Your PSCRT3000, PSCERT2000, PSCERT3000, or PSRTBB12 is the last line of defence before a power cut takes out the whole floor. And it's running on degraded cells. Cartridge #6 is the PowerShield build for all four of those units. Six 12V 9Ah cells in one clamshell pack. Pull the old cartridge, seat this one, close it. Same footprint, same terminals, same runtime you had when it was new. If that UPS is protecting a clinic's records, a school's network, or a small office's entire day, you don't want to be guessing at cell counts from a marketplace listing. Add to cart
