Testing and Charging Board for Apple Batteries MDTL0248

[@mynameisyeff7939]

Thank You, I have been trying to find info on how to use this in English.

[@chana100red]

Good video and explanation as I have one of those testers with lack of understanding since suppliers do not supply you with manuals. Thumbs up

You’re awesome man! Thank you! I just got this board and had no idea what I was doing, now I have a basic understanding. My iPhone 6s Plus wouldn’t recognize the charging port, I replaced charging port put it all back together and still nothing. I’m guessing it software, so I need enough juice to try and recover the phone.

Can you use house power voltage to charge batteries on this boards?. im using desk top computer to get power to board. I mean usb cable to wall plug or is it to strong?

[@Official_Flip_B]

I have the K-9208. The box came with the plastic tray ripped. I don’t want to store it in that packaging. Do you store it another way? Have you seen any type of shells that maybe someone has 3D printed for the device?

I just got a Kaisi board and my 6p battery connector does not fit properly or stay on the connector. I am not sure which is at fault the battery or the Kaisi board. Any ideas?

[@rebmcitp]

Any suggetion where can I buy these premium batteries !

What are the dangers of activating a battery that has gone down to a low charge level to the point it won’t charge again without an activator?

[@mark01337]

Amazing. So much utterly wrong and sometimes even dangerous information in a single video. 1:35 The 5v 'known' voltage combined with the battery voltage makes 4.12 volts? And you can calculate based on that? Nonsense. It's a Li-Po charging circuit. It's supposed to provide about 4.2 volts to charge the battery. Go beyond that and you'll toast your battery. Luckily it's limited to 4.25v, otherwise you would have had fireworks @2:22. 2:26 Adjust the amperage going in, without changing the voltage or duty cycle? Dream on. You'd get a Nobel prize for that. All you're doing is messing up your calibration... 2:40 What you're stating about USB and the maximum power is hopelessly outdated. And even in 1998, it was wrong. This device uses resistors to communicate the current it needs. Completely within USB specs. 3:28 No, the circuit on top of the board is regulating the charge. Trigger the protection circuit in the battery itself and you'll either have a dead battery or have to wait till the circuit resets. 4:12 Trickle charging is what you do with a NiCd or NiMH battery. Trickle charge a Li-ion / LiPo battery and you'll get lithium plating followed by fireworks. Lithium batteries CANNOT be safely overcharged. 4:43 Yes, it does mean the battery is bad. When a LiPo / Li-ion cell reaches such low voltages, permanent damage has occured. In fact, the battery should now be considered dangerous, which is why the protection circuit is trying to block you from toasting yourself. 5:26 An "Open short"? Really? This is where I stopped watching.

Mark Laagland make a video to serve the need then..... why bash the dude if you don’t or won’t do a video on the board and how to use it?

[@MrTuteeeeeeeeeeeeeee]

Luis Canino he doesn’t have to, and he’s not bashing, misinforming people is an actual hazard it’s ok to point things that are wrong

[@raidone7413]

@@MobileStoreAdda very informational, thanks! Im getting into phone repair and this is my first battery activation video ive watched. The more information discussed, the better. It gives me a better idea. I dont really know half the stuff youre talking about yet, but it still helps. hopefully no one takes too much offense

[@vitaminprotin]

I want this where i can get it

[@vinniepooh]

Please could You explain: If we have normal battery lets say iPhone 6 Plus the same 3 batteries that You test, could You write what is a normal battery, I mean where have to be the voltage between and also where have to be the ampere between? So the battery written voltage is 3,82 Volt. maybe let's say 2,80 & 3,82 Volt. Also the same for the second battery, I payed attention that in this case the amperes was more than we expected around 2 amp. So in this situation what I suppose to change for better performance? Adjust the ampere to 1 Ampere? Or voltage or whatever You think. I found this video very informative and its blessing to see it in Pro Repair technician and how operates. Any advice will be highly appreciated!!!

[@kasundinesh4463]

Is this same theory of dc power supply?

[@lastshot2325]

They say premium replacement but you shown 2 out of 3 was bad

[@zenlife5703]

Very very helpful, thank you so much

[@newgoverment1875]

How about if voltage is zero?

[@sanjusanju6621]

How much this

[@czechreme1591]

Thanks.

Damn who is shoveling in the back ground annoying

[@Ivar1231]

Dude that’s someone using a tape gun

[@nick6834]

Great instruction! Horrible camera person! Is it that hard to hold a camera still while filming. Hope to see more videos from you but, please correct this problem.
