It has saved me during power outages, sump pump failures, more than once.

Take a serious look at this option. No pump to fail, no battery to die. I believe most city water pumping stations have generator backups and can't ever recall losing water pressure. You can spend a lot more money on far less reliable options.

This is where you should start. When we purchased our house nine years ago there was a legitimate flow of water into the sump pump hole during a heavy rain, and the pump would run every 5 minutes or so. I did replace the pump just for peace of mind, but then I also brought in a bunch of dirt to insure a proper grade away from the foundation, buried my downspouts to tie into my back yard french drain system, extended the remaining downspouts away from the foundation, and tied the sump pump drain into the back yard french drains. These relatively simply fixes have yielded a sump pump that almost never runs, even in a very heavy rain.
