Replacement battery pack for Belkin F6C425-SER

This two-pack supplies 12 V lead-acid cells built to match the original cartridge #276 specification. It is intended for owners of a Belkin F6C425-SER UPS who need to restore backup runtime after the factory batteries have aged. The pack is not for users whose UPS requires a different voltage, form factor or cartridge number.

Practical limits of the 12 V lead-acid interface

Lead-acid chemistry delivers reliable standby power but offers lower energy density than newer chemistries, so runtime per kilogram is modest. Capacity fades with each deep discharge cycle and with elevated ambient temperature, meaning the pack will eventually require another replacement. The 100 % compatibility claim covers electrical fit only; it does not extend runtime beyond the UPS design limits.
