PowerWarehouse 12 V 5 Ah UPS Battery

This sealed lead-acid battery replaces the RBC43 cartridge in compatible APC uninterruptible power supplies. It delivers 12 volts and 5 ampere-hours of maintenance-free backup power for server and network equipment. The unit arrives new and ready to install without additional preparation. Builders who need a different voltage or capacity will need another model.

Thermals Noise and Power Draw

The battery operates silently because it has no moving parts or cooling fans. Heat output is negligible during normal float charging and brief discharge cycles. Power draw is limited to the charger current required to maintain full capacity. Installations that demand active cooling or audible alerts must rely on the host UPS electronics.
