I don't think you need a battery backup unless you intent to use your equipment during power outages. A surge protector should be enough; also, no matter which or what kind of device you have... there is no 100% guarantee it will protect your devices, but it can reduce the chances of damage.
I was unlucky to have my house struck by lighting (no external damage though) and all the stereo equipment along with many other devices were fried. Dedicated power circuits, good APC surge protectors etc. Freak accident for sure.
