Rechargeable Batteries

Rechargeable batteries typically initially cost more than disposable batteries, but have a much lower total cost of ownership and environmental impact, as they can be recharged inexpensively many times before they need replacing. Some rechargeable battery types are available in the same sizes and voltages as disposable types, and can be used interchangeably with them.

Rechargeable Battery

Rechargeable batteries are also called or known as accumulators, storage battery and secondary cell. They differ from primary batteries or cells because they can be re-charged. This means that they have a much lower environmental impact as for example one AAA NiMH rechargeable battery or cell can be re-charged up to 1000 times. So you would have to use 1000 primary cells in its place.

There are different technologies or chemistry types that are suited to specific applications. They range in shape and size from a tiny button cell to a large megawatt system used in industrial applications. There are also many combinations of electrode materials and electrolytes these include lead acid, nickel cadmium (Ni-cad), nickel-metal hydride (NiMH), lithium-ion (Li-ion) and lithium-ion polymer (Li-ion polymer).

 Although rechargeable batteries cost more than non-rechargeable batteries the overall cost or lifespan cost is much lower.

Lead Acid Battery

Below is a more detailed content about some of the terms used.

Lead–acid in 1859 the French physicist Gaston Planta invented the lead acid battery. They are relativity cheap to manufacture and can supply very high current surges. This is why they are popular in the automobile industry. They are also used in applications such as UPS (Uninterruptible Power Supplies) and Cell phone towers.

Rechargeable Battery

Nickel–cadmium uses Nickel metal Hydroxide. Invented in 1899 it has now been superseded by NiMh batteries. They were used in many portable devices and have the ability to discharge at a fast rate typically less than one hour. The major drawback is the disposal of toxic Cadmium.

Nickel–metal hydride

Nickel metal hydride batteries, also known as NiMH or Ni–MH, are rechargeable batteries of a later design then NiCad batteries. The chemical reaction at the positive electrode is similar to that of the nickel–cadmium cell (NiCd), they both use nickeloxide hydroxide (NiOOH). The Nominal cell voltage is 1.2 Volts and the Self-discharge rate is 13.9 to 70.6% at room temperature. The charge/discharge efficiency is 66%–92%


Lithium ion batteries also known as Li-ion batteries use an inter-calated lithium compound as one electrode material this is different when compared to the metallic lithium used in non-rechargeable lithium batteries. The cells have a high energy density and a no memory effect and low self-discharge rate.

Lithium-ion polymer

All lithium polymer batteries, AKA lithium-ion polymer batteries (abbreviated as LiPo, LIP, Li-poly, lithium-poly), is a rechargeable battery of lithium-ion technology. They use a polymer electrolyte instead of a liquid electrolyte. They benefit from a high conductivity and high energy density.
