Brake light symbol being on is usually an indication of low brake fluid and or low brake pads. When the brake pistons are further out the fluid in the brake reservoir goes down, this is usually a slow process. You can top the master cylinder up if that's the case, but do a brake inspection and determine how much brake material is left, you might be needing a brake service, pads, resurfacing or replacing the rotors etc. When you put new pads in the brake caliper pistons will go inwards pushing fluid back to the master cylinder.
As far as the battery is concerned if it is the original it may be on it's last legs. You can try disconnecting it and hooking it up to a low amperage charger to bring it back to life and wait and see if the light goes out. If after a few days, weeks, months, the battery light comes back on, I'd consider changing the battery.
