We are going to talk about how long to charge a car battery at 2 amps and some other topics today!
Recharging battery usually takes some time. Fast charging of storage cell can reduce its lifespan for some reason of it produces more heat.
Moreover, quick charging may cause overcharging. That’s why slow charging is more recommended than fast charging. However, slow charging will consume a lot of time.
A basic charger charges typically at 2 amps which require 24 hours to charge a 48 amps storage cell fully.
In the market, you can find and choose from two to ten amps charger. Ten amps charger can be used when the storage cell is entirely dead or drained.
It is commonly used in automobile vehicles with larger storage cell while 2 amps charger can be used to condition a storage cell.
Also, 2-amp rate charger is commonly used for motorcycles which contain smaller storage cells.
What is amperage? Amperage or amp is the strength of an electric current in amperes. It was named after the French mathematician and physicist, Andre-Marie Ampere.
Is it important to care about charger’s amperage? Well, some never really care about charger amperage because they are clueless about it.
Some think that chargers are made equally, but the real thing is, chargers vary from one another. That is why it is essential to get the right charger for your storage cell.
Using the right charger for your cell pack is important as it measures or gets the right current for it.
Some think that charging your devices or storage cell with different chargers or amp will blow it but it won’t. Amperage or amp rate is important it tells how fast a charger is for recharging a specific cell pack or devices.
Checking Ampere Using a Multimeter
How do we test battery amps with a multimeter? Why does measuring amperage is important?
In electrical systems, measuring amperage is important to ensure that the wires aren’t handling more current than they supposed to have.
Amperage can be measured using a multimeter. Multimeter or multitester is an electronic measurement device which can be used to measure current, voltage, and resistance.
There are two types of multimeter, the analog and digital. The analog uses a moving pointer while a digital multimeter shows numbers to indicate the measured value.
Many people prefer digital over analog because they are more precise and more comfortable to use than analog multimeters.
Below are steps on how to measure or how to check the amps with a multimeter:
1. First, set the multimeter to ohms let the test probes have contact with each other to test whether your multitester functions appropriately. When removed, the readings should be 1, if not then check your multitester’s battery.
2. Find out the amperage rating of your multimeter to avoid destroying its fuse.
3. Set your multimeter to AC or DC to measure the correct amperage. Household power is AC while batteries are DC.
4. Set the range on your multitester.
5. Plug the right probe into their correct terminals.
6. Put the red probe of your multitester to the battery’s positive terminal (+) then put the black probe on the battery’s negative terminal ( – ).
7. Finally, look and note down the measurement of the multitester.
AC and DC
There are two different types of electricity, the Alternating Current, also known as, AC and the Directing Current or DC.
Car batteries are secondary batteries which means they are rechargeable batteries. Therefore, an auto battery is DC.
We nowadays take for granted batteries and overlook their importance. But, storage cells are essential in our daily lives.
We can see it on our electronic appliances, mobiles, toys, and almost every electronic device. Without it communication, work, as well as traveling is hard.
Batteries made our life easier and faster. In this article, we talked about checking battery using a multimeter, AC, and DC, and how long to charge a car battery at 2 amps.
