Charging At 50 Amps Is Fast But It Has Its Consequences Stay Safe
A 50-amp charger is fantastic. But exercise caution. The battery runs the risk of overheating at that rate. Higher amps can result in faster charging times. Issues are more likely to occur if the charger is left on after the battery is fully charged. Whichever charger you choose, you should always remove it as soon as the battery is fully charged again. By using a slower charger, you can eliminate this risk. A 10 or 12-amp charger completes the task securely and expediently.
Battery State Of Charge
The charging time above is only recommended for a flat or empty battery. It should be reduced if the battery has some remaining power.
You can determine the state of charge by getting the batterys actual voltage. When the voltage is 12.7V, it means the battery is full. Meanwhile, 12.4V is 75% 12.2V is 50% 12V is 25% and anything under 11.9V is considered empty.
How Long Does It Take To Charge A Dead Car Battery
Generally, it will take 2 to 4 hours to fully charge a car battery with a 20 Amp battery charger and 12 to 24 hours with a 4 Amp charger. The charging time heavily depends on the car battery and the chargers power output.
The most common rate for car battery chargers is around 4 amps. To fully charge a battery of the size 52 Ah would take about 10 hours from dead to fully loaded, but you could probably start your car within 1 hour.
First, you have to look at your car battery charger to find out how much ampere its giving out. High amperes charge your car battery faster. Low ampere is better for maintenance charging of your battery over long periods.
You also have to look at the size of your car battery and the battery type. Usually, a mid-sized car uses a battery of the size 40-80Ah. You also have to take in mind the kind of car battery. An AGM/GEL battery can charge up a bit faster than a regular wet battery.

What Amp To Charge Car Battery Why Charge At Two Amps
The main reason to charge at slower speeds or two amps is that faster charging can cause damage to the battery. It can buckle the battery plates, and this will make the battery not function right and can damage other areas of the car.
Also, if the battery gets hot while charging then keep an eye on it and unplug it if it gets too warm. If you have a temperature gauge and your battery gets 125 degrees Fahrenheit, then you need to stop as soon as possible.
Another final reason that fast charging is bad is that it can lead to overcharging which hurts the batteries useful life.

How To Jump A Car Battery
Be sure all accessories are off and the lights, including the interior light, are off. If you have anything on, it could cause the battery to arc while you are working with it.
Once you get down to the battery, remove the negative or ground cable first. This is always the black cable unless someone replaced the cables with the wrong colors. If you look on the top of the battery, you can see which is which the ground cable will have a negative sign and the power or positive cable will have a plus sign.
Clean the battery terminals with a terminal cleaning brush and a mixture of baking soda and water to neutralize the battery acid. If the battery terminals and posts have a lot of acid buildup, wear eye protection and a mask so the airborne corrosion does not contact your eyes, nose and mouth. Dont touch your face until after youve washed your hands.
If the battery has removable caps, carefully pry the caps off and check the level of the water. If any of the cells looks low, add distilled water only and take care to not overfill the battery. Most batteries today are maintenance-free so you wont be able to open them to check the acid level.
How Long Can You Leave A Car Battery Charging Does Leaving A Charger Plugged In Damage The Car Battery
Advanced battery chargers with battery selection and temperature probe also feature a maintenance mode – after fully recharging the battery, they switch from charging to maintaining the battery and can be left connected to the battery for a very long time.
Old style battery chargers can overcharge the battery, causing the wet/flooded batteries to lose water and AGM/Gel-Cell batteries to swell and in the end to lose the water via safety valves.
Long Story Short: Car battery charging times depend on the battery capacity, depth of discharge , battery charger charging current, battery charger type, etc.
When looking for a suitable battery charger for your car battery, go for a smart AGM battery charger that also supports the charging of other lead-acid battery types , but also if possible, that supports the charging of lithium-ion batteries as well.
Since most cars come with 50-100 Ah lead-acid batteries, in the 5-12 Amps range are perhaps the best choice for ‘quick charging’ and avoiding additional load on the batteries.

Trickle Charge Car Battery While Connected
Assuming you would like a blog post discussing the pros and cons of trickle charging a car battery while it is still connected: It is generally advisable to disconnect a car battery before trickle charging it. However, there are some circumstances in which it may be necessary to leave the battery connected while charging. For example, if the battery is in a difficult-to-reach location or if there are other electrical components that need to be powered. There are both benefits and risks associated with trickle charging a car battery while it is still connected. On the plus side, doing so can help prevent accidental discharge of the battery during the charging process. It can also make it easier to monitor the charge level and ensure that the battery does not become overcharged. However, there is also the potential for damage to occur if something goes wrong with the charger or if the charge level is not monitored carefully. In addition, leaving a car battery connected during charging can introduce unwanted voltage into other electrical components, which could potentially cause damage.
Types Of Car Battery Charger
A basic home battery charger incorporates a transformer and rectifier, to change the mains 110/220 voltalternating current to 12 volt direct current, and allows the mains supply to provide a charging current at a rate determined by the state of the battery.
In the case of a battery in good condition, the rate of charge may be around 3 to 6 amps with a normal home charger.
A battery at the end of its useful life may not accept any recharging, and will not, in any case, hold a charge.
Some chargers are fitted with a high and low switch to give a choice of two charging rates – typically 3 or 6 amps – in case you want to give the battery a short overnight boost at 6 amps rather than a longer charge at 3 amps.
Many have a charge indicator which may be a warning light, or a gauge showing the charge rate in amps.
Note that the mains lead on all chargers should be fused. If it is not, use a three-pin fused plug. As an extra precaution, fit a line fuse cable lead to the battery.

Why Do Car Batteries Fail
There are different reasons behind a drained or failed car battery. Here are some of them:
- Your battery may be experiencing charging failure. Expectedly, your battery should be charging while you are driving. But if you dont drive long distances that often, there is a likelihood that it wont get charged by the alternator.
- If you use the in-car features over time while the car is not in motion, your battery can get discharged. Using the air conditioning or listening to the radio or doing both drains the battery fast.
- When youre in a hurry, you tend to forget to turn the headlights off. In this case, theres a huge possibility that your car battery will get drained. This is especially true if you leave it on for hours. This is why most car manufacturers, if not all, have an automatic shut-off feature for the headlight.

If The Battery Won’t Hold A Charge It’s Time To Replace
Replacing a battery isn’t very difficult and can be done at home. As long as you have the proper safety equipment it’s low risk. While you’re taking the old battery out, it’s worth noting to not put new batteries on concrete as it drains them.
Replacing your battery at home can be dangerous if not done properly. When you’re starting make sure you have the proper safety equipment on and proper tools on hand. Disconnect the positive lead first and then the negative. Once you have fully removed the battery from the car, then place the new one in its place. Connect the negative lead first and then connect the positive lead. Make sure all connections are tight and start your car to make sure the battery works and stays charged.
If you replace your battery at home the only cost to you should be the cost of a new battery. New batteries run between $90 and $200 depending on the brand. The whole process should take around 10 minutes to make sure all connections are tight and secure.
Charging Almost Completely Discharged Car Battery
Sometimes car’s battery gets discharged down to almost 0 volts and in such condition, many jump starters and battery chargers cannot detect the battery and cannot help the user jump-start the car or recharge the battery .
Note: discharging the lead-acid battery that low can damage the battery easily, but if the battery is revived quickly, one can restore it probably to its 90-95% nominal capacity, sometimes even slightly more. But, it should be avoided as much as possible.
But, if that happens, there are several options, including:
– get a that allows the user to override the safety features of the jump starter and force a jump start – again, this is NOT a situation that should be happening on a regular basis, but it can be a lifesaver. After jump-starting a car, let the car recharge the battery by driving it around for at least 60-120 minutes.
– get a car battery charger that can revive and recharge highly discharged batteries. When such mode is activated, the battery charger pumps a current of certain amperage into the battery regardless of how low the voltage is and after some time measures the battery’s voltage – these cycles can be repeated several times until the battery’s voltage reaches a certain threshold, after which the battery is charged using standard charging modes.
