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 Nickel-cadmium batteries have been almost completely superseded by nickel-metal hydride (NiMH) batteries.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.

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
