Disposable batteries commonly known as "disposable" batteries, because they are exhausted, can no longer charge use, can only be discarded. Common disposable batteries include alkaline manganese batteries, zinc-manganese batteries, lithium batteries, silver-zinc batteries, zinc-air batteries, zinc-mercury batteries and magnesium-manganese batteries.
Rechargeable battery According to the production of materials and process of different, common lead-acid batteries, Ni-CD batteries, nickel-iron batteries, Ni-MH batteries, lithium-ion batteries. The utility model has the advantages of long cycle life, which can charge and discharge more than 200 times, and some rechargeable batteries have higher load power than most disposable batteries. Ordinary Ni-CD, Ni-MH batteries in the use of special memory effects, resulting in the use of inconvenience, often cause premature failure.
Ordinary batteries are disposable, while rechargeable batteries can be recharged with chargers and reused.
Ordinary 1, 2, 3, 5, 7th Unit battery nominal voltage is 1.5V, and Ni-MH, ni-cd rechargeable battery nominal voltage is 1.2V, lithium-ion rechargeable battery nominal voltage is 3.7V, lead-acid battery is 12V.
