How Long To Charge Car Battery At 750Ma?
If you’re like most people, you probably don’t think much about your car battery until it dies. Then, you’re suddenly very interested in how to charge it up as quickly as possible.
Fortunately, charging a car battery is relatively simple. The most important thing to remember is to use the correct charging rate.
The charging rate is usually specified in terms of amperes (amps) or milliamperes (milliamps). The charging rate is usually printed on the battery itself, and it’s important to use this number when charging the battery.
For example, if the charging rate is specified as 750mA, that means you should charge the battery at a rate of 750 milliamps.
To calculate the charging time, you simply divide the battery’s capacity (in milliamp-hours) by the charging rate. For example, if the battery has a capacity of 3600mAh and you’re using a 750mA charger, it will take 4.8 hours to fully charge the battery.
Of course, this is only a rough estimate, and the actual charging time will depend on a number of factors, including the type of battery, the condition of the battery, and the efficiency of the charger.
If you’re not sure about the charging rate, it’s always best to err on the side of caution and charge the battery at a lower rate. Charging at a higher rate may damage the battery and shorten its lifespan.
How Long To Charge 12 Volt Battery At 10 Amps?
It really depends on the battery. If you have a standard 12 volt car battery, it should take about 12 hours to charge at 10 amps. However, if you have a deep cycle battery, it could take up to 24 hours to charge. Ultimately, it really just depends on the battery and how big it is.

How Long To Charge A Battery At 2 Amps?
This is a common question that people have when they are trying to figure out how long it will take to charge their battery. The answer to this question depends on a few factors, such as the type of battery, the capacity of the battery, and the current that is being used to charge the battery.
In general, it takes about 8 hours to charge a battery at 2 amps. This is based on the assumption that the battery is completely discharged and that the charger is able to provide a constant current. If the charger is not able to provide a constant current, then the charging time will be longer.
The type of battery also plays a role in how long it takes to charge the battery. Lead acid batteries, for example, have a lower charge acceptance than lithium ion batteries. This means that it takes longer to charge a lead acid battery than it does to charge a lithium ion battery.
The capacity of the battery also affects the charging time. A battery with a higher capacity will take longer to charge than a battery with a lower capacity. This is because there is more energy that needs to be stored in the higher capacity battery.
Finally, the current that is being used to charge the battery also affects the charging time. A higher current will charge the battery faster than a lower current. However, it is important to note that using a higher current can shorten the lifespan of the battery.
In general, it takes about 8 hours to charge a battery at 2 amps. This can vary depending on the type of battery, the capacity of the battery, and the current that is being used to charge the battery.
