Compatible 12 V Lead-Acid Pair

This two-pack supplies direct-fit 12 V lead-acid cartridges built to replace the APC BP420S unit. Each battery is manufactured to match the original equipment specifications so the UPS recognises them without configuration. The pair suits administrators who maintain rack-mounted or tower UPS units that require the BP420S form factor.

Steady Float-Charge Operation

Under continuous float charge the cells maintain stable voltage and low self-discharge, supporting the UPS through extended mains outages. The lead-acid chemistry tolerates the trickle-current regime typical of standby power systems without rapid capacity fade. Buyers needing lithium energy density or hot-swappable modules should select a different technology.

  • Premium 12 V lead-acid cells deliver reliable backup power
  • 100 % compatible with APC BP420S cartridge #2
  • Two-battery pack restores full UPS runtime in one step
