Act of empowering an herb, stone or other magickal object with one's own energies directed towards a magickal purpose.
"charging" a battery is a misnomer for "energising" it. It means putting energy into the battery by forcing a current through the battery, against the battery's emf. The term charging is misleading because the total charge in the battery is always the same; although mobile charge passes through the battery during "charging" and "discharging" what matters is the state of the chemicals in the battery and the energy that you can get from it.
The procedure to convert the chemicals in a storage battery to their original conditions by passing a higher voltage electrical current through the plates and electrolyte. Charging reverses the discharge of a battery and attempts to restore it to a useful state of charge.
