• They supports various shapes and sizes altogether
• They are designed and delivered to aim long life period
• They are used in low current devices
• They are used in portable devices.
The compositions that are used in the AA batteries are nickel cadmium and nickel manganese. The composition in the battery is made up in such a way that they are capable of self-discharge. Also it is necessary to mention that the batteries have less effect of force, pressure, moisture and other environmental conditions compared to other cells. The alkaline technology was established and evolved long years back in Canada and it was licensed to deliver pure energy.
But with the advances in technology, sub sequential patents of the batteries came up. The batteries are capable to hold the charge that is stored inside and the energy for long period of years is it not used. The batteries composed using alkaline technology are cheaper than batteries with other technology. The batteries are discharged by less than 20% usually and they can be recharged many times by following the energy cycles. The available energy increases per each cycle while charging. And while using the battery, available energy decreases in cycles.
This happens because they have relative high resistance. There are number of cycles to be followed. But the cycles are followed till the level of voltage capacity is reached. The construction of the battery same as that of dry-cell. For more information visit here.
