how long to charge a car battery at 50 amps
The length of time it takes to charge your car battery is completely dependent on the size or amp of your battery and the amp of the car charger you are using. So a battery that provides 48 amp hours will need 24 hours to be recharged at the rate of 2 amps per hour.

Automobile batteries commonly have a capacity of 48 amp hours.
. A marine battery that is capable of providing 100 amp hours would need approximately 50 hours to be restored to a full charge at the rate of 2 amps per hour. If your car owns a large size battery it will have a higher amp rating. Besides the internal chemistry of your car battery influences the ampere rating.
Most of the car batteries own from 550 to 1000 amperes. This means that it can deliver 1 amp per 48 hours or 2 amps in 24 hours 8 amps in 6 hours and so on. Problems are more likely to arise if you leave the charger connected long after the battery is fully charged.
For example if you had a 50 amp hour battery and a 5 amp charger it would probably take you about 10 to 12 hours to fully charge that battery from a completely dead state of charge. Charging Duration amp-hours left in the battery 10 amps of the charger Example. The ampere rating is the electrical storage capacity of the car battery.
Higher amps means a faster charge. Using a 40 amp charger on a 48 amp battery takes 12 hours to charge from empty. Charging at 50 amps is fast but stay safe.
My 15-amp charger is fine for marine or golf-cart batteries but is a little high for most car batteries. The small car battery is categorized as an RC 40-60. However it may take longer if your charger isnt compatible with the battery or if theres some underlying defect with the battery itself.
At that rate theres a risk of overheating the battery. Like a car battery of 100ah you can do the math easily. If using a low amp charger it can take up to 24 hours to charge your battery properly but a high amperage charger such as a 40 amp charger will get the job done adequately in an hour or less and will get you on.
Like the OP Im wondering if this can be used to charge a car battery. For a regular car battery that you cranked dead and it has 5 amps it would fully charge it in about 10 hours. Even a 2 amp charger will do this if it isnt regulated.
Before asking how long it takes to charge a car battery we have to look at the methods designed to make the charging process as quick and smooth as possible. If it is an older charger it would keep charging it until it boils the acid out. If we take a normal battery that has the power of 48 amps and we charge it with 1amp charger then it will take almost 48 hours to recharge the battery.
Generally it should take about 1 hour to charge a car battery at 50 amps. The average car battery will provide about 48 amp hours before it is depleted of power and a 40 amp battery charger would restore that number of amp hours in an hour or less. Generally a car battery holds 48 amps so using this amount of voltage will take up to twelve hours to reach full battery capacity.
And the ampere number depends on the size of the battery. And once the battery is around 50 charge you can switch the battery with a 2 amps battery charger. Using a 50 amp charger on a 48 amp battery takes a little less than 1 hour to charge from empty.
So a 2 amp charger will deliver 2 amp per hour to this flat battery and if it requires 48 amps that in means it needs 24 hours to fully charge. If your battery is left with 50 amp hours then the approximate duration of charging will be the amp hours left divided by 10 amp hours of the charge. The charger puts out 40 amps an hour and has to work for 12 hours to reach 48 amps.
A 40 amp battery charger is an extremely powerful device. This is because a 2-amp battery provides only 1 ampere per hour. This is just a guestimate.
Without causing undue stress you should know what the possible risks are. Is it safe to charge a car battery at 50 amps. If the battery is fully empty then you just need to double these times to see the amount of time your charge will.
The charger can charge a 50 discharged medium-sized battery which is RC 60-85 in about 3 to 4 hours or a large-sized battery which is RC 85-190 in approximately 4-7 hours. Charging a battery with a car battery charger enough that it can start the car engine will take around 2 to 4 hourscharging a car battery at 4 to 75 amps is the safest and most efficientcharging a car battery 4 things to remember. Furthermore I have a 12V 100-amp ConverterCharger PowerMax PM3 Series is the unit if anyone is curious.
In those instances it could take up to 5 hours. Aside from jump starting the fastest but not always the most efficient method you can also consider using a reliable car battery charger. Most people seem to recommend 10-amps max.
A battery charger with low amp charging such as 2 amps can recharge a battery in one to two days. For charging car starter batteries. It will take 5 hours to completely charge your car battery 50 amp hours 10 5 hours.
