Excellent video. Very clear explanation. Really helpful! Thank you
OMG this was simplest and easiest to understand explanation of how to use this device. Thank you.
Very clear and thorough explanation. Thank you!
Please don't forget to subscribe. I appreciate it.
Excellent video. Very clear explanation. Really helpful!
Glad it was helpful!
Thank you , it is a very good explained video .
Great Video thank you for posting, please keep posting so folks like me can learn, stay safe.
Thanks, will do!
Great job!
Thanks for the great, informative video. I browsed your channel and saw many interesting topics. Subscribed
Welcome aboard!
Just purchased one of these no instructions,very informative video I know how to operate now thanks
a good teacher can get things across instantly subed thankyou
Thank you. Much appreciated.
Awesome
Amazing review! Thanks. Small question can I change discharge current? If I make like 4Ohm 10W or 16Ohm 10W? Or how to do it to have about 1000mAh? So 2x bigger discharge current?
You can change it but the device will not show correct value. I don’t advise changing the charge current but To increase the discharge current reduce the large resistor value to half and make sure it is twice is large in power. Now mosfet switch that turns On and OFF the load might not be able to handle twice as much current. Very risky.
Hi I have a question, A battery have a certain amount of charge- discharge cycle where a cycle is (li-ion) 4.2v to 2.8v but most users never let the battery work to 2.8v. So if the battery is use till 3.4v then topped up each time how then do you determine what the charge cycle is?
Hi WattHour! Many thanks for the didactic video. I have a problem related to the XH-M240 - I'm trying to test some batteries (GEG212 from Leica) and when I connect it to the board, it reads 6.6V even though it should be 7.4V. If I measure it with a multimeter I get the correct voltage. Depleted batteries also show 6.6V. AAA batteries shows 1.4V. Any idea what's going on?
Hello, the module is defective. When it shows 6.6V for empty or fully charged battery, then something is wrong.
@@WattHour And yet it shows correctly 1.4v for an AAA battery...
Thank you for this. Would one be able to use this to test AA capacity (obviously the AA won't fit in the holder, but this can be bridged)?
You are welcome . Yes can test if you know the minimum voltage for the battery and can set it. The best thank you for me is to subscribe to my channel. Thanks
@@WattHour brilliant. Is there a minimum cut off voltage on the tester?
@WattHour Hi dear Ahmad , Thanks for sharing another great video. I have a question, If we have an unknown battery how can we set the cut off voltage? is there any standard cut off value for li ion batteries?
For unknown battery type it would be very hard. It would be risky to set minimum value below allowed value . It will either permanently damage or reduce the life of the battery.

According to Wikipedia, Lipo-Batteries have a Cutoff voltage of 3.3 Volts. Li Ion Batteries have a CutOff Voltage of 2.5 V.
@@gustavbroennimann7030 Thanks
Is it possible to use the 12 V Adapter power supply if the battery is not installed?
will this work with regular lithium aa rechargeable battery's that output 1.5 volts?
Excellent video. I have been using one of these testers and found it very useful. I put the power supply battery in backwards and turned the power switch on. Now it doesn't work. Can the unit be fixed please? Thanks.
Hi, I don't remember if I mentioned if there is fuse, check that and replace it. May be someone else fixed it to replay.
@@WattHour where is the fuse please?
thanks for the review. when i want to make test with 2 batteries how can i understand which one is good or bad.the result of the screen left battery or right battery or both ??
you can't test two batteries at the same time. in the first 5 minutes I explained that we check the capacity of the battery and why. your answer is there. If your battery says it is 3000mAh and when you test it and it shows 1000mAh then you know the capacity has been reduced. if the battery is very bad you will get 500mAh instead of 3000mAh or you may get 50 or 0.
In case you didn't catch it the left battery is for powering the device ,only the right is for testing
The one on the left runs the tester, the one on the right is being tested. After you test one battery, recharge it and then interchange them and test the other one.

You are very cleaver. Thanks
Basically, in order to know the capacity of the battery you just discharge it with this device and wait for the correct number to be displayed on the screen. But waiting for 7 hours is not good. What if you have to check many batteries? Spending so much time is not an option. Is there a quick way to check a bunch of batteries using this device?
the capacity unit is Ah (ampere in hour). If you have 10Ah battery, The fastest you would get is 10 hour at 1A rate or 1 hour at 10A rate. because 1x10=10. but you can have faster for example 20A in 0.5A or 40A in 0.25 hour. Now it would be very hard to have such powerful discharger. Also not all batteries allow 20A or 40A to be drained.
Yep, i got about 30, 18650s to test, this would take ages.
Can you tell us the percentage of accuracy of this battery capacity tester that you have reviewed?
I mentioned it. it uses a 5% resistor to measure the current. so 5% error.
@@WattHour This device will only give you a comparative capacity reading of cells that you test. For a "true" capacity reading you need to discharge your cell at the industry “standard” 0.2C rate. With the 10 ohm load provided, the reading will be correct only for a “1750mAh” cell. (calculations..0.2 rate for 1750 is 1750x0.2 = 350mA, assuming 3.5V during the discharge). For any other capacity, (or other assumed discharge voltage) unless you change the load resistor, you’ll need to apply a correction factor to the results if wanting to check claimed capacities.
Ok, can someone help me please. I have this same battery tested. I have 18650 3.6v 3600 mAh battery, HOWEVER when I discharge it to find out the mAh (discharge to 2.5v), it only showing 3181 mAh. Is there something wrong with it, or are the calculations wrong? Please help.
battery is bad
Can you just discharge the batteries or can you charge the two batteries?
That is exactly why I made the video. Please watch and I can guarantee that you will not have any questions after that.
Only discharge
She shows me a reading overflow 7000mAh What do I do ?
it works with more than 10ah 18650 batteries?
I have explained it. I did the calculation. See the video
@@WattHour what about XH-M239? I want to buy it
input voltage max amps?
5v max amps 9999mah
Hello, mr. Ahmad how are you. Where is channel robojax.
Hello, we are working on contents on this channel.
@@WattHour
May Allah help you, Ramadan mubark.
Model XH-M239 has an LCD display that shows battery voltage, target voltage, MA in real time, and total/cumulative Mwh. The second button from the left starts the discharge.

I wish I had seen this video before I bought one. I thought I'd give it a shot. Mistake.
