Introduction To Battery Chargers
If you use items that run on batteries, where the battery drain tends to be intense
and you have to replace them often, switching to rechargeable batteries can save you money in the long run. Battery chargers come in all sizes allowing you to charge two, four and up to 20 batteries at a time. You can plug a charger into any standard wall socket or use an adapter to plug into your car's 12v socket. Some even have small solar panels to allow you to charge your batteries while outdoors. No matter what type you have, the battery charger instructions for each are the same.
Charging battery also depends upon the flow of electric current and the suitability with the equipment to be charged. Like, a mobile phone will not need 12 volt battery charger- it is used in cars. Batteries are of different shapes and sizes. You can compare the battery size installed in mobiles with those used in cars or generators. Sustainable charging are those that require long time to charge.
Look at the charge indicator light. It is typically located on the upper right or lower right corner of the charger battery compartment. It should be a solid red light. If the light is not on then check your power source (clean the top of the case if it is solar as there may be too much dust on it for the solar panel to work). If the light is red but flashing then remove each battery and wipe it with a paper towel to remove any debris that might be interfering with the connection and reinstall the batteries. If the light is still flashing red, remove one battery at a time until the light stops flashing and turns completely red. The battery you removed just before the light went solid red is bad and should be discarded.
Also, never keep chargers in reach of children. Keep them dry, safely tucked away as they emit harmful gases detrimental to general health. Every battery has the provision to show the amount of voltage input. Depending on equipment, it can vary from 12 volt to 24 volt power. Some machines needs to be charged overnight. Remember to connect charger and battery at opposite ends- the negative (-) side with the positive (+) side, and vice versa.
Always carry wherever possible battery chargers. If you are driving a car, you can store the 24 volt battery charger at the back or if you are using mobiles, carry the charging plug in pocket. With time, batteries lose its capacity. Then, either they have to be replaced or buy a new one.
There are types of chargers- simple (works on DC power), trickle (slow charger), timer based, intelligent (works out battery output and time automatically), fast, pulse (feeding DC pulse), inductive (uses electromagnetic induction), USB based, and solar chargers.
Using heavy chargers like 24 volt battery charger increases the monthly electricity bill too. So, use wisely and buy good charging products seeing not the money but the quality. Service them occasionally to prolong its life.
Types of battery chargers
A simple charger works by providing a constant DC power to the battery. A simple charger will not alter its output based on time or the charge on the battery. These type of battery chargers are usually cheap, but there is a trade-off in quality. Typically, a simple charger takes far longer to charge a battery, and a battery left in a simple charger for too long will be severely damaged by over-charging.
Timer based chargers operate much like a simple charger, but (as the name would suggest) they operate on a timer. The timing would be set for a particular battery and then left. However, if batteries of lower capacity were charged they would be then overcharged and if batteries of higher capacity were charged they would be only partly charged. Timer based chargers also have the drawback that charging batteries that were not fully discharged, even if those batteries were of the correct capacity for the particular timed charger, would result in over-charging. Battery charger output current depends upon the battery's state. An intelligent charger may monitor the battery's voltage, temperature and/or time under charge to determine the optimum charge current at that instant. Charging is terminated when a combination of the voltage, temperature and/or time indicates that the battery is fully charged. In a sense, the batteries tell the charger when they are full.
