Looking for a Small Battery Backup to power up a router and a small home switch just to hold until building power plant goes online when theres is outage. it takes like 10 seconds the power to come back, but the router takes ages to restore service. The problem is all the gear is on a cabinet with a dept of 4 inches.
So yeah i'm looking for a battery back-ups that is less than 4 inches Width to get it in there. The closes UPS i found is the APC BN450M but specs on width is 4.13 inches. Any recommendation of a battery i can use for this case? thanks!
