Hi,
I have installed solar panels and ordered this type of batteries from the image below, from PWOD seller : https://www.aliexpress.com/item/1005002287176571.html .
I waited 95 days from the moment of payment, but received bad quality.
, a number of 144 grade a batteries.
But instead I received all swollen as you can see below.
Seller said that batteries was not swollen when shipped.
It was shipped with train from Shenzhen to European Union.
I believe temperature from desert went above 80C in train and damaged the batteries.
I tested voltage and they are all around 3.29V and internal resistance checked and it is between 0.25mOhms and 0.35mOhms .
I think I will have to do a load test of 250Watts and see if voltage is sustained above 3Volts. How can I do a load test safety because I do not have a DC Load Tester with fixed power settings ?
What do you suggest I have to do ?
Request replacement cells (will that happen, is there a regulation for that ?) Anyone in the same situation with me ?
What is the solution with AliExpress for this problem ?
Thank you for the suggestions if you can help me.
