In general, the more mAh and the longer the battery capacity or battery life. A higher number means that the battery can store more energy, so it has a higher capacity. To my astonishment, the Galaxy M31 lasted more than 28 hours on a single charge. I charged the device at PM and left it while I had dinner, took a bath, and did some house chores. It took at least three hours to fully charge the device from 15 to 95 percent, using its 15W fast charging adapter via USB-C.

It is rated at 6v output, but is showing Is this usual to this type charger?
It is specifically for NiMH charging on the label, so maybe the circuitry turns up the voltage at initial hookup? I just bought this to charge a 4 pack of ma AA size batteries. The charger is very warm to the touch with a red charging LED showing. No instructions came with it. BatteryStuff Tech I cannot confirm if that behavior is normal since we do not sell that particular model charger. I recommend checking with the manufacture of the charger for technical help. Matt Great article.
My question … our video baby monitor came with three 1. We charge them using the supplied cable that just plugs into the handheld monitor. The batteries that came with the monitor are slowly dying so I would like to replace them.
BatteryStuff Tech Yes. However, some brands may have higher capacity than others. It will run your monitor for longer than say a mAh battery. Is it safe to use 4 alkaline 1. BatteryStuff Tech Please refer to technical help from Kodak for the answer to your question. Steven Very useful info — thanks. Two seem fine. Is it common to have very different performance within a group bought in the same package?
Also, I doubt I have charged them even 75 times, after mostly using them in digital cameras, Over a two year period. Is there any justification to complain to the retailer? But this does not give your situation any less validity. Have you measured the voltages of the batteries? Beatlearl I had to bookmark this site because I know smart when I see smart and after reading some of the articles on your site you guys are smart. Yes, before you use your new NiMH batteries for the first time you need to charge them fully.
After using it and wondering why the battery was already low, I looking in the manual and am now charging it fully. BatteryStuff Tech Not charging full capacity and discharging in the first initial uses can cause the memory effect. Closely monitoring the capacity of the batteries would be the way to determine if there was any negative effect. Plz Help me with the exact time!!!
BatteryStuff Tech At what rate does your charger charge at? Amin Which is the best battery mAh or mAh? Can i charge mAh battery in this charger? BatteryStuff Tech I am not familiar with the battery charger you mentioned, so I cannot answer that question.
But the higher the mAh rating on a battery is, the more capacity it has. This translates to longer runtime for your application before needing to recharged again. I would like to thanks you for giving wonderful understanding. BatteryStuff Tech Since we do not sell that specific charger, I cannot confirm if it will be safe to use on a mAh battery.
BatteryStuff Tech This questions is like saying your cars holds 20 gallons. How long does it take to refill it?
That depends entirely on how much is left and the rate the fuel flows through the nozzle at the gas station. As long as it takes? Usually a smart charger will have some light indicator informing you when the battery is fully charged. The result is 5.
They are new, so I wanted to fully charge them. Is this normal? BatteryStuff Tech I recommend you measure the resting voltage of your battery pack.
This will tell you the state of charge of the battery. Bob Measuring a battery at rest will not tell you the state of charge. You can read 1. If you want to measure voltage do it under load, believe me I know over 30years in the electrical trade. EnewsDigest Thanks for the excellent article and detailed reply to all our doubts. My question is if I can measure the mAh remaining in a 1. The idea is that, then I can exactly recharge for a specific period of time without over charging the battery.
Say for example, if I know that mAh is remaining I can charge for two hours with a charger with mA output. Or chargers are designed to use specific capacity? BatteryStuff Tech If the voltage is nominal and the chemistry matches, you can tehcnically use the same charger. But keep in mind the charge rate is like current flow. If you have a larger capacity battery, it may take much longer to bring the charge up. Or if the current is too much for a small battery, it can damage it.
Ineed to calculate scenarios, such as drive a 1 watt load for certain number of minutes etc. A battery with the specifications you provided will have. With your battery you could run a 1 watt load for about 30 minutes, though a little less, like 20 mins, would be recommended.
Vicki Wow! This is very helpful and interesting info. Thank you for taking the time to educate us about these things. Warmly, Vicki. I knew they were used for the 2-way radios but I wanted to check before using them in my headphones. I wonder if they heat up…? JanD I purchased a Coldheat chargable glue gun and the 4. BatteryStuff Tech Some manufacturers send there battery packs only partially charged, and require you to charge the battery prior to use.
Knowledge Base Home. Copy Link. Q: What does NiMH stand for? Q: What is meant by battery memory? Q: What is the mAh rating mean? Q: What is the best application for NiMH batteries? Q: How many times can a NiMH battery be recharged? Q: What applications are not good places to use NiMH batteries?
Q: Can I use a higher rated mAh battery in my electronic device i. A: Never mix batteries from different manufacturers Never mix batteries of different capacities Never mix batteries of different chemistries, i.
Q: When I receive my batteries do I need to charge them? Q: Is there a difference in chargers. They can be charged up to times and last longer than alkaline or NiCd batteries. One set of relatively inexpensive NiMH rechargeable batteries can save you from buying thousands if throwaway alkaline batteries. The mAh capacity rating refers to the storage capacity available for a particular battery. A battery with a capacity rating of mAh could deliver a current of mA for one hour.
Higher mAh ratings for the same battery type will generally mean longer run times. This does not apply when comparing different types of batteries. This means that you may not be able to predict how long your electronic device will run just by looking at the capacity rating of a battery.
When powering high drain electronic devices like digital cameras, computer peripherals, or portable music players, an alkaline battery will only deliver a small fraction of its rated capacity.
But when it comes to actually powering an electronic device like a digital camera, the NiMH batteries will often run the device for three or four times a long. Alkaline batteries have a high rated capacity, but they can only deliver their full capacity if the power is used slowly.
