Battery for a np9377-s or p377-sm

Well after stupidly leaving my laptop plugged in all the time the battery went bad now I get about a minute or two of usage. So I am looking for a gently used or new battery if anyone has one please hit me up, my ol p377-sm in 2x sli are still beast mode. I still need to install the 120hz display I have seperate, I might just sell it since its hard to find I am not sure what they are going for these days but thats enough rambling I am here about my battery. Thanks for your time take care and God Bless!
