Won't fix problem of loss of power, but you can at least get back to work. A car battery isn't designed to be run dead, a deep cycle is for things like boat trolling motors and will not get quickly destroyed like a car battery is now designed. Years ago I had an electric bill that took me months to pay and I did just this for six months, charging it at work. Don't use a surge suppresor with this set up!
There is a way to set things up to make a clean switchover that is SAFE with the power on then cutting out. Maybe an old UPC with a bad battery and use that with the bigger battery? Solar power also has something for that too. You can usually find used stuff like that either free or cheap. You'll get hours of power with a deep cycle. But if you want a clean and safe switch without losing power, make sure your setup is safe. You can probably google a good method. A plus with the inverter is that you can also run some lights/TV/etc charge cell phone during the outage. They also shut off before running the battery dead. Ideally, get a UPC to shutdown with and and the battery plus inverter to start back up with. Chris Bennett
