RefurbUPS Interstate BSL1075 12V 7A UPS replacement battery

Interstate BSL1075 compatible replacement

This 12V 7A sealed lead-acid battery serves as a direct replacement cartridge for compatible UPS units. It is intended for users who need to restore runtime to an existing uninterruptible power supply. The kit includes a single high-rate discharge cell and installation instructions. Buyers whose UPS requires a different voltage or capacity should verify specifications before purchasing.

SLA chemistry and form-factor limits

Sealed lead-acid technology delivers reliable standby power but has a finite cycle life and gradual capacity loss over time. Performance depends on the UPS charging circuit and ambient temperature; extreme heat or deep discharges shorten service intervals. The battery must physically match the original cartridge dimensions and terminal layout for a proper fit. Systems needing lithium-ion energy density or faster recharge rates cannot use this chemistry.

12V 7A capacity and runtime envelope

The 12V 7A rating supports typical desktop or small-server UPS loads for a limited backup window during mains failure. Runtime scales with the connected load; heavier draws exhaust the reserve quickly while lighter loads extend it. The cell is designed for float standby use rather than frequent deep cycling. Installations requiring extended autonomy or multiple battery strings will need additional capacity beyond this single cartridge.
