Why does a disposable battery have no capacitance?
In the small current, intermittent discharge conditions, the quality of a battery than the ordinary secondary battery capacity, but when the discharge current is greater than 800mAh, then the battery capacity advantage will be significantly reduced.
A battery internal resistance large secondary battery, the high current discharge performance is not the secondary battery.
Secondary battery relative to a battery more environmentally friendly. A battery must be abandoned after use, and rechargeable batteries can be used repeatedly, in line with national standards of the next generation of rechargeable batteries can often be used repeatedly more than 1000 times, that is, rechargeable batteries generated less than one minute of the battery 1 / Whether from the reduction of waste or from the use of resources and economic point of view, the superiority of secondary batteries are very obvious.
A self-discharge of the battery is much smaller than the secondary battery. Once the battery can only discharge once, for example, alkaline batteries and carbon batteries belong to this category, the secondary battery can be used repeatedly.
Once the battery is the primary battery (primary battery), is the battery can not be recharged after discharge to restore the battery, usually the battery has a positive, negative, electrolyte and containers and diaphragm composition. Such as zinc-manganese batteries, alkaline zinc-manganese batteries.
