I don't know how long it will last, but if it lasts 3 years without problems I will be satisfied.

I have bought four for an electric scooter, and even though I have a steep slope in my yard, they last quite a while. I would only replace them with lithium ones.

They arrived with a voltage of approximately 12.5, with a small difference of +-0.10v and a resistance of 40ohms. They measured 100cca.
A 9-volt battery I had purchased had half the resistance and slightly more cca...
Maybe they need charging, I don't know...
Overall, I would say they are average, but let's see how long they will last... Maybe with this price, I shouldn't expect too much...
I will come back with photos... I don't have the time right now...

I charged them and one gave me 24Ω as it should and 180cca, which I think is a bit high... And the other one gave me 30Ω and 130cca. Here the resistance is a bit high but the cca are okay...
I will keep them and God willing...

Great! I got 2 batteries at 12V 7Ah. They came fully charged at 13.1V and 13.3V respectively. The smart charger didn't start charging. I performed a discharge test at 4.8A until 9.6V and they lasted 43 and 49 minutes respectively, which is around 90% of the theoretical time based on the datasheet. Not bad, and they didn't enter float charge for topping up. We'll see how long they will last. I have installed them outside the power supply, so they don't exceed 30 °C, in float charge at 13.67V.

Update: My batteries have the code FVJ28 and after contacting the company, I learned that they were manufactured in July 2022. 11 months ago. They are not exactly fresh, but they seem to be OK.

Update 2: After sitting in float charge for a few days, I measured them again with a load of a 60W car lamp with a cutoff at 9.6V, just like the previous time. They lasted longer, 56 and 54 minutes respectively. It aligns with the graphs in the datasheet. So, we're not talking about fake batteries.
