What rechargeable battery is:

• A rechargeable battery or storage battery is a group of one or more electrochemical cells. They are known as secondary cells because their electrochemical reactions are electrically reversible Rechargeable batteries come in many different shapes and sizes, ranging anything from a button cell to megawatt systems connected to stabilize an electrical distribution network. Several different combinations of chemicals are commonly used, including: lead-acid, nickel cadmium (NiCd), nickel metal hydride (NiMH), lithium ion (Li-ion), and lithium ion polymer (Li-ion polymer)
• Rechargeable batteries have lower total cost of use and environmental impact than disposable batteries. Some rechargeable battery types are available in the same sizes as disposable types. Rechargeable batteries have higher initial cost, but can be recharged very cheaply and used many times

Common rechargeable battery types:

• Graph of mass and volume energy densities of several secondary cells

Nickel-cadmium battery (NiCd):

• Created by Waldemar Jungner of Sweden in 1899, based on Thomas Edison's first alkaline battery[citation needed]. Using nickel oxide hydroxide and metallic cadmium as electrodes. Cadmium is a toxic element, and was banned for most uses by the European Union in 2004. Nickel-cadmium batteries have been almost completely superseded by nickel-metal hydride (NiMH) batteries

Nickel-metal hydride battery (NiMH):

• First commercial types were available in 1989.[20] These are now a common consumer and industrial type. The battery has a hydrogen-absorbing alloy for the negative electrode instead of cadmium

Lithium-ion battery:

• The technology behind lithium-ion battery has not yet fully reached maturity. However, the batteries are the type of choice in many consumer electronics and have one of the best energy-to-mass ratios and a very slow loss of charge when not in use

Lithium-ion polymer battery:

• These batteries are light in weight and can be made in any shape desired

Battery Capacity:

• Look for batteries with a higher milliampere hour (mAh) rating. This refers to the amount of electricity delivered at any given moment. Electronic devices can handle a range of mAh without damaging the device. So as the rechargeable batteries begin to lose power, they do no damage to the device. Batteries with a higher mAh may look exactly like a battery with a lower mAh but typically they cost more.

Battery Chargers:

• Buy the battery charger that suits your needs. In some instances you can purchase the charger and batteries as a package deal, but if you want your battery charger to maintain your rechargeable batteries properly, you may need to pay more for special features.
• Look for a battery charger that recharges a variety of battery sizes. Select a unit that has a reconditioning cycle. This keeps you from overcharging your batteries. Some models do this automatically while others have a switch you must flip to go into reconditioning mode

Usage and applications:

• Rechargeable batteries are used for automobile starters, portable consumer devices, light vehicles (such as motorized wheelchairs, golf carts, electric bicycles, and electric forklifts), tools, and uninterruptible power supplies. Emerging applications in hybrid electric vehicles and electric vehicles are driving the technology to reduce cost and weight and increase lifetime.[1]
• Normally, new rechargeable batteries have to be charged before use; newer low self-discharge batteries hold their charge for many months, and are supplied charged to about 70% of their rated capacity.
• Grid energy storage applications use rechargeable batteries for load leveling, where they store electric energy for use during peak load periods, and for renewable energy uses, such as storing power generated from photovoltaic arrays during the day to be used at night. By charging batteries during periods of low demand and returning energy to the grid during periods of high electrical demand, load-leveling helps eliminate the need for expensive peaking power plants and helps amortize the cost of generators over more hours of operation.
• The US National Electrical Manufacturers Association has estimated that U.S. demand for rechargeable batteries is growing twice as fast as demand for nonrechargeables

Warnings:

• Do use the specialized accesory to recharge
• The input voltage of any appliance must be in the range of the output of the battery, otherwise it can do harm to the applince
• To avoid the decending capacity, the battery must not be put away over 1 year
• Away from high temperature, and kept in cool dry place

Package Included:

• 2 x Rechargeable Batteries
