Direct OEM Replacement

The BatteryJack HC1217W is a sealed 12V 5AH AGM battery built as a 100% compatible swap for APC RBC10 and RBC21 cartridges. It fits the Back-UPS Office BF250, BF280, BF350, BF400, BF500 and Belkin F5C500, F6C600, F6C650 units without modification. Maintenance-free construction means no fluid checks are ever required.

Upgrade From Failed Cells

This unit replaces a depleted original battery when runtime has fallen below useful levels or the UPS reports a replacement warning. The jump is worth it when the existing pack no longer holds charge through a typical outage or shows physical swelling. Advanced AGM chemistry restores the original 4-7 year design life in a single step.

Drop-In Build Fit

Recessed terminals measuring 5.51 x 1.89 x 4.0 inches align with the factory battery tray and existing wiring harnesses. No adapter cables, rail kits or firmware updates are needed. The sealed case eliminates ventilation constraints, freeing rack space for additional equipment while the two-year warranty covers the replacement cycle.

Questions about this item

Will the 5.51" × 1.89" × 4.0" case slide into the battery compartment of my APC BackUPS Office BF500?

Yes, the PowerStar HC1217W matches the 12 V 5 AH form factor used by the BF500 and the listed APC RBC10 and RBC21 packs.

Do I need any tools or soldering to swap the old pack for this one?

The battery uses recessed terminals that plug straight into the UPS harness; just disconnect the old pack, connect the new one and secure the cover.

When should I plan to replace this AGM cell again?

The manufacturer rates the service life at 4-7 years; expect to swap it once the runtime drops noticeably or after roughly five years in standby use.
