Questions about this item

Should I choose the four-battery kit or a single 12V9A unit?

The kit contains four 12V9A batteries wired together to match the original cartridge voltage and runtime; a single unit would not provide the required series string for the UPS.

What does the 12V9A rating deliver once installed in my UPS?

Each 12V9A block supplies 9 ampere-hours at 12 volts, and the four-unit series string restores the factory runtime and load capacity the UPS was designed for.
