Here is a website I have ordered from before and the results that they claim are correct from what I have seen from the batteries I have bought from them
BatteryHookUp.com
https://batteryhookup.com/collection...odem-batteries
I have test about 5 battery packs ( out of 15 battery packs I bought) and have had very good results and so far have not found any bad cells
I have also bought these battery packs before on EBay and they are a good source for a battery case that holds 18650 batteries however... -
Order my parts from mobilesentrix.com and iPhone batteries have been excellent. Recently got 3x bad A1534 (2015) batteries. All would work until ~30-40+% and drop to < 10% instantly. Typical sign of cheap batteries.
Perhaps the less popular A1534 model's aftermarket batteries are more source limited. Just find it surprising quality from mobilesentrix (usually fairly high quality aftermarket parts) have been so poor.
BTW, this isn't the only defective parts I've had from mobilesentrix. Amongst others including iPad Air touch screen and A1989 touch bar (display was... -
Hello, all.
Cyberpower Battery Backup Unit.
I bought two new ML18-12 batteries through Amazon (They have already refunded my money for the two batteries as we thought the batteries might have been bad.)

Checking the voltage, it was down to 22v.
I quickly removed everything... -
Hi friends of electronics
What you see in the video and pictures attached is the circuit for charging the batteries of a DC motor.
The problem is that this circuit cannot charge the batteries (3 1800mAH NiMH batteries) any more. When the circuit was OK, its green LEDs lit up one at a time to show that the batteries have charged more. But now that the circuit is flawed, LEDs light up as you see in the video and at the same time successive beeps are heard.
Please help me fix this circuit.
