Most NiMH batteries are 1.2 volts, but some can be as high as 1.5 volts.
You’ll need to know the capacity of your battery, which is measured in milliamp hours (mAh). The higher the mAh, the longer your battery will last before needing to be recharged. Finally, you’ll need to decide what type of charger you want to use.
There are two main types of chargers:
Fast chargers: Fast chargers will charge your batteries in a shorter amount of time, but they can also overheat and damage your batteries if used improperly.
Slow chargers: Slow chargers take longer to charge your batteries, but they’re much safer and won’t damage your batteries if used correctly.
If you’re using a NiMH battery, you’ll want to charge it at a rate of 1/10 its capacity. So, if you have a 2000mAh battery, you’ll want to charge it at 200mA.
7.2V NiMH Charge Rate
If you’re like most people, you probably think that the only way to charge a 7.2V NiMH battery is to use a charger specifically designed for that purpose. However, there are actually a few different ways that you can charge this type of battery, and each has its own advantages and disadvantages. The first method is to use a standard household charger.
This is probably the easiest and most convenient way to charge your battery, but it’s also the slowest. It will take several hours to fully charge your battery using this method, so it’s not ideal if you need to use your device immediately after charging. The second method is to use a car charger. Most car batteries have a voltage of 12 volts. However, some can have as low as 10 volts or even 8 volts.
This is a faster way to charge your 7.2V NiMH battery, but it’s not as convenient as using a household charger. You’ll need to have access to a car in order to use this method, and you’ll also need to be careful not to overcharge your battery. The third and final method is to use a specialized NiMH charger.
These chargers are designed specifically for charging NiMH batteries, and they’re much faster than both household and car chargers. They can usually charge your battery in just a few hours, so they’re ideal if you need to use your device immediately after charging. All three of these methods have their own advantages and disadvantages, so it’s up to you to decide which one is best for you.
NiMH Charge Rate Calculator
As we all know, NiMH batteries are becoming increasingly popular in a variety of applications. One of the main reasons for this popularity is their high charge rate capability. Unfortunately, many people are still unaware of how to properly calculate the charge rate for their NiMH batteries.
This blog post will aim to provide a detailed explanation of how to do just that! The first step is to determine the capacity of your NiMH battery. This can be done by measuring the voltage across the battery terminals with a voltmeter.
Once you have this measurement, divide it by the rated capacity (in mAH) of your battery pack. For example, if your measured voltage is 1.2V and your rated capacity is 2000mAh, then your charge rate would be 1.2/2000 = 0.0006C. Now that you have determined your charge rate, it’s important to understand what effect this has on your battery pack’s life span and performance.
In general, charging at higher rates will decrease the life span of your batteries but increase their performance in terms of discharge rates and cycling ability. Conversely, charging at lower rates will increase the life span of your batteries but decrease their performance slightly. So there you have it!
A quick and easy guide to calculating the perfect charge rate for your NiMH batteries!
Charging Voltage for 1.2V NiMH Battery
Charging Voltage for 1.2V NiMH Battery If you have a 1.2V NiMH battery, you need to charge it with a voltage that is 1.2 times the battery’s capacity. So, if your battery is 1000mAh, you would charge it at 1.2 x 1000 = 1200mA.
It’s important to use the correct charging voltage for your batteries, as using too high or too low of a voltage can damage them. When in doubt, always err on the side of using a lower voltage – your batteries will charge more slowly but they’ll be less likely to be damaged.

How to Know When NiMH Battery is Fully Charged
If you’re using a NiMH battery, it’s important to know when it’s fully charged so you can get the most use out of it. Here are a few tips on how to tell when your NiMH battery is fully charged:
|Check the voltage||When the voltage of a NiMH battery drops below 1.2 volts per cell, it needs to be recharged. You can check the voltage of your battery with a voltmeter.|
|Look for a change in color||When NiMH batteries are first charged, they’ll be pale green or yellow. As they charge, they’ll turn darker green or brown. Once they’re fully charged, they’ll be almost black. |
|Listen for a change in sound||When NiMH batteries are charging, you may hear a faint hissing sound coming from them. Once they’re fully charged, this sound will stop.|
Traxxas NiMH Battery Too Low to Charge
If you’re like most RC enthusiasts, you’ve probably experienced the frustration of trying to charge a Traxxas NiMH battery that’s too low. It’s a common problem, but there are a few things you can do to fix it.
First, make sure that the charger is set to the correct voltage. Most Traxxas batteries require an 8-cell charger, so be sure that’s what you’re using. If your charger is set to 6-cells, it won’t put out enough power and the battery won’t charge.
Second, check the connections between the charger and the battery. Make sure they’re tight and secure; sometimes a loose connection can cause charging problems.
Finally, try charging at a lower rate. If your charger has a “fast” setting, try switching to “slow” or “trickle.”
This will take longer, but it may be just enough to get the battery up to where it needs to be for proper charging. If all else fails, consider replacing your Traxxas NiMH battery with a new one. They don’t last forever, and after years of use, they may simply be past their prime.
A fresh battery will give you back the performance you expect from your RC car or truck.
NiMH Charging Voltage
The NiMH Charging Voltage is a measure of the voltage required to charge a NiMH battery. The standard charging voltage for NiMH batteries is 1.2 volts per cell. This means that if you have a four-cell NiMH battery, you would need to charge it at 4.8 volts.
If you are using a charger that does not have an adjustable output, you will need to make sure that the charger is set to the correct voltage. Many chargers have an automatic setting for NiMH batteries, so you may not need to worry about this. However, if you are using a manual charger, it is important to set it to the correct voltage.
Charging your NiMH battery at too high of a voltage can damage the battery and shorten its lifespan. Therefore, it is important to use a charger with adjustable output or make sure that your manual charger is set to the proper NiMH charging voltage.
How to Charge a Nimh Battery Without a Charger
If you’re like most people, you probably use a NiMH battery charger that came with your purchase of rechargeable batteries. But what if you don’t have a charger or can’t find one? Is it possible to charge a NiMH battery without a charger?
Yes, it is! All you need is a power source that supplies enough current (in milliamps) to charge the battery. The voltage does not need to be exact but should be close to 1.2 volts per cell.
For example, if you are charging an AA-size NiMH battery, it should be around 1.2 x 2 = 2.4 volts. Here’s how to do it:
1) Find a power source that supplies the right amount of current and voltage. A 9-volt alkaline battery is often used for this purpose because it provides a high current (around 1000 mA) and its voltage is close to 1.2 volts per cell. You can also use a 12-volt lead acid battery or any other similar power source. Just make sure that the voltage is not too high or too low, and that the current supplied is enough to charge the particular size of battery you’re using (in our example, an AA size).
2) Connect the positive terminal of the power source to the positive terminal of the battery using a wire or some other conductor. Then connect the negative terminal of the power source to the negative terminal of the battery using another wire or conductor. You’ve now created a circuit through which electricity will flow from the power source into the battery, charging it up in the process!
3) Leave everything connected for several hours until the battery is fully charged (indicated by its voltage reaching 1.4 – 1.5 times its original value). Once this happens, disconnect everything and voila – your NiMH battery is now charged without needing a special charger!
What Amp Should I Charge for My 3000Mah NiMH Battery?
If you’re looking to charge your 3000mAh NiMH battery, you’ll need an amp that can deliver at least 1.2A. That said, it’s always best to err on the side of caution and go with a slightly higher amperage to be safe. For example, a 2A charger will work perfectly fine and won’t put any undue stress on the battery.
What Setting Do I Charge My NiMH Battery?
Charging your NiMH battery is a simple process, but there are a few things to keep in mind to get the most out of your battery. The first thing to consider is the voltage of your charger. Most NiMH batteries are 1.2 volts, so you’ll want to use a charger that is specifically designed for that voltage.
You can find chargers that are adjustable, but it’s best to stick with one that is made specifically for 1.2-volt batteries. The next thing to consider is the amperage of your charger. The higher the amperage, the faster your battery will charge.
However, you don’t want to go too high or you could damage your battery. A good rule of thumb is to choose a charger with an amperage that is half of the capacity of your battery. So, if you have a 2000mAh battery, you would want a 1000mA charger.
Once you’ve selected the right charger, simply connect it to your battery and plug it into an outlet. Most NiMH chargers have a light that will turn from red to green when the charging process is complete.
What Voltage Do I Charge My NiMH Battery?
When it comes to charging your NiMH battery, the voltage you use is important. If you charge your NiMH battery at too high of a voltage, you risk damaging the battery. On the other hand, if you charge your NiMH battery at too low of a voltage, the charging process will take longer than necessary.
Ideally, you should charge your NiMH battery at 1.2 volts per cell. So, if you have a four-cell NiMH battery, you would charge it at 4.8 volts. To get this voltage, you can either use a special NiMH charger or a standard household AA or AAA battery charger (as long as it has an adjustable voltage).
If you’re using a standard AA or AAA charger to charge your NiMH batteries, be sure to set the voltage to 1.2 volts per cell before connecting the batteries. Otherwise, you run the risk of overcharging or undercharging your batteries.
Can I Charge NiMH Batteries With Any Charger?
Yes, you can charge NiMH batteries with any charger, but it is important to note that not all chargers are created equal. Some chargers are designed specifically for NiMH batteries and will provide a faster charge than others. It is also important to read the instructions that come with your charger to ensure proper usage.
NiMH batteries should be charged at a rate of 1C, or the capacity of the battery in amps. For example, if you have a NiMH battery with a capacity of 1000mAh, you would charge it at 1 amp.
