-71766-16G-EEP3-A00...........2. and is we can use 04YRJH in place of 08NH55.

Hi Shuka,

The part number 4YRJH is a valid battery for a N4110 system, so you can use it as a replacement for your original 8NH55 battery.

once again thanks.

I have one more doubt..........

As soon as I place my battery and turn on the system, it was already charged upto 40%, I need not to charged it at all.

Is new batteries are also charged before,,,,,,,,??is it somewhat doubtful

my dell battery part no. or qr scan code is KR-84DMMG-71769-...........2      is it original or not sir??
