Two-pack replacement for APC BK500M

This twin-pack supplies two 12 V sealed lead-acid cartridges built to fit the APC BK500M uninterruptible power supply. Each unit is tested for 100 % compatibility with the original equipment so the UPS recognises the battery immediately. The pack restores backup runtime for home-office routers, modems and entry-level workstations. Buyers who need higher-capacity cells or lithium chemistry will not find those options here.

Sustained discharge on sealed lead-acid chemistry

Under continuous load the 12 V cells deliver steady voltage until the UPS initiates its low-battery shutdown sequence. The sealed construction prevents electrolyte loss during repeated deep-discharge cycles typical of mains outages. Internal resistance remains stable across the service life, so recharge times stay predictable after each event. Installations that demand hot-swappable modules or extended runtime beyond the BK500M chassis limits require a different UPS platform.

Questions about this item

How much heat does the 12 V lead-acid cartridge produce during continuous UPS operation?

The sealed 12 V lead-acid cartridge generates minimal heat under normal load; typical warm-up stays well within the UPS enclosure's design limits.

What existing UPS hardware is required for these replacement cartridges to function?

They are direct replacements for the APC BK500M UPS, so that unit must already be installed and operational.
