Already installed. Works great. Fully charged. Manufacturer said battery could not be replaced on my PSX1004ln. Actually, it took a little time, but it was quite easy.

My last Mighty Max lasted 5+ years in my Honda generator. Still cranked it over but was slowing down. New one starts fast, now ready for 2026 hurricane season.
