  • CompatibilityFits: APC BE350U-CN
  • Compatible replacement for APC BE350U-CN UPS

  • Two batteries included for complete unit refresh
  • 100% compatibility guaranteed with original equipment specifications

APC BE350U-CN Compatible Replacement

This two-pack of PowerWarehouse 12 V 35 Ah lead-acid cartridges is built as a direct drop-in for the APC BE350U-CN uninterruptible power supply. Each unit is guaranteed 100 % compatible with the original equipment and carries a one-year replacement warranty. The pair restores backup runtime for home-office networking gear, entry-level servers or point-of-sale terminals that rely on the BE350U-CN chassis. Buyers needing higher-capacity packs or lithium chemistry should look elsewhere.

Normal-Use Thermals Noise and Power Draw

Sealed lead-acid cells run passively with no fans, so acoustic output is effectively zero in typical office ambient temperatures. Self-discharge is low, allowing the battery to hold charge for months between utility events without measurable parasitic draw. During a discharge cycle the pack delivers its rated 35 Ah at 12 V with minimal voltage sag, and recharge current follows the UPS’s built-in taper profile without generating excess heat. No active cooling or special ventilation is required beyond the enclosure’s existing airflow.

Questions about this item

How do I install the PowerWarehouse 2XRBC35SLA354 battery cartridge into my APC BE350U-CN UPS, and what step is often missed?

Open the battery door, disconnect the old cartridge, insert the new 12V 354 cartridge, reconnect the terminals, and close the door; the step often missed is ensuring the connector clicks fully into place.

What maintenance will the PowerWarehouse 2XRBC35SLA354 batteries need, and when should I plan a replacement?

These sealed lead-acid batteries require no routine maintenance; plan replacement after 3 to 5 years or when runtime drops below 100% of the original 350 VA load capacity.
