@mpm166 do a search be the standard number. Since we do not have the dimensions for your battery and do not know how many contacts it has, check something [https://www.amazon.com/Wasabi-Power-BTR-BL-5C-BL-5C-Battery/dp/B084WLXZX8/ref=sr_1_8?keywords=battery+gb+t18287-2000&qid=1664500103&qu=eyJxc2MiOiI0LjAyIiwicXNhIjoiMy40NCIsInFzcCI6IjMuMTQifQ%3D%3D&sr=8-8|like this] I am pretty convinced that MaxWest does not produce their own battery, so they will most likely be rebranded.
