How Do Y'all Read a Battery Charger Amp Meter
How to connect a battery charger
Before we can employ the amp meter on the battery charger, nosotros first need to connect the charger to your bombardment. That seems simple plenty, but there are some precautions you demand to accept. The steps beneath are the safest method for connecting your battery charger:
Step 1: Brand certain the battery terminals are clean. While the bombardment is fitted to your car, it will go covered in road grime. And so check these are make clean first.
Stride ii: Make sure you are in a well-ventilated surface area. Batteries give off hydrogen gas, which is explosive.
Pace three: The battery contains acid. We recommend you wear center protection and gloves while working on your battery.
Step 4: If the battery is fitted to the car, brand sure yous turn everything off. Things such as the radio and interior lights.
Step 5: Identify the positive and negative bombardment terminals. Positive is red and negative is blackness.
Pace 6: Connect the ruby-red cable from the charger to the positive red battery terminal.
Step 7: When you connect with the black final, information technology may cause a spark. This could ignite any hydrogen gas in the air that has come from the bombardment. For this reason, it is safer to connect the black terminal a distance abroad from the battery:
- If the battery is fitted to the car, connect the black cable from the charger to the engine block or part of the chassis. Look for a site well abroad from the battery.
- If the bombardment is removed from the car, connect a two-foot slice of battery cable to the negative concluding. So connect the charger black cable to this, again well away from the bombardment.
Step 8: Now you can switch on the charger and check the amp meter.
How practice y'all read a Battery Charger Amp Meter?
The amp meter on your battery charger has several sets of numbers. Let'south get through the gauge shown in the video below, one at a fourth dimension.
Charge Rate
At the lesser of the meter is the charge rate. The numbers shown will depend on your battery charger. In the prototype above they correspond the number of amps flowing into the battery betwixt zero and twelve.
Percent Charged
Above the amp scale is the percent charged scale, showing how well charged your bombardment is. As the battery becomes charged, the needle moves from correct to left. This shows a reduction in the number of amps flowing, and an increase in percent charged.
The accuse% row the needle is at about lx% telling you the battery is almost 60% charged and eventually the needle should get to the left when looking at it most 100% charged or cartoon almost nil amps.

Red and Green Triangles
The image higher up relates to a charger with two charging rates, 2 amp and 12 amp.
12 Amp Charging Current:
The large cherry triangle shows the corporeality of current (amps) flowing from the charger to the bombardment. Equally it charges the battery, the flow rate decreases. The needle moves to the left, and into the green area. When the battery is fully charged information technology will indicate around vi amps.
2 Amp Charging Current:
The small red triangle shows the amps flowing on the 2 amp setting. Again, the needle moves to the left as the bombardment becomes charged.
How do you know when a battery is charged on a bombardment charger?
When you first connect and switch on the charger, the needle will move sharply to the correct.
After a few seconds, you will run into the needle gradually move to the left. It volition settle at a steady charging betoken, showing the amps flowing. This is a good sign that the charger is working.
How to tell when a bombardment is fully charged on a bombardment charger?
On the 12 amp charging setting: The needle will settle at around 6 amps, or just under. This is showing that the bombardment is fully charged.
On the 2 amp setting: The needle will settle near the end of the pocket-size red triangle when fully charged.
The needle volition settle at around half the input setting you selected when the bombardment is full. On a 12 amp setting, the needle will testify around 6 amps when the battery is charged.
The below video volition evidence you lot how to read a bombardment charger gauge in 1 minute!
Problems When Reading a Battery Charger Gauge
Bombardment charger needle jumping
- Poor connection: If the charger clips are not making a adept connection to the terminals, this may occur.
- Defective battery: A battery that has go fully discharged or has some internal defects may cause this.

1. Charger amp meter mistake
To eliminate a fault with your charger, connect it to a known good battery. If it shows the aforementioned problem, information technology's most likely a fault with your charger.
two. Battery charge is too low
Standard battery chargers volition not piece of work on a completely flat battery. Even modernistic trickle chargers with maintenance style tin struggle.
But there is a way around this. You can place another battery that has a good charge, in parallel with the bad battery.
Connect the two batteries together using jumper cables, positive to positive and negative to negative. Exactly the same equally bound-starting a auto. Now connect the charger. The bad battery should now exist able to have a charge.
3. Dirty battery terminals
A car battery can get covered in a lot of dirt, and battery terminals tin corrode. If the battery is non charging, then check the terminals beginning. Make clean them and try again.
4. The amp meter needle is stuck
Mechanical needles can be prone to sticking, especially if the charger is old. Gently tap the meter and run into if it moves.
five. Your Air-conditioning outlet is faulty
The power supply from the AC outlet must exist good for the charger to piece of work. Y'all tin bank check this past plugging in another electrical item such every bit a lamp.
Decision
Many people don't have a inkling how to read the meter on their battery charger. Hopefully, this short guide has given you a sign of how useful the meter is.
Knowing how to read a bombardment charger amp meter is useful in many ways. Not but can information technology show the status of your battery, but it tin can also help to diagnose charging problems.
So next time you are charging your battery, have a little time to await at the charger's amp meter.
