WhatsAppBattery energy is sometimes referred as battery capacity, which is not very accurate. To clarify things, there are two types of "battery capacities": battery current capacity, also called battery capacity, measured in amperes-hour [Ah] battery energy capacity, also called battery energy, measured in joules [J], watts-hour [Wh] or kilowatts-hour [kWh]
WhatsApp23 · Factor1 - Battery capacity Battery capacity (AH), represents the total amount of electrical energy a battery can store and deliver under specified conditions. The charging time is proportional to the battery capacity.Larger capacity batteries store more energy, leading to longer charging times when the charging current is kept constant.
