Now let us start discussion about energy stored in the magnetic field due to permanent magnet. Total flux flowing through the magnet cross-sectional area A is φ. Then we can write that φ = B.A, where B is the flux density. Now this flux φ is of two types, (a) φ r this is remanent flux of the magnet and (b) φ d this is demagnetizing flux.

The lead acid batteries are also used to store backup power. This can be seen in Fig. 8. However, lead acid batteries are often repeatedly recycled and are currently the leading consumer product. Also, the lead acid batteries can offer short life
Charge isn''t stored as charge in a battery. A chemical reaction generates the charge. This would be the same as converting the light to something else, storing that something else then regenerating the light when needed. We can even "store" a magnetic field in a magnet. Not the same thing, as we are not storing magnetic charge in a magnet.
DOE ExplainsBatteries. Batteries and similar devices accept, store, and release electricity on demand. Batteries use chemistry, in the form of chemical potential, to store energy, just like many other everyday energy sources. For example, logs and oxygen both store energy in their chemical bonds until burning converts some of that chemical
