Bought to replace a set that only lasted one year hope this set is much better than that the UPS takes eight of them

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.
