home Home Backyard, Others ABOUT CHARGING THE BATTERY


The (lead-acid) batteries as we know it has been invented in the 19th century. It is a proved reliable power source. Maybe a bit clumsy, but mounted in a vehicle often counts less, and it is often the only primary source of electrical energy we need to take with us. Along the way, the charging circuit charges of our vehicle automatically to best car batteries.

But what if we want to charge a battery charging circuit without a car, motorcycle or boat? Whether we like the car battery during the winter in top condition. Keep? Maybe you have an older battery that can boost use.

In such cases, a battery charger that operates an outcome through mains. In this article, we elaborate on the operation of the charger and give you practical tips to make your battery in top condition and keep. You will see that behind battery charging again lies a whole world!

Batteries – Introduction

A battery is an indispensable energy source when, where no outlet is available, to use electrical equipment. In combination with a good inverter to 220v, you even exist anywhere an electrical outlet. The most common batteries give off a DC voltage of approximately 12 volts. In front of some applications, such as trucks or boats, there are 24-volt batteries. This article is based on a 12-volt battery. However, the principles outlined also apply to 24-volt batteries.

A battery is an energy reservoir. You can draw energy and boarding. Compare this with a bucket you fill with water. As long as you may not use the remains full (apart from a small leak or dripping faucet) and if you water bleeds he deflates. The effluent can give energy to which would be able to generate electricity.

A battery consists primarily of a combination of lead and acid and is therefore popularly called a lead (acid) battery. The lead plates hang in a container filled with sulfuric acid. A battery pack is made up of cells. One has single cell,

If charged, a voltage between the + and – connection of more than two volts. A 12-volt battery, therefore, consists of six of such cells which are connected to each other. A 24-volt battery is composed of 12 cells of 2 volts, of course, housed in a single enclosure.

The ideal battery meets the following criteria

-You Can not fill him

-All Energy that goes in there again can from

-The Energy can very quickly be taken out (for high power)

-You Can charge and discharge him endlessly

-Has no self-discharge

-Does not require any maintenance

It probably will not surprise you that this ideal can not be achieved. In an always strive to get right in the neighborhood, there are many different battery types, spoke, even more, brands. For serious mobile use, the battery falls off. A battery of a car designed to be able to supply a lot of current for a short period. This type of battery should not be too much discharged. There is therefore relatively little energy to be achieved. The difference with a vehicle battery is mainly the surface of the plates with lead in the battery. With increasing the size of the battery plates, the acid can easily penetrate the plates which increased current flow makes possible. The main feature of a battery is that this has vast and small plates. The battery is not suitable for cyclic loads (I.e., continually charging and discharging) in a 12/24 volt system to the feed lighting. A battery is relatively cheap.

There is the (semi) for mobile use traction battery. The semi traction battery, the most used for recreational purposes and is commonly referred to as a domestic battery. It is on a starter battery more expensive to buy, but much nicer to use. The battery can be discharged much deeper. In a gel battery the liquid lead acid trapped in a gel. This offers advantages such as a more deep discharge, low self-discharge and flexible mounting options. Over there is a high price tag in front as well as lower capacity about its weight than the liquid battery.

Which battery you have, make sure the battery pack never stays long time discharge. Battery, which type you have, do not find it useful to be removed. A discharged or “empty” battery pack is subject to formation of sulfate. This insoluble salt collects in the bottom of the battery and between the lead plates. Too much time dangerous charging condition worsens the sulfate formation and threatens the life of the battery. It accompanied with loss of capacity.

Have a battery used for a long time, charge it again completely on as soon as it possibly can. Also, a battery that long time is not used regularly should be recharged as it is subject to self-discharge. A typical, “wet”, the battery can be up to 10% of its charge per month spontaneously lose a good gel battery around 2%. The energy that can provide a battery is also dependent on the ambient temperature. This explains the well-known phenomenon of refusing starter batteries, which should not less than 80% of their capacity at least are discharged, in the winter.
