A battery is composed of electrochemical cells converting chemical energy into electrical energy, with both positive and negative electrodes. A positive electrode holds discharged ions, while negative one holds discharged ions. A battery can come in different shapes and sizes that are classified into primary or secondary battery.
Primary power supply convert chemical energy into electrical energy. Secondary batteries, on the other hand, have the capability to recharge and restore back to original composition, after being used. Secondary batteries must be charged prior to usage.
The rechargeable batteries are activated by electric current. The current reverses the chemical reaction. Lead acid battery is one of the famous forms of rechargeable source of power. In the automotive industry, the most popular one is the valve regulated lead acid battery. It is usually used to replace the lead acid wet cell.
Battery tender is usually used in charging batteries, as well as maintaining the level of charge. It is useful for vehicles and appliances, which are not used for some time. It’s a battery maintainer that charges the batteries for a long time.
Nevertheless, users don’t have to worry about overcharging or bursting due to excessive charging. Technically, it can also be defined as a device that is typically plugged in a standard AC outlet.
When it is plugged in the outlet, the power is transferred into a 12 V battery, keeping it operational for longer period of inactivity. A Power Tender Plus is designed to charge a battery, until it’s full. It doesn’t cause damaging effects or overcharge the power supply.
Some famous brands of battery tenders have 4-step charging program, to prevent overcharging. The four step program includes the following: bulk charge, initialization, absorption mode and float mode. A Power Tender Junior is a compact and lightweight device, yet capable of charging the power fully.
Some types of power supplies include the following: wet cell, dry cell, molten salt and reserve. Wet cells contains liquid electrolyte. These cells are precursor of dry cells. A dry cell utilizes paste electrolyte. It can operate in any orientation without any spill.
Zinc carbon power support is an example of a common dry cell battery. Zinc anode is usually composed of zinc anode, in the form of cylindrical pot. It also has a carbon cathode, in the form of central rod. Molten salt batteries utilize molten salt as electrolyte. A reserve power supply is assembled first before it can be used.
Batteries are indeed powerful and very useful.
