Battery and Rechargeable Battery? Battery Types?
What is the Battery?
The battery is the most compact electric power source. The batteries produce electrical energy as a result of the chemical activities taking place inside. The battery is packed together with chemical compounds ready to react in manufacturing. When the current is drawn, chemical reactions occur. The chemistry can pull the current through the coil until it completes the reactions, and eventually, nothing remains from the original compounds.

As technology develops, most of the electrical appliances we use in our homes become wirelessly usable. The key requirement for all of these portable electronic products to be able to handle their developed functions over a long period of time and efficiently is to have a high energy density, safe, easy to maintain, short-time rechargeable, and non-destructive energy source.
Along with the widespread use of electronic devices, battery usage rates are also increasing. In this process, different designs have appeared to be used for different types of pills and different purposes. There are several types of batteries in different structures, depending on the type of chemical reaction;
It is the cheapest battery type. It generates 1.5 V. The voltage decreases slowly as the battery is used. It may leak in the old and metal parts may be exposed to corrosion and damage the devices.
Standard duty heavy-duty cylinder. It generates 1.5 V. Zinc-carbon holds a lot more weight than pillars and is cheaper.
The button-shaped button is the battery. It produces 1.4 V. It gives a small current for a long time.
The same amount of zinc-carbon carries 3 times more load than the coil, but it is more expensive. It generates 1.5 V. Zinc-carbon can give more current to the coil. Voltage remains constant over the life of the product; in the end it suddenly falls. It does not leak. This feature should be kept in mind because it suddenly shows a fall.
In standard sizes, it is a silver-oxide-like button pillar. It generates 1.5 V. It produces a small current for a long time (1-2 years), but it can produce a high current for a short time.
What is a Rechargeable Battery?
The rechargeable battery is now widely used in portable electronic and electrical goods thanks to its superior features. Rechargeable batteries are used for the uninterrupted power supply or occasional large currents. When the energy is exhausted, the rechargeable battery is connected to a charger from the mains supply. This will make the chemicals on the pans back into their original form.

It produces 2 V. It can give high current. Portable, lead electrodes heavily strain the battery. There is a danger of acid electrolyte leakage. It is used in starter motors of automobiles.
Zinc-carbon in the same size holds less load on the coil. It generates 1.2 V. When nearly all discharge occurs, the voltage drops suddenly. It can give a high current. There is a memory effect. It may remember the level to which it is discharged. After recharging, it stops delivering current if it falls to the recalled level. This reduces current capacity.
Nickel Metal Hydride (NiMH)
The nickel-cadmium battery of the same size holds twice the load of the charge. These batteries are more expensive. 1.2 V and does not show the memory effect of nickel-cadmium. It is used in electric vehicles.
