Is there anyway to boot kindle without battery or get a cheap battery

i have this old kindle, but no battery, i was wondering if there is anyway i can boot it without having a battery installed, i do have a 3.7 volt battery that does supply enough energy for it but the kindle wont boot as it doesn't think its a amazon original battery, i dont want to spend the money on a battery as those can cost up to $20+. thanks (if u got anymore questions about it i would be happy to answer)
