Posted: 12:56 - 22 Oct 2018 Post subject: Battery capacities for a UPS, anyone? |
|
|
I have a Uninterruptible Power Supply for my computer equipment, and unfortunately today it started screaming at me that its battery had failed so I'm trying to source a replacement. Does anybody know anything about this stuff?
The device is an APS Back-UPS ES 550. The manual is here, and says that its battery capacity is 550VA/330W.
I've found a replacement battery at https://www.tayna.co.uk/ups-batteries/powerline/pu7/; which looks spot on; however it describes the capacity as 7 Ah. My tiny and ageing brain is struggling to work out if this is consistent - I'm trying to remember my O-level physics and equating 7 amp-hours with 330 watts (joules/second). Does that make any sense? Aren't these fundamentally different quantities?
Can anyone shed any light as to whether this is the correct battery for me? ____________________ KC100->CB100N->CB250RS--------->DL650AL2->R1200RS->R1250RS |
