Is A Higher Amp Charger Ok To Use For My Car Battery
I would heavily discourage using a charger greater than 10 amps when charging a car battery.; In fact, I would stay in the 2 to 8 amp range. I think 5-amps is the sweet spot when it comes to vehicle batteries. If you have a truck, you might get away with a 10 or 15 amp charger, but a lower one would still be healthier for your battery.
Batteries will tend to overheat, overcharge, and boil electrolyte off when they are receiving an amperage greater than 25% of their total amp hour rating.;;
Most car batteries are in the range of 40 to 70 amp hour equivalency.; Truck batteries and other larger vehicles or those with lots of electronics might get up in the 80 amp hour equivalency range or higher.
If you have a 50AH battery and you hook a 30 amp charger to it, you are risking overheating it, warping the plates, and losing electrolyte solution through evaporation due to electrolysis.; It also increases the production of hydrogen gas and hydrogen sulfide .;;
A slower charge gives the plates in the battery more time with less stress to convert electrical energy from your charger into chemical energy.;;
It might take an extra hour or two, but its worth it for a healthy battery.
If youre looking for a solid charger and/or maintainer, I recommend this 5-amp charger from Amazon.; It is gentle on your car battery, can charge it overnight, and can be left connected indefinitely for long-term storage!
Using A Speed Or Trickle Charger
Check The Output Power
Ideally, you want to slow charge car battery components if youre without a charger. The trickle effect ensures that the battery doesnt overcharge, fume or outright explode. Because of these volatile conditions, Battery University;suggests always monitoring a charging session.
Check your output power on the power source by using your wire probes. Verify the voltage and current. While you have the probes out, check the voltage on the questionable car battery. Youll have an idea of how long the charging session will take with these values in mind.

Getting Ready To Charge
Before we get into how to charge a car battery at home, you need to know how to prepare to charge the battery. It is very easy to get a good shock if the battery does have some juice. Before you even get started, if you have to remove the battery from the vehicle to charge it, be sure you have the tools for the job. Some batteries are easily accessible; however, some are under or in the fender and some may even be in the trunk or under the seat depending on the make and model of your vehicle.
How To Charge Your Car Battery With A Battery Charger
Charging your vehicles battery is a much more efficient way of keeping your car running than jump-starting it once the battery has gone flat. Its also much better for your battery in the long term.
Thankfully, with a battery charger to hand, its not too difficult to do it yourself. Just follow the simple steps below.
Check your charger
Always make sure youve read the operating instructions on your specific charger, and make sure that its fit for purpose.
If your vehicle has Stop/Start Technology, it will be fitted with either an EFB or an AGM battery , so youll need a smart charger to charge these types of battery safely.
Before you start charging, ensure the battery terminals are clean and free from corrosion. If not, clean the terminals before charging, as this helps to ensure a good connection.
With that prep work done, you can now connect your charger to the battery. Some manufacturers may advise disconnecting the battery during charging, so always check your owners handbook before you continueand follow their recommendations.
Ensure the charger is switched off, then you should connect the red positive lead to the positive terminal on your battery. Always connect the black negative lead to the negative terminal on the battery last. Ensure the charger is situated away from the battery and switch the charger on to commence charging.
And thats it. Your vehicle should be charged and ready to go.

Why Do Car Batteries Go Flat
There are a number of reasons for a flat car battery, the most common being old age more than five years for a car battery should be considered a good life cycle. Essentially, a car battery is only used for cranking the car engine when it is initially started. However, over time as it ages, it will experience a natural fall off in its capacity to hold its charge, and will go dead more frequently. There are other reasons for a battery running flat, including;
·;;;;;;;Frequent short journeys do not allow the battery to fully recharge
·;;;;;;;The use of onboard electronic devices when the car is not running
·;;;;;;;Even leaving ;an interior light on overnight when the vehicle is not in use could drain a battery
·;;;;;;;Extreme temperatures, both hot and cold
·;;;;;;;Fitting the wrong battery, one that cannot meet the demands of the car
·;;;;;;;Overcharging a battery
How To Estimate The Charging Time Of Your Car Battery
Let’s say you want to do it at a different setting other than the 50AMPS rating. The first thing to do is to check your battery’s CCA ratings and RH ratings. Find these numbers on the top of your battery. You will also find there an estimate for the charging time of your battery for whether it is still 50% dead or completely dead.
For the estimate below, we will use the setting 1.5AMPS or the AH rate for the charger. The AH , which is the unit used by car battery makers, is the rating that refers to the amount of charge a charger can replenish within a battery for one hour. This does not include inefficiencies. For this estimate, the inefficiency rate we will use is 0.8.;
First, we take a 32AH battery. Battery manufacturers say that it takes 13.5 hours for it to be fully charged from 50%. Since this is half-charged, we divide 32 by 2, and get 16AH, which is the amount to be replaced.
Divide that by 0.8 ; we get 20AH, which is what is needed to come from the charger.;
Divide further by 1.5AMPS which is our AH rate; we arrive at 13.33 hours which is the same charging time indicated at the battery label.
Keep in mind this is applicable only for half-full batteries. For full charging from 0%, just double the resulting figure, and that will be the full-charge time for your battery.

Can Inverter Charge Car Battery
A power inverter, or inverter, is a power electronic device or circuitry that changes direct current to alternating current . The resulting AC frequency obtained depends on the particular device employed. Inverters do the opposite of converters which were originally large electromechanical devices converting AC to DC. The input voltage, output voltage and frequency, and overall power handling depend on the design of the specific device or circuitry. The inverter does not produce any power; the power is provided by the DC source. A;power inverter can be entirely electronic or may be a combination of mechanical effects and electronic circuitry. Power inverters are primarily used in electrical power applications where high currents and voltages are present; circuits that perform the same function for electronic signals, which usually have very low currents and voltages, are called oscillators. Circuits that perform the opposite function, converting AC to DC, are called rectifiers.
A car battery is a rechargeable battery that is used to start a motor vehicle. Its main purpose is to provide an electric current to the electricity-powered starting motor, which in turn starts the chemically-powered internal combustion engine that actually propels the vehicle. Once the engine is running, power for the car’s electrical systems is still supplied by the battery, with the alternator charging the battery as demands increase or decrease.

Find The Battery And Clean The Terminals
- Open the hood of your vehicle if you haven’t already.
- Look for two terminals on the battery, marked positive and negative.
- Remove the red plastic cover from the battery’s positive terminal .
- Use a small wire brush to carefully clean any corrosion from both terminals to ensure a good connection with the charger clips.

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.
Q: How Can I Tell If My Car Battery Is Fully Charged
Ans: By measuring the voltage of your car battery, you can tell if your car battery is fully charged or not. In order to tell your car battery, you need a voltmeter. A voltmeter reading will display your car battery volts. If the voltmeter displays a voltage of about 12.7 to 12.9 volts, this means your battery is fully charged. Frequently checking the battery is a good practice for car owners. If the voltmeter is displaying voltage anywhere between 12.4 and 12.8, this voltage means your car battery is in good condition. If your car batterys voltage shows above 13.8, that means your car battery is overcharged. Overcharging a car battery is not good for your car battery.

Why Car Batteries Do Go Flat
There are many reasons for batteries to go flat or lose charge. Basically, a car battery is only used to crank the engine. But like most batteries, once it reaches the end of its lifespan, it loses its capability to hold its charge and will often go dead. Other factors can also shorten the life batteries:
Two things are required to charge a car battery; a voltage source powerful enough to move current through battery, and time. The more current you push into a car battery, the faster you can charge it. However, charging a battery at too high a rate can lead to overheating.
The time/rate a car battery recharges depends on many factors, like if the battery is cold. Check the temperature of the battery during charging. Once gets too hot, stop charging and continue when it cools down.
