Nickel cadmium battery is an early marker rechargeable battery, for “Ni – CD,” he monomer voltage 1.2 V, common have 7 (AAA), 5 (AA), 1, 2, and industrial models. He is relatively low self-discharge nimh batteries, resistance is small, the price is relatively cheap, Defect is easy produce memory effects. Battery capacity with the most widely used in the 5th (AA) battery, for example, single battery capacity can be 500MAH 850MHA – 600-700MAH mainstream, for the product.
Ni-mh battery is a new kind of high capacity rechargeable batteries, marked “Ni fd-mh”, many of his characteristics and nickel cadmium battery, superior nickel cadmium battery, is expected to replace traditional nickel cadmium battery. Ni-mh battery voltage of monomer, common model with 1.2 V nickel cadmium battery. His virtues are monomer battery capacity, low resistance, no memory effects, Defect is self-discharge higher. Battery capacity also widely used in the 5th (AA) battery, for example, single battery capacity of 1,000-1300MAH, widely used in mobile phone panels and digital cameras in power.
Rechargeable lithium ion batteries are currently polymer is advanced battery, it has the characteristics of high energy density, lithium batteries have light weight, small size, large capacity, no memory effect etc, but rechargeable lithium battery voltage is 3.6 V monomer, not directly substitution universal single day nickel cadmium/nimh batteries and demanding, need to recharge the battery chargers for. Due to the current lithium batteries depend mainly on imports, so the price is higher, mainly used in electronic products in high-grade
We usually need often buy rechargeable batteries are two main ahead. But it was generally lithium batteries battery products sell piece. Charge the battery life about 500 times, if use proper maintenance, can not only greatly extend battery life (many excellent battery can recycle 1000 times above), and make a battery capacity drops in minimum range and control for the users to save a lot of money.
