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

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

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

 Althoughrechargeable batteries cost more than non-rechargeable batteries the overallcost or lifespan cost is much lower.

Here is some of our range of Rechargeable Batteries for Cordless Phones.

Lead Acid Battery

Below isa more detailed content about some of the terms used.

Lead–acidin 1859 the French physicist Gaston Planta invented the lead acid battery. Theyare 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 inapplications such as UPS (Uninterruptible Power Supplies) and Cell phonetowers.

Rechargeable Battery

Nickel–cadmiumuses Nickel metal Hydroxide. Invented in 1899 it has now been superseded byNiMh batteries. They were used in many portable devices and have the ability todischarge at a fast rate typically less than one hour. The major drawback isthe disposal of toxic Cadmium.

Nickel–metalhydride

Nickelmetal hydride batteries, also known as NiMH or Ni–MH,are rechargeable batteries of a later design then NiCad batteries. The chemicalreaction at the positive electrode is similar to that of the nickel–cadmiumcell (NiCd), they both use nickeloxide hydroxide (NiOOH). TheNominal cell voltage is 1.2 Volts and the Self-discharge rate is 13.9 to70.6% at room temperature. The charge/discharge efficiency is 66%–92%

Lithium-ion

Lithiumion batteries also known as Li-ion batteries use aninter-calated lithium compound as one electrode material thisis different when compared to the metallic lithium used innon-rechargeable lithium batteries. The cells have a highenergy density and a no memory effect and low self-discharge rate.

Lithium-ionpolymer

All lithiumpolymer batteries, AKA lithium-ion polymer batteries(abbreviated as LiPo, LIP, Li-poly, lithium-poly), is a rechargeablebattery of lithium-ion technology. They use a polymer electrolyte instead of aliquid electrolyte. They benefit from a high conductivity and high energydensity.
