Questions about this item

How long will the 12V lead-acid cells in this #35 cartridge hold a full charge under continuous load?

The 12V lead-acid chemistry in cartridge #35 is rated for 100% compatibility with the APC BE350U, so its runtime limit matches the UPS design specifications for that model.

Does the 2-pack of #35 cartridges generate noticeable heat or fan noise when the BE350U runs all day?

These sealed 12V lead-acid cartridges operate without fans; heat output stays within the BE350U's normal charging envelope, adding no audible noise beyond the UPS itself.
