I don’t know where you’re located but ifixit.com has Blade 15 batteries. They appear to sell the “Advanced” model batteries as 2018 Blade 15 and the “Base” model batteries as 2019 Blade 15. As far as I can tell, since 2018 the batteries in the Advanced/Base models has not changed, but I could be mistaken.

I just ordered one for my 2018 Advanced a few days ago, but it won’t arrive until later this week.

I just looked and the 2018 battery is compatible with my computer model! It looks great and I'm going to try replacing it myself, after all, the authorized Thunderbird store is just too far away from me. Thanks for the info!

Hi Kervin-Tsang,

You can PM me the serial number so I can validate its model and check our options for replacing the battery of your laptop. Thank you!

Hi @Razer.Zionzedd,

Could you provide me with a reliable source to buy a battery for my  Razer Blade 15 Advanced Mid 2019? 

Thanks!
