I bought an 80 Ah battery and got 60 Ah. I did 3 tests under different loads, it indicated a battery capacity of a little over 60 Ah. From the beginning, the seller did not want to accept the complaint, knowing that the costs of sending back from Europe were too high. Aliexpress demanded a test film. The seller stated that this is not a professional test. Aliexpress sided with the seller. This way, you cannot prove that you have been deceived. I do not recommend this seller. The picture shows the condition in which I got the battery.
