Battery Charge Time Calculator-Calculating, Time and Advantages
Batteries are very essential in our everyday survival. We need them to power our gadgets such as phones, laptops, watches, cars, and even houses. For this reason, every detail such as charge time is very important because they help us plan. But the problem is batteries have different charge times making it difficult for us to guess. Other factors can affect the charging rate of the battery.
Let's look at an example by calculating the battery charging time of a lead-acid battery. Let’s use the following formula.
How long does it take to charge a battery charging time?
You should not continue charging a battery that is overheating. This can cause fatal accidents. So if you feel that the battery is hot when you touch it, then you have quit. On top of that, you should consider charging your batteries at a slow charge rate. For example, 10 A is considered as slow charging while 20A and above is considered an as fast charge.
Fast charge is not recommended because it reduces the lifespan of a battery. Before determining the battery charging time, you have to determine the capacity. You can easily find this info by looking at the manufactures specs. Then multiply that capacity by 0.6 which is the standard reserve capacity. The next step is measuring the open-circuit voltage. You do this by simply using a voltmeter
Replace the battery by 36 amp hours if you normally use the 10A rate. Not that the chargers do not output exactly 10A. So your battery may last more than 12 hours on the charger. Wait for the battery to cool and measure it again using a voltmeter to confirm whether it's fully charged. Then look up the charging time by using your open-circuit voltage.
Always wear protective gear while you are charging and discharging batteries. As we have discussed the charging time of a battery can be affected by the following factors.
- Charger type e.g. Fast or slow
- Charge state. E.g. Discharged, partially charged or fully charged
If all these calculations are hard for you to grasp, then you can use an online calculator. As long as you can tell the capacitance of your battery, charging rate, and charge state then a calculator will be the perfect solution for you.
What are the advantages to use a battery charge time calculator?
Using a battery charge time calculator has so many advantages. First, it's very easy to use than going the manual way. You can get your battery charging time by just inserting some values. Leave the other work to the calculators. . Another notable advantage is that using a battery charge calculator saves time. Not so many people can afford to waste their time on calculations every time they are in search of battery charge time.
A battery charge time calculator is also more accurate than calculating the old-school way. It's easier to make errors when calculating manually than using the manual way. Also, the calculator makes work a lot easier. For instance, when you are trying to calculate the battery charge time for many batteries. If you decide to calculate the old fashioned way then you will end up consuming a lot of time and most probably making a lot of errors.
Knowing the battery charge time is very crucial because it helps you maintain good care. Monitoring the charge time also helps to understand the behaviour of your battery. So you will know when it has started degrading so that you can prepare yourself to buy another one. There are two ways in which you can use to find the battery charge time. By calculating it manually or by using a battery charge time calculator. Both ways are effective but using a calculator is easier. It's very hard for you to make mistakes by using a battery charge time calculator. Also if that you are dealing with so many batteries the calculator is the best way to go.
