" ... How long it'll go I donno, we have a battery wall backup so this just has to last a few minutes for that to kick in. ... "
" ... Battery longevity seems fine too, no noticeable drop in life between a test of it brand new and a test of it months later. ... "
" ... Plugged it in waited overnight to charge plugged router and WIFI in it. ... "
" ... I was truly impressed by the features available on that backup unit, and the battery lasted for quite some time - longer than I expected its useable life. ... They don't draw a great deal of wattage, so there is minimal drain to the battery backup unit. ... We had a power failure a couple of weeks ago and the battery was able to maintain power for the full 45 minutes of the outage before power was restored. ... "
" ... It's a great little battery backup for your computer and monitor. ... The battery lasts about three years and I've bought several over the years. ... You could buy a replacement battery, but these cost about the same as a good battery, it's just easier to buy a whole new unit. ... "
" ... I use one of these battery backups for each computer in my house. ... The runtime is decent and the batteries last a long time. ... "
" ... Good battery life and easy to replace. ... "
" ... I tested it both out the box and after an 8 hour charge with no problems. ... One of the reasons I chose this model is because it appeared to have ample space for a battery. ... I'm sure that when it comes time to change the battery, there is plenty of room to put in a different sized unit. ... I wouldn't be at all surprised if a larger capacity battery would fit either. ...
