There is always a quantity of electric current (usually in mAh) written in all types of Rechargeable batteries. How does it relate to the 'charging time' and the Charger's power (charger's power is also defined with mAh in most cases) ?
How this quantity of electric current (usually in mAh) written in all types of Rechargeable batteries affects the performances of corresponding electronic devices, eg. if I use Rechargeable batteries with same 'volt' but lower/higher 'mAh' in a cordless phone - then what wrong (if any) will happen ?
