    I have many devices using APC Battery Back-up Systems. This new generation has improved control to extend power to critical devices. The manual estimates 5.9 hours power supplied to a wireless router. I recommend battery backups to protect data and maintain internet connections during long power outages.

    It's hard to get excited about a battery backup unit. This is a replacement for a 6+year old unit that was beeping either because the battery died or the unit just reached the end of its life. Just decided it was time for a replacement. It's connected to an iMac and works perfectly. Only complaint is that the power cord is too short.

    I bought this one a month ago (April ‘20), to replace one I’d purchased nearly 20 years ago that a new battery couldn’t fix. Installation was easy and it has quietly done its job ever since. That’s what I expect and I’m completely satisfied! Thanks for asking!
