A disposable multi-purpose battery is generally referred to as alkaline battery. In some cases, alkaline batteries are rechargeable depending on its components. Alkaline batteries are available in many ranges from 1.5 volts to 9 volts. Even higher range batteries are available for special uses. General applications like clock, remote control need more than one cell as basic requirement. When combined together, the batteries produce higher voltage enough to power various operations.
Generally speaking, almost all alkaline battery units contain electrolyte solution such as potassium hydroxide (KOH). Zinc-carbon batteries feature acidic electrolytes which are less efficient and produce hazardous by-products after disposing off. Considering capacity, alkaline battery is much better than regular zinc-chloride cell as it provides higher voltage and less power dissipation.
Regularly used alkaline batteries are of AA or AAA size. Capacity of alkaline batteries relies heavily on the load. Heavy load batteries provide less capacity with continuous discharge.
Leakage is one of the biggest problems with alkaline battery use. Potassium hydroxide stored in the battery is leaked as a caustic agent after long time. The agent can cause serious respiratory damage or skin irritation. You should not attempt to recharge disposable cells and forcefully mix different types of cells. Extreme care is required in case of alkaline batteries as if not stored in a dry place, the battery gets prone to leakage. It is advisable to keep batteries separate from the machinery when not in use for a long time. Special disposal methods are implemented in case of alkaline batteries.
