A battery charger is used to put energy into a rechargeable battery by delivering current through it. On the other hand, a battery amp meter indicates the battery charger's current delivery to the battery.
A battery charger amp meter shows the state of charge as the battery is being charged. Reading a battery charger will give the battery an extended life. It prevents overcharging of the battery, helps you calculate the current delivered to the battery, and indicates the amount of current delivered by the battery charger to your battery.
An amp meter is similar to a voltmeter only that a voltmeter measures the voltage between two points in a circuit. You should be careful when buying an amp meter, so you do not confuse it with a voltmeter.
Besides, there are different types of amp meters used in battery chargers. Three types of amp meters are used: the Direct Current (DC) amp meters, external shunt type meters, and the meter mounted shunt type. All these indicate the charging rate of the battery.
There are digital amp meters and analog amp meters. Digital amp meters do not have moving parts, as in the case of analog amp meters. The amp reading is displayed as an LED, thus easy to read. The analog amp meter has a needle-like object that moves inside a calibrated scale.
Before you start reading the amp meter, you must wear protective gear. Working with batteries is dangerous,
First, connect the charger to the battery. These are the steps to follow:
*Disconnect the battery from the car or any engine you are operating. Ensure the engine is not running.
*Ensure that the charger is off before connecting it to the battery. Also, the electrolyte level should be full.
*Now, connect the positive clip of the battery charger's cable to the battery's positive terminal. Do the same for the negative terminal.
Immediately you connect the charger, the battery starts charging after switching on the battery charger.
A battery charger is designed to a particular charging rate, including 2amp, 4 Amp, 10 Amp 16 Amp. When you switch on your battery charger, the amp meter needle deflects the desired charge rate like 10amp.
The needle moves down as the battery charges. Once the needle drops to half of the set amp, the battery is fully charged.
Amp meters can have one or two needles. The needle that is set to the desired amp is the one that shows the rate of current output to the battery by the charger. The other needle shows the amount of charge the battery contains. Besides, when the two needles coincide, you know your battery is full
Also, the amp meter is divided into two red areas. They are designed to show the charge rate that the battery charger is desired to deliver electric current.
A short circuit may occur in the battery being charged. The amp meter will show that the charger delivers maximum current and that the battery is mostly discharged. When the needle is observed not to move after 15mins, it is recommended that you discontinue charging.
The value of the amp displayed on the battery charger will depend on your initial amp rate setting. Once you connect and switch on your battery charger, it will show the value of the desired charge rate you selected.
A 2 amp value shows that the battery is charging slowly. Fast charging rate values like ten amps are read if the charging rate is desired to be fast.
Besides, a simple charger rated at two amps will take 24 hours to charge a flat 48 amp hour battery fully. Battery chargers come in different types depending on their charge rates. They range from 2 to 10 amps.
If you connect and see that the needle on the amp meter is not moving, the battery cells might be damaged, or the mechanical meter has malfunctioned. It should read the desired value when connected, and the drop as charging continues.
If the desired charging rate is 10 amp, the battery charger amp meter will show ten amps. This value will drop as charging continues. Once the battery charger indicates 1 or 2 amps, the battery is almost full. It is recommended you stop charging, or else the battery will overcharge.
An amp meter is connected to the battery charger to display the charging rate. The meter contains two needles that show ampere generations or state of charge.
For ampere generations, the battery charger will display a range of 2 amps to 30 amps. The readings on the state of charge can go from 25 to 100% higher.
If you set 10 amps as the desired charge rate, the battery charger will display that value first. If a three-phase battery charger is used, a constant value of 10 amps is shown.
As the battery charges, a point is reached where the battery charger displays a sharp drop in current. This means the charger is delivering a maximum electric current. When the battery nears a full charge, the battery charger will show a small amount of current. This means that the charger sends fewer amps to the battery as it gets to its maximum capacity.
It is vital to understand how to read battery charger amp meters accurately. You may have the best charger, but failure to read the amp meter correctly may damage. The damage occurs when the battery overcharges, and this does not guarantee an extended life.
The amp meter is vital in monitoring the amount of current being delivered to the battery while charging it. You are also advised to purchase these battery charger amp meters from recognized manufactures.
As earlier mentioned, amp meters are different from voltmeters. Be very vigilant as you purchase them. Reading amp meters correctly frequently will improve your battery's health.
The battery will also give optimum performance due to correct charging tips, and most importantly, it will have an extended life.
