As the word itself states, a uplive recharge battery can be recharged to be used multiple times. They repeat consecutive cycles of charge and discharge which are based on the reversibility of the chemical reactions of the batteries’ electrolytic components. For the cycle of charge and discharge to be initiated, a calculated amount of electric charge is passed through the battery using a charger device. This current causes the reversible reactions of the electrolytic components. However, they can only be recharged and used multiple times until the battery chemicals gets too depleted to produce discharge energy. Depending on the type of battery, there are also different types of chargers.
Portable electronic devices like cameras or mp3 players are mostly what rechargeable batteries are used for. The size also depends on its capacity. They have the following measurements: 44.5 mm in length, 10.5 mm in diameter, and around 11.5 g in weight.
They can be of the rechargeable or standard non-rechargeable type. Alkaline batteries are available in both types, too. An alkaline rechargeable battery has an average electric yield of 1.5 volts and 900-1,155 miliampere-hours(mA-h) or 3240-4158 coulombs. You can also get a similar output from a rechargeable NiMH (Nickel Metal Hydride) battery; this can store a current up to 1000 mA-h and have an output of 1.2 volts.
Other common names for batteries are Micro, Microlight, LR03 (for alkaline), R03 (for carbon zinc ), and FR03 (for Li-Fes2); the last three terms are designated and used by the International Electrotechnical Commission, or IEC. The battery is of cylindrical shape with the nub end as the +ve terminal and the flat end as the -ve terminal. When several are connected in a row, it creates a battery system for the portable device.
Because NiMH rechargeable batteries have higher capacities, they are more popular among consumers. Additionally, NiMH batteries do not suffer from memory effects the way NiCd, or Nickel-Cadmium, batteries do. But using these type of batteries has a disadvantage, too. They have a high self-discharge rate which causes them to go dead after a few months whether or not they have been used. The active electrolytes in the NiMH type have a high rate of spontaneously transitioning to a discharged state even without an electric charge passing through them. This is why they are not commonly used in emergency devices like smoke detectors and emergency flashlights.
