Works out of the box!
Nice to get a battery with a full charge and have it work instantly. This battery was for my backup power supply and needed to work immediately.

Works great in my legacy UPS
This battery replaced the one in my very first (and oldest) UPS unit. It has kept my computer and monitors up a couple times already through brief power outages. No complaints here.
