Interstate BSL1104 Compatible UPS Battery

This replacement battery cartridge contains one 12V 12A sealed lead-acid unit built for high-rate discharge. It fits UPS systems that specify the BSL1104 form factor and voltage. The kit includes installation instructions for straightforward replacement. Buyers needing a different voltage or capacity should verify their UPS requirements before ordering.

Sealed lead-acid chemistry and 12V 12A rating

The battery uses sealed lead-acid technology rated at 12 volts and 12 amps for high-rate discharge applications. Runtime and load support depend on the specific UPS model and its power draw. No other chemistry, voltage or capacity is provided in this cartridge. Systems requiring lithium-ion or alternative chemistries are not compatible.

Single 12V 12A SLA battery cartridge

The package supplies exactly one 12V 12A sealed lead-acid battery identified as Interstate BSL1104 compatible. This single unit determines whether the kit matches the UPS slot and electrical specification. Multi-battery packs or higher-capacity units are not included. Confirm the UPS manual calls for a single BSL1104 cell before purchase.

Questions about this item

Which capacity should I select for the BSL1104 kit?

The kit contains a single 12V 12A high-rate discharge SLA battery, so there is no capacity choice to make.

What does the 12A rating mean once the battery is installed in my UPS?

It indicates the amp-hour capacity, giving you a 12 Ah reserve for high-rate discharge during power loss.

What interface or standard does the BSL1104 use, and what does it limit?

The battery connects via standard UPS terminal posts; the 12 V / 12 A rating caps the available backup runtime and peak discharge current.
