This piece can help you if you need to know what all those pins and needles on that ampere meter mean for your charging sessions. But this piece also covers on other matters like some terminology and other considerations—getting to know how to read a battery charger amp meter is more than you think.
If the battery is as flat as the Netherlands then quite a while. If the charger has a boost or turbo setting then try that to get the battery kick started. Feb 07, 2008 I wish you're able to have listed greater tips with reference to the battery you opt to cost. Often speaking you're able to be able to recharge a chargeable battery yet a 2 amp charger is in the ragged ege of too lots charging amperage. You would be safer with a small.Battery comfortable (call style ) charger. An automotive or car battery charger rarely goes wrong. A battery charger doesn't contain any moving parts and is simply a device that transforms mains alternating current (AC) into direct current (DC) at a much reduced voltage (usually 12 volts). The internal wire windings that transform the electrical current from AC to DC are not DIY. Alternator is not designed to charge up a battery but only top it off while headlights etc are on. After a jump start (which you should never need or do) you MUST put that battery on a charger for 12 - 24 hours. A battery that has gone dead twice for any reason is no good. Replace it with the right one, not one you think will work. Before charging, the battery tested at less than 1 volt. After charging 14 hours, it shows 3.5 v. Checking output of the charger, I get 4.5 volts. The test/charging indicator needle does not move. Is it operating properly or not, and why? I do some household electrical repairs, but I'm not familiar with DC or electronics at all.
What Should A Battery Charger Read—And What It All Means For Your Car?
All right, so the process of adequately charging your car battery will involve some critical terms that need to be in mention:
• Amps
• Amp Meter Of Your Charger
• Amp Meter Of Your Charger
Now, and this is especially true with the 2nd term, you will need to know the general rule of thumb when it comes to using your amp meter.
AND, THE RULE OF THUMB IS THAT ON THE AMPERE METER
• One of the needles tells you the number of amperes (which can range from 10-amps to 30-amps, depending on your setting) your charger is generating
AND, SOME AMPERE METERS WILL CONTAIN

• An “extra” needle that tells you the amount of “charge” your battery currently contains (depending on your setting, it can range from 0, 25, 50, 75 and, of course, 100).
JUST REMEMBER THOUGH
• More often, you must plug in the battery charger to get the initial needle to move around then set your charge to a target range of amps
• If the amps set to a 10, your needle moves around that point range, and it is in “full charge” when the needles move around below half the amount of your target point range (which is the 10).
• For the “extra” needles, a sign is that whenever the needles are on the top of one another (overlapping), you will get the idea that the charger is at “full charge”—with the necessary amperes in place.
Also, down below are some quick notes you can take regarding the terms above.
Amps.
• Amps or the formal term, ampere, is a designation term that refers to how much useable chemical energy is in allowance to turn into electrical power.
• The chemical energy, of course, is the sulfate acid material available in your battery.
• The electrical energy, then, is the equivalent units that come from the movement of your battery cells.
• Amps are the “bridge” or the “gateway” or rate of flow for your chemicals to become an energy source for your vehicle—in this case, your car.
• Voltage is more of a designation term that refers to the possible amount or pressure of energy in your battery—this is one of the reasons why amps are the terms available when charging.
• If the amps set to a 10, your needle moves around that point range, and it is in “full charge” when the needles move around below half the amount of your target point range (which is the 10).

Amp Meter Of Your Charger
• Now, since amps are the ones that you will measure when a charging process happens, it is essential to use a device that offers a specific measurement of these units of energy.
• Amp Meters are widely available across different manufacturing sites and shops because of their accuracy in measuring out amperes whenever a charge session occurs.
• These meters will usually possess needles that indicate ampere generations or states of charge—most of the time, both are in utility.
• For the ampere generations, the ranges can go from as low as 2-amps to 30-amps or even higher
• For the states of charge, the levels can go from as little as 25 percent to 75 percent and 100 percent.

It is important to remember that you need to connect your charger correctly before you can even use the ampere meter.
Here are some quick tips on how to do the above process:
1. Open the hood of your car to find your car battery.
2. Get the car battery out of your car by removing both the negative-positive connector leads from their diode.
3. To loosen the clamp lead’s end, you can use a screwdriver tool to unloose—just enough to relax, though, nothing more.
4. Take your leads from their clamps, all while making sure you go through the positive (+) point first, and then, the negative (-) lead next.
5. Keep to making sure that your car’s system is off—and no “on” ignition keys!
6. To connect the charger wires of your battery with the cables of your clamp leads—hook them up to a post if you need to do so.
7. Remember to keep the same process of connecting the wires with the clamps: positive (+) goes with positive (red), and negative (-) goes with negative (black).

All in all, the information up above can get you at the ready whenever you need to review on properly charging your battery—the last thing is to try it all out at your own pace.
How Many Amps Should A Battery Charger Show When At A “Full” Charge?
The facts are that it is up to the consumers on setting up their preference when it comes to ampere range—since amperes ultimately refer to the pace or flow of energy passing through the system.
HOWEVER, YOU CAN
• “Trickle” Charge – which is much lower amps in the generation, but safer.
OR, YOU CAN
• “Quick” Charge – which is much higher amps in a generation, but not as safe (depending on a lot of factors).
Undoubtedly, it seems, a “full” charge is indicative of two markers.
THE FIRST IS
• A percentage level of 100 on the ampere meter.
THE SECOND IS

• A voltage range of 13.0 on your meter of measurement (if available on your ampere meter, all the better).
How Long Does It Take To Charge A Car Battery With A 6 Amp Charger?
Charging duration involves a lot of things, usually in “unison”:
![Battery Charger Needle Not Moving Battery Charger Needle Not Moving](https://bassanglermag.com/wp-content/uploads/bi-directional-battery-charger.jpg)
• The current-voltage of your battery
• The ampere performance of your charger
• The cranking or cold-cranking amperage of your battery
• The ampere performance of your charger
• The cranking or cold-cranking amperage of your battery
If you possess a product possesses around 500 in CCA and is currently below the standard 12-volts and if your charging dishes out about 5 or 6 in ampere rate of charge, you are looking at 12 or even 13 hours duration of charging.
This scenario tells you that just knowing how to read a battery charger amp meter may not be enough, you need quality battery products, too.

Battery Charger Needle Jumps
There are situations where a 'smart' battery charger won't recognize a battery because the battery is deeply discharged. Some chargers have a relatively high voltage threshhold. Remember, a 12 volt battery (adjust numbers for 6 volt, etc.) is effectively discharged at 11.9 to 12 volts (fully charged is 12.72 volts). A battery can be drawn lower than this, particularly if allowed to remain totally discharged for extended periods. This is not particularly good for battery health, and may in fact destroy the battery, but that is not for this discussion.
Some of the more common 'floating chargers' for vehicle or other battery maintenance, have threshhold voltages between 8 and 11 volts. If your battery voltage is below the particular level of your charger, the charger won't acknowledge a viable battery hookup, and won't pass current. Some chargers indicate a fault mode (continuous flashing), and others just don't do anything. Some charger manufacturers don't consider a battery below their threshhold voltage as worth recharging (they're not necessarily correct). Some, particularly marine battery chargers, are designed to check for battery voltage before passing voltage/current to prevent sparks, in case the charger is plugged in without being connected to a battery, when there may be a gas buildup in the compartment. All of our chargers have very low threshholds, and will charge deeply discharged batteries.
How to deal with this
There are a couple of ways to get around this, to see if your battery will recover and take some charge. It still may have to be desulfated later. First, a non-intelligent charger, like you had in your garage 25 years ago, may be used with supervision, to cram some current into the battery, which will raise battery voltage. This is another case for having a decent digital voltmeter around the shop/house. You can keep checking the battery until it has enough voltage to register on the 'smart' charger, then let the smart charger take over. If you have golf cart type 6 volt batteries, you can series a pair (positive to negative) to look like a 12 volt battery, and use a 12 volt charger as above. Second method, if you don't have a 'dumb' charger: parallel a second battery (positive to positive, negative to negative) that you know to be recognized by the charger, with the bad battery, and attach the charger. After the charger has a while to put some current back, disconnect the good battery. It may take a time or two to get the charger to stay running. What you don't want to do is leave both batteries connected for a long time, as the good battery will end up overcharged. So, both methods require supervision.
