Decoding Production Date of Topla Energy 73Ah 630A Battery: Resting Voltage 12.47V Concern

Hello.
I recommended a Topla battery to a friend, the battery after bringing it from the store had a resting voltage of 12.47V
I am looking on the internet how to read the date of manufacture of these batteries and I can not come across, but I suspect that the battery may not be the freshest?

This is a Topla Energy 73Ah 630A battery

The date of production won't do much. You would need to know when the battery was flooded with electrolyte.

Topla uses a 14-digit code: third-fourth symbols - year of manufacture, fifth and sixth - week number this year. For example, connection F 1150200941864 means that BATTERY r was released in January (second week) 2015.

You must know when the battery was filled with electrolyte.

Topla states that there is a 14-digit code on the battery from which the date of manufacture of the battery can be read. Unfortunately, but there is no such code, there are months 01-12 and in three rows 17, 18, 19. And how to check the date of manufacture here? It should be better labelled, and even when the battery was flooded with electrolyte, because I don't know when it was actually manufactured or flooded with electrolyte. For me this is very important, because I don't even know how long this battery has stood in the shop, and it shouldn't have stood more than 5 months. Someone should control this, the markings and the length of time it has been in the shop. A battery works differently from 3 to 6 years, if it has stood in the shop for 2 years, and we do not know this, then the battery can work well for us after purchase for 1 year. After all, such a cheap battery is not. For example, there is a bar code on the Topla, when scanned it shows the website address and that's all, and there is no date of manufacture. Someone is being dishonest here. Topla is a Slovakian manufacturer, it sends batteries, then all the more someone should make sure that the date and the pouring of the first electrolyte are very clearly visible, and if not, return to the manufacturer. Let him start exemplifying a solid delivery, because nobody will buy a cat in a bag!!!

I use this code, only it is not on the battery anywhere. As a foreign manufacturer, he should have all the batteries shipped back to him, then maybe he would put in a solid marking: FIRST FLOODING WITH ELECTROLYTE, CLEAR DATE OF PRODUCTION, DATE OF STORAGE BY THE SHOP. Later it turns out, that after purchase the battery worked for us only 1 year, because it was lying somewhere in the shop for 3 years. Batteries usually work well for 3-6 years, six years is really a success when it works so much, but I got a Warta battery, which worked more than 6 years, only that I took great care of it, especially in winter it was very well protected against frost, and for that it repaid me with long work. This is the way it should be, the customer has the right to see all the inscriptions on the battery and not to look for where and in what place are the signs of flooding, production and storage by the shop!!!
