For real?
The black box with two terminals is a 12V battery, and it looks like a lead-acid battery. Is it a DELL? Is it an IBM? Is it an HP? No, it is a Google. That’s right people, it’s a unit of many Google’s server inside its data center containers. It’s a 2U thick server, with a Gigabyte mainboard holding 2 CPUs, 2 hard disks, and 8 pieces of RAM.
It’s not really battery powered, but the battery kicks in once the main power is lost. This effectively eliminates the need for more expensive and space consuming giant UPS’s (uninterruptible power supplies) which are batteries anyway. Is this a better solution? You be the judge.
If you ask me, I’d like to have one of those Magnetek power supply unit to install on my PC. The battery can nicely fit in a tower casing, much better than having separate UPS units. However I think the mainboard itself must be custom because the 12V to 5V conversion takes place there. The power supply unit only outputs 12V (approximately 13.65V).
However I can’t find any info on how long can the battery can actually supply power.
