Different batteries have different chemicals inside them which varies the power output and life cycle of the battery.
Most batteries contain chemicals that would not harm your exposed skin, however, a leaking battery should be handled with care and precaution. The chemicals in a battery should not be placed near the eyes or ingested. You should consult a doctor immediately if this happens.
Always follow the instructions on your device as to how you must align your batteries. Never put the batteries the wrong way around as that could damage your device and battery.
You should remove the batteries inside a device in the following circumstances:
No, only batteries which are labelled as 'rechargeable' can be recharged. Do not try to recharge other batteries as they could get damaged in the process.
You can increase the life of your batteries in the following ways:
Never mix old and new batteries in a device. This can lead to a decreased performance by the device and damage the batteries.
Never mix different types of batteries as they have been designed for different uses. For example, mixing a zinc chloride battery with an alkaline battery will lead to a poor performance of your device and can damage the batteries.
Also, do not mix batteries from different brands in a device as that can also lead to damaged batteries and a decreased performance by your device.
Primary Battery:A primary battery is a battery that is designed to be cycled (fully discharged) only once and then discarded. Although primary batteries are often made from the same base materials as secondary (rechargeable) batteries, the design and manufacturing processes are not the same. Primary batteries should not be recharged. Although attempts at recharging a primary battery will occasionally succeed (usually with a diminished capacity), it is more likely that the battery will simply fail to hold any charge, will leak electrolyte onto the battery charger, or will overheat and cause a fire. It is unwise and dangerous to recharge a primary battery.
Types of Primary Batteries:Zinc Carbon: A zinc carbon dry cell or battery is packaged in a zinc can that serves as both a container and anode. The cathode is a mixture of manganese dioxide and carbon powder. The electrolyte is a paste of zinc chloride and ammonium chloride dissolved in water. Zinc carbon batteries are the least expensive primary batteries and thus a popular choice for low-drain devices. They can be used in remote controls, flashlights, toys, or transistor radios, where the power drain is not too heavy. To know more about uses of zinc carbon batteries, click here.
Alkaline Batteries: Alkaline batteries are a type of primary battery. Compared with zinc carbon batteries, while all produce approximately 1.5 volts per cell, alkaline batteries have a higher energy density and longer shelf-life. The alkaline battery gets its name because it has an alkaline electrolyte of potassium hydroxide, as opposed to the acidic electrolyte of the zinc carbon batteries which are offered in the same nominal voltages and physical size.

Rechargeable Battery:It is usually designed to have a lifetime of between 100 and 1000 recharge cycles, depending on the composite materials. Secondary batteries are, generally, more cost effective over time than primary batteries, since the battery can be recharged and reused. A single discharge cycle of a primary battery, however, will provide more current for a longer period of time than a single discharge cycle of an equivalent secondary battery.
