Battery Chargers; What To Look For, Things to Avoid

Batteries, or dry cells are manufactured to supply steady and uninterrupted D.C capacity to different present day gadgets running with electrical power. Batteries are generally lead-acid cells. Over 15 billion are made every year and therefore are sold worldwide. Many of these are alkaline-batteries which are discarded after being used for any single time. But there are also some which may be charged again and again after every use and are referred to as "rechargeable batteries". These ought to be kept at fully charged condition in order to satisfy the D.C. power demand whenever needed. Therefore suitable battery chargers have to charge those types.

The various kinds of battery chargers are:

1) Medical

2) Automotive

3) Commercial

4) Industrial

These may be stationary or portable.

These rechargeable batteries are of high capacities. Rechargeable batteries, like Nickel-Metal Hydride (NiMH) or Lithium-ion (Li-ion) batteries could be charged several hundreds of times and last far longer time in high drain devices.

Battery Charger

By using these repeatable charging batteries people can save tons of money. When the charge falls below a certain level it stops supplying D.C power to electrical instruments, then your battery needs to be charged to regain its capacity of supplying D.C power. Low quality chargers can even damage batteries and shorten their lifetime. The charger takes current directly from electric lines and induces the electric charge into the batteries.

The charging of these depends on different factors for example its capacity, wear and tear, its initial charges, etc. Different chargers vary widely in this matter. There's a tendency of generating heat during the charging of rechargeable batteries which is probably the most commonly cited factors for the harm to these battery. The heat mainly generates because of the internal resistance and chemical reaction of the rechargeable batteries. Excessive current may also damage battery after it is fully charged.

There are several automatic chargers which initially charge in a very high rate and continuously monitor the cell voltage to lessen or shut off the charging when the battery has a tendency to charge fully. Battery chargers may take 1 hour to 8 hour of your time for charging depending upon the design and ratings of those chargers. There are also different visual indications like LED around the rechargers. These indicators indicate the rechargeable type batteries should not get overcharged and help them preventing them from overheating.

These day there are wide applications of rechargeable styled batteries. These kinds are even utilized in power generating stations as an alternative of D.C current and emergency Lighting System. They are also used in vehicles like cars, trolleys, bus, etc. There are also some battery driven cars which run on streets completely based on battery-power and not on fuel.

Using rechargeable batteries can also be found in laptops, IPods, cell phones, motorized wheel chairs, etc. Therefore suitable chargers are essential for the charging of those re-chargeable batteries.
